Solar Boost Bag

[adafruit2]

well it could be the thermistor is affecting the charge rate, or the battery is not in a state where its accepting more current. there's not that much going on in the lipoly charging chip

Hello for information, the battery was at 3.7V on the picture
battery and resistor bought from your site last month
what do you propose to fix this issue

[adafruit2]

i have no proposed fix, it is charging...it seems to be working. batteries dont always charge at the full rate

Hello,
Should I have to understand that the standard behavior of the SOLAR BOOST BAG is to get this amount of current?
To no get the internal battery fully charged after 12 hours is standard...
I do not check the amount of time needed to get the internal battery and the phone (plugged to the SOLAR BOOST BAG) both fully charged. But I guess it will be at least 24 hours (I'll make the trial if asked)
From my point of view the standard efficiency of the SOLAR BOOST BAG your selling is from far better than that, some thing goes wrong with the one I got.
Let me know your point may be I missed something.

taking a full day or more to charge a battery is not unusual. solar is not very efficient!

FYI:I was speeking about performance using a wall 220v/5v DC adapter

[adafruit2]

sure

[Barbiturix]

Yes

Hello
because it seems to be useful, I attached a 13 sec. timelapse sequence showing my phone charging during 25hours using My solar boost bag supplied by 220V/5V wall adapter.
You can see after 24 hours the boost bag was near to be fully charged, The phone is just 25% charged (see the picture of the gauge).
