I thought I could use the RavPower battery as a kind of UPS. Power the CHIP from the battery and
connect a USB powersupply to the battery at the same time.
However, it appears that this silly battery does not allow that! When I plugin the charger, it drops the
output voltage and my CHIP turns off.
I tried running the CHIP from only the (fully charged) battery, and it appears it can sustain it for only
about 6-7 hours (I kept a tail -f /tmp/messages open on an SSH session so it is not exact).
Now I would need to charge it again (with the receiver OFF) and then can do another 6-7 hour run.
How useful is that? I think it is imprtant for the operation of a receiver like this to be online for as
much time as possible, preferably 24h/day. So a “UPS-like” operation would be useful for those that
have unreliable power, but a charge/use/charge/use cycle is not.
The battery came with my kit, actually I was not careful during ordering and got the deluxe kit for $20
more, but I seriously question the usefulness of this battery!
Especially now that I have found that the CHIP can actually work off a directly connected bare LiPo cell.
Wouldn’t it be much better to provide a bare cell and a USB cable (and maybe a charger, but that
could be tricky due to national differences) with the deluxe kit instead of this RavPower battery?
