Napkin math: 7V/2280mAh = 16Wh or equivalent to 3.7V/4300mAh (USB power banks are always measured and marked in 3.7V and mAh as unit to produce largest comparable numbers)

I've always thought it was odd powerbanks didn't advertise in mWh. That's a bigger number and comparable regardless of voltage.

If you want napkin math then just multiply 2280 by two. It'll be faster and more accurate than converting to watt hours.
