5.0 out of 5 stars Possibly the best battery charger ever 3 Jan 2010
Verified Purchase
Not the cheapest battery charger, but this one has features you need, and its use will ensure a good long life for your new technology nimh batteries.

Duracell are hardly advertising them, but the batteries with this charger are the new technology low self discharge long shelf life batteries which you can charge and leave - without worrying about them discharging and becoming none-rechargeable after a couple of months.

It is not unusual for a charger to take four batteries at a time. But this charger treats each battery as an individual - you can charge a single battery, you don't have to charge two at a time (which most cheaper chargers insist on).

The charger measures battery condition at individual level for best battery lifespan (and you will see that no two batteries are exactly identical).

A useful extra is the USB connection which you can use to (slowly) recharge your phone or mp3 player using four fully charged batteries. Useful out in the country away from a mains plug.

The UK plug can be flipped off the unit to allow for other style plugs to be used, but none are supplied in this package.

And a failed battery (it happens) or accidentally putting an alkaline battery in - is indicated by a flashing light. (update) Note however a flashing light could also indicate you have just inserted a fully charged battery- the sensor used seems to try a short charge and then looks to see if the voltage has increased very slightly.

(update 15 months on-) On two of my chargers (I now have three I like them so much) the led flashed for one position for good AAA batteries, after a while, this seemed to be due to a poor connection (the AAA batteries barely touch the terminals) and a good clean together with ensuring the batteries were firmly seated, solved this one.

Highly recommended.

4.0 out of 5 stars Excellent mobile charger from Duracell 15 Mar 2010
By SpecialOrder937 TOP 500 REVIEWER VINE VOICE
Verified Purchase
I wanted a battery charger, mainly to supply batteries for a power-guzzling Magic Mouse, and chose this one because of its features and the Duracell name. It comes with four AA low self-discharge nickel-metal hydride (LSD NiMH) batteries, a relatively new kind of battery which reduces self-discharge, extending shelf life between charges.

The unit can charge batteries singly, and can charge a combination of AAs and AAAs. It also has a USB port that can be used to charge a device from the mains or from a set of charged batteries. It's touted as a "mobile" charger due to its compactness, but here is the one reason why it just misses out on being 5 stars: the mains plug attaches to the charger itself, meaning that you need a lot of space around the socket in order to plug it in. Thankfully, the space needed is upwards rather than downwards, but generally I find that a plug on the end of a cable is easier to use in most situations, even if you lose a tiny bit of "portability".

If looking to buy a set of AAAs to go with the charger I'd recommend the "Stay Charged" Duracells. These are the rebranded equivalents of the "Active Charges" that come with the unit, and feature the same LSD NiMH technology mentioned earlier.

Amazon are currently selling these units for [] - an absolute steal at anywhere near this price.

5.0 out of 5 stars Best Charger so far ! 23 April 2010
By Deep
Verified Purchase
I liked the product's design and the quality of the material used . Transparent cover to protect your batteries while charging and travelling. I liked the detachable mains plug which ensures ease of packing while traveling. Four 2000mA batteries supplied with the charger are very good and can retain their charge for a very long time if not in use.USB charging is very useful(extra value) as it works without the mains power supply too, i.e can be used as battery pack to charge ipod, iphone, ipad or other devices with USB charging cable. 12v dc socket to charge batteries in car(but wire not included). Two coloured LED lights indicators are easy to understand .It can even charge odd number of batteries(very useful) like single or three batteries at a time which is a big advantage . I will give it five stars with smile.

Bought another Energizer battery charger tempted by its blue digital numeric charge time display, but very much disappointed by its performance and functions, when compared to my older Duracell charger(which is 1yr old now as i am updating this review). So still 5 stars for Duracell charger.

5.0 out of 5 stars Good value charger 22 Jan 2011
This charger is good value, especially as it comes with 4 rechargeable batteries (which in my experience seem to have a very long life). I like the fact that each battery has its own status indicator (red = charging; green = charged) so that you can whip the batteries out as soon as they're ready.

The charger plugs straight into a wall socket, which is good as it means there are no annoying cables to get in the way (but could be a slight problem if your wall socket is hard to access).

I bought this charger with the intention of using it in battery pack/backup/emergency mode as a USB power source for my HTC Hero, so that when travelling I could easily charge up the phone using AA rechargeable batteries. I bought two, and both chargers' USB modes broke (a part of the USB circuitry must have burnt out) within 1 hour of use charging my HTC Hero. It would seem that the USB power mode is not compatible with devices that have a high charge current (2009 and newer smartphones I think). So, not very useful for me so only a two star rating overall. Perhaps if you have older devices that draw a lower charging current the device will work for you.

Now, the good part: the battery charger. The charger charges 1 to 4 AA or AAA (in any combination) batteries in 4 hours (AA, less for AAA), with full battery detection/overcharge prevention and bad battery detection. Also, each of the 4 charging lines are monitored separately, so there's no need to charge batteries in pairs, and batteries with different charge levels are charged the amount they need, rather than some fixed amount for all. As a battery charger this device is very well featured. The charger does tick quietly (cutoff timer in use) and will smell of plastic when brand new. Also you'll need extra space around the mains plug since the charger is flush to the plug.

Feedback from the LED lights is reasonable, but a bit limited: one light per charging lane solid red while charging, flashing red for bad battery and green on completion. A button switches a pair of blue LEDs from charge mode to USB mode.

The second good part is the AA batteries provided: Duracell ActiveCharge, which are the low self-discharge NiMH type, the best available AA batteries. Apparently they are rebranded Sanyo Eneloops.
