Good USB multi-outlet charger

It arrived well packed in a good box, also containing a power cable standard, and a user manual, according to the description (picture). Of course, you will provide the connection cable between each of your devices and charger.

The manual is in several languages, and the least we can say is if the quality of the book is OK, the French version is pretty rough: many spelling mistakes, and mistranslated phrases. Example: "Intelligent Technical iSmart can know the current need your device automatically". Also look at the photo of the underside of the original packaging ... Overall, we find it but it's an annoying thing.

The charger: quality is the appointment with a box with rounded corners, a non-slip rubberized, 6 USB ports, which hold well cables, voltage references and intensity readable with each shot and below the device (photo ). The power cord is long enough (1.20 m) so that you can not really describe the magazine "Wall".
The weight I have noted is 195 g without power cable and with 250 g (155 g indicated in the instructions)
Dimensions: 7 cm x 10 cm x 2.7 cm are not those of the manual. The volume is very close to my camera (Canon G12) (photo)

Point of view of the charging efficiency: I could not test or a different input voltage or 220V output 5V / 2.4A with no compatible device. My Asus Transformer tablet would not be satisfied with 5V; my GPS and all the family of phones are 1A. The power of the charger is indicated by a small green light. Pity there was not for each outlet.
The charge phones is fast, without heating or charger or appliances. After almost complete initial discharge (1% remaining), telephones (aged 2-3 years) are charged at 1% to the average minute is substantially the same as the original charger but better x5 the charger "no name" bought elsewhere. The GPS took charge more slowly. Probably differences batteries. Plugging 3 Phone + GPS at the same time has no discernible impact on the speed of load compared to a single phone charging.

Among the flaws: a whistling occurs after a few minutes of charge. This whistle is approaching those systems against rodents or devices "anti-youth". Additionally, when charging, there is interference with the FM station in the same room.

To conclude, I would say that after a few days to test the charger, it is useful if you have multiple devices that require either 5Vx1A either 5Vx2A, to load simultaneously. This frees the catch, save time and occupy less space. However, I think we have at least 4 devices for this to be valid because we must not overlook the fact that this charger is much larger than the current unit chargers. The overall quality seems to be at the rendezvous and small imperfections are not identified unacceptable to me.
