Practically, however, has shown that with the Astro E1 anchor the Lumia can not be fully charged. There are about 80% of the maximum load of the phone reached (starting with an empty phone battery). I have repeated several times to the battery to provide the charging process the chance to incorporate. That has not changed the result. Then I have to have the device might get caught returned hoping a runaway production. However, a second device was exactly the same results.
The battery should, according imprint type 19.42 Wh capacity have the charge after deducting losses not quite able to fill 13.3 Wh phone. However, since the losses have significantly more than 30% are do not appear very plausible. Perhaps the Lumia 1520 has also energetically very unfavorable charging circuit but so much worse than a IPhone6 ???
Except for the not quite ideal for me load capacity however, it is a great product, and therefore I kept it and would recommend it. Especially since the Lumia 1520 with 80% charge is playing throughout the day and therefore is a sufficient during daily emergency charge.
