The PowerTrip charger ($109) is a new and different backup battery for those who know the heartbreak of Dead Battery Syndrome. It's barely dinnertime, and your iPhone, Android phone or tablet is giving you the "10 percent remaining" sign.
There are plenty of backup battery gizmos available, of course, but this one is interesting because you can charge it from three different sources: a wall outlet, a computer's USB jack or — get this — the sun. Yes, there's a solar panel on the back for topping off the charge.
It stores enough juice to recharge an iPad once or a smartphone four times. So it's a single replacement charger for multiple gadgets and it's a backup battery. But it's also a flash drive, with four, eight or 16 gigabytes of storage for use with your laptop or whatever.
You can charge any device that would normally plug into a computer's USB jack, because the PowerTrip has a USB jack.
