The Anker Everfrost Powered Cooler keeps our food and beverages cool as we rumble down dusty desert roads or kick our feet up at the campsite for some well-deserved rest and relaxation. The beefy 299Wh battery provides cold storage for up to 42 hours in the 30L size, and 35. 8 hours in the 40L size, allowing us to crack a cold one or cook with fresh ingredients when we reach the campground for the night. The battery can be recharged from wall outlets, car sockets, USB-C devices, and even solar panels to ensure we never run out of juice, and so our juice stays cold. The EasyTow handle quickly converts into a small tabletop for meal prep, and the large six-inch wheels roll over rocky ground so we can set up camp on any patch of flat ground we can find.
