I was looking around for a very compact intelligent travel charger instead of lugging around my Maha MH-C9000, which is enormous with it's separate power adaptor.

I discovered the Lemar R2G804U 4 Cell charger, it has a charging rate of 600mA which means the cells don't get too hot. It charges a set of 4 AA charges in 4hrs and a bit longer for the AAA's.

What I like about the charger is the super compact size, fold back AC prongs, worldwide universal voltage, and intelligent charging control like -delta V, max time, overcharge protection, reverse polarity etc. A lot of small chargers are only timer based and don't have the collapsible AC prongs.

It also has another feature which is a USB charging port with a output of 500mA for charging a range of USB based devices. Mobile phones require at least 500mA to charge.

The unit comes bundled with 4 Lemar R2Go AA batteries which are supposed to be LSD's like Eneloops and Maha Imedions, they have a nominal capacity of 2150mah.

There are a couple of negatives, which are not significant
1) You need to charge pairs of batteries
2) When using the usb port you can't charge batteries as well.


All up very happy with the unit, as it's super compact, has a good range of charging methods and protection and the usb port means you don't need to carry around another adaptor.

For $17.00 with 4 x AA R2Go batteries it is extremely good value for an intelligent charger, as the set of batteries are already 12.00 by themselves.

Really small size.

It's about the size of the MH-C9000 power adaptor.

Thin cross section, allows it to be slid into thin bag pockets. Notice the USB port, one of the few AA/AAA chargers with this feature.

Fold up AC prongs, make the unit slimmer.

I looked at the Sanyo charger as well, great charger/ similiar specs, but there is a bit of a price difference, also no USB support, which I wanted for charging the blackberry.

I already have the expensive MH-C9000 so I didn't need a lot of features like combination charging etc. that why I went with the Lenmar.

I think this is slightly different in that it uses a usb input to power the charger, what I wanted was a usb output to recharge other mini usb based phones etc. from the charger connected to the AC.

I just analyzed the R2Go AA batteries it looks like they have a capacity of around 2070 mah, the issue is how long they will hold the charge for.
