The rain finally stopped and the grass dried out a little so I took the Promoto-MX out for aroma in the backyard.
This will be the first time I have run it with a full battery.
The stock battery took 9.5 hours to charge with the included Smart charger on a 12w wall wart.
Ordered a QC3 wall wart we'll see how that goes.
So far it isn't looking to bad it's been charging for about 1.5 hrs and it between 75-100%
