I was a little skeptical upon purchasing this but I was pleasantly surprised at how well it works. On the minus side, the battery does pop out of the holder sometimes but once it is secured firmly in the battery holder, it does charge.

On the plus side, it comes with a car charger adapter that works great for those times when you've forgotten to charge the battery and can do so from the car on the way to a venue.

Nice charger and doesn't take up much room in my desk because of the other chargers I have to store too. Works great and would recommend it to anyone who needs a charger for the CRV3 battery.

East Coast Photo, Liberty Photo, who? Amazon lists it both ways. My packing slip says Liberty, so they and Amazon take the ding. It could have been returned to Amazon that way and they just "re-gifted" it. No way of knowing.

NO paperwork at all. Inside the box this was in a used, pre-crumpled, dingy, stuffed back into the box bubble bag.

HELLO. It is against the law in the USA to re-sell used electronics without notice.

I have NO idea if this is working correctly--charging, done charging, thinking about it, etc. I bought it for my GPS and leave tomorrow, so no time to do the return/exchange thing.

I purchased this mini charger, along with two matching Synergy CRV3 battery packs, for use in my wife's Olymmpus, FL-36R, off-camera electronic flash. The flash normally uses 2 AA alkaline cells. The CRV3 pack is equivalent in voltage and physical size to the 2 AA's. According to the Olympus manual, using lithium-ion packs, or lithium AA cells, will result in shorter recyling time between shots. (The Olympus brand charger and CRV3 packs are no longer available that we could find.) Anyway, the charger worked fine and both Synergy packs charged up as expected. HOWEVER, the Synergy battery packs WILL NOT OPERATE the flash unit! Put 2 AA's in and it works fine. Put the CRV3 pack in and... nothing! A multimeter test showed both packs at the required full-charge voltage of 3.9 volts. Seems the pack contacts are not mating properly with those in the flash body. With plastic guides limiting your choices for insertion, it is impossible to install them any way but the right way. We eventually gave up and purchased NON-rechargable lithium AA cells which work fine, although a bit pricey. So, we have a nice little charger and two battery packs that, right now, we can't use.
