Just as advertised.

I shoot rapid fire with my D700 so freshly charged batteries are a must. This charger is quick and efficient.

Nikon MH-21 Quick Charger


from Houston  -  Hobbyist/Enthusiast

I misplaced my original charger and ended up missing some great photo opportunities since my batteries were all dead. I ordered a new one from Adorama. Prices are competitive and I am always satisfied with the attention that my orders receive.

Nikon MH-21 Battery Charger


from Harrah, Ok  -  Semi-Professional

I needed this for re-calibrating some used batteries that I purchased. Couldn't do that with the aftermarket charger that I had.

Outstanding Quick Battery Charger


from Bethel ME  -  Semi-Professional

I bought this to add an EN EL 4 battery and the BL-3 Battery Chamber Cover , to my Nikon MB D10 Battery Grip For My D700. I am very pleased with it all, a faster battery that does more high speed shooting , and long bursts between writing files to CF card . The battery itself lasts much longer and this charger charges very quickly ..I am very pleased

Pricey, but does the job


from Sydney, Australia  -  Hobbyist/Enthusiast

Charging the EN-EL4a for use with my D700. Quite expensive, but for the money it's quick and has more advanced progress readout. If it ever needs to be done, I'll be able to recalibrate the charging scale as well.

nice charger


from Frederick, CO  -  Photo Enthusiast

Got this for my EN-EL4a in my MB-D10 for D300/D700. Cheaper than the double charger, which I didn't need. Perfect for my needs.
