The Ansmann Powerline 4 per awaits with many charging functions. Also in the car USB devices can be charged with the supplied power outlet both AAA, AA and space. Of particular interest is the extensive control of loading, unloading and the current voltage and the charge currents used. And individually for each charging slot. A worthy successor to the indestructible predecessor (which I've professionally for 4 years in Eisatz). Bird - the reference!
