CNET Editors' Rating

The Good The PowerMat Dual 1850 Rechargeable Backup Battery has a simple, compact design. It can power two devices at once and it can deliver emergency juice when you're on the go.

The Bad The Backup Battery's 30-pin connecter doesn't have a secure fit and you can't charge non-Apple devices that lack a Micro-USB port. Though economical by itself, the Backup Battery is expensive when you add up the related accessories.

The Bottom Line Provided you can afford it and it's compatible with your gadgets, the PowerMat Dual 1850 Rechargeable Backup Battery is a fresh, efficient, and convenient way to charge multiple devices when at home and on the go.

7.7 Overall

If the concept of a wireless charger sounds too strange to believed, I don't blame you. We have, after all, been trained for years to chain our phone to an electrical outlet when it needs more juice. So is there any way that we could abandon wires completely?

The answer is, not quite. Though companies like PowerMat freely use the term "wireless" when describing products like its home and office charger, real wires are involved. You still must connect the charger to an electrical outlet and you'll need to plug a second wire into your phone. Between those two wires, however, it is a whole new world.

Design and features
That's certainly the case with PowerMat's newest product, the Dual 1850 Rechargeable Backup Battery. Designed for use with one of the company's existing charging "mats," the Backup Battery serves a dual purpose. It charges two devices simultaneously (thus replacing the company's Powercube Universal Receiver) and it can store energy for times when your phone needs an emergency jolt.

The Backup Battery has a simple design that makes me think of a shiny skipping stone. At 2.75 inches long on each side and 0.68 inch deep, it's small enough to fit in a jacket pocket and it weighs just half a pound. The smooth plastic skin feels just sturdy enough, though it's not a product that I'd feel comfortable banging around.

On one side is Apple's universal 30-pin connector for iPhones, iPads, and iPods. It's certainly convenient, though the fit isn't secure. If I touched my iPhone even slightly while it was charging, the connection would shake loose and charging would cease.

The Backup Battery also has a Micro-USB connector that's attached by a short cord. Thankfully, that makes it compatible with most non-Apple phones and tablets these days, but you'll be out of luck if your device has a different port (like Mini-USB). Similarly, while the Micro-USB connecter slides into a slot on the side of the battery, it doesn't fit quite as snugly as I'd like. On the battery's opposite end are a Micro-USB port (more on that later), a small power switch, and four green lights that show the Backup Battery's power level.

In my tests, the Backup Battery performed exactly as promised. I first placed it on a charging mat and used it to power both an iPhone 4 and an HTC HD7 simultaneously. Boosting both handsets took no longer than when using a wall charger while the Backup Battery powered up in the same amount of time.
