Packing
Goods was neat and stable packaged in a folding carton. Contents were the power supply unit, an attachable battery adapter and two batteries, a car charger and a user manual.
Commissioning
I have bought myself the batteries for my Lumix GH4. The battery adapter is plugged into the AC adapter. Only then can you insert the battery for charging. If you load a battery, the operating status LED lights up red. If the battery is finished charging it will turn green. So it must be. In addition to charging a battery, you can also charge other devices via USB and mini USB.
I have my iPhone, iPad, and my Garmin Montana with this PSU charged what was working fine. Since I only use this power supply with traveling.
The batteries are unhesitatingly recognized by the camera, including the battery indicator on the camera screen.
So far, the batteries do a good job and I hope it stays that way. Since the purchase, I have the battery charged about three to four times.
Rating
The price-performance ratio is very good. The power supply is very versatile and has an overall high-quality impression. The batteries perform perfectly so far their service.
I give an unqualified recommendation to buy. *****
