Nope. they can operate on USB only.

@maximilian. If you check my other posts you see that from time to time I process a lot of data. These activities kill a battery pack also during runtime. While USB power is more reliable.

Okay, it seems to work on some older models, but it doesn't work on my fx-CG50. With the batteries removed, and with the calculator plugged into a USB charger, the calculator turns on for a second when the 'ON' button is pressed (just the backlight with a blank screen apart from the 'busy' annunciator in the top right corner), and then turns itself off again.

I'd make a youtube video but I can't be arsed!
