Having a dead phone sucks. It sucks even more when there’s no electricity nearby. That’s no problem with the Eton BoostTurbine 2000. Packing a 2000mA battery, it can easily charge up your cell phone and other USB gadgets. If you’ve already drained it, you can use a little extra elbow grease to manually charge it. 1 minute of hand crank charging can give you a 30 second phone call, or let you do some quick texting. Not a bad thing to take with you on long trips.
