If that's not enough, you can add up to six battery packs to expand the capacity to 26.9 kWh, which is enough power for a week. The Anker Solix F3800 is built with Anker's InfiniPower technology to last over a decade, even with daily use. The power station also features EV-class LFP batteries, durable components, and an intelligent temperature control system.
