🏕 Cooling Solutions for Every Adventure
Tent Camping & Rooftop Tents
The Transcool E3 is ideal for tents and rooftop tents, providing cool airflow while you sleep. Lightweight and portable, it won’t take up valuable sleeping space. Perfect for campers who rely on 12V power or solar setups.
Caravans & Camper Trailers
When you’re off-grid in a caravan or camper trailer, battery life matters. The E3’s ultra-low current draw keeps you cooler without draining power. Rugged and compact, it’s the go-to option for travelers who can’t always rely on mains A/C.
RVs & Off Grid Boondocking
Boondock with confidence. The Transcool E3 runs from power stations, vehicle batteries, or solar panels, delivering personal cooling when rooftop air conditioning isn’t an option. Designed for long stays without hookup power.
Truck Sleeper Bunks
Truck drivers trust the E3 for comfort during rest stops. The cooler’s compact size fits easily into sleeper bunks and runs straight from the 12V or 24V socket. Quiet operation ensures a restful sleep, even on long-haul breaks.
Dogs & Pets
Keep your pets safe and comfortable at camp. The E3 provides airflow and evaporative cooling for dogs and cats in tents, crates, or RVs. Always ensure shade, ventilation, and fresh water — never leave pets unattended in hot conditions.
4WD, Van Life & Overlanding
For overlanders, Van Lifer’s and 4WD adventurers, the E3 is built tough for rugged environments. Small enough to pack anywhere, it runs from your battery system or solar kit, making it a reliable cooling solution far off the beaten track.

Perfect for keeping your pets coolWhether you’re battling the heat in a tent or struggling to sleep in a boat or RV, one of Transcool’s 12 volt units is for you.
Transcool delivers cooling when and where you need it, a portable evaporative cooling system like no other, it’s the best way to stay comfortable no matter what kind of heat you’re up against.
One of the Transcool’s greatest strengths is its versatility, delivering real comfort in a small package.
Its small size means it will comfortably fit into even the tightest cabin, tent, caravan, or RV to keep you cool on even the hottest day. Choosing an evaporative system over a simple fan means you won’t just be blowing hot air into your face. The 12 volt Transcool’s efficient design means you’ll get hours of use from its internal 1.7 liter tank.
For those times when you need cooling for the maximum amount of time, we also supply a free 5 liter external tank free with every Transcool unit.
Please remember that the 12 volt Transcool (or any other brand of 12 volt portable evaporative cooler) won’t necessarily cool down an entire room, car or cabin to a set temperature like a refrigerated Air Conditioner that requires electricity or engine driven compressors for cooling! Transcool simply performs best in blowing air directly on your smaller spaces like caravans, cars, tents and boats.
Be very wary when you see cheaper portable evaporative coolers with often misleading claims of being able to ‘cool your room for pennies’!
NOTHING GOOD IS CHEAP, AND NOTHING CHEAP IS GOOD!
It is the best portable ‘spot cooler’ to provide personal relief by blowing cool air over the user whilst in front of the units-A great companion for comfort on a hot summer's night! We even have pet air conditioners if you’re looking to make sure your furry companions aren’t sweltering through the heat.
