A modern portable power station should be equipped with long-lasting batteries that recharge quickly. Anker 757 Portable Power Station uses a bi-directional or "two-way" smart inverter for a safe and fast recharge. 

Unlike other power stations in the market that need multiple hours to recharge, Anker 757 PowerHouse can be charged from 0% to over 80% in just 1 hour. Rapid recharge is possible through HyperFlash technology, using a bi-directional inverter that draws power from the standard AC plug at faster speeds.

The design uses fewer materials to reduce carbon emissions while maintaining fast recharge speeds.
