More Details on Our Top Picks
Nature’s Head Self Contained Composting Toilet with Close Quarters Spider Handle Design
This model stands out for its combination of low-maintenance operation and large capacity, making it ideal for two-person off-grid setups. Compared with the Separett Tiny, it offers a higher capacity with no frequent emptying, but it lacks the odor-reducing ventilation fan found in the Separett Tiny. Its odorless operation and easy installation are key advantages, though its no-maintenance claim might oversimplify some user expectations for long-term use. The large capacity and straightforward design make it a reliable choice for those seeking a hassle-free, self-contained solution.
Pros:- Odorless operation enhances comfort in enclosed spaces
- Large capacity reduces frequent emptying for two users
- Easy to install and empty, simplifying maintenance
- No ongoing maintenance needed after initial setup
Cons:- Lack of active odor control features like ventilation could be a concern in very tight spaces
- No specific cons mentioned, but its size and capacity may be overkill for single users
Best for: Couples or small households needing a durable, low-maintenance composting toilet with minimal upkeep
Not ideal for: Solo users or small-scale campers who prefer more portable or less permanent options, as its size may be less suited for very limited space
- Warranty:5 years
- Capacity:Large
- Installation:Easy to install
- Maintenance:No maintenance required
- Odor Control:No odor
Our verdict“This toilet makes the most sense for couples or small households seeking a reliable, low-maintenance composting option with minimal odor issues.”
Sun-Mar Excel NE Composting Toilet
Compared with the Nature’s Head, the Sun-Mar Excel NE is designed for off-grid living with the advantage of processing waste quickly without water or electricity, making it highly eco-friendly. Its NSF certification adds confidence in safety and performance, yet it offers a limited capacity suitable mainly for small households or occasional use, unlike the larger Nature’s Head. Its compact form and odorless performance make it ideal for remote locations where minimal infrastructure exists. However, its design prioritizes environmental sustainability over high-volume capacity, which could be a drawback for larger families.
Pros:- Operates entirely without water or electricity, perfect for remote sites
- Odorless and environmentally friendly operation
- Compact and easy to install in limited spaces
- NSF certified for safety and performance
Cons:- Limited capacity makes it less suitable for frequent or multiple users
- Designed primarily for small households or occasional use, not high-volume scenarios
Best for: Small households or individuals seeking an environmentally friendly, waterless composting toilet that requires no electricity
Not ideal for: Large families or high-traffic off-grid sites requiring higher capacity or frequent emptying
- Brand:Sun-Mar
- Model Number:CSEL-01001W
- Number of Items:1
- Included Components:Drain Hose, Bowl Liner, Footrest, Rake, Microbe Mix, Hardware Kit, Vent Pipe
- Certification:NSF Standard 41
Our verdict“This pick is ideal for eco-conscious individuals or small households prioritizing waterless, odorless operation in remote settings.”
Separett Weekend Prime Urine-Separating Compost Toilet
The Separett Weekend Prime excels in environments where quiet, manual operation is essential, such as remote cabins or emergency setups. Its urine separation system reduces odor and makes waste management more straightforward compared to the Sun-Mar Excel NE, which processes waste more fully but requires more space and infrastructure. The manual handling involved in waste disposal is a tradeoff for its simplicity and durability, making it less ideal for high-traffic households. Its compact, robust design and no-electricity requirement make it well-suited for harsh or remote conditions.
Pros:- No electricity or water needed, perfect for off-grid environments
- Silent operation with effective odor reduction
- Durable, compact, suitable for harsh conditions
- Simple manual operation with internal urine diversion
Cons:- Requires manual waste handling and composting management
- Limited capacity may mean frequent emptying in high-use scenarios
Best for: Wilderness cabins, emergency setups, or users who prefer manual, low-tech solutions without electricity
Not ideal for: Busy households or campers expecting high usage, as the capacity may require frequent emptying
- Model Number:1172-02
- Components Included:Liquid container, samples of biobags, absorb and bio drain cleaner tablets, solids container, toilet, user and installation manual
Our verdict“This toilet is best for those who need a durable, manual solution in remote or wilderness settings, accepting some manual labor for its simplicity and reliability.”
