Pros offset by the cons - slow and not "mini"
on June 4, 2012
Overall, the pros of the Duracell Mini Charger (CEF-20) are balanced by the cons. It's OK, so if you're looking for an inexpensive but smart charger with good build quality, and don't mind that it's slow and bulky, then it may be a fit for your needs. But for those willing to spend more, there may be better options out there. (Check NLee's most recent recommendations, that's the go-to source for battery and charger reviews.)
"SMART" CHARGING: Each battery is charged separately, so you get the right amount of charge to recharge each battery.
INTERNATIONAL VOLTAGES: It can handle 110 - 240V, so all you need is an adapter for the prongs or access to a US-style "shaver" outlet.
FOLDING PRONGS: It will play nice with the other things in your luggage.
SLOW: As NLee notes, the current this outputs to charge is low (280 mA AA, 110 mA AAA). Duracell estimates 8 hours to charge.
NOT SMALL: To me, this seems about 30%-40% larger than it needs to be. It's 4.5" long, 2.25" wide, and 1.6" thick. (You can get a sense for it's not-mini size by looking at the photo - those are AA batteries in the pictures, and the charger is much larger. I have a 4-battery charger that's not much bigger than this. That picture of someone putting it in their jeans pocket is do-able but ridiculous.)
This "mini" charger is longer, wider and thicker than it needs to be. Someone should have told the designer what "mini" means.
Also, the color of the cover is a lovely metallic color (green in my case), but the cover seems pointless or worse - charging batteries get hot. The cover is pretty but superfluous.
