Story and photos by Dan Clements
Are you the less-than-proud owner of a bulky, single-battery charger similar to the Sony, Nikon, and Canon models above? Wouldn’t it be great to have a lighter, more functional unit that charges two batteries at a time? Well, you can, as it were, be in charge.
My frustration with bulky external battery chargers peaked about two years ago during a photo trip in Ranthambore, India. By way of background, Nikon has been my go to camera system for decades, but the battery charger that ships with the D750, D850, Z, and other models is one of the most poorly designed accessories I have ever used. It is bulky, heavy, and the plug-in system looks like it was designed by Rube Goldberg.
At one point on our India photo trip I tried to charge batteries, but the charger kept dropping out of the electric wall outlet. Yes, it was that heavy! I had to stack a piece of luggage and a field guide beneath the outlet to keep the charger, battery, and adapter plug from falling out of the wall socket. When we returned to our Seattle-area home, it was time to look for alternatives. There are many choices of third-party chargers, some better or better suited to my needs than others. After doing a bit of research and reading recommendations on Amazon, I purchased the EN-EL15 RAVPower Battery Charger Set unit for $38 US. It has performed flawlessly.
Here is what I like about it. For starters, it is smaller and less than half the weight of the Nikon MH-25 charger (4.5 vs 1.8 ounces). It also charges two batteries at a time. That is a big advantage for someone ,like me, who does a good deal of cold-weather and night photography, both of which eat up battery power.
Next, it utilizes USB to micro-USB charging cables, another feature I have really enjoyed. On the left side of the photo above, for example, the USB plugs directly into the CleverTrips power converter I use when traveling overseas. In the past year I have been in Morocco, Russia, Brazil, Paraguay, Argentina, Finland, and France, and have not had to repeat the luggage/book trick to keep the charger plugged in.
The USB charging cable also has greater flexibility than a “regular” plug. The right part of the photo shows the unit plugged into the power bank I use in the field. It can also be plugged into the USB ports in most modern vehicles, so you can re-charge batteries while on the road.
RAVpower makes chargers for Nikon, Canon, and Sony camera systems. While the unit ships with a nice 15” flat USB to micro-USB cable, I use a multi-cable 3-in-1 charging cable to reduce the number of cables in my camera case.
While I have not done true benchmark testing of the time both units take to charge batteries, the Nikon generally takes about two hours to charge one battery, and I am estimating the RAVpower unit takes about three hours to charge two batteries. I shoot with a grip that contains a second battery, so almost never have two dead batteries.
So, you owners of bulky, single camera battery chargers, consider tossing those units and migrating to a lighter, more functional, dual-battery, USB charger!
