Has changed my entire iPhone life. Instead of dead at 2PM, it is plug in this little guy(can't weigh more than a couple of ounces) and it is full usage until I am done for the night. Will probably buy another for those long flights I sometimes take. Stitchway UltraPower 1900 mAh (BLACK) Backup Battery Charger for iPhone 4,4G, 3GS, 3G ,iPod, iTouch-EXTERNAL, PORTABLE, RECHARGEABLE
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.
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!
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.
Bought two of this for my son and daughter who are always running out of batteries in either their iPhones or iPods. Both say its good, but it doesn't fit when they have the otter-shell in the iPhone, so they have to remove the shell to use it. It would be great if it came with an extension adapter that made it possible to connect it to the iPhone when it has a cover.
This is excellent! I just got it today and I decided to test it so I plugged it into my iPhone, and about an hour later it was fully charged! I am now charging the Battery for later use on the long ride home. I have both an iPod touch 2g and an iPhone 4g. It works great for both! I am completely satisfied.
I love being able to toss this in my bag and not worry about my phone dying at work when I'm unable to plug it in. Also when i went camping it was great since I charged it and the phone, which left menwith a nice backup. My daughter has used in on a long trip to recharge her iPod and it saved my sanity.
I just did a test today, I intetionally left my iphone4 run until only 3% battery life left, and then plug in this item which has been fully charged. In about 2.5 hours, this product ran out the power, and I check my iphone 4, it has been charged to 89%. Thus, this portable charger gives you roughtly 86% of your iphone 4 battery life. It cost me less than $8, thus I consider it as a good buy. BTW, this portable charger is about the half size of your iphone4.
I have been searching for a good, portable, reliable and compact charger for my iPhone 4. I use my iPhone a lot and there have been times I was away from a power source and needed some battery juice. This is common in my vacations and I was very pleased with my results. So far I have tried it once, and tried plugging this charger in two other iPhones to see if the dreaded "This device is not compatible with phone," or the likes of it, to come up and it never did. The phones recognized the charger with out a single glitch; the other two iPhones were a second iPhone 4 and a 3Gs. My test charge was from 37% battery to 89% after the charge on my iPhone. This was from a fully charged charger(4 lights), and after this charge of 52% to my iPhone it left the charger with two (2) lights. This means that it still had 50% of more battery left.
I will continue testing this charger, but so far the first result speaks for itself. I have purchased other chargers for my iPhone, surprisingly at double or triple the cost of this one, only to find myself very disappointed and left with a product that is unreliable and with no way of returning it to recuperate the money I wasted on them. Also, one last note, I bought it from the Amazon seller BestDealUSA at a whopping total cost of $7.47 ($6.97 charger + $0.50 shipping). I have bought a second charger from this seller and I recommend this product to anyone, like myself, who has the need of additional portable power for the iPhone when you are out and about.
Update as of 8/01/11: I have purchased three more for gifts from this vendor. I have used my charger at least once a week and I can charge it and leave it alone for over one month with out having to charge it again. I am a highly satisfied user and would recommend it to anyone looking for a cheap, small and reliable charger for an iPhone. - Iphone Backup Battery - Itouch Battery - Iphone 3g Battery Pack - External Battery Packs'
