The charger is supplied with a mini-USB jack (not the better standardized Micro-USB connector). A cable USB A to Micro USB is so you can connect it to a PC for example. Also a USB AC adapter is included, which in my case this has no CE mark.
The processing of the ALG 200 L is good and the sculpture seems as if it could hold a couple of years. Only the (plastic) latching the safety flap appears vulnerable, but because it simply can be left open this door, I think that is critical.
The device is easy to operate, 2 LEDs indicate the charge status. With 500mA charge current, a typical 3.7 V battery is charged in 1-2 hours.
I should mention here that the charger a eineglegten battery discharges (!), If it itself is not receiving power. If being supplied from the PC so do not forget to get out the battery pack from the ALG 200 L when the PC is switched off.
Bottom line, a good universal charger, helpful if the visit has forgotten his Handyladegeraet if you want to drive with a light pack (without a bag of various chargers) in the holidays when a special charger have to be refused and replaced.
Disturbing the missing CE mark on the power supply unit (security risk!), The fact that the device discharges a battery inserted without care, as well as the mini-USB input jack are (should be better microUSB).
Since I could not find anything better at the moment, I would ALG 200 L buy again.
