Today’s public service announcement is to inform you that the Black & Decker Pivot Driver (Model 9078) uses a 5VAC ~200mA power supply with a typical 2.5mm barrel connector for charging. The 3.6VDC marking on the driver itself is the power requirements for the motor, the charging connector is unlabeled, and a decal on the unit simply directs that only power supply 90500898 be used. Now you know that 905 That is all.
(This sort of information is often terribly hard to find when needed, such as when the device needs a charge, the power supply is missing, and a suitable replacement can’t be found. Hopefully stuff like this will one day help someone.)
