For these devices, the capacity is given in mAh at a voltage of the basic cells of 3.7 V - then a DC/DC converter is used.  It is the same as a USB powerbank.  The capacity in mAh at 12V is less than a third.  It would be better to state the capacity in Wh, then this capacity would be the same at 3.7V and at 12V (excluding DC/DC conversion losses).  The capacity expressed in this way is not only for this source, it is also used for larger backup sources consisting of 3.7V Lithium cells.

Használhatatlan!!!! Púposan érkezett, nem lehet feltölteni, 24 órás töltés után, már egy 30mA-es izzót tud is működtetni! Szemétre való!!! Ez átverés!!
