USB - we all use it every day.
USB allows to share all kind of data on a small USB-Stick, on every PC. Even big amounts of data can be carried on an USB Hard drive. And it' s a perfekt power soure for mobile devices eg. cellphones or MP3-Players.
But soon you'll spot the first problems. You just haven't enough USB-Ports to charge all your moblie devices. Hard drives need to much power for some PC's, most stereo systems and all USB-OTG(on the go) devises. It's Impossible to charge Ipods with a normal USB charger.
I was annoyed of all these problems, so I thought about a solution. I came out with this USB-stick-sized adapter. It should help you with all your USB power problems.
Mainly it has 4 functions:
1. Charge two USB-devices at a single port, while one is still connected to your PC/ other host.
2. Charge two USB-devices with an external power supply.
3. Take power from an external power supply to be able to run USB hard drives on OTG devices, stereo systems, ...
4. Charge your Ipod (I haven't on so I can't tell you if it works). This may even help to charge your moblie phone faster, but try it at your own risk.
