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

Fantastic customer service

I thought this battery had circuitry that kept it from dying if I ran the charge down too low. That way, it would be able to recharge. That didn't happen. So, I had to buy more batteries. It is the only battery that works in my EC11 flashlight.

All you could want in a head light. Three colors may be overkill but having real color rendition is a useful feature during evening bike rides.

Adjustments are easy while on the head or helmet and impressive run times even on the higher settings.

Great product. Brightest headlamp ever!

Mounts for lights. Great customer service to send me extra light mounts for molle vests. Arrived quickly.

Excellent Headlamp

The Nitecore P40 flashlight is excellent; I’ve already tested it and it’s fabulous. It has a long range and is suitable for all purposes—I highly recommend it! 👍👍👍

Does exactly what I bought it to do.

This thing is amazing! Not sure how they stuffed 20,000 mAh in this tiny power bank but they did it! If you like the outdoors and all mother nature has to offer, this is the one you want. It's IPX8 waterproof rated so rain is no issue. I really like this power bank and I hope it holds up. Time will tell.
