It works - but it's tricky and picky 18 de diciembre de 2012
Por David Held - Publicado en Amazon.com

I bought the AA battery powered version of this charger after having had to rely on the generosity of a neighbor with a generator to keep my phone charged during the 4 days I was without power after hurricane Sandy. I had a single AA-powered charger that I had picked up as an impulse purchase at TJ Maxx that was pretty much totally useless, but I liked the idea of a battery-powered charger and figured that capacity (number of batteries) was the real issue.

The tricky part of using this device is getting the battery cover back on after you install the batteries. Other reviewers have already mentioned that it's very difficult to determine the correct battery orientation - the markings inside the battery compartment are virtually unreadable under any lighting conditions due to reflections from the glossy black plastic case. But what is worse is trying to slide the cover back on, getting it set correctly in its grooves, while keeping the batteries compressed down on their spring connections. It took me so many tries that I almost gave up on ever being able to try out the charging capability - the cover either just slid off, or went on crooked, or didn't snap into place completely. I was afraid I was going to break it before I would ever get it put back on correctly.

The picky part is that the unit seems to only work with the newest, freshest batteries you can possibly find. I put in a set of Duracell alkalines that were guaranteed fresh until 2017 and only got a 5% test recharge out of them before the unit's LED turned red indicating that the battery charges were too low to be used - then the LED refused to light at all implying that the batteries were drained. However, all of them subsequently tested fine on a battery charge tester and worked fine in a flashlight. I tried another set with the same 2017 date - and this time the LED lit up blue, indicating that they were good, but as soon as I plugged in my phone to charge, the LED changed immediately to red and shortly thereafter turned off and charging stopped. However, the batteries again tested fine and worked fine in a flashlight. I finally tried a set of batteries with a fresh through 2022 date and they actually worked - I was able to charge my HTCThunderbolt from 46% to 97% over the course of an hour or so (sorry - I didn't pay attention to the time). After that, the charger indicated that the batteries were drained - but once again, they tested just fine with a battery tester and worked fine in a flashlight.

Bottom line, this charger does actually work and will re-charge a phone, but only if you have super fresh AA batteries to put into it - and even then it won't drain them completely, so they'll be usable for other purposes afterwards, but just not to keep charging your phone like you'd want or expect.

Works Great! (But I wouldn't recommend alkaline batteries) 16 de agosto de 2013

I have used this device now for a few days and it is working great. I have used both high capacity and low self-discharge NiMh batteries and both have provided ample power to charge both a blackberry Q10 and a Samsung Note2 (both require allot of current to charge). The device sustains charging power for over an hour. For those who are having problems when using alkaline batteries, I would recommend switching to rechargeable, or if that is not an option purchase disposable batteries that are designed for high drain devices such as lithium batteries, the cost of the high drain disposables may be a few times more than a basic alkaline, however the cost per amount of power you will be able to achieve from the high drain batteries is much less. The internal resistance in an alkaline is too much to provide the high current needed to produce the 1amp charge the Verbatim power bank can supply, and because of that the voltage rapidly drops when a high drain device is plugged in and the blue power light will change to red. I did test this and inserted 4 Rayovac std AA's and plugged in my phone, it charged for only a few minutes before the indicator changed to red. I pulled out the batteries which had become noticeably warmer and put in a second set or Rayovacs and this time plugged in an old MP3 player with and that worked just fine and the verbatim was able to charge it fully from the alkalines. Moral of the story, I would only use rechargeable batteries unless you are only going to be charging low powered devices.

I think it's probably awesome? 16 de junio de 2012

So, I thought it would be nice to have something like this. i.e., a device that takes 2 or 4 high capacity AA batteries, and, with the help of a simple circuit board to boost and regulate the voltage, to provide a nice charging current for my smart phone. I noticed there were three price points for this type of device: There's one that's only like $3 or $4, then there's one that's around $10-$12 that I saw on another site, then there's this one by well-respected Verbatim on the top end. It was clear from reviews that the cheap one needed some slight mods to be useful, and the mid priced one seemed to have some reviews saying it was "cheaply constructed". So, I said, WTH, I'll just buy the "good" one.

My thinking on buying a device like this: I play a lot of long poker tournaments, and it's just not really possible to get a charge in on the phone in the middle of the Venetian or other casinos. It would be helpful if I had a backup to charge my phone.

I think if I could do it over, I'd buy the one that costs about half as much as the Verbatim one. The device is all plastic, I sort of expected maybe I would have something a little more sturdy if I got the Verbatim one, but I didn't. It does have a pretty pimp blue and red LED light around the port (indicating a "good" charge remaining, versus a "nearly dead" charge), so maybe I paid an $8 premium for pimp LED.

A lot of people complained that the cheaper devices got hot under load. This one does not--it barely warmed up at all whilst charging. Clearly, the output is steady voltage, even as the batteries discharge, and I popped her up on an oscilloscope under load, and they've clearly made a decent circuit here. I put four 1600 mAh tenergy premium NiMH batteries in here, and I got just about one solid charge on my Samsung Epic. Maybe a little more.

The device is about exactly the shape of a lipstick tube, plus 50% in all dimensions. It comes with a very short (4 inches maybe) microUSB to USB cable, which apparently has the data pins shorted out (this is normal and necessary for high speed charging). I don't know if the device USB jack has the pins shorted, or if the cable did, I didn't check it; if it is the latter, then the cable that comes with this should not be used in a computer USB jack since it will draw more than 500 mA rating.

All in all, I'm happy with it, it does what I expected...I think though that I would have been 90% as happy with the devices out there that cost half as much.

There is an admonition in the instructions that says NOT to use it on an iPad. I am not sure why--maybe you can't get a full charge. But, it will definitely charge your smart phone. The other guy that dropped a 1-star rating on this because of the iPad thing, that's really out of line, since the device otherwise appears well enough constructed, and does its job.

Better than juice pack case.. 16 de agosto de 2012

It's what you'd expect. It takes your choice of 4 AA batteries (rechargeable/not included of course) and has a female USB jack to charge your stuff. Has a nice on/off switch that glows blue when on. The + - battery labeling could be better but whatever, you'll figure it out. Works great with my iphone 4 when I'm camping without mains for a few days. I'd give it 5 stars if were $9.99 but it's not so, 4 stars.

Not compatible with Energizer Lithium L91 AAs 3 de abril de 2013
Por report violation - Publicado en Amazon.com

This charger works with Alkaline and NiMH batteries but is NOT compatible with Energizer Lithium L91's. This is a major bummer as I wanted a charger that I could keep in my car long term for emergencies. Alkalines will leak and NiMH will eventually self discharge over long periods so I thought this would be the perfect solution when loaded with Energizer L91s. Wrong. I think the overall voltage when using 4 Energizer lithiums in series becomes too high and triggers some sort of protection cutoff. I tried with both the Energizer 9x and 4x lithiums and they both failed.

The charger works great with Eneloop 2000 mahs (almost 100%). I can barely get from 0 to 40% on new Duracell alkalines. I guess that's still better than nothing if needed.

No problem with the battery cover as reported in other reviews. Just need to carefully line up and slide in with steady pressure. There are no springs and loose metal parts to bend or damage (which is what I thought.)
