The purpose of such a multi-port charger is the (simultaneous) charging of smartphones / tablets / Navis etc.
This comes with an attachable power cord of good 150cm length and a Quick Start Guide in English in a cardboard box.
A micro-USB charging cable is not present, what I think is a pity given the intended use.
Not everyone has to load a suitable cable is available to its smartphones or tablets, especially if the original device has a power plug is firmly connected to the charger cable.
The charger is 7.5cm wide, 2.5cm high and 9cm deep and slightly larger than a cigarette box.
The surface is made of white plastic on the sides, the top is gray-matt.
The weight without the power cord is approximately 134 grams, which makes the device well suited for travel.
The charging adapter is me perfect on the desk. The four rubber feet on the bottom act here very non-slip. A useful detail!
On the top there are 3 USB charging ports and an on / off switch.
A small blue LED below the on / off button signals the operating very discreetly.
The switch is actually unnecessary, because an appreciable standby power consumption I could not find my Brennenstuhl meter.
This is somewhere below 0.1 watts, regardless of the position of the switch. Very good!
The actual charging is completely unspectacular.
The / The respective (s) connect charging cable and then as usual charging.
The top two USB ports provide this 1A charging current, the lower 2.1A.
A special marking this "power ports" but lacks what I think is a pity.
Apparently, the charger also features an intelligent charging electronics.
My S3 Mini, a grade 3 and S5 it could not be unloaded at the port with 2.1A, but already (coming from home with 2A clear).
At the 1A ports I could load all previously connected devices without any problems, even though in some cases significantly longer than the original charger. This was especially noticeable in my grade 3 and Tab S 10.5. At the 1A port loading took almost twice as long as on the 2.1A port.
So please better use this port to power hungry devices.
In operation the way I could neither noise nor a special heat generation even notice conspicuous odors.
A special feature of this charging adapter is its holding device for a smart phone or tablet.
In front of the depression can be the particular device are the shop off easily what my score 3 works even with the S-View case from Samsung. Very convenient.
In the overall analysis, I can recommend this charger almost 100%.
Only the poorly marked ports and the lack of intelligence of the charging electronics on strong Port detract from the excellent image somewhat.
For the price-performance ratio is relative to many competitors very well and the power consumption in off / standby mode almost perfectly low.
I hope this review could assist you in your purchase decision ....
