Never get caught with a dead phone again! Plug this little powerhouse straight into any iPhone (up to iPhone 4/4S) or iPod Touch, and get juiced up in a flash. We plugged a Tech Candy battery extender into an actual (old, pitifully worn) iPhone 4, let it sit, and stood by, amazed. What did it do, you ask? Well, it took our phone:

Of course, results always vary from gadget to gadget, but the above are actuals in our tests. We even wrote the stats down on a piece of paper to prove it.

How does it work? Well, you charge your It's Bonus Time Battery Extender, and toss it in your backpack, briefcase, or bag. You don't need any extra cords or pesky connectors—just charge it with the same USB cord you use to charge your iPhone. Your battery extender will be ready to assist in your darkest hour of freak-out power need, holding a charge for months at a time. LED lights indicate remaining power, so you always know how much juice is left. When you need it (does that one guy at the airport really need to hog the only two outlets at your gate with his multiple gadgets?) just plug this lifesaver into your iPhone or iPod, and watch the life get breathed back into it. Then, get on the plane calmly. No need to shoot him the dirty looks.

You can even use your phone while the battery extender does its work. Bonus.

If you're a gadget geek and care at all, this tech necessory (get it?) touts 1800mAH capacity with a 5V input/output lithium ion battery. It's CE, FCC, and RoHS certified.
