Sick of portable battery packs that over-promise聽and under-deliver? We鈥檝e tested ones that have failed to hold the advertised capacity, stopped working if left uncharged for as little as two weeks, and a whole bunch that will die if they鈥檙e ever dropped or submerged. Not Dark Energy鈥檚 new Poseidon ($99). It鈥檚 overbuilt for outdoor adventure, promising you bulletproof (literally) power for your gadgets throughout extended trips.聽
About the size of an iPhone 6 Plus, the Poseidon鈥檚 10,000 mAh capacity can charge that phone fully nearly three times. And, with both one-amp and 2.4-amp USB ports, it鈥檚 capable of rapidly charging USB-C devices, too. In fact, it鈥檒l work with any device you can charge through a USB cable.聽
We鈥檝e carried the Poseidon everywhere from week-long backpacking trips听迟辞 ice fishing in sub-freezing temperatures听迟辞 simple airplane rides to Europe and back, and even took it here in Southern California. Often, we mounted it externally on our packs using the included carabineer for quick, easy access to power. There, it not only provided more than enough power to keep our phones, cameras, and radios running for up to a week, but it聽also survived rain, snow, and chaparral聽unscathed. It even doubles as a backup LED flashlight in an emergency.
Certified to the waterproof, dustproof IP68 standard, the Poseidon can survive听迟辞tal water submersion or a聽shot with a 12-gauge shotgun鈥攕omething Dark Energy tried during durability testing.聽
Need a charging cable that鈥檚 just as durable? Dark Energy sells a USB-to-micro-USB cable that鈥檚 . Similar to the ubiquitous survival bracelets, the synthetic rope protects the cable from abrasion during daily use聽and can be unwound to provide 20 feet of 550-pound capacity rope.聽
