Anker 757 Portable Power Station weighs 43.9 lb / 19.9 kg, which is heavier than some other similar products. There are several reasons that can explain why this happens.
1. It is equipped with LiFePO4 Batteries, which have a 6 times longer lifespan and can last 3,000+ cycles.
2. To protect the power station, PowerHouse uses metal frames to protect the battery pack and inverter board to make it more durable.
3. PowerHouse has a bi-directional inverter that’s equivalent to integrating the supplied AC adapter into the product. With a fast charging speed, the power station can be fully recharged within 1.5 hours.
