We hooked up with the folks from BTI recently in Las Vegas to take a quick look at their GoStick II portable battery. This is one of those "need-it-right-this-second" solutions that'll give you an extra charge in a pinch via microUSB. The GoStick II has a 2,600 mAh capacity, so you'll only get about one extra go with this thing.
The GoStick II is nicely designed. It's about as big as a roll of quarters and finished with a soft-touch coating. The rounded triangle design fits nicely in your hand, which is a plus when you're using the included LED flashlight (long a favorite feature for me when it comes to portable batteries.) The five-stage charge indicator is easily visible but not harsh, and it lights up after you hit the button for 1 second. A 3-second hold lights up the LED flashlight.
The 5V/1.0A input and 5V/1.2A output are on the butt of the GoStick II.
The GoStick II is available now for $29 if you want to give it a go. We've got more pics after the break.
