Wow, talk about great customer service. I heard directly from the CEO in Netherlands where the 3G Juice company is based. He has offered me another 3G Juice product I inquired about, 1800 mAh, which is just one piece and no cables required. He will give it to me for free and also offered to let me keep the Major Mojo for free. I told him I had already shipped it back to Amazon, however. I was very impressed with such customer service which is quite rare these days. If you want great customer service this is the product I would recommend.

In another thread, posts have suggested this is similar to the complaints the 3G owners had last year. The phone would issue that warning but I seem to remember also that many said the phone would charge anyway. I've noticed this same concern appearing from the new 3GS owners and their charging cables and adapters. I have to do something soon. My iDay is approaching ....

YMMV

I am using the Duracell Powersource Mini:



I've been happy with it so far. It's a 3000 mAh unit; it looks like you can get a rebranded unit from Xantrex for $28 on Amazon:

The review of this device says it doesn't charge the iPhone.

"you need to extend the mini USB charging arm to connect with the Blackberry. Also, this does not charge the iPhone."

Iam thinking of buying the mophie juice air. But I like how slim the phone is already.

Well, I am very positive that this is the exact same unit as the Duracell. With that in mind, it did NOT work before with the stock Apple cable but now it does -- I think it may be related to the 3.0 upgrade. With the stock Apple cable (and with every aftermarket I have here), it DOES charge the 3G and 3GS. I did have to use a different charge cable (regulated voltage); perhaps Apple loosened up the voltage specs with 3.0?

I just got the incase power case today with my 3Gs, what I don't like is that it’s really slippery and it keeps sliding down when I try to type with two thumbs. I also think its messing with my signal as the bars will fluctuate up and down with it on, Ill have to see if that goes away. I have an external one I used for my V1 phone that I really liked and works well, and can recharge the phone several times but I would like to have one as part of the case and always attached. I just haven't been that impressed with the power slider.

The other one I have is a Lenmar power kit.

The new Air Pack is cool in it's design, but it is a little heavier than expected, costs around $80, and it is pretty hard to take off of your iPhone. The iPower doubles your battery life, has an external amplified speaker, costs half the price, and even works as a protective case for the iPhone. I own both and prefer the iPower. For those of you not familiar with it, I bought mine at http://www.iphonebatterypack.com. If anyone knows of one that's even better, please let me know.

I would love to see pictures of the iPhone in this case.

I'm totally over batteries hanging off of my iPhone:



While this is better than nothing, I'm looking for a battery charger in a case.

So, I'm limited to the Mophie Juice Air, Incase Power Slider and the iPower Air Pack, right?
