Max Burton Portable Fridge/Freezer
Admittedly it’s a little retro-looking. But the Max Burton Portable Fridge/Freezer does something most coolers can’t: actively cool its contents, as its name would suggest. A side-mounted LED panel and controls allow you to set the temperature anywhere from -7° F to 53° F, the fridge’s built-in compressor maintaining the set temperature indefinitely — or at least as long as your vehicle’s engine still has some juice. When battery voltage gets low it’ll automatically shut off to avoid needing to boost the car later. The 53 quart unit isn’t quite as lightweight as most coolers, though, with a dry weight of about 47 pounds.
