Unlike bulkier panels I’ve tried before, this one folds down to a tiny size, making it a no-brainer to toss into your backpack.

The real game-changer is the dual USB ports—QC3.0 and PD2.0—so I could charge my phone and tablet simultaneously without slowing down. I tested it on a sunny afternoon, and even in partial shade, it kept up surprisingly well, thanks to its 24% conversion rate.

Still, for $75.99, this panel offers a high level of versatility and efficiency that’s hard to beat for backpackers and off-grid explorers.
