Until recently, you had to protect portable power stations from the elements. They are essentially boxes filled with electricity, after all, and we all know that water and electricity don't mix. The problem is that if you want to take your power station outdoors, there's a good chance you'll run into water, whether it's from rain, snow, rivers, lakes, mist, or fog.

Thankfully, there's now a game-changer in the market: the Bluetti AC240. This incredible portable power station has been meticulously designed and rigorously tested to be water and dust-resistant. And it does its job at charging up your devices too: in our lab tests, it was the most efficient large-size portable power station (1,100-2,100 Wh), earning it a ZDNET Lab Award.
