Hi all. New to the forum. Hope somebody can help me with my concern. (Perhaps an elementary question to most here) My wife inadvertently plugged her pump into a 220 v outlet. The adaptor (not the pump itself) was warm to the touch but there was no burnt plastic smell. Seems like the adapter was damaged since we tried using a transformer after mistakenly plugging it to the wrong outlet and the pump didn't power up. But it can also be powered using batteries and it works fine this way - the motor still works the way it should. I plan to get another adaptor with universal voltage but I'm worried that something internal is damaged and might have rendered the ac function useless. Could this be the case? Any chance that the only part damaged is the AC adapter? Thanks in advance.
