I’ve been testing portable power stations ... two main questions came into focus: Do these power stations really hold as much energy as they say they do? And how much of that energy is leaking out ...

When the Grecell T-1000 was originally launched, it was seen as a cheap, versatile, and feature-packed portable power station ... and it can output up to 1000W with a 2000W surge capacity ...

Armed with a 293Wh lithium-ion battery pack, the Explorer 300 features 2 Pure Sine Wave AC outlets that deliver stable and safe 300W power. The portable power station weighs only 7.1 pounds.
