Hi all!
I have a rechargeable waterpik that isn't working. Upon further inspection when opened it seems that the 2.4V battery just isn't holding the charge. (An extremely common problem it seems from user reviews)
What i want to do is bypass this battery and use an old cell phone charger that i have at my disposal. Inside this unit there is a small DC motor(no rating)
that drives a gear that seems to push the water up to the tip. I've checked the load on the motor which draws almost 1A and coincidentally that is also the current being used on my old cell phone charger.
The only difference is the charger output is 5V. I honestly don't know much about motors in general but have read that alot of them will operate in the 2.2V to 5V range.
When removing the battery and plugging in the original Waterpik charger, the voltage coming in is 3.7V (3V output 100mA)with a diode directly across the motor(protection?)
Can i assume that 5v should be fine to operate this motor without any risk of
burning it out?
Thanks,
