Unless you genuinely want to disconnect from the world, bringing a portable charger when you go off the grid is a must to keep your devices juiced up. But backup batteries run out of power quickly too, and when they give up while you're in the middle of your trip, sorry, you're doomed.
With the Universal Waterproof Solar Charger, you won't ever have to face that problem. It packs 5,000mAh of power to easily recharge your smartphone or any other gadget. Unlike most portable batteries, this one doesn't need to be tethered to a wall socket to regain energy. It soaks up power from the sun, so you would only have to leave it out once you deplete its charge. Yeah, solar power is unreal.
With two built-in USB ports, you can power up two devices all at the same time. Plus, it's waterproof and shockproof, which means it can weather through anything.
