The "inaccurate" display by the 5 bars: not particularly bother me. if you know, at 5 "mark" (the word POWER POND serves with its 10 characters as an indicator) is final.
The feature, which was a purchase criterion, unfortunately does not. The charging of this battery and a hanging thereon consumer.
Example: the Power Pond is loaded with exactly 1 amp, the pendent Bluetooth headset that draws 0.35 amps is not loaded.
Furthermore, the charging process does not start "automatically when you press the green button". Because you have to push a button, so that's not automatic.
For additional confusion contributes that if one has tampered with the device beforehand during a period (charge status checked what else loaded or this battery it is still awake self. Then you have to press the green button.
And what a plug / charger I under the '2A (mpere) "port stecke- I do not know after a few months still.
Too bad.
Conclusion: powerhouse, invites reliable and fast, and 2 devices at once, simultaneous charging of this battery and one hanging thereon consumer not possible.
Good device with misleading and partly incorrect information on the operation.
Still recommended if you are willing to get to know it.
