MANKER Flashlight Tube - 18650 Battery Tube E14 Cree XP-G3 / Nichia 219B / Nichia 219C

Fits perfectly and light works fine with the 18650s.

Doesn't work right. Flashlight works fine with stock barrel. This longer one requires you to NOT screw the tail-cap all the way on. Almost as if it's the wrong length.

The Manker Flashlight Tube 18650 Battery Tube For my Manker E14 Nichia 219C 1600 Lumen flashlight is of the same high quality as the flashlight. The material is high quality aircraft grade aluminum. The tubes form, fit, and finish are exceptional. Looks great on the flashlight, and will take any IMR High Drain 18650 Lithium Ion battery. There is a correct way to install the tube. If you thread it in the wrong way, the flashlight won’t turn on. Just simply unthread it, and thread the tube correctly into the head of the flashlight and it will work just fine. You can also install the titanium coated deep pocket clip onto the extension tube, and it also provide as more of a ( Handle ) to hold onto. I will use the extension tube for longer run times that I need for camping, hunting, car repair, flying my DJI Mavic Pro at night, night walks with my wife, hanging out at night at the family bon fires and so on. I am glad that I purchased this extension tube when I purchased my Manker E14. Great product and gives you already versatile flashlight even more versatility. I highly recommend to anyone that already own the Manker E14, or is going to purchase one. You will be glad you did.

I had read that these tubes don't come with o-rings, but I'm glad to say this one did.IMO an essential upgrade for the Manker E14 / Astrolux S41 (exactly the same flashlight, just different branding). The copper head on the E14/S41 gets hot quickly with high and turbo modes so you can't really grip it there, then the tail of the flashlight is too short to get a good grip. And really it's too wide and heavy to get any real EDC advantage from the shorter stock length. With this tube, the size is perfect, well proportioned.And using an 18650 battery gives you more power than a 18350/16340, and if you have other flashlights you're likely to already have some 18650s but maybe not some 18350s or 16340s laying around...Note - this is not an extension tube, it is a longer replacement tube. You put the head and tailcap onto this one and figure out something else to do with the original stock tube. Be creative.

Fits and works perfect for my flashlight to add a 18650 full size battery for longer life.

My $40 flashlight is now a $55 flashlight. But it is awesome.

Fits good long battey life.

Works for the Astrolux s41 Too.
