If your idea of “roughing it” involves a river crossing and zero bars of signal, the NESTOUT 10,000mAh Power Bank ($55) is your new tactical best friend. Built to military standards, this half-pound battery survives drops, dust, and those “don’t ask” moments involving a puddle and your dignity.

It fast-charges two devices simultaneously, keeping your phone alive while you’re pretending to navigate by the stars. It’s waterproof, shockproof, and TSA-approved—rugged enough for the apocalypse, yet sophisticated enough for a first-class carry-on. Finally, a battery that’s tougher than your actual outdoor survival skills.
