Luv the lil’ thing!
Rating:4 out of 5 stars
I can’t really live without one or two of these puppies- I use my Iphone so much that even my car charger cant always keep up with me!

The only thing that could be better would be more oommphhh, more raw power (Energy/Time) and/or Energy by itself (Amps I believe). With heavy usage, I could probably use a couple of these.Like when I’m out and about all day long and using Google maps non-stop and Yelp! non-stop on my Iphone 3G. I really like it because the shape and size are perfect. So perfectly compact and convenient in fact- that I have recently mis-placed it! which makes me kind of aggravated….

To emphasize- for me- nice design and cost are always of the utmost importance and I find this pak very sweet on both accounts. Worth it to buy a couple I think…hope the other one shows up someday!

I hope I can help people get a good product for small monies…

Worthless, short life span!

It worked fine until it died shortly after purchase. Waste of money, especially when you buy the combo (charger). This has been reported multiple times elsewhere. I did not listen and I am paying the price.

Does the job (my detailed review)
Rating:5 out of 5 stars
Well, for sure this battery WILL NOT recharge your iPhone to a 100% if your main battery is drained, but I will give you a nice and useful charge, FOR SURE.

I have an iPhone 3GS 32GB and these are the two tests I’ve made so far:

Took the iPhone to a 20% of remaining battery and did:

1) Leave the iPhone alone (not making calls nor anything else), but with 3G and bluetooth activated, put the mini battery in and when it drained, the iPhone battery was at 70%

2) Leave the iPhone alone again, but this time with both 3G and bluetooth disabled. When the mini battery was dead, the iPhone battery got to 80%.

These are my 5 cents of my experience with this mini battery so far, I’m glad with it totally recommend it.

I will do more tests later and let you know. These tests will be of actually “using” the iPhone while the mini battery is plugged in.

Disappointing over time
Rating:2 out of 5 stars
This little battery pack just isn’t worth the trouble. It is certainly small, and maybe if you need just a little boost to your battery it might work for you, but I am getting no where near the stated time, or amount of charge. So from a auxiliary battery point of view, it doesn’t cut it. Secondly, because it’s a little heavy (certainly heavier than Apple engineers envisioned anything that hangs off the dock connector being) it really wiggles around, does not stay put, and on top of that also loosens up the dock connector itself.

died after 3 uses
Rating:1 out of 5 stars
This charger simply died only after 3 previous uses. I took it with me on the road last week after charging it fully. I noticed that it was not charging the iPhone at all when I tried. When I returned home, I found out that the charger itself no longer gets charged.

Little Battery Charger
Rating:5 out of 5 stars
I think this is a great small battery pack for the iPhone. Charges via USB with a mini USB part that goes into the battery pack (you can plug this into the wall if you have a USB charger to AC charger). Small and easy to travel with for those who are on the go. I also have a Casemate Fuel which charges similaly but is a battery and holster. The Casemate is lighter and works well but I got this as times I do not want to have a holster. With both, I would not have to charge the iPhone for a long day or two. Got this at BestBuy for $20, on sale. The Casemate Fuel cost me about $59 a year ago. Both are great, but I would have bought this only if it had been available when I bought the Casemate Fuel as it is smaller.

works great
Rating:5 out of 5 stars
I bought this charger couple days ago and I must say I love it. Let me first say that the main feature is the size – this charger is very small and requires no additional cables for charging the iPhone and thus is very portable. If you are somebody why needs to add additional battery power every day then don’t buy this, but if you are like me and you need extra power once a long while because u flying or staying in friend’s house overnight, then this is great product.

I was able to charge iPhone 3GS with 20% battery power left back to 80% in 1 hour and to 95% in less than 2 hours. If you turn the iPhone off (if u flying for example) and then start charging it, you might get even faster charging time.

There are few gotchas you should be aware of.

1. if you use a case with your iPhone, the charger might not work. I was lucky and the charger fits and works with mine, but it’s not really securely attached. I have to remove the case if I want really good grip. This is of course not an issue of the charger and I really don’t care that much simply because I don’t use this charger every single day.

2. The cable which charges the charger is USB-to-MINIUSB has issues – first it’s only charging cable and not datacable (no idea why) and thus you cannot use for other things (I hate to carry 20 different cables when I travel). The second I really don’t get why this cable exists in the first place. Why the charge cannot use existing iPhone charging cable instead or at least have an option to use either miniusb or iphone cables?

Keep it in my purse.

Wonderful gadget to recharge my iPhone.

Easier than carrying a recharger cord for times I am running low on charge
