Tried to charge overnight using a 2.1A output battery pack with BatteryBar Pro installed and logging enabled.
Note: Logging appears to prevent entering sleep.
Plugged in the battery pack at 9:23 PM with 29.8% Battery.
I pressed the power button to put the system in standby.
The number after the percentage is charge rate in mw, a negative number indicates discharging by that amount.
I removed fields after that for formatting.

We see it switch from discharging to charging and throttle up to over 6000 mw (1.2A) charge rate.
It continued at that rate for a few minutes at 9:38:40 it throttled up to over 8000 mw (1.6A)
Keep in mind the system will use at least .2A in standby and charging is not 100% efficient, more like 80%. If we multiply 1.6 times 1.2 to account for 20% efficiency loss and add the .2A used by the system in standby the total power draw is estimated at 2.12A ( 1.6 * 1.2 + .2 ) or more.
It continued charging and peaked at 8550 mw (1.71A) charge rate.

After a few minutes it appears the battery pack is back online and charging at a little lower rate.~ 77xx mw and continues at that rate until 10:42 PM where it throttles back to 931 mw (0.186A).

But it's now discharging. Status shows Connected Discharging and that continues ...
as of now we are at 71.5% still connected discharging.
This is not going to recover unless I disconnect the battery and reconnect.
