    Nikon MH-21 reviews

    MH-21 Quick Charger is rated 4.8 out of 5 by 68.
    Rated 5 out of 5 by from It just works! Needed this charger for the EL4a. It just works as perfectly as it is. The size is larger than I thought it would be. But I am happy to have this quick charger for the travel and high flips shooting. I have some reason to believe that Nikon should really consider to improve the quality of their power supply wire - and the connector/interface of the power adaptor. Those comes into play when i travel to the different zone with different weathers - in winter the wire is very hard. If you own an Apple laptop computer you know what I mean about power adaptor and their wires. However this is just my suggestion to make it even perfect as I wish.

    Rated 5 out of 5 by from Works just like it should. After losing my charger that came with the D3 I read the reviews of this product and the double charger I purchased this one. I didn't need the double and this charger works quickly and fine. No problems with it at all. Less bulky than the double charger, so uses less storage space in my camera bag. I haven't had it long enough to comment on reliability, but based on the performance of other Nikon products I own, I doubt if reliability will be a problem. If you need a charger for the Nikon battery, this is a good choice. I notice others consider it bulky, I do not.

    Rated 5 out of 5 by from Nikon quick charger The MH-21 is a good replacement for the charger that ships with the camera or to use as a second charger. The original charger (MH-22) has two battery slots but charges one battery at a time. If you want to charge two batteries at the same time you need another charger. I used this unit to charge a new EN-EL4A and it works as expected. It makes sense to have a spare battery for your camera and a second charger makes sense if you want a backup or you need to charge two batteries and you can't leave them charging over night. The less time a charger takes to fully charge a battery the shorter the battery life. This charger won't charge a fully discharged battery in an hour but doing so would likely shorten the life of a fairly expensive battery.

    Rated 4 out of 5 by from Just what you need for EN-EL4a batteries If you use a D300 with the MB-D10 grip and switch to the EN-EL4a batteries, you'll need either this charger or the slightly larger MH-22 dual battery charger. Both are fairly large when compared to the chargers for smaller Nikon batteries, such as the EN-EL3e, so for travel they are a bit bulky. However, the additional status lights and option for battery conditioning is a plus.

    Rated 5 out of 5 by from Needed for Charging EN-EL4/4a Batteries You need either this charger to charge EN-EL4/4a batteries or the MH-22 dual charger. This to my mind is the more practical of the two. It is larger than previous chargers, making packing for travel an issue. Lights on charger are useful, reflect charge percentages 50/80/100, as well as calabration lights.

    Rated 5 out of 5 by from MH-21 Quick Charger Recharges a discharged battery in roughly an hour and a half. It is able to switch power voltage from 100-240v. A nice feature if you are traveling in Europe.

    Rated 5 out of 5 by from This a better charger than I expected I reluctantly ordered this charger to go along with the Nikon EN-EL4a battery that I purchased at the same time. After receiving the order and using it to fully charge the EN-EL4a to full capacity from a 50% level I was surprised by how quickly the process completed. I've only used the charger that one time so have no way to predict its reliability. The unit seems to be well built and its weight & size lead me to believe that it is constructed with components intended for heavy-duty usage. If I encounter any performance issues with this charger in the future my review will be edited to reflect that.

    Rated 5 out of 5 by from Best to have 2 of these for heavy shoots Hard to find flaws in a charger that charges as expected and works like a charm. I bought a second one of these because I wanted to be able to charge 2 batteries at a time, or take one with me and leave the other at home. Nikon also sells a dual charger like this, but I prefer the items separate for those just in case moments. I've only recently started using Nikon gear, and am very much impressed with everything I purchased. The D2x cameras (although discontinued) work flawlessly.
