The best cooler can manage duties for a few days, at best, and beyond that it’s all water. If you’re overlanding, camping, or just hitting the open road for days on end, you might want something like the National Luna line of portable refrigerators and freezers, which employ their rugged in-house compressor that can take on bumps and jostles like a champ, as well as automatically toggle between 100V and 240V and utilize both AC and DC power. It spools up in Turbo Mode to cool quickly and then drops to a more efficient setting to reduce power consumption while keeping the goods cold. The portable appliances are made with corrugated stainless steel on the outside with aluminum lining and copper piping for ideal temperature retention and evenness. Features include a digital thermostat, a programmable controller, and secure buckles for all size models (40/52/55/65/85/12 liters). Suddenly, your coolers just became portable camp seats.
