A very powerful flashlight. It feels comfortable in the hand, though it does get hot at its maximum power setting. I bought it in green, and it looks beautiful.

The headlamp is well made and provides light exactly where I want it. The price is negligible when compared to other lights.

Very bright with adjustable settings. Comfortable and lasts a long time

the build of their new 12K extended headlamp battery is way better than the first one they came out with this the 6K. it feels like a better build the USB cables attached to the battery and the headlight itself better. doesn't take that long to charge and your headlight lasts an extremely long time I would recommend this product

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.
