I Power Lithium Aa Rechargeable Batteries

I clearly did not understand that it didn't actually come with rechargeable C and D batteries, though instead they are adapters and you need to plug in AA rechargeable. Not sure how a AA rechargeable will be enough to power a D device....

Using Eneloop AA rechargeable batteries with my Nikon Speedlights ensures consistent flash power. I own several Speedlights, and there is no power fall-off during the discharge cycle. After a shoot, I can re-charge the Eneloops just to top them off with no battery memory effects. The long-term savings of rechargeable batteries, and keeping batteries out of landfills are highly important benefits of using Eneloops.

I'm a big fan of rechargeable batteries. Saves a ton of money in the long run. This charger and battery combo is perfect. I love the big LCD display. It lets you know the status of the battery and charging levels which is very helpful. I've had other chargers in the past that would just blink, or give a red/green light. Having a descriptive display is so much better, as you can gauge how much power is left or how much more needs to charge for the batteries to be ready. This is vital. It can also discharge the battery to refresh them. This is also a very handy feature to extend the life of the rechargeable batteries. It will not only charge AA but AAA batteries and I plan to get some AAA's to partner with the AA's that came with this. The batteries themselves work great and last a long time. I'm very impressed with the power and time they give. [I have received this product in exchange for my honest review]

The best rechargeable AA batteries on the market. They are able to power many different types of devices and hold their charge for a long time.

Efficiently holds my rechargeable AA batteries for my wildlife cameras!

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

Very versatile, You can use lithium batteries to power it

My rechargeable AA batteries are no longer loose at the bottom of my bag! I have 2.

It's a bit snug, but my rechargeable AA batteries fit in this pouch just fine.

This works super well with the Panasonic eneloop pro AA Rechargeable NiMH Batteries (1.2V, 2550mAh) that we bought. We haven't had any issues are happy with its performance. So glad we made the transition to rechargeable batteries and this charging station. We are going to save a lot of money by not buying dozens of AA batteries per month now!
