An absolute beast of a flashlight. I was hoping it would be bright, but holy cow, this exceeded all expectations. I love that it comes with a rechargable battery as well as a battery holder to power with AA's, and it even includes Duracell AA's in the box. To me, it looks like the battery cell provides a bit more power and is slightly brighter. To those reviews saying the power level is not adjustable, what are you talking about? Each time you hit the button it drops a level. The lowest level is very dim, then it goes to a flashing mode before the next button press turns it off. As others have mentioned, being able to focus the beam a bit tighter would be nice, but with other flashlights, that's typically a cheat for making a weak flashlight brighter. This monster doesn't need to do that. It's like having the power of the sun at your finger tips. And other reviews that mention the battery not charging, there are two USB-C ports on the battery cell. One is for charging and I believe the other is a pass through port so you can plug in another device and charge it at the same time.

Couldn't get to work with AA batteries or the rechargeable. DOA

Very bright. I like you can use either the USB rechargeable battery or the AA batterys.

Very poor quality. Seems cheaply made. For a $40 flashlight, I expected much better. The beam does not focus as much as I would desire and the brightness is no better than a cheap $10 flashlight.

I like the brightness of this flashlight is and like having the option to use rechargeable power or AA batteries, especially for emergencies or power outages. It feels sturdy and easy to use, with different brightness settings depending on what I need. The flashlight does get warm after using it for a while, especially on higher modes, but overall it performs well and gives me confidence keeping it at home or taking it outdoors.

Bought the flashlight because it looked very promising and most members mark products are very good. Not this one. Oh it's sturdy enough. But it only worked briefly. Was difficult to make work with either the batteries or the rechargeable, and a very small rubber washer from somewhere inside the compartment broke. Since then it's not worked since. Don't waste your money!

It was too expensive for a junk that won't work as expected. I keep it plugged overnight to charge it and the charging lights stays red and never turns green, the first couple charges it was fine, after that don't expect to have a full charge. Another negative feature is that it gets hot to handle after you use it for few minutes. Don't get lost in the forest with this light in your hand.

It's a decent flashlight. Its bright, nice size and dual power capabilities is nice. Two drawbacks in my opinion, the annoying yellow halo around the edge of the beam and nowhere in the instructions does it say what kind of charger to use. Yes, I know it's USB-C, but it would be nice to know what wattage charger to use.

Looks nice and feels heavy duty but won't keep charge. Using it after a charge will only work for a few minutes and it's dead. Also gets really hot. Not good quality. Very disappointed. I have the smaller versions and they seem to work pretty well. Just not bright enough.

This flashlight has four failures. 1) it fails to turn on after charging the flashlight. It can't be unlocked! Remove the battery and reinstall the battery, recharge the battery. It then can unlocked! 2) Once you charge the battery, it has to be unlocked by repressing the button for 5 seconds and the light will flash to indicate that it's unlocked! 3) once you unlock the flashlight and in the first step the light is bright be sure not to hold the button too long or it will engage the Turbo mode ant the light will be much brighter, the flashlight's battery will get very hot and the battery will completely discharge and have to be recharged! 4) The instructions are vaguely written that doesn't explain how to charge and unlocked the battery step by step to prevent the flashlight from getting into the turbo mode! Once you unlock the flashlight step thru the different modes quickly until it's off! You can then lock the flashlight if you want or by holding down the button for 5 seconds and the flashlight will flash to indicate that it's locked. Most importantly stay away from the turbo mode! It's a fine flashlight!
