    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.

    You arrived unharmed. Long delivery time (3 months, 90 days ).The battery is not charged, the 12.6-volt charger can't be charged, the charge won't start in 8 hours. I hope the product isn't faulty. After charging, I can test its true capacity.
