External backup batteries are standard packing for gearhead travelers – there’s virtually no other way to keep your gadgets juiced up on the road. Which is why, if you’re going to pack extra juice, go big. The Anker Astro3 12000mAh features the highest available 4A capacity to charge up to three devices at once. An integrated, universal Smart Port identifies the device being charged and delivers the fastest possible charge. It’s capable of six to seven full charges for most smartphones, delivering more than 50 hours of talk time. That oughta prepare you for a few weeks in just about any corner of the world (… or the zombie apocalypse).
