I have an ION Tailgater which doesn't seem to be charging. The unit power doesn't have to be on whilst charging, but approximately five seconds after plugging in to charge, the charge light goes out, and it doesn't charge up. Any ideas

The manual is here

Hi Martha, had a bit of a look around and noticed a few mentions of charging problems including the following - 'One of these units was apparently dead on arrival and on further investigation, it worked off mains but not from battery. The battery comes out from a flap underneath the unit, and on testing with a multimeter, it was under voltage, so must have been old stock. Despite 2 days of charging, no life, so I ordered a replacement battery (RITAR RT1250 or equivalent 12v battery) and it works fine. I also have a proper battery charger rather than use this unit's own charger, which charges the battery rapidly, but I think at the cost of battery lifespan. Given that I use this unit infrequently, this is fine, otherwise use the internal charger as normal. With the new battery, I've never managed to run out of battery.. it will keep going all day on a single charge.

The manual does state that if you don't charge the unit at least every 6 months, it may not charge.'

I know it's not exactly a resolution but hope it helps!

Reinstall windows, or Factory reset...

Yo. This same thing happened to me. It sounds rudimentary, but I just superglued toothpicks onto the broken ends (obviously being sure not to get glue on the jack itself) and after waiting for them to dry, I just yanked them out by the toothpick. Worked like a charm. Good luck!

My tailgater is from the US, and I live in NZ. I changed the voltage to NZ and while the unit did work straight out of the box, after a month of me not using it, it now no longer has any volume. I have tried all the knobs but thats as far as my knowledge goes! Does anyone have any solutions I can try? thanks!

Very Easy!!! i just replaced mine yesterday, In the bottom of the tailgater there is a cover plate with 4 screws. Unscrew them and pull battery out, unplug the positive and negative cables attached to battery. Take Battery to an Electronic Store and ask for replacement battery. These batteries are also used in back up home alarm systems so they're pretty easy to find. i found mine at radioshack. Now to install, easier!!! plug in power and ground cables to battery, slip battey back into pocket screw back on plate, and charge for good 4-6hrs. and voila!!! you'll be bumpin in no time!!!!

You should have no problems.
I live in Australia, with 240 VAC, and we see this type of thing a lot.
Put the cap back on once you have switched it.
I have seen a computer power supply that was accidentally switched back to 120 as the switch had no cover.

Cambiaste tu bateria? yo tengo el mismo problema

When it is brand new only. If charged overnight and still does not last take back to purchase place and have them test battery..then make them replace it if it is bad...:)
