Red light.

[Siraj]

Hello everyone 

I've had this 4 in 1 jump starter for more than 6 months. About a month back the red light near the USB port went but has failed to go off. This drains the battery constantly. Even when I push the button above the port it gets back on as soon as I let go of the button.

The switch has probably failed. If the battery is still under warranty then the retailer might replace the battery. If not, then a new latching push on/off switch suitably rated (volts/amps) can replace the faulty switch if the old one can be removed.
