Also the circuitry that is built in this NewTrent IPhone battery case is much more superior. Which ensures proper charging and discharging.

If lithium batteries do not discharge and or charge correctly then you can end up with a serious fire. Just google lithium battery fire or lipo battery fire and you will see. HP just had to recall 70,000 lithium batteries due to fire risk.

This is these guys specialty. They have their own manufacturing and lab testing facility here in the states. They know batteries for sure.

This case beats the mophie (80.00 at best buy)because it does not interfere with data/call reception like the mophie has been reviewed to do and the NewTrent IPhone battery case has a better non slip surface on it so it won’t slip out of your hand. Their customer service is also A+. You will not regret your purchase.

This is what is shares after buying New Trent IMP130 with Extended Rechargeable Battery Juice Case Air for IPHONE 3G and 3Gs

As any I-phone user knows that the battery life is terrible. I have seen several battery cases available for the I-phone and I decided it was time to get one. I looked at what was offered and found this product on Amazon. It’s about half the price of the competition. Too good to be true? I read the reviews of this product and decided to give it a try. So I ordered it was delivered two days later. Inside the package there is the case, a micro USB cable and the instruction booklet. I charged the case first by connecting the provided USB cable to my laptop and it took a couple of hours for it to charge.

There are three blue status LEDs, a momentary switch and a white LED next to the camera lens on the back side of the case. When the case is charging the blue lights form a bar graph level indicator. The light closest to the switch is the 0n 33% level indicator and the others will light up as it charges. When complete, all three light will be constantly light. The fit to the phone is good and the black plastic has a slight rubbery no slip feel to it. There is a 30 pin Apple connector on the bottom inside which mates to the phone. Inserting and removal of the phone from the case is simple.

There is an on / off switch on the bottom next to the micro USB connector. When its in the off position, the the battery inside the case is disconnected from the phone. Normal operation is with it in the on position.

More about the the momentary switch. If pressed momentarily, the blue battery level lights indicate the battery level. If pressed for two seconds the white LED turns on. And the same to turn it off.

I-tunes sync can be performed through the provided USB cable. (no case removal needed)

During discharge the external battery is used first and then the phones battery. When charging, leave the power switch on and the phones battery will charge first and then the case will charge after wards.

I love this case because the external battery will run my phone all day and I usually never discharge any of my phones battery. That saves wear and tear on the phone battery. And its a lot easier to replace a case than replacing the phones battery! The white LED next to the camera lens is great for using as a fill light for closeup photography and for using those bar code scanning applications.

The only negative that I can think of is if you use you phone with a powered speaker that uses the 30 pin Apple connector, then you must remove the phone from the case. As do most after market cases.

So if you want to double the battery time for a great price, look no further!
