It's been interesting to see Anker slowly move into the off-grid market with their Anker Powerhouse lineup which goes well beyond what a small battery backup is capable of as far as power storage and even includes AC outlets and capable solar charging as well. This is perfect for people who are camping but I would also lump in people with large properties/farms where getting power everywhere isn’t possible and also people in the trades which may not have power available where they are working. Anker’s latest product falls into this same category, their EverFrost Powered Coolers integrate large battery capacity into a powered cooler to keep things cool or frozen for up to 42 hours depending on the size you go with. With summer coming up I can’t think of a better time to be able to put one to use, so today I’m going to check out the new EverFrost Powered Cooler 40 which is the 43L capacity to see what it is all about.
