The official Anker storefront over at Amazon is now offering its EverFrost 33L Powered Cooler for $549 shipped once the on-page $250 off coupon has been clipped. You’d typically need to set aside $799 for this model, but the large coupon slashes over 31% off. This undercuts the previous low we’ve tracked by $50, making this the best time to pick up one of these. Now that summer weather is in full swing, Anker’s portable cooler is ready to amplify your upcoming adventures with up to 42 hours of cooling, a detachable 299Wh battery, and support for solar charging. With it, you won’t need to buy ice or worry about the wasted storage because of it. Using the Anker app on your phone you can dial in all of your preferred settings, which is just as futuristic as it sounds. Plus, the 299Wh removable battery wields 60W USB-C and two 12W USB-A ports so you can easily top off any devices you have along with you.
