So i went to charge my 18650 battery's in the trust fire TR-001 charger now there's a strange humming noise. Should this be a concern? Its not gonna blow up on me? is it? Its very loud. I have had it now for about a month or so, I ordered the TW Torpedo kit, i'm hesitant to call them because there pretty rude on the phone when there's issues with there products and are not willing to help but are very quick to take my cash! I m gonna have to get a new charger or battery's?
