Is not enough for Z100 Crocodile

The nameplate of the charging cable specifies the output with 5.5V / 700mA. If that had been read in the article description, I would not have ordered because the Z100 requires at least 1A (recommended often 2A).

Accordingly, the Navi loads only as long as it is made. When the battery is not already full and it is turned on, breaking the tension a at the latest when the Navi GPS receiver enabled.
With fully charged batteries, the device seems to run a while, if you connect directly to the Navi, not the cradle (at the Cradle on a switching transistor with insufficient supply from). This will only well until the battery is too weak, then turn the Navi due to low battery condition from rigorously.

Because of the low purchase price, the cost of the claim with return postage etc. is not worth. So tip the seller.
Actually, as in the description of the performance of the device is missing - 1 point
Since the Z100 is not listed in the description, for fairness - 2 points
