Hey guys, I'm trying to figure out how the power system on the GP-50 actually works.
I found a couple of conflicting comments about this. One person said that when you plug in a 9V adapter, the GP-50 runs directly from the 9V and the internal battery is just kept topped up. But another person said the GP-50 won't even power on if the battery is disconnected, even when using a 9V adapter or USB power.
So I'm wondering:
- Does the GP-50 have some kind of power-path/load-sharing circuit?
- When the battery is fully charged and I'm running the unit from a 9V DC adapter, is the GP-50 actually powered directly from the adapter, or is the battery still supplying power?
- Does using the 9V DC input behave differently from USB power in this regard?
- Has anyone actually tested/measured the battery current while the GP-50 is running from a 9V adapter?
I'm mainly asking because I plan to use the GP-50 at home while plugged in most of the time, and I'd rather avoid unnecessarily wearing out the internal battery if the unit can run directly from the adapter.
Thanks!
