Product Description

Amazon.com Product Description

Use one less power outlet with this handy solution from Griffin, which allows you to charge two MP3 players or other USB devices at the same time. Charges Sansa, Creative, Zune, Samsung, iPod, iPhone and most other MP3 players and devices that charge via USB.

For MP3 players and other devices that get their power through USB, just plug in your device's USB cable, and charge from almost any 100V - 240V AC outlet. Each charging port on the PowerBlock Dual has a standard USB output of 5V at a rate of 500mA. It'll charge your devices just as quickly whether one or two are plugged in.

The unit has an LED that glows green when it's getting power, so you know it's ready to charge. When not in use, the PowerBlock's non-polarized blades fold flat for storage or transport.

5.0 out of 5 stars Look here for the specifications, February 28, 2010

This review is from: Griffin PowerBlock Dual Universal Charger for MP3 Players and USB Devices (Black) (Electronics)

Like most folks here, I am very happy with this charger, happy that it costs half as much as an apple-branded ipod charger yet has two USB jacks instead of one.

Some folks here have found this charger doesn't put out enough power for particular devices. Before purchasing this charger, it's a good idea to compare the power requirements for your device with the power this charger puts out.

The charger puts out 5.2 volts, and 500mA per USB port.

The charger also includes over-voltage protection and short circuit protection.

For more tech specs, see p.4 of the manual:

4.0 out of 5 stars Works for iPod Touch 3G, January 9, 2010

Works as advertised for low-end devices. If your device charges _normally_ off of a computer's USB port (without a special driver), it should charge off of this. USB spec is up to 500mA per port (see wikipedia) so this product seems to be built to USB specs. However, newer and power hungry devices require more. In the case of the iPad (1st generation), it does charge off the computer, but very slowly. The iPad works best when using a 2100mA (2.1A) or greater charger.

(this only charged my motorola W376G tracfone when used with a special charge-only cable, which was included with the Belkin Dual USB and AC Wall Charger)

This thing DOES work with the ipod touch 2G,
which isn't true about all chargers.

But it doesn't charge my Motorola cell phone.

Go figure...
