Unsatisfactory performance

I have already tried several USB charger for my HTC HD2 in the car. The reason was the general decline in battery charge if navigation, Bluetooth and phone was used. With Battlog could be tracked, that hardly or not at all been recharged.

Unfortunately, this is true for the Hama Dual Piccolino also to! It was even the first time so that was not charged when the engine is not running. Here, the original USB connection cable of the HD2 was used.
So back to the supplier.

Fortunately, the 1A terminal of competing Kensington PowerBolt Duo works perfectly on HD2.
