Will destroy your cellphone Battery
This chager and all the other AA battery type chargers will destroy your cellphone battery. Apparently, the chip inside your cellphone battery will get fried the 1st time you use one of these AA battery charger and your battery will discharge at a rediculous rate once it is disconnected. I have two of these battery chargers and thought it was a great idea. i used to get 8 hours out of my battery fully charged, now, I'l be lucky if I get 1 hour from it after a full charge. Once your battery is ruined, it's ruined for good. They should ddefinitly stop selling these kinds of chargers and somebody really do need to do an investigative piece on why they are being sold because it does they do destroy your cellphone batteries. AA batteries are incompatible with the batteries that are in you phone.

Does as advertised
This is great. I use it for emergencies only at first, but now realize that it is really convenient anywhere. Since it takes batteries it really becomes cost effective with rechargeables. So long as the batteries are good, this will work fine. Not much can go wrong except physical abuse. The only draw back is I can't carry this on me 100% of the time as it is a bit too big for my jean pockets with the cord and all. It never leaves my car though.

7 Hour Rechargeable
This product works great. My wife needs it for her long stays when she is getting her chemo treatments. I rely on Rayovac Products.

Nothing great about this at all.
This product did not work. I did not get to use it once. I put batteries in it and they died before I got to use it.Ridiculous to keep batteries in my purse loose just because this product runs down batteries if you keep them inside. I will not recommend this product. Batteries were also brand new and Rayovac. Figure that.

Since upgrading my iPad to IOS7, I have found that the battery doesn't last as long. When a friend showed me her charger, I was thinking it would be the answer to my problem, when away from electric power source. Was very disappointed when I connected my iPad to the charger and it read "not charging". I then plugged it up to my Galaxy Note and it is charging, so there is nothing wrong with the charger itself. But, as noted by others, it will NOT charge an iPad.

Ipad charger NO
I purchased this as the box indicated to recharge my iPad while in meeting. It does not charge iPads at all. Works good for iPhone but failed the test as it indicated for iPad. Very disappointed.

Cool product will mention to customers.
I bought this to use with NiMh rechargeable batteries but was really more impressed with its performance with alkaline cells. It's clear this is a simple joule thief and a very efficient one as I was able to charge a 900mAh lithium ion and a 2200mAh from 3.92 to 4.1 at 1/4 C rate. This breaths new life into alkaline chemistry batteries because this although their discharge curve is flat, their less than stellar discharge rate and energy density the do offer better long term storage capability than most rechargeable chemistries. This devices cuttoff voltage is clearly very low making a large pack of AA's and this device a must have for emergencies. A word of warning to other users that because of its low operating voltage this isn't ideal for rechargeables unless you plan to keep good track of them because this device would likely still operate at below nominal voltage for most NiMh and Ni-Cad chemistries.

Works with rechargeable batteries!
Cant believe it's only $10! I've been waiting for a product like this for a loooong time! It even works with rechargeable batteries! I waited for my iphone 4s to be completely drained and used 1400mah rechargeables and it fully charges it in about 2.5 hours! I think because its a slow charger it conditioned my phone, when my phone would be at around 10% life and I would make a call it would die on me, after recharging it with the rayovac my phone would work all the way to 1% giving me a more accurate reading! Havent tried rechargeables on my ipad mini but the RAYOVACS that came with it was able to do the job! I dont know how much actual time it will give but I'm impressed! THANKS RAYOVAC!

Doesn't work with rechargeable batteries.
I'm glad to have a product that I can use to recharge my camera while on a backpacking trip, but I'm disappointed that rechargeable AA batteries will not work, likely because of their 1.2v output. There is no reason that this product couldn't be designed to function well using 5 rechargeable AA batteries. Then, i'd be really happy. It is a real disappointment that so many products ignore the common use of rechargeable batteries.