Separett Tiny Self-Contained Urine-Separating Compost Toilet
Compared with the larger Weekend Prime, the Separett Tiny offers a space-saving design with built-in ventilation, making it ideal for tiny homes, RVs, or boats. Its odor-free operation thanks to the fan and removable containers simplifies waste disposal, although it requires manual emptying of both liquids and solids. Its compact size and sturdy construction make it a practical choice for small living spaces, but it may fall short for households larger than two or those with high waste volume. The included view screen and biodegradable bags add to its user-friendly features, but regular maintenance is necessary.
Pros:- Very compact, ideal for small spaces
- Odor-free with built-in ventilation system
- Removable, easy-to-clean containers
- Durable with spare parts support
Cons:- Requires manual emptying of both liquid and solid waste containers
- Less suitable for households with more than two occupants
Best for: Small-space dwellers such as tiny home residents, RV travelers, or boat owners who value space efficiency and odorless operation
Not ideal for: Large families or extended off-grid setups where capacity and ease of waste handling are more critical than compactness
- Type:Self-contained composting toilet
- Urine container capacity:2 gallons
- Design:Waterless, urine-separating
- Ventilation:Built-in fan
- Material:Biodegradable bags for solids
- Country of design:Sweden
- View screen:Includes
Our verdict“This toilet is perfect for small living spaces where space and odor control are priorities, but not for large or high-usage households.”
TROBOLO WandaGO Composting Toilet, Portable Outdoor Camping Toilet, Urine Diverting Dry Toilet with Height Adjustment
The TROBOLO WandaGO is designed to meet the needs of outdoor enthusiasts who require a lightweight, portable composting toilet. Its adjustable seat height and ergonomic design prioritize user comfort, while the odorless operation and spill-proof features make it reliable for camping, hiking, or emergency use. Compared with the Separett Tiny, it offers greater portability and support for higher weights, but it has a limited number of uses before requiring emptying and lacks accessories for waste disposal. Its simple, travel-ready design makes it a strong option for on-the-go use, though it’s less suited for regular household use or high-frequency needs.
Pros:- Lightweight and highly portable for outdoor use
- Adjustable seat height for comfort
- Odorless and spill-proof for outdoor conditions
- Supports up to 330 lbs, durable for rugged use
Cons:- Limited number of uses before needing to empty
- No included accessories for waste disposal or extra capacity
- Requires periodic maintenance for odor control
Best for: Campers, hikers, or emergency responders needing a portable, odorless toilet that supports outdoor mobility
Not ideal for: People planning long-term off-grid living or large groups, as its capacity and convenience are limited with frequent emptying required
- Dimensions:12.3″ (H) x 15.0″ (D) x 13.4″ (W)
- Weight:10.4 lbs
- Seat Height:12.0″ or 17.2″
- Supports:up to 330.7 lbs
- Uses:10-20 urination, 8-12 defecation
Our verdict“This portable toilet excels for outdoor activities and emergency situations, offering odorless operation and comfort, but isn’t designed for long-term or high-usage scenarios.”
Cuddy Composting Toilet – Odorless, Waterless & Self-Contained for RVs, Vans, Boats, Tiny Homes & Off-Grid | 3.9 Gal, 12V Fan, Carbon Filter, No Chemicals, Easy Clean
The Cuddy Composting Toilet stands out for its odorless operation, thanks to a built-in fan and carbon filter, making it ideal for those who prioritize a fresh environment in off-grid settings. Compared with the Sun-Mar GTG, it offers a more self-contained experience without the need for external chambers, although its 3.9-gallon capacity might require more frequent emptying in high use. Its compact design and minimal maintenance make it suitable for tiny homes and RVs, but it relies on a 12V power supply, which could be a limitation off-grid. The removable solids bin simplifies cleaning, yet its capacity could be a drawback for larger households or extended stays without frequent disposal.
Pros:- Odor-free operation with integrated fan and filter
- Easy to clean with removable solids bin
- Waterless and chemical-free, suitable for eco-conscious users
Cons:- Limited capacity requires frequent emptying for heavy usage
- Dependent on 12V power, which may not be available everywhere
Best for: Off-grid dwellers and RV owners who need a reliable, odorless, and low-maintenance toilet
Not ideal for: High-traffic households or those with limited access to 12V power sources, as capacity and power needs may be restrictive
- Capacity:3.9 gallons
- Power:12V
- Material:Plastic
- Features:Odorless, waterless, self-contained, includes carbon filter
Our verdict“This pick suits those seeking a compact, odorless composting toilet with minimal maintenance for off-grid or mobile use.”
