This little charger has 4 USB ports. It comes in a small package. In addition to the charger is a multi-lingual instructions, as well as a connection cable in the package.
To recharge all 4 USB ports can be used simultaneously. Is provided, the first two ports (5V / 1A) to use for Smarthphones. The third and fourth output is designed for tablets (5V / 2.1A). Basically, any device can be charged to each port, only then it may take a little longer, perhaps for certain devices.
Even if 4 devices can be charged simultaneously, charging goes very quickly. I notice no difference to the normal recharging via power grid.
The 4 USB ports are each about 1cm apart. Thus, for the ports all operate properly, because enough space in between. Furthermore, the connections are well made, they do not wobble, and are not too tight when you connect a charger plug or pulling out.
There is a blue warning light that stays lit when this Wall Charger depends on network. I personally check light is too bright. When it's dark, it illuminates a large radius. For me it would be inappropriate for the bedroom. It leads us to the fact that we always pull the plug, if we load a device.
Because the box is quite small and has a completely black casing, it is very unobtrusive.
Conclusion: If you want to bring some order into his cable chaos, to this small 4-fold Wall Charger is on. So you can easily load 4 devices at once and has to look no more empty socket. I am very pleased. This little charger RavPower is highly recommended.
