For longer weekend trips or intense back-to-back days, a USB backup battery charger can mean the difference between thorough notes and a dead phone or tablet. We recommend the Satechi Energy Station 10000. It’s small and sleek, although not quite light enough for casual daily use at 7.4 ounces (roughly twice the weight of the iPhone 5). But its certainly powerful enough: With 10,000 mAh of power, it can provide enough juice to keep your batteries charged for two to three days of use. It has two USB ports, one geared towards smartphones and the other for more power-hungry equipment like iPads and some digital cameras. And when your battery charger needs its own recharging, it’s easy—the pack uses Micro USB.