Xastro Complete Composting Toilet Kit with Urine Diverter & Toilet Seat
The Xastro Complete Composting Toilet Kit offers an all-in-one solution, with a durable mirror-finish ABS seat and a comprehensive set of accessories that make installation straightforward for those comfortable with DIY projects. Compared to the Sun-Mar GTG, which is more of a permanent setup, Xastro’s kit is designed for flexible installation and portability. Its included urine diverter and discharge hose simplify waste separation and disposal, but the pre-drilled holes and assembly steps could pose challenges for less experienced users. This kit is ideal for those who want a customizable, ready-to-assemble composting toilet with a sleek look, though it may require some modifications to fit specific setups.
Pros:- All-in-one kit simplifies setup
- Durable ABS material with easy-to-clean finish
- Includes urine diverter and discharge accessories for versatile waste management
Cons:- Pre-drilled holes may not align with all setups
- Assembly and cutting require some DIY skill and tools
Best for: DIY-minded off-grid homeowners or tiny home builders who want a customizable, all-in-one composting solution
Not ideal for: Users seeking plug-and-play or minimal assembly options, as installation involves cutting and fitting
- Openings:365mm x 276mm
- Material:Mirror-finish ABS
- Includes:Urine diverter, toilet seat, filter, discharge hose
- Installation:Requires cutting and assembly
Our verdict“This kit makes the most sense for those comfortable with DIY projects who want a durable, customizable composting toilet for off-grid living.”
OGO Origin Urine-Diverting Composting Toilet – Odorless 12V RV & Van Toilet
The OGO Origin excels in tight quarters like vans and boats, with its compact 15″x16″ footprint and sleek Scandinavian design. Its urine-diverting system and electric agitator mean less fuss and odor, making it a top choice for mobile living. Compared with the Sun-Mar GTG, which is bulkier and more suited to stationary setups, OGO’s smaller size and electric features enhance convenience. However, its limited liquid capacity of 2.4 gallons means it requires frequent emptying, and it depends on a 12V power source, which might not always be accessible in remote off-grid locations. Its modern style appeals to users seeking aesthetics and function combined.
Pros:- Compact size fits small spaces
- Odorless operation with urine diversion
- Electric push-button agitator simplifies use
Cons:- Limited capacity requires frequent emptying
- Dependent on 12V power supply
Best for: Vanlifers, boat owners, and tiny home dwellers needing a compact, odorless, electric composting toilet
Not ideal for: Extended off-grid stays without reliable 12V power, or households with high waste volume
- Dimensions:15″x16″
- Capacity (liquid):2.4 gallons
- Uses per full tank:25–30
- Power:12V
Our verdict“This toilet suits mobile users who want a sleek, odorless, and electric composting solution for small spaces.”
OGO NOMAD Portable Composting Toilet for Camping – RV, Van & Boat Toilet
The OGO NOMAD offers true portability, with no electricity or plumbing needed, making it ideal for remote camping and rugged outdoor environments. Its urine-diverting system and lightweight design allow for easy transport and setup, comparable to the Sun-Mar GTG in waste management but without the need for installation or power. The limited capacity means frequent emptying, and users must purchase compatible composting bags, which adds ongoing costs. This toilet is perfect for those who prioritize simplicity and mobility over long-term capacity, especially where power sources are unavailable.
Pros:- No electricity or plumbing required
- Lightweight and portable for easy transport
- Odor-free with urine diversion
Cons:- Limited capacity needs frequent emptying
- Requires purchasing and replacing composting bags
Best for: Campers, remote explorers, and boaters seeking a lightweight, no-fuss composting toilet

- Included Components:Compostable bags, Coco coir, Spray bottle
- Weight:Lightweight
- Capacity:Limited
Our verdict“This portable toilet is best for outdoor enthusiasts who need a simple, odorless solution that works in remote environments.”
Sun-Mar GTG Self-Contained Urine Diverting Compost Toilet
The Sun-Mar GTG features two chambers for separating solid and liquid waste, enabling continuous use without frequent dumping. It installs quickly and runs on minimal power, making it suitable for tiny homes, cabins, and boats. Compared with the Cuddy model, which is more compact but less flexible, GTG’s dual-chamber design allows for extended use without manual intervention. Its waterless operation and high capacity make it appealing for off-grid scenarios, although its bulkier size and less traditional appearance might be less attractive for some users. Its separate chambers require some understanding of waste management but offer a low-maintenance experience once set up.
