Price: $20
Why It’s Green: These USB-powered rechargeables last for 500 charge cycles, so say goodbye to the 15 billion disposable alkaline batteries produced annually, and their toxic runoff.
Why Buy: Functions like your standard everyday AA battery. When empty, though, just pop the top to expose a USB connector, then connect to a laptop or other portable device to enjoy a quick refill.
Practical Applications: Powering in-flight movie marathons, mobile alarm clocks, and the odd automated German-to-English translator, so you need never again ask locals how to say, “Dude, where’s my bratwurst?“
