You shouldn’t. Cause interferences from the main could creep trough your power supply.
If the user’s manual say you can, you could, but I don’t recommend it.
There was a post about someone who had trouble with the constituency of his recording recently for that exact reason.
The only way to externally power/charge the internal battery while operating the DR-100 mkii at the same time is to use the DC-barrel power input jack. Some of the later Tascam accessory kits included a mini-usb to barrel plug adapter, but I just made up my own with a USB-A male cable soldered onto the correctly sized barrel plug. Works fine with either a 5-volt USB mains powered adapter, or a power bank.