Pros:- Easy to install with quick setup
- Unlimited capacity with dual chambers
- Waterless, low-energy operation
Cons:- Bulkier size may be less suitable for small spaces
- Requires 12V power supply
Best for: Tiny home dwellers and remote cabin owners seeking a low-maintenance, continuous-use composting toilet

- Dimensions:19.8″x15.75″x24″
- Capacity:Unlimited
- Power:12V fan
- Includes:Compost Magic, hardware kit
Our verdict“This toilet is ideal for those wanting a durable, low-maintenance system with high capacity in remote or off-grid locations.”
Separett Villa Urine-Separating Compost Toilet
The Separett Villa excels as a reliable, waterless composting toilet that separates urine efficiently, making it ideal for off-grid homes where water conservation is critical. Compared to the Separett Tiny, it offers a higher capacity and less frequent maintenance, but it may require more effort to install indoors without prior experience. Its design minimizes water use and avoids chemicals, which appeals to eco-conscious users. The main tradeoff is that it might need adaptation for indoor use in some settings and lacks detailed odor control features. Still, its high-capacity and versatility make it well-suited for larger off-grid residences or remote cabins. This model makes the most sense for those prioritizing long-term sustainability and minimal maintenance in a residential setting.
Pros:- Waterless operation conserves water resources
- High-capacity design for extended use without frequent emptying
- Suitable for various off-grid and remote applications
- No chemical additives or mixing needed
Cons:- May require adaptation for indoor installation in some environments
- Limited information on odor control features
Best for: Off-grid homeowners seeking a durable, high-capacity composting toilet with minimal water use.
Not ideal for: Small cabins or tiny homes with very limited space, as installation can be complex and capacity might be overkill.
- Brand:Separett
- Model Number:1255-01
- Number of Items:1
Our verdict“This toilet is best for off-grid residents needing a large, low-maintenance, waterless system with proven durability.”
Separett Tiny Urine-Separating Compost Toilet, Tube Version
The Separett Tiny provides a compact, waterless solution perfect for tiny homes, RVs, and boats where space is at a premium. Its urine diversion and silent ventilation make it odor-free, a step above larger models like the Villa in tight quarters. While its small footprint is ideal for limited spaces, it also means limited capacity, requiring more frequent emptying in high-traffic situations. The flexible installation options, including a 16-foot ventilation pipe, enable versatile placement, but it necessitates an external urine management system, adding complexity. This pick is better suited for short-term or occasional use rather than continuous occupancy. It’s a smart choice for mobile or minimalist users prioritizing space savings and odor control over capacity.
Pros:- Waterless and odor-free operation
- Compact, space-saving design
- Flexible installation options for various small spaces
Cons:- Requires external greywater or urine holding tank
- May need electrical power for ventilation fan
- Limited capacity makes it less suitable for high traffic
Best for: Tiny home dwellers, RV owners, or boaters needing a space-efficient, odor-free composting toilet.
Not ideal for: Families or off-grid residents with high daily waste volume, as capacity is limited and external urine handling complicates usage.
- Type:Urine-separating compost toilet
- Design:Compact, waterless
- Operation:Odor-free, silent
- Installation:Flexible, up to 16 ft ventilation piping
- Includes:6.6 ft urine hose
- Warranty:5 years
Our verdict“This toilet is ideal for mobile, small-space environments where odor control and compactness outweigh capacity concerns.”
Nature’s Head Self Contained Composting Toilet with Foot-Spider Handle
The Nature’s Head is a self-contained composting system designed for off-grid and outdoor use, with a unique foot-spider handle that simplifies operation. Its eco-friendly design reduces environmental impact and is ideal for remote cabins or camping setups. Unlike the Separett models, it doesn’t require external venting or urine diversion, making it more straightforward to set up in rugged environments. However, it demands regular maintenance and proper composting procedures, which can be a hurdle for less experienced users. Its self-contained nature makes it less suitable for large families or high-traffic situations. This toilet is best for eco-conscious users comfortable with composting protocols in outdoor settings.
