Griffin PowerBlock Dual Universal Charger for MP3 Players and USB Devices (Black)

• Charge two USB devices at the same time from the same wall outlet
• Charges Sansa, Creative, Zune, Samsung, iPod, iPhone, and most other MP3 players and devices that charge via USB
• LED glows green to show PowerBlock is ready to charge
• Non-polarized blades fold flat for storage
• Works with AC outlets from 100V to 240V

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.

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...

So far this has been an excellent charger. For those who care, essentially no power is consumed when the charger is plugged in but not charging. I tested it against my amp meter: 0.000 amps when not charging but green light showing, and around 0.0650 amps when charging my iPod. So you can leave this plugged in and not worry about consuming power when idling.

My PowerBlock was used infrequently (once a month or so) and lasted just over a year. The plastic holding the metal prongs/plugs cracked and one of the metal plugs no longer stays in... Griffen indicated that they could not help as the product was outside the warranty period. I can understand that, but I expected more from a lightly used product.
