Ted, I would recommend just buying a back up cell phone battery or two.You can get them real cheap on Amazon and although they may be "knock-offs" they have worked just fine for me. They are much smaller and easier to carry around than a charger and power supply and or USB cable and spare AA batteries.I had since upgraded to a Motorola Droid X and this Tekkeon is not a good charger for that phone.

We have a Samsung battery pack with 9000mah. I would recommend at least this. Or a jackery with 12,000mah

Based on mophies claim: http://www.mophie.com/shop/juice-pack-pro-iphone-4s-4 The battery is a 2500 mah. I do know I can use the phone all day and well into the evening for voice and data. I put it on charge overnight and it's ready for another days use.

I use the energizer lithium AA. They seem to do a great job. Not sure about external packs.

I alternate between the ibattz battery that comes with it and 2 EC Technology i9300 2300mah batteries that work great. This case is awesome if you buy the extra batteries and wall charger (find on Amazon for around $25 as a set). Never have to be tethered to the wall again.

The LG power mat does NOT come with any charging cases, so you will need one for an iPhone 4. It is the best charging device I have used, and I have four different brands!

You can find them here on Amazon. The best ones I've found so far are the Nitecore 18650 NL186 2600mAh. Probably the best deal right now is the Nitecore Sysmax Intellicharge i4 version 2 Four Bays universal home/car battery charger, Four Nitecore 18650 NL186 2600mAh rechargeable batteries with Smith & Wesson Carabeamer LED Clip Light bundle.

Yes this one worked perfectly for my iPhone 4 At&t; GSM it should work just as fine on a CDMA (Sprint/Verizon) iPhone 4 but I will double check so let me know what iPhone u have this is not for a 4S

I'm not sure I understand the question. The pack never drains you iPhone. With the auxillary battery pack it does a GREAT job of keeping the iPhone charged when using this as a bike computer. The only time it would drain is if you did actually use the exercise tracking app and did not have some kind of auxilliary battery, this would suck the phone dry very quickly. If you just place it in the case, don't run any apps and ride around, it would be no different than carrying the phone in your pocket.

Mophie is another version of a large battery. Hyperion has worked quite well. However you may need a larger case for the greater depth (deeper back cover) of the Hyperion.

Hi Laurie, I was very disappointed with this replacement kit because is was a very poor fit for my AT&T; iPhone. The sceen continued to go white whenever the battery died and needed to be charged up. In order to get the phone screen to clear up, I had to hold the off button and function button at the bottom center of the phone. I just replaced my iPhone with and HTC Desire because my iPhone stop working for about a week and I couldn't get it to come on at all. I would not recommend you buy this replacement kit.

Hey Chuck, I bought these batteries about two months ago and they are awesome. I have a two year old EVO 4G and I still like it better then any other phone. The old batteries died and I almost traded in the phone. First I got cheap $2.00 batteries that claimed they were long lasting. The were bad and stopped working well within a couple days. Then I decided to get these batteries. My phones charge can last up to 3 days now. I have nothing to gain from this response, only good Karma if the batteries you get work as good as mine.

The battery I have is the Power Pack Slim 4000 which appeared to me to be a newer version of the P4000. It is compatible with my Moto X and does only one full charge in 3 - 4 hours.