Pros:- Eco-friendly and self-contained design
- Easy to operate with foot-spider handle
- Suitable for outdoor, camping, or remote settings
Cons:- Requires routine maintenance and proper composting knowledge
- Not suitable for indoor or traditional bathroom environments
Best for: Eco-minded outdoor enthusiasts, campers, or remote cabin owners comfortable with composting maintenance.
Not ideal for: Urban or indoor applications where aesthetic appeal and low maintenance are priorities, as it’s primarily designed for outdoor use.
- Brand:Nature’s Head
- Model Number:NH030-2020
- Number of Items:1
Our verdict“This composting toilet is best for outdoor use by those willing to manage composting processes regularly.”
Thinktank Composting Toilet, White
The Thinktank offers a user-friendly, airtight composting experience with a urine-diverting system that accommodates both men and women comfortably. Its design minimizes odor through a patented trap door and ensures easy cleaning by containing waste in a bag, setting it apart from other models like the Sun-Mar Excel, which relies on a more mechanical composting process. While setup of the air intake and exhaust can be a bit involved, it provides a cleaner, less odorous experience. The convenience of bag-contained waste makes it suitable for temporary or portable off-grid applications but may become inconvenient for continuous, long-term use. It’s a solid choice for users prioritizing comfort, simplicity, and odor control.
Pros:- Designed for comfort and ease of use for both genders
- Minimal odor with airflow and trap door system
- Easy to clean with waste contained in a bag
Cons:- Requires setup of air intake and exhaust pipes
- Waste disposal involves handling bags, which may be inconvenient
Best for: Off-grid users who want straightforward, comfortable waste handling with minimal odor during occasional use.
Not ideal for: High-traffic households or long-term installations where managing disposal bags becomes cumbersome.
- Color:White
- Type:Composting Toilet
- Features:Airtight, urine diverting, easy to clean
Our verdict“This toilet suits users seeking a comfortable, odor-reducing system with simple waste containment for occasional or portable use.”
Sun-Mar Excel Composting Toilet
The Sun-Mar Excel stands out with its NSF Standard 41 certification and patented Bio-drum, which accelerates composting, making it suitable for off-grid locations where quick turnaround is needed. Unlike the Thinktank, which relies on bags, the Excel’s self-contained design simplifies waste management, especially in permanent installations. Its easy installation and maintenance make it appealing for users who want a reliable, low-hassle composting system. The main tradeoff involves potential ongoing maintenance and higher upfront costs, which might deter those seeking a budget solution. This system shines in fixed, long-term settings where fast, certified composting is a priority.
Pros:- Self-contained and easy to install
- NSF Standard 41 certified for safety and sanitation
- Fast composting with patented Bio-drum
- Low odor with proper ventilation
Cons:- May require regular maintenance and servicing
- Higher initial investment compared to simpler models
Best for: Off-grid locations requiring certified, fast composting with minimal ongoing fuss.
Not ideal for: Temporary or mobile setups where portability and quick setup are more important than long-term certification.
- Type:Self-contained composting toilet
- Certification:NSF Standard 41
- Features:Easy to install, patented Bio-drum for fast composting
Our verdict“This is an excellent choice for permanent off-grid sites that need certified, rapid composting with reliable sanitation standards.”
How We Picked
Our evaluation focused on key factors that matter most for off grid living: performance and reliability, ease of use, build quality, maintenance requirements, and value for money. We prioritized products that excel in odor control, durability, and user convenience, especially in remote settings where service options are limited. The ranking reflects a balance between affordability and feature set, with a bias toward units that are straightforward to operate and maintain over the long term. We compared user reviews, technical specifications, and reputation to identify models that stand out across different use cases, from portable camping toilets to permanent off grid systems.
Factors to Consider When Choosing Composting Toilets For Off Grid Living
When selecting a composting toilet for off grid living, consider several critical factors that influence daily use, maintenance, and long-term satisfaction. The right choice depends on your specific needs, space constraints, and lifestyle. Understanding these considerations helps prevent common pitfalls like odor issues or excessive upkeep, ensuring your off grid setup remains functional and comfortable.Capacity and Size
Assess how much capacity you need based on your household size and usage frequency. Larger units with bigger waste tanks reduce emptying frequency but take up more space, which might be a concern in small cabins or tiny homes. Portable models are ideal for camping or temporary setups, but may require more frequent servicing. Consider both the physical footprint and how often you’ll need to empty or service the unit to match your off grid lifestyle.
