Works well! With this charger I am now able to "Hot swap" the batteries on my MH25 Pro. I can also charge my other 18650's as well as smaller rechargable AA sized batteries.
It having USB-C is just icing on the cake.

Great small flashlight that fits into my palm or front pants/jacket pocket. Good alternative to my EDC35 when I don't need as much power.

I really liked this headlamp! The Nitecore NU30 is lightweight, comfortable to wear, and provides excellent brightness. It worked very well for me, especially in low-light conditions. The USB-C rechargeable feature is very convenient, and the battery performance was great. Overall, it’s a reliable and practical headlamp for camping, hiking, and outdoor activities. Definitely a product I would recommend!

Works well, but it just barely fits into my NVG mount. I might need to file on it a little bit to make it easier to insert. And I just wanted to echo the other review that it 'does' actually fit the HC75.

Great flashlight. Very light and very bright

Very bright, excellent adjustability

Great! It’s a nice thin battery that is much easier to pack than some of the other batteries I’ve tried from other brands

Love it - not really much to complain about. Could be nicer if they find a way to make the cable stick out less and eventually make it thinner but those are nice to haves. For what it is, it serves what I thought would be a pretty specific niche: Magsafe thin battery but charges phone via usb c cable instead of qi. Goes with me everywhere in my bag

I bought my first one at a police convention to carry in my pocket and two more to keep in my vehicles. The battery charge will last for months if not used, and a couple of hours of steady use. The thin, flat body design fits well in your hand, and the swivel head makes it convenient to use without removing if from my vest. There are three brightness modes and a magnetized end for hands-free use outside your vehicle. Highly recommend this flashlight for both professional and personal use. They also make great gifts.

The rechargeable upgrade is great, still able to use batteries also,never have to worry about losing power.

Work Good and Lasts Longer than originals.

Light is great, holds a charge

I am a police officer and this light is awesome. It clips to my carrier vest and I use it for hands free, or can take it off and clip it on very easy. I love the one lumen function to save on the battery for writing things in the car. (Most things are on the computer now though) it turns on very easily to reach 3 levels of intensity. Defiantly a great flashlight for police work.

Sent in a flashlight for a warranty issue. Nitecore team were quick to respond and send a replacement out. Solid customer service!

Nice charger
I like the indicators and status of the progress it shows
And the fact that it can charge two batteries at once
