Anker SOLIX EverFrost 2 40L

The Anker SOLIX EverFrost 2 40L is the only cooler here that doesn't use ice, earning top marks for Cold Performance and Versatility & Features via an active cooling system that drops contents from 77°F to 32°F in roughly 15 minutes. At $599, it is the most expensive cooler in the lineup and, at 51 lb empty, the heaviest—nearly double the weight of the Tundra 65, making it impractical for backpacking but ideal for van-lifers with solar setups, where its battery can be recharged in 6 hours via a 60W panel.
