It’s a charger. For the original WOW Mop. You plug the small end into the mop and the big end into the wall and it charges the mop. That’s it. But while we have you here, we’d just like to compliment your fine taste in cleaning appliances...

Output Voltage:12.6

Please note: Not for use with Nellie's WOW TOO. Refer to listing photos to ensure you are purchasing the correct charger for your WOW Mop.
