Grade: 4 stars (out of five)
The scoop: DoubleUp dual USB charger for iPad, iPhone and iPod, about $40.
What is it? About the size of a hockey puck, the DoubleUp gives you two charging ports for USB devices (2.1-amp/10.5-watt) that can plug into a regular wall outlet. Small LEDs on the unit let you know when the mobile device is fully charged.
Why it's cool: Power outlet space is often at a premium in hotel rooms, so any device that can give you extra charging capabilities is appreciated. In the case of the DoubleUp, you can basically get three devices charged instead of two (or even four if you use two of these units in a regular two-outlet wall port). If you need to recharge an iPhone and an iPod (or iPad), this handy device makes it slightly easier. While the marketing says it's for the iOS world, you could certainly plug in another device via the USB cable (as long as the device supports that wattage/amperage). The unit is also small enough so you don't have to bring one of those big power-strip extenders.
Some caveats: No cables are provided, so you have to bring your own. But at least you don't have to bring along the power-prong brick.
