I have not found any phone that it will charge.
Zero
Now the phone can't charge any farther, and if you leave it connected, it sometimes seems to drain both the phone battery and the AAs.

I tried using Sanyo Eneloops, Duracell Alkalina Ultras, and the included "ZAP" branded NiMh batteries.

Wow! what a great little product. There are other models out there which are sold by other companies in diff. colors ( black ) which claim to be better. They are all the same item. This one is White made by the same manufacturer. Yes, the black one with silver looks more expensive with better pic. but it's the same exact thing in a diff. color. I was looking for a recharger like this which took AA or AA rechargeable batteries so I could use anything if needed to power this unit. I do a lot of camping / mountain bike riding and if using EVO cell phone as GPS device I needed much more batt. to take with me. I have extra 1500 mAh cell batt. I can take but if you have used GPS nav. you know it sucks the juice. This baby can use 4X 2500 mAH rechargeable batteries giving me 10k mAh for a long day of power consumption without worry. If I some how burn up those batt. I can pop in another 4 - AA and keep on going. Then when I get home or back to vehicle I can recharge those AA rechargeable batt. in my 15 min. Energizer charger if in a hurry and go again. Point is it's as versatile as you need it to be. Some chargers like this use built in battery so in 2-3 yrs. when that batt. will no longer hold a charge you throw it away and buy another where this model just needs AA batt. since it's basically just a batt. holder with USB port. nothing fancy. It has 4 lights and test button so you know batt. level. You only have 1 USB port where some other much more expensive models have 2 ports. For this price you can buy 2 of these and still pay less then the 2 port models. If one fails you still have a back up. If you buy the expensive built in batt. unit and it fails your out of luck. As you can tell by review, I recommend this item vs $75 extra life batt. and other rechargers I found.

The only drawback I've encountered with this gadget is that it will discharge the batteries in the device you're charging if you leave it connected after it's fully charged. It has no diode to prevent this, so this gadget is more suited for powering devices directly, rather than letting them sit for a full recharge. For example, if your MP3 player runs out of juice on the go, and you need a power source for immediate use, this would be perfect. Also, the included batteries are a little weak (1200mAh), but that's easily corrected by installing a new set. So far, I've used this device to charge a Sansa Clip MP3 player, a Motorola Razr cell phone, and a Sanyo SCP2400 cell phone. I'll update this review with more details as I get more use out of it.

I purchased this as an emergency power supply for my Droid X and was momentarily miffed to find that it did not come with a micro-USB tip for the charging cable. After about 30 seconds I realized that my standard USB charger cable for the DX plugs right into the Zap unit. With that worry over, I fully discharged/recharged the included 1200 mAH NIMH batteries in my MAHA charger to ensure they were as charged as they could be and tried it out on my then-depleted phone. It charged the phone about to about a quarter full and petered out. I replaced the NIMH batteries with a set of Eneloop hybrid AAs and after charging the phone, the Zap pack still showed half full. As the previous reviewer said, this unit may be better for powering your phone directly in a pinch but either way it seems to work well. Since this is an "emergency" power supply for me, I decided that that tossing the supplied batteries and replacing them with a set of hybrids will ensure plenty of power that won't self-discharge in a couple of weeks (the nature of NIMH batteries). The option to slap a set of alkaline AAs in it for that emergency when your emergency power is depleted is another point in it favor.

Bottom line...nice little unit that works as promised but could have been $5 cheaper (and 5 stars) if shipped without the crappy included batteries.

This seemed like a great device on paper -- it can both charge AAs (with the AC adapter) and use those AAs to charge electronics via USB (and comes with a startling array of USB->device adapter tips).

Unfortunately, it doesn't play nice with the iPhone 3Gs. I tried using Sanyo Eneloops, Duracell Alkalina Ultras, and the included "ZAP" branded NiMh batteries. No dice. The iPhone didn't even acknowledge the device when the Eneloops or the ZAP batteries were installed. With the Duracell Alkalines, the iPhone briefly flashed the charging icon, then quickly put up the yellow warning sign and accompanying text "charging not supported with this accessory." This was all using an Apple-brand USB->iPhone cable.

This is really three devices in one:
- With rechargeable batteries, you can use it like the other common recharge-your-gadget devices that are generally more expensive and have proprietary battery packs. It includes adapters for nearly any cell phone, and it has a USB slot that allows you to plug in any device that can be powered over a USB cable.
- If you find yourself with all of your batteries dead, you can throw in normal alkaline AA batteries that can be purchased anywhere.
- You can plug it into an AC wall socket (US-type plug) or into any USB type A power source (the USB slots on nearly any computer) and use it as a NiMH AA battery charger for any other devices you have that take AA cells. There's no need to carry a separate charger when traveling.

The only problem I have with this thing is with the included batteries. They are advertised as 1200 mAh, and if that were true they would still be lame, but they don't even come close to their underwhelming rating. I discharged them and fully recharged them with my charger, and none of them held more than ~250 mAh. I ran them all through a refresh cycle (repeated discharges/full recharges until the capacity seems to have plateaued), and still none of them held more than 300mAh. For reference, a normal alkaline or any decent NiMH rechargable AA will generally have 5 to 10 times this capacity. These batteries are completely worthless, and mine went directly to the battery recycling bin. Plan on buying 4 half-decent AA batteries to go with the charger. (Eneloop are great, but if you don't need the batteries to hold a charge while in storage for months, you can go with a cheaper name brand. Or you don't need rechargables at all if you plan to use disposable AA alkalines.)

Despite the terrible batteries, I liked the device itself enough that I purchased a second one. For such a multi-purpose gadget, it's a good deal.
