FLAMECOOL started with a simple frustration: relying on bags of ice to keep a camping cooler cold. Founder Travis Esliger is building and testing the prototype in public rather than presenting an unfinished concept as a finished production product.
The current unit remains in prototype development. Final performance, runtime, cooler compatibility and production specifications will be confirmed through testing before production.
PROTOTYPE DEVELOPMENTReal build progress · testing before productionTraditional coolers can mean repeated ice runs, less usable food space, draining meltwater and dealing with wet packages. FLAMECOOL is being developed to provide active off-grid cooling without making bags of ice the primary cooling source.
FLAMECOOL is being developed for people who need dependable cooling beyond the reach of household power. The goal is simple: turn your cooler into a flame-powered refrigerator without replacing the cooler you already own. Instead of building another large appliance around a fixed cabinet, FLAMECOOL is designed as a compact refrigeration module that works with compatible standard-size coolers. That approach can make cold storage more practical for camping, overlanding, remote worksites, hunting trips, fishing camps, emergency preparation, cabins, and other places where access to electricity may be limited or unavailable.
Traditional camping coolers rely on ice, while powered portable refrigerators depend on batteries, vehicle charging systems, solar equipment, generators, or electrical hookups. FLAMECOOL is being developed around a different source of thermal energy. Its purpose-built fuel system is intended to support extended off-grid operation while keeping the refrigeration hardware portable enough for outdoor use. The design is focused on useful cold storage rather than adding unnecessary electronics, complicated controls, or a permanent installation to the cooler.
For customers, the practical value is flexibility. A familiar cooler can remain useful as a normal insulated cooler when FLAMECOOL is not attached, while the refrigeration module is intended to provide active cooling when needed. That means the system can travel with camping equipment, move between suitable coolers, and serve as part of a broader emergency or off-grid setup without requiring a dedicated refrigerator for every trip.
FLAMECOOL uses a purpose-built thermal refrigeration system to move heat out of the cooler. The operating principle is designed for compact, off-grid refrigeration while keeping proprietary component details and production specifications protected during development. The result is a system intended to use a controlled flame as its primary energy input rather than depending on an electrical hookup, large battery bank, or generator.

The sealed refrigeration system transfers heat out of the cooler while the candle supplies the thermal input.

The proprietary FLAMECOOL Candle is designed to burn continuously for up to 5 consecutive days, providing a sustained heat source for extended off-grid operation.
Cold storage matters for more than convenience. On longer outdoor trips it helps protect food, keep drinks cold, reduce dependence on repeated ice runs, and make remote travel easier to plan. During a power outage or emergency, portable refrigeration can also provide another option for preserving temperature-sensitive supplies when conventional household refrigeration is unavailable. FLAMECOOL is being developed with those real-world situations in mind.
The system is also intended for people who travel light and value equipment that can perform more than one job. Campers and overlanders may want a cooler that works normally during short outings but can gain active refrigeration for longer stays. Hunters and anglers may need cold storage far from services. Remote crews may need a compact solution that can be transported with existing gear. Off-grid users may simply want another refrigeration option that is not tied to the electrical grid.
FLAMECOOL remains a prototype product, so final performance, compatibility, operating procedures, production materials, and specifications will be confirmed through validation and testing. The development priority is to create a practical, durable, portable refrigeration system while protecting the proprietary engineering that makes the concept unique. Early-access members will receive development updates and advance notice as testing progresses toward production.
The limited preorder is $399 CAD + applicable taxes for the FLAMECOOL portable refrigeration system and one purpose-built FLAMECOOL Candle. Every successful payment receives a numbered position from #1 to #100.
FLAMECOOL is still a prototype. Final production specifications, compatibility, performance and delivery timing remain subject to validation and production readiness. The preorder page provides the current terms before payment.
