Nitecore Digicharger D4EU Four Bay Battery Charger

NEBO Davinci 8000 Rechargeable LED Torch
Neat Unit

I'm very happy with this device. Initially I thought the slider mechanism felt a bit flimsy, but I have now worked through my stock of old batteries and everything works well. A bonus for me is that it will also test button cells, which my previous tested did not. Overall, a good piece of kit at a good price.

Amazing little torch

Even through I’d check the dimensions the torch was much smaller than I expected when it arrived. It feels great in hand, very robust and machined to a high standard. Various modes to choose from and when on high it is amazing how much light this tiny torch produces. Run time seems fine so far also. If in doubt, buy it and you won’t regret. As a side note, Torch Direct…. Quick and efficient service. Full marks :)

Nice greenish colour body and parts.

The tiny LED head is like a fibre optic head i had for a maglite. Great for inspection inside small spaces. Very useful multifunction set.

Great little pocketful. Bright green laser pointer. Useful 365 UV which shows extra details on IDs. Lastly a lovely white light with 3 levels of brightness. Magnetic charger.
Recommended.

Simon
Olight Arkfeld Pro Rechargeable LED Torch, White Light, 365 nm UV & Green Laser

Very bright for its size as a marker.
It’s not a torch.
The MI is the “Military” version.
It flashes IR or green and can be solid IR or green.
The green is very bright and visible.
The IR is 950nm and if you have the right thing also very bright. iPhone can just about see it.

Simon
Nitecore NU05 MI Mini Rechargeable LED Signal Light
Illuminating

On the lowest level the light is a little green. Much better at the other illumination level. Takes a while to charge through the USB interface. The battery lasts well. Good for walking the dog at night around poorly illuminated roads.

What do I think of my Nitecore EDC27 Slim Rechargeable LED Torch. Ace!

I bought my Nitecore EDC27 Slim Rechargeable LED Torch quite a while ago. It has taken me a while to get to know what this amazing bit of kit can do! Well it's a torch! yes but's it's more than that! Yes I know it can be useful when taking the rubbish out to find the item you dropped out of the bag blah blah. Now I am a bit older & a bit more savvy, I have bought some work trousers with many pockets in them for all the things it seems you need to carry around in life. In the long pocket next to my Biro pen & propelling pencil is my torch with it's lanyard attached. So I always have it with me. I have found it useful in many ways, one of which was when I broke down in my very old car, I knew I would have to wait a long time for recovery, so I looked up on my phone what to do on my phone, while changing the light settings on my torch when I needed to find the problem. I had a Hi Vis jacket on, but i was in the middle of nowhere. So I used the flashing setting when the van got near so he could find me that bit easier. Yes it's still a torch you say, yes, another time I was walking down an alleyway on a short cut home, when out popped some unwanted people who I was unsure of, as I got near them they asked if they could use my phone, with that I selected the brightest mode, shone it in their faces to temporarily blind them & ran as fast as I could. So for me it's more than a torch. Something I hardly ever leave home without, useful when you lift drops his keys in an unlit pub car park in the rain on a very cold night.
Other stuff. I find the small screen that displays various different things invaluable. Especially if you are going out on a cold winters night, has the torch got enough of a charge, well you can check that, the slimness of it also comes in handy when in your best bib & tucker (a suit) you can easily hide it in your inside pocket. How long does it last, a long time, I have put a bit of string on a label for when I charge it, I charge it so infrequently I nearly forget which one it is, I do use it a lot! Cost, yes it's expensive, but you get what you pay for, very good quality. I really recommend it! Mister XR
