Okay, pay attention to these descriptors: waterproof. Compact. Dustproof. Mobile. Military-grade. What makes a charger military grade? Not sure, but it beats any other charger we’ve seen. The Poseidon portable charger ($89, fully funded on kickstarter) holds 8,000 mAh of power, allowing you to charge phones, cameras, laptops, GPS, and other fun stuff multiple times. Oh, and there are two USB outputs, so go ahead and charge two things at once.
