iPhone 3G S + Mophie Juice Pack Air problems...

Yes my car charger doesnt work either. I dont know who makes it though

My Juice Pack is also producing errors, the full wording of which is:

*This accessory is not made to work with iPhone.*
+Charging is not supported with this accessory.+

Lots of discussions here about various charging accessories, mostly for cars, not working with the 3GS.

There is a device here http://www.scosche.com/products/productID/1667

which some have said fixed their problems. I can't vouch for it because all my chargers seem happy with my 3GS.

I would say, send it back if your within the 14 day period.

Yeah .. if it's new, return it. I assumed it was something you were already using with an earlier iPhone model.

I have the iPhone 3GS and the Mophie Juice Pack Air and have not had any problems.

Boy is this one bad advertisement? I get a pop up almost every 3 secs. Sounds does not work.

The problem only appears for me at the moment when the Juice Pack expires.
That's when the iPhone starts running on its own battery power.
That's when I get the charging error message.

Let's hope OS 3.1 fixes it

I bought a portable usb power supply 2 months ago like this one http://www.portablepowersupplies.co.uk/usbliionbatterypack.htm to use with my iphone 3g. It worked fine but then I got a 3gs and while I didn't get the unsupported message I did get intermittant charging problems with it. Sometimes it would just work and other times I had to plug and unplug it a few times to get it to charge correctly. An email to portablepowersupplies got a response that apple had changed the charging spec slightly for the 3gs and their product no longer supports the 3gs. When pushed further they said apple had altered the charging current or voltage slightly, I forget which. Its now on ebay.

The Mophie Juice Pack Air is a piece of Junk - Do Not Buy!!!

I purchased the Air a few days ago and it does not sync to the computer (get unknown USB device error constantly). The Air does not charge properly, according to Mophie both the Air and the iPhone are supposed to charge at the same time, but only the Air charges. Also, according the the Mophie web site and documentation, the Mophie Air is supposed to use its battery first and then when depleted switch to the iPhone. This does not happen at all, you have to switch the Air off and use the iPhone battery until it is depleted, then switch the Air on and charge the iPhone at which point the Air gets very hot and the Air battery barely lasts long enough to recharge the iPhone.

I called Mophie tech support and they said the supplied USB cable must be defective, and the printed documentation was not correct, the Air will work as I described above. This is basically FRAUD, Mophie advertises the specs knowing they are incorrect. Anyone interested in joining a class action suit please contact me.

I've been using a Juicepack Air with my 3GS for a few months now with no problems, knock on wood. However..........

The Juicepack as it gets to it's depletion point loses voltage. The iPhone detects this and reads the Juicepack as not compatible. This is normal. All you need to do is charge your Juicepack.

I think it might be best to sync on a POWERED USB connection. I have noticed a few syncing problems as well but only when the Juicepack is dead and attempting to sync on an unpowered port.