Odor Control and Ventilation
Effective odor management is vital for comfort and discretion, especially in enclosed spaces. Many models incorporate fans, carbon filters, or urine separation to minimize smells. Urine-separating toilets often excel here because they keep moisture and odor separate, reducing the need for complex ventilation. However, units with active ventilation fans require power, so ensure your off grid power source can support this without draining batteries or solar panels.
Ease of Maintenance and Cleaning
Simpler maintenance encourages regular use and prevents hygiene issues. Look for models with removable waste chambers, easy-to-clean surfaces, and minimal parts that require servicing. Some units feature self-contained designs, while others might need more hands-on effort. Consider your comfort level with cleaning routines and whether you prefer a low-touch process or are willing to commit time to upkeep.
Power Requirements and Energy Use
Many composting toilets rely on electric fans or pumps, which need a reliable power source like solar or batteries. If your setup is off grid, prioritize models with low power consumption or manual operation options. Some units are entirely manual, eliminating electrical needs but potentially complicating odor control or maintenance. Matching power needs to your off grid system is critical to ensure consistent operation without overtaxing your energy supply.
Budget and Long-Term Value
Price varies significantly across models, often reflecting capacity, features, and durability. While cheaper units might suffice temporarily, investing in a higher-quality model can save money and hassle over time by reducing maintenance and replacement costs. Consider your long-term needs and whether a higher upfront investment offers the durability and performance required for off grid living. Balancing cost against expected lifespan and functionality leads to more satisfying choices.
Frequently Asked Questions
How often do I need to empty a composting toilet for off grid living?
The frequency depends on the size of the waste chamber and usage levels. Most units need emptying every few weeks to a couple of months for moderate use, but high-traffic setups may require more frequent servicing. Choosing a model with a larger capacity can extend this interval, reducing maintenance trips. Regular monitoring is key to prevent overflow and maintain odor control, especially in off grid environments where service options are limited.
Are urine-separating composting toilets more effective at controlling odor?
Urine-separating models often provide superior odor control because they keep moisture and smell away from the composting chamber. By diverting urine, these toilets reduce the likelihood of odors emanating from the waste, especially in enclosed spaces. However, they are slightly more complex to operate, requiring proper urine diversion and sometimes additional maintenance steps. Proper use and ventilation enhance their effectiveness, making them a preferred choice for many off grid users.
Can I use composting toilets without electricity?
Yes, some composting toilets operate entirely manually, relying on natural ventilation or urine separation without electrical components. These models are ideal for off grid living if you want to minimize power dependence. However, they may lack active odor control systems like fans, which can make odor management more challenging. Weigh the tradeoff between energy independence and odor control when choosing a non-electric model.
What maintenance tasks are involved with composting toilets for off grid use?
Maintenance typically involves emptying waste chambers, cleaning surfaces, and replacing filters or fans if applicable. Some models require regular mixing of compost or adding bulking material. Proper maintenance ensures odor control, hygiene, and smooth operation. Choosing a model with straightforward access to waste chambers and easy cleaning features can significantly reduce the time and effort involved, which is crucial for off grid setups where professional service isn’t readily available.
How do I decide between a self-contained unit and a split-system composting toilet?
Self-contained units combine all components in one compact design, making them ideal for small spaces and portability, such as camping or tiny homes. Split-system models separate the composting chamber from the toilet seat, offering more capacity and potentially better odor management, suited for permanent off grid installations. Your choice depends on space constraints, maintenance preferences, and whether mobility or capacity is a priority. In general, self-contained units are simpler to set up, while split systems provide more flexibility for larger or more permanent setups.
Conclusion
For those seeking the best overall performance in an off grid setting, the Nature’s Head Self Contained Composting Toilet offers reliable durability and user-friendly operation. Budget-conscious buyers will appreciate the Separett Tiny Urine-Separating Toilet for its affordability and compact size. If you prefer a premium, feature-rich option, the Sun-Mar Excel NE provides impressive capacity and odor control for larger households or long-term off grid living. Beginners and those with limited space should consider portable models like the OGO NOMAD, while more experienced users demanding maximum efficiency might opt for split-system setups. Tailor your choice to your specific needs, space, and energy availability for a satisfying off grid experience.
