This small charger (in white) is for me, who am become familiar with the Li-ion batteries of the type 18650 to use quite outstanding. The unit is powered by two of these Li-ion batteries 18650 and can be used as a small spare flashlight. Both my mobile phone Samsung GT E2230 (I'm still a bit "old-fashioned") and the Samsung smartphone my wife can be with this device very easily load and will actually be almost full, as long as you two Samsung cell called ICR 18650- 26F employs, so two cells, each with 2600mAh. Included is a harness with USB plug and a number of different connectors. In addition, a charging cable with USB2 connector and mini USB connector lies. Amazing is the electronic circuitry in the device. It switches to the full-load the phones off automatically. However, exercise is need of opening of the closure cap, which one should go to work a little cautious. Overall, the device is an amazing development and for the price well below 10 acceptable. I ordered for us at amazon two sets to two batteries for about 9 and, if the batteries are exhausted after charging, replace them with two freshly charged and the device is ready for use again. A Power Bank 12000mAh of about which we also use and containing the same battery type, must be charged 10 hours after emptying of permanently installed batteries for now. This device may, however, depending on on how much battery you have, "incessantly" for charging mobile phones and small tablets (eg Intenso 814 8Zoll) are used. A development of technically highly meaningful and purposeful "handbag and pocket device". Edgar Redlich, Großholbach
