Haven’t put it through extreme paces yet, however, the initial take audit is that it is terrific with just the right amount of power and lasting on the battery combined with very lightweight. Well, done, Nightcore.

Great light for slipping into a pocket, bag, purse or backpack for everyday use. The modes are nicely spaced and run times are good. The ability to tail stand while on is a feature I wish more AA lights had or kept.

The included rechargeable AA battery means you get better performance and run time and don't need to worry about old Alkaline batteries leaking in your emergency light stashed in the glove box or your work backpack if you don't use the light all the time. While the AA form factor allows you to grab back up batteries pretty much anywhere if you needed and keep the light on until you could recharge.

The only thing that would be nice to see added would be an ultra low mode at 1 - 10 lumens for when you just need a little light to navigate but don't want to illuminate the whole room/area or blind yourself. Other than that one little thing, this is a near perfect single AA flashlight!

Not bad battery does the job I got two of them they do last awhile but again it all depends on how you use it the brighter you use the flashlight the less it last like everything else.

Best little flashlight I bought does the small enough to carry around at home and work.

Excellent! Thank you

I really like the design and the tech and the double locking mechanism super bright and not to light or heavy for a keychain light.

I needed my laptop for a 3 day wildness trip in Montana. The Nitecore Carbo 20 20,000mAh did a remarkable job and it also charged my phone.

Its small and lightweight. Fits on my work Keychain perfectly. I use it mostly as a box cutter. I would purchase another for my back pack when I thru hike the Appalachian Trail in the future. Very cool. Please send me a discount code.

Like every thing else you guys have it is great

I bought these to upgrade a couple of my AA lights and stretch out the run time...so far so good

This was a great flash light, loved it for the few days it was in my possession. Unfortunately it fell out of my pocket packing up my tools. 5 Stars would order again.

Its small, its very light, and it gives me 2.5 phone charges. This was the perfect insurance policy I needed for traveling and hiking in remote places where I would be relying on my phone all day. It would be cool if it came in a little carrying case with a pouch for cables for people like me who have an iPhone with the older Lightning connection.

I like that it is bright and not too big to carry around everyday. It is handy to be able to see the charge level and to have it retain the last brightness level used. Battery life is very good and I like that it is waterproof. I hope Nitecore comes out with a hard plastic tactical quick draw holster, as it is hard to quickly put the light back one handed into the included nylon holster.

This is a good pairing with the battery charger.

The charger appears to work well for a wide range of batteries. I'm looking forward to using it on an upcoming international trip.
