The Anker PowerHouse 521 is a compact portable power station with a 256Wh LiFePO4 battery, a 300W AC inverter and a 20V max solar input. It runs small devices, lights, laptops and phones, and its LiFePO4 cells are rated for roughly 3,000 charge cycles, far longer than the lithium-ion packs in many small rivals. It suits campers, van dwellers and anyone who wants quiet backup power for a few essentials, but it cannot run appliances that draw more than 300W.
