The Duracell Mobile Charger (CEF23) is an extremely versatile charger. It actually has two operating modes, as selected by the MODE button:

1. As an AA/AAA NiMH battery charger, or
2. As an USB charger for USB-powered devices.

In battery-charger mode, the unit is a smart charger that accepts 1-4 AA/AAA cells in any combinations. The charger can be powered by either 100-240V universal AC input, or 12V DC input. This means you can also operate it from your vehicle's cigarette lighter adapter. Note that the car adapter is included in the CEF23DX4N, but not in the CEF23DX2.

The charging current is 550mA for each AA/AAA cell. So it takes about 4 hours to full charge up the included 2000mAh low-self-discharge cells (which are the Duracell-equivalent of Sanyo eneloop). I consider this a good compromise between shorter charging time and longer battery lifespan. Once charging is done, the current is reduced to 25mA (actually 0-50mA pulsed at 50% duty cycle) in trickle charge mode.

One really nice feature of this charger is that it has four individual battery status indicator lights. The status light for each cell turns RED when charging, GREEN when the cell is fully charged. It will even blink if you accidentally inserted an alkaline cell.

In USB charger mode, the unit generates a regulated 5-volt supply at its USB socket. You can then connect an USB-powered device (such as IPOD charger) to this unit. Input power for this USB charger can be from one of the following sources:

I've done a lot of research on batteries and chargers, and I have to say I'm impressed with this charger. I am a photographer, and my fancy flashes are only as good as the batteries they use. Other reviews have already stated the high points: gentle charge rate (550 mA is great); individual charging of batteries (absolutely vital); intelligent shutoff (does not overcharge). On top of these, it runs off of 12V and any AC wall power in the world (120-240V), and it charges USB devices. It also will charge a USB device off of 4 charged batteries. It's a dream come true.

One thing to note: You cannot charge batteries AND charge a USB device at the same time. You have to pick one or the other. But this is a very minor issue for something so functional, portable, and inexpensive.

Assuming it doesn't die in two months, this is the best consumer charger that is widely available. (I also have the Maha C-9000, which I love, but is not for the faint of heart. The Maha C401FS is also very good.)

If you're even considering buying one of those 15-minute chargers, PLEASE don't. It will destroy your batteries by cooking them at a high temperature. Buy this one, instead. Just get an extra set of batteries to swap out while the others are charging, if you need the quick turnaround.

First, a note on what's included: 2AA, 2AAA, a charger, and a car adaptor. It does not come with a usb cable. You can see the customer photos I uploaded.

As noted by others, these batteries are "highly similar" if not identical to Eneloops. So the batteries are great.

For AA, I like the charger included in this kit more than the one in this Eneloop kit for two reasons:

1. Each slot has its own individual indicator so you know which battery is done. Equally importantly, you can detect bad batteries in a set. Say you always use four as a set but one suddenly finishes charging a lot earlier than the other three, it's time for testing. (For testing, I use Maha MH-C9000.)

2. It charges faster, at 550mA, so the 2000mAh AA batteries charge in about four hours.

Unfortunately 500mA is also how it charges AAA batteries. Contrast this to the Eneloop charger in the kit above: 300mA for AA and 160mA for AAA. We see that the Eneloop charger is a lot more gentle for AAA. (I won't charge my AAA in this Duracell charger.)

I bought this based upon the engineer guys review. I'm happy I did! It works perfectly for all of my rechargeable batteries. I have some older ones from Rayovac, some from only half a year ago that are Energizer and a handful that I recently bought that are Rayovac. They all charge perfectly in this device. I consider the 2 AA and 2 AAA that come with it a bonus. It doesn't get hot and it's not noisy either. You can plug it into just about anything to boot! :D

I have bought several different kind of portable chargers for my Apple iPod classic 160 GB Silver (6th Generation) and my Creative Zen Vision:M 30 GB MP3 and Video Player (Pink). The first one was a solar battery/charger and it was a piece of junk. The second one was a box powered by 4 AA batteries and it broke in a very short time.

Then I saw the reviews of Duracell Mobile Charger With 2AA Pre Charged Rechargeable Nimh Batteries, CEF23DX2, I bought Duracell Mobile Charger With 2AA And 2AAA Pre Charged Rechargeable Nimh Batteries, CEF23DX4N that includes a car charger. It did not charge my iPod and Zen either. It only charges my other smaller MP3 players.

Then I got Xantrex Technologies 852-0281 XPower PowerSource 100 Watt Inverter. It works even for a very small laptop, but it is a bit too heavy for travel or on-the-go.

Finally, I bought Tekkeon TekCharge Mobile Power and Battery Charger. It charges all my portable divices that can be charged through USB port.

Of course, this is a very nice charger for charging smaller mobile divices and AA batteries.
