To test performance we fully charged the Duracell 5 hour USB device, which took 5 hours from flat. We then connected the (completely flat) BlackBerry Phone to see if it would deliver a full charge again. We did the same with the iPod Classic, after recharging the Duracell 5 hour USB device. Finally we connected both devices and charged them both when they had flat batteries.

The Blackberry Phone was charged from flat to 100% charge without a problem, and the Duracell 5 hour charger indicated some capability left within.

The Duracell 5 hour charger was attached to a mains for several more hours until it read 3/3.

The Apple iPod Classic was also charged from flat to 100% with some charge left in the device.

We charged the Duracell 5 hour charger again to 3/3.

We ran both iPod and Blackberry phone to flat and attached both simultaneously. Charge time for both devices was a little longer with both attached, and the phone and iPod read a 2/3 charge before the Duracell device ran out of charge completely.
