The unit was hanging in free air space, not contained. It was flashing 2-3 minutes in the basement where it’s 65-68 degrees F. If I turn it off, allow it to cool, and turn it back on it immediately starts warming up.
Before the recent heat issue, not inside a container, with the unit paired, when charging it charges to 92-94%. I have a second unit that charges to 100%, does not get warm at all. Understanding that there is a load while it’s charging, the % indicator is not my concern -I have to charge this one more frequently than my other unit (son to dad direct messaging in the home, direct msgs).
I will email Nate, thanks for the support email address (neat mobile package).
I let the battery drain, when charging it’s at 4.59v/1.14a, 105.9-111.7 deg F just below the USB connector. I lose bluetooth pairing, it shuts down, etc.
I split the charging device across a USB2 mini-hub to lower the amperage into the units, two are charging at 4.44v/0.85 total between them (temp: 94-97 deg) with both units off.
Does GTM not regulate incoming amperage? I will email support to confirm, but letting units slow charge to see if they work afterwards.
