SdeNow Mini Flashlight Keychain EDC 200 lumens USB Micro Rechargeable Pocket Waterproof Flashlight

I've had this flashlight on my key ring for years and for those times when you just need a flashlight to find something or see something, It's been great. Any bigger than this and you're Joe Toolbelt. I want to be able to put my keys in my pocket and I already have a car keyfob and an Airtag, so enough. There are even smaller flashlights, but then you're dealing with stacks of obscure hearing aid batteries instead of rechargeable. The one minor drawback of this flashlight is that it uses the antiquated Micro USB to charge, but unless I use it steadily for hours (never) I charge this flashlight maybe once a month.

I've looked at a LOT of mini-flashlights, and this is by far the best for EDC/every day carry. I had one that took a battery and was twice as long hanging from my clip, longer than everything I was carrying. As you can see from the photo, this one matches the other items. And better still, it has more lumens than most minis, definitely more than what I've been using. And no batteries! It is easy to recharge with the USB cord supplied. It is easy to operate, just a simple twist and you have a lot of light from a little device. Maybe I'm a bit OCD, but like others I want compact EDC items. By the way, I got the clip, whistle, pill container, and pry bar from Amazon; the P38 from the Army. Because everything's small, only I know I'm carrying them. If you're into EDC, this is a must, especially if you like to keep your items in an Altoids box. Definitely an improvement.

I have used this flash since 2020, and it worked reliably until about two years ago, when it started to show strange behavior. When fully tightened, the light goes off. To turn it on, I needed to loosen it slightly. Though it was on, it was flickering and the head was wobbly. I did everything that came to my mind related to the connection of the battery and the head, and nothing worked. Until eventually, I figured out that the LED unit can be unscrewed from inside the head using needle nose tweezers. The LED unit uses brass screws, with very loose tolerance. When the LED unit is tightened inside the aluminum casing, the threads are fully engaged. When the battery unit pushes from behind, it forces the male threads of the LED unit to move away from the female threads, and the connection is lost. This initially was not an issue since it's only over time that the oxidation of the aluminum builds up. After a long time, there should be significant mechanical push to allow current to pass though the aluminum oxide layer and brass.The fix is to unscrew the LED unit using needle nose tweezers. Then apply a bit of soldering paste into the far end of the aluminum housing where the threads eventually tighten. Then tighten the LED unit back in and you're good to go!

My previous AAA key-chain light quit working after a few years and I wanted a key-chain light again. I began searching on Amazon for key-chain flashlights, concentrating on lumens. I found some really bright lights, but they were all over 4 inches long, or 2 inches long but over $40. I didn't want to get a 4 or 5 inch flashlight because it would be longer and much heavier than my whole key-chain. I concluded that the physical size, and the price was more important than the exact amount of light output. Of the remaining available lights, I really liked this red SdeNow mini flashlight best.It arrived in a nice metal box containing the mini-flashlight with a handy split-ring attached, a USB-mini cable, and a manual.The battery is a 4-volt 10180 rechargeable lithium-ion battery (10mm diameter, 18mm long) which is built-in. The flashlight is built around this size of battery, hence its size.The flashlight has 2 o-rings, which provide IPX-7 water resistance (IPX7 = water immersion up to 1 meter depth). I found the flashlight to be extremely difficult to turn on with one hand because of the turning resistance from the 2 o-rings. However, with the flashlight attached on my keychain, it was possible to turn it on and off with one hand. With 2 hands, it's easy. I think it would be extremely unlikely for this flashlight to be turned on accidentally, because of its significant turning resistance.The red flashlight is probably anodized aluminum. (Anodized titanium doesn't come in that red color.) The black model might be titanium, but whether the metal is aluminum or titanium doesn't really matter to a flashlight. This flash-light is very strongly built.The Cree website says the XPG R5 'bulb' is in the 139-148 luminous flux group. The light is brilliant white in color and the brightness is excellent for a flashlight of this key-chain-convenient size. As I learned long ago with digital cameras, whether or not your camera is with you, at some random time, depends on its physical size. The small size of this flashlight means it will always be with me on my key-chain.

A small flashlight that is easy to carry on a keychain. It is small as in you can hold it between 2 fingers. You twist it and the light comes on, surprisingly bright. Great for when you need a flashlight but don't want to carry around a Maglite that security guards use as a riot baton.

Cute and handy, but died within a week of light use
