Anyone else got problems when charging with external battery pack?

Hey everyone,

does anyone else have a 2. gen Anker Astro E5?

I started using one one month ago. It charges my FP1 up to about 70% without a problem. Afterwards, at about 80-85%, the charging constantly stops-restarts-stops-restarts, so that the red LED is blinking.

If I turn on the display (set to keep on while charging), this sometimes stops until 95-98%, and then the behaviour restarts until the battery is full.

When I use a generic USB cable (not the one coming with the external battery), the charging most of the time (around 4 out of 5 times) completely stops short above 70% battery capacity.

I wonder if this is FP-related, or the external battery is defective. The manufacturer, Anker, praises itself having developed an intelligent charging system, i.e. the battery is negotiating the energy to be delivered with the phone’s electronics.

I had this trouble from the start, and now contacted their service. They would replace it on warranty, but before doing so, I wanted to ask if anyone on the forum is using the same model and can tell if he/she has the same problem. I don’t want do produce more e-waste.

I also wonder if my phone’s battery could get damaged by the behaviour described. Any comments?

I haven’t been around much since, uh, August, I think. Hope to be more active again in the near future. But the future is an undiscovered country, so let’s see if this works out. :smile:

Never had any problems with a Waka Waka Power Light, so it’s not a hard FairPhone/external battery problem. It might be the combination of a FP1 with the Anker Astro E5 though. Or maybe even specifically with the one you have.

Sounds like the “intelligent” battery does not understand one of Fairphone’s core values, namely cooperation, instead of holding back information (energy)… :wink:

I have two different power packs which both work.

The only problem I ever had was when my battery started to bloat. Then it would sometimes not charge at all. However that was independent from the choice of power source.
