Customer Reviews

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!

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.
