TrustFire Charger

i noticed my Trustfire charger was making a humming sound when charging my powerizer batts and wanted to know if that was normal. i didn't notice any noises previously with the unit so once it made humming noise i unplugged the unit. TIA

Mine does the same thing y3hman, not sure if it's a problem though.

thanks Tracy, i'll put them on charge later and see what happens.

Yes, I never leave it unattended.

Mine does it as well, it's not a problem with your charger It's fairly common.

they are a switching power supply charger , some humm like that some dont .

should not be a problem , if it gets worse you might want to replace it

Mine also hums/buzzes and yes I keep it watched while charging. Got a new one coming from ebay though, four slots!

Mine plays the Star Spangled Banner. Is that normal? Actually I don't use mine too often. I have one I built that charges everything I got. ecig, Kindle, Phone, etc.
