I’ve been on the road a lot lately, and much as I like my Overdrive hotspot, its battery life is limited. So I decided to buy the ZAGGsparq 2.0, which acts as a backup battery charger for USB devices.

It features a lithium-polymer battery and can output 2,000mA at 5V, with a capacity of 6,000 mAh. The manufacturer claims that the ZAGGsparq can charge an iPhone four times on one AC charge. I don’t have an iPhone to test this claim, but I did get good results when charging the Overdrive hotspot and an iPod touch.

Physically, the ZAGGsparq is a square with rounded corners. It looks a lot like the charger from a MacBook Pro with a fold-out AC plug, and it is just slightly larger, at 3.5 inches square and 1 inch thick, weighing just over 6 ounces. The form factor fits well into a crowded power strip. As a bonus, the version I got came with an adapter for European plugs, although I’m not sure if that is standard equipment.

The ZAGGsparq has two USB ports. The top one is “optimized for smartphones and other devices that are capable of taking an optimized charge, including Apple’s iPhone, iPad [with a mini-USB adapter, not included] and iPod family of products.” The bottom port is standard USB. Both can be used simultaneously, although the manufacturer warns that both ports may not work when charging power-hungry devices like the iPad.

The device I got came about half charged, although I followed the instructions and let the initial charge run for a full nine hours. Subsequent charges have been much faster, at around two hours.

The device retails for $99.99.

Have a ZAGGsparq 2.0 or a similar device? Let us know what you think of it in the comments.

      I haven’t used it long enough yet to know how long it keeps a charge when not plugged in. So far, I’ve gotten at least two days from it, but of course, I was using it to recharge other devices during that time.
