Compact, inexpensive, take with you (throw it in your carry-on) kind of power.
I bought this for the numerous times I'm out and about, not near a charger.
Turns out, this works pretty well! Bottom line, you'll get to 40% iPhone battery charge in 1 hour and 80% in 2 hours.

I did a few tests myself: first, drained my iphone 4 to zero. Next, I attached the Stitchway UltraPower 1900, fully charged, onto my iPhone 4. Using a stopwatch, I recorded the following:
15 mins = 11% iPhone charge
20 mins = 14%
31 mins = 22%
48 mins = 33%
59 mins = 40%
70 mins = 48%
95 mins = 65%
119 mins = 79%
125 mins = 79%
151 mins = 79%

I stopped timing after 151 minutes.
I suspect it takes much longer to get the remaining 20% of battery charge.
Enjoy!

Since I do so many things that eat my battery power (graphics games, gps navigation etc.), it's a good idea to have a back-up when I'm out and don't have access to a plug-in charger. This item will completely recharge my iPhone 4. My wife and I both have one.

When I received this, it showed a capacity of 3 stars. I charged it to full (in a couple of hours), and then tried it on my iPhone 4. After 2.5 hours, it charged from 14% to only 59%, and then the capacity ran out, and it stopped charging.

It's a female/male pass-through design. So, you can plug in your power source at the bottom (female), or plug the top into your iPhone/iPod unit (male). The top (male) connector has a removable cover.

Load:
I'm going to try charging it fully, because I've had other issues with the first cable that I used to charge this. Then, I will try charging again and see if a full charge puts the battery higher than the 59% of my first test. I will update my review when I get those results.

Design (broken connectors):
I've read some reviews and suspect people are breaking their connectors. Although there's a protective plastic piece for the "male" end of the charging unit, when it's plugged into an iPhone 4 and laying on a flat surface, the iPhone/charger doesn't sit flush. The bottom half of the iPhone is elevated 1/4 inch above the surface, and the charger is not level either. If you were to press the Home button, or otherwise work on the iPhone while it's plugged in, you would risk snapping that little connector. It seems solid enough if you're not doing anything. So, with some precaution, you could avoid this by either not using your device, or holding the sides of the unit while pressing on it.

Operation:
The 4 led lights identify the capacity. They seem to come on if you have it plugged into a power source (male or female), or when pressing the button on the unit itself. The "full" led at the bottom probably only comes on after the 4th capacity is lit up, and it has a full charge.

First, I bought two of these. I wanted to make sure I would have enough juice for the long plane trip, and subsequent layovers, to Afghanistan. I tested them out a few weeks before I departed and WOW! They worked perfect. I realized that I could have probably gone with just one, but I'm an over-kill, can never be too prepared kind of guy. A few nights later I was on the phone with my girlfriend and, for the ump-teenth time, we got disconnected because her iPhone battery died. Something every iPhone owner is plagued with LOL. Anyway, I immediately went back on Amazon and since I have Prime, her battery was there the next day for an extra four bucks. Definitely worth every cent, because until I deployed and ever since we have never been disconnected because of a dead battery. If it beeps at her, she plugs this in and we can talk for at least another 2 hours that I know of because we did it. Before I wrap this up, for the intended purpose of keeping my iPod charged for the duration of the 20 hour trip to Afghanistan, this should get 6 stars. Between the two backups I have, they charged an iPod Nano and two iPod touches and kept myself and two friends listening to music the entire way. Hope this helps with your decision.

Buy this and do not buy more expensive rechargers. This one does the job quite well and does over one full charge for an iPhone 3GS in about 30 minutes. It is very small and portable.

1. Very light weight

2. Small

3. High quality feeling(not cheap materials used)

4. Shake it to see the quality how well it was made. It looks pretty strong.

For the price. It is pretty good. Those of you whose batteries won't charge anymore, you guys got the bad ones.

Mine works really perfectly. I bought two.

I did a little test

Real outlet charge time vs. this back up charge time speed

The back up charging time was a little bit slower but not bad at all

iphone 4 with outlet charger went from 13% -> 28%
iphone 4 with back up charger went from 13% -> 23%

not bad at all. just keep this in ur car
dont' buy an expensive one. why waste your money? seriously
let's save some moeny.

since last year I've spent almost 1800 dollars on amazon.

I want to share good reviews to people so that they will know what good stuff they should buy and the seller should get the money because they made pretty good products.

Im writing this review for the people and the seller who made this.
