Works great and handy packaging for both 2-A & 3-A rechargeable batteries. I do recommend this device.

if the batteries are in it and its plugged in to outlet and no lights come on its possibly deffective but batteries must be in it for any lights to come on

The red light should turn on. Perhaps you don't have it set well? That happened to me. It took some twisting and turning to get the light to come on. Check the phone. It should show the phone charging if it is working properly.

With the device you are using on AUX, do you also have it plugged into your cig lighter for charging? If you disconnect it from the charger, does it go away? If so you have a ground loop problem.

How can you tell if you have a dumb charger? Mine has one indicator light and nothing else, so if it's a timer it must only be internal.

Make sure your connection to the charger is locked tight. Push it again then check lights.

I would contact the seller to fix this. I recieved mine in working condition. My charger goes from green to red when charging.

If the LED doesn't turn on while you are charging it, then the unit itself might be defective. If it does, then try holding the power button for 60 seconds. If, again it doesn't turn on, then it is also a broken unit.

Red light comes on when charging. It doesn't sound like you have it plugged into a good power source if it died while plugged. I ran mine for 3 days plugged in then on a 7 hour drive in the car on battery. Try plugging the USB into another charger or make sure if you are using a computer that it's powering the USB port.

Suire you checked that the charger wasn't the problem. I would contact Sena and see about returning the bad unit.

Yes! I just went out to double check. First I plugged it in the wall. Then I plugged it into the cigarette lighter. The red light came on the element plugged in the wall, when I plugged into the cigarette lighter. You may have to wiggle it a bit in the cigarette lighter for the red light to come on. That's not the case for my car here, but I have another one where it's necessary to wiggle it a bit for the light to come on. Unless the light comes on, it's not charging. That would be my take on this.

Don't remember how long it took. But-I can tell you- the red light at the base of the plugged in charger must be on , when the radio is sitting in it. If the red light is not on, the base unit is not charging. I sometimes (not often) had to make sure the radio is leaning against the charging contacts in the charging unit until the red light went on. If it is not sitting in there properly, and the light will not go on, and it will not charge. One more thing--that red light is ALWAYS on when the radio is in the charging unit. Which is where the radio should always be unless you have it in the car with you or on a walk, etc. You might also want to wipe the contacts on the back of the radio and on the unit to be sure nothing is on there to prevent good contact between the radio and the charging unit.

After plugging your device in you need to press the button on the face of the charger. If that doesn't work it is probably defective

try replacing the USB cigarette adapter with a different one - sometimes, car USB adapters can be problematic.

usually when you charge it , it should have a blue / red light that pops up. if it doesnt, it can be broken or you didn't charge the charger yet (:

I agree with the previous response. If you know the outlet is good and its fully plugged in and you push the on button and nothing happens most likely the power supply in the unit is bad. Time to return it.....

Jumping on this one... similar problem... charger dropped but the RED wire came off of the 2/12/75 switch... can you comment on where THAT one goes? Thanks....

According to the written text on the charger it states Red Light Flashing - "Reverse Polarity or Battery Fault" So I'd double check whether you connected the leads wrong then get a battery tester to make sure an internal short does not exist. Hope this helps anyone reading this question.
