We’ve all been there. You’re out and about. You look down at your iPhone, and the battery indicator is screaming. No sweat; you’ll just pop into your favorite spot and charge up. But wait! You forgot your charger at home! How are the honeys gonna hit you up on the two-way if the two-way is dead?

The Scosche flipSync, released today, solves all of our dead two-way (I’m seriously going to call it that from now on. Or at least the rest of this post.) problems, without bulking up your bag.

As if the gents up above don’t do a fine enough job explaining it: the flipSync sits on your keychain, and takes up about the same amount of space as a car remote. Pop it apart, and you’ve got a full-fledged iPhone (or microUSB, if you go that route) charger. It goes on sale this afternoon at Best Buy for $20 a pop. Expensive? A bit — but remember: you’re doing it for the honeys.

Two-way.
