Customer Review

Addendum 19.6: 2014:
Now have a replacement device, contact the manufacturer, since Amazon introduced cross and make any exchange but only offered a refund.
The replacement came in the known package. But seems to be a return or a Refurb device. The packing was unsealed and the inner cardboard shape was already strained and torn. But no matter. So plugged device and measured again. Maximum output current is still at 1:35 to 1:45. Only the USB5 "Android" labeled port only delivers max 1:03. (Indicated at 1A). Also this device. Device does not reach its specifications. Therefore bleibts for evaluation. But only because of the good (manufacturer) support.

Addendum 06.02.2014:
Have gestet after a long time again today the charger. And the values ​​have become even worse. Some ports have even no measurable output.
Possibly my device is even broken. I will seek a replacement and will report again.

Origin review:
Times have few measurements made to test whether the charger can deliver the promised performance. Focus on the 2.1A ports, because I wanted to replace a 2A power supply.

Was measured the charge of an Asus Transformer Book a short pure USB charging cable (not including data lines).
Voltage and amperage were determined using a measuring device between the charger and charging cable. Power consumption with a gauge between the charger and wall outlet.

The original power supply 2A / 5V supplies 1.88A at 5.2V and 11 Watt power consumption.

The "EasyAcc® 25 Watts 5V / 5A Wall Charger 5-Port USB Adapter Mulitport" provides:

First round
USB1 4.89V, 1.45A, 13W
USB2 4.92V, 1.51a, 15W
USB3 4.88V, 1,44A, 13W
USB4 4.90V, 1.51a, 13W
USB5 4.88V, 1.45A, 13W

Second round
USB1 4.86V, 1.44A, 13W
USB2 4.85V, 1.37A, 13W
USB3 4.84V, 1,36A, 15W
USB4 4.88V, 1.47a, 13W
USB5 4.86V, 1.44A, 13W

Well. It can here and have since given measurement inaccuracies. But what the measurements show:
-The Voltage should have the USB ports at all under 5V (though still within the tolerance 4.65 V-5.25 V, but lower voltage = lower power (P = U * I))
-The Specified amperage of ports appear to be totally irrelevant. Each port delivers about the same amount of amps.
-Only None delivers the promised maximum 2.1A
-were The values ​​on the second pass even worse (by heat development?)

The unit itself was delivered well packaged in simple cardboard. Content only charger and Euro power cord)

We recommend the device for people who want to charge many devices at once. But for this, depending on the unit for a long loading times must be taken into account. Tablets / Convertibles will probably load faster with the Originalladerät. In smartphones, no difference should be, because they are usually so anyway delivered only with chargers up to 1A, 1.2A.
