The new Anker coolers notably feature faster and more flexible solar charging options. Apart from a 100W solar source, you can charge it from a wall socket, a carport, or a USB-C 60W port.
You can recharge it from zero to 100% in under four hours with a 100-watt solar panel under ideal conditions. Meanwhile, it can also be charged decently faster from other sources, like a wall socket, a carport, and a 60W USB-C port.
History: Anker crowdfunded the EverFrost coolers on Kickstarter in 2023, with shipping to backers that year. The EverFrost is now a current Anker SOLIX product, sold on Anker SOLIX’s EverFrost page, where you can check current pricing and availability. All the models come with a 299Wh battery pack.
