 This soap bar sized device does exactly what it promises Mar 27, 2010
By ITM
The Satechi iCell does exactly what claims: Completely charge a mostly or entirely depleted iPhone 3GS 3-4 times before it itself needs to be recharged.
The unit is very roughly the size of a long, thick and narrow bar of soap. You wouldn't want to carry it in your pocket but it can be dropped into a briefcase, equipment bag or large purse with no problems.
The device is simplicity itself: You charge your iPhone just as you normally would, but end of the cable that normally goes into a computer USB plugs instead into the iCell. The iCell's own power level is clearly displayed by five bright green LEDs.
One thing to be aware of: You can't charge the iCell just by plugging it into the wall. You need to plug it into a powered USB slot or the Apple USB power adaptor, which turns any wall socket into the equivalent of a powered USB slot. And the iCell requires a special cable to charge, which Satechi provides together with a convenient drawstring bag. Not a huge deal but slightly inconvenient and the charging cable is one other thing you need to carry and worry about losing.

 Disappointed Jan 18, 2011
By ThomasG
I was really looking forward to having this backup/traveling charging capability. However, right out of the box, the device did not appear to take a complete charge. There are 5 LED charge indicator lights, and it would only charge to level 4. The first use charged my iPhone to 100% one time, and to 80% a second time, without recharge of the device. The second attempt to charge the device indicated it only charged to level 4, but this time only charged my iPhone to 100% once, and to 40% a second time, before it was drained. Upon the third attempt the device would not charge beyond level 3, and would only charge my iPhone to 98% once, and it was drained. The product is a great idea, but did not deliver as expected. I returned this item.
The product was delivered on time. The packaging was very nice, even upscale. The construction quality appears excellent. The included instructions were weak, for example, it would be helpful to know what is a minimum or maximum charge time, especially since the device never indicated a full charge.

A powerhouse battery extender Oct 30, 2009
By Dennis E. Nienkerk
"Cruiseophile"
This product really exceeded my expectations and is an excellent value. I travel a lot and run through a charge of my iPhone 3GS at least once a day. The Satechi iCel 4400 is able to charge my phone at least 4 times before it must be recharged itself.
I especially like the soft drawstring pouch which comes with the unit.
As a bonus, it will charge my iPhone mini-speaker system and my Sony Reader (with a plug adapter) - up to 8 times on its own charge
It is a compact, very attractive and well-designed product; definitely one of the best iPhone accessories. Highly recommended.

Was not 'new'; didn't work as advertised. Apr 30, 2011
By Ryan G
*** IMPORTANT: This battery only properly charges from a laptop USB port. DO NOT attempt to use with a car charger, wall charger, etc. unless you confirm that it puts out ONLY 500 mA, and no more. See [UPDATE] section below, for more details. ***
[Capacity summary: was able to (carefully!) charge my Droid X **which has an extended internal battery with 20% more capacity** 1.3 times. If product worked as advertised, I should have been able to charge at least 2.3 times, assuming my Li-ion phone battery is at the poor end of the charging-efficiency spectrum. Would expect at least 2.7 charges for Droid X with regular (non-extended) internal battery.]
Overall design is very nice; it looks very nice, shape is good, very attractive. But... several problems.
First, this battery was supposed to be in 'new' condition, but was very clearly (and heavily) pre-used; the box had stains, sticky stuff, and extra circular stickers on it (from where the previous 'owner' broke the seal).
Second, it didn't work. My phone (Droid X with genuine Motorola extended battery BH6X, which holds 1800 mAh instead of the usual 1500) could only charge from it a total of about 1.3 times, before the external battery was totally drained. I was surprised, so I repeated the test, and got the same results. I was super careful: I let the external battery charge for 36 hours; I waited til my phone was down to 30%; then I charged it up to 100% (cell was on; gps/wireless off; all tasks killed; screen off/no activity). I then disconnected the external battery right away, when the phone reached 100%.
I then repeated the process; I plugged the phone into the external battery at 30%. About two hours later, it was at 70%, but the external battery was 100% drained.
Very disappointing performance. It was only able to transfer 45% of its alleged energy to the Droid X (1800 x 1.3 = 2340 mAh, out of 5200), but Wikipedia says that Li ion should be able to charge at 80-90% efficiency -- so something is clearly wrong here.
I would stay away; I was worried when I bought it, noticing that many recent reviews (as of April 2011) had complained of the same. I think they're selling a bunch of their returned units. This really irks me, as I'm extremely busy, and really don't have time for this kind of stuff; I want to just buy a product that works and lasts, and I'm happy to pay whatever it takes.
[UPDATE]
Satechi contacted me. They claim that smart phone chargers provide too many amps, and that this fries the external battery. They recommend *only* charging from a laptop (where the USB is limited to 0.5A), whereas I used (in my two tests) chargers with 850 and 1000 amps.
However, this is no excuse; this is a design defect. You should be able to charge from any source, as long as it has at least 500 mA. Every other electronics device on the planet has circuitry to limit the amperage it takes in to what it needs, and gracefully rejects excess current. They tried very hard over the phone to convince me that this was not a design defect; I found this very disingenuous. Review remains at 1 star... sorry, Satechi.

 good battery extender for iPhone 3GS Mar 30, 2010
By Javier Ruiz
I bought this battery pack because I routinely run the battery on my iPhone down below 20%. I did not want to buy a battery-in-a-case solution such as the Mophie Juicepack because I have read many reviews that point to the fact that these battery-case solutions can significantly dampen the phone's ability to receive signal. The Satechi pack is a small battery that allows me to recharge my iPhone on the fly up to two times before it needs recharging, and it's relatively small footprint means I can carry it anywhere I go. Charging it can take over an hour. Just make sure you use a powered USB hub, or, of using a laptop, make sure you use the main USB port, that draws more power. If not, you will not be able to recharge the pack to full charge, and it will overheat the USB cord quickly. Finally, you can use the iPhone's own charger to recharge the battery, but only the old style, larger charger. The newer, smaller charger (sold with the newer iPhone 3GS) is not powerful enough to handle the power draw of the battery pack as it charges, and all it will do is overheat significantly while the indicator lights on the battery flash and the battery never really charges, which can potentially be a problem. So make sure whatever USB adapter you use to charge the battery has enough power output and draw to allow the pack to charge safely.
