NitecoreTube v2.0 Keychain Flashlight, 55 Lumen USB Rechargeable Ultra Lightweight Compact (Olive)

I love these and bought a bunch to give as presents. I have a version 1.0 for years I carry with me everywhere. The battery lasts a long time and charges quickly. Compact, lightweight, durable, and bright. Wish it was USB-C, but the connector would be much bigger, so that might be why they are sticking with MicroUSB.

I bought this to add to my keychain. It is very lightweight, and the key loop on the back looks sturdy. The light has several brightness settings and a lockout feature to prevent accidental use. I ran the lite down to no output and charged it up using a charge meter. Nothing on the packaging or the website says how big the battery is. I measured the battery capacity at 156mAh. I didn't put a timer on how long it stayed on while running it down, but the packaging says 58 hours of run-time. From what I experienced, that seems 100% plausible. Excellent light for $9.99. I love that there is not a button cell battery to mess with replacing.

This is on my keychain for when 'someone' leaves the porchlight off and I can't see to get my key in the lock. It's not so bright it blinds you but it's not dim and useless; it's the perfect brightness for what I need. Bonus: the battery lasts quite a while too.

My application was a keyring light to put keys in a door at night. It does that well, but I opted for a more costly version since it was rechargeable, and had 55 lumens instead of the paltry 12 lumens of non-rechargeable ones.+Pros: It's small and light; it's bright enough for keys; it's rechargeable; it comes with two keyring sizes.Cons: It has outdated micro-USB charging port; it has no visible indication of remaining charge; it has cold, soulless version of white light.Improvements: a) Change to USB-c, please b) have visual indicator of charge remaining c) make it water resistant

I've used a few different EDC keychain flashlights, and this Nitecore Tube v2 is my preference for a balance between light weight, ease of use, (can find the on/off button easily), brightness levels, and price.I like that I can retrieve this from my pocket and with two clicks can have plenty of illumination for most all my needs. I also like the ease of switching to the lockoff feature to prevent accidental pocket/whatever power on, even though I don't use this feature in my everyday use.The fact that the first click to power on enables very low illumination is great - I've used this a couple of times - once helping someone find their dropped glasses in a dark movie theater. The first click is low intensity to not bother anyone, yet still bright enough to be useful.I did once experience an issue with my Nitecore Tube v2. I contacted the dealer through Amazon, and within a couple of days my issue was resolved to my complete satisfaction. They do stand behind their products. I wouldn't hesitate to purchase from them in the future.

This compact little two-setting light is just right for my needs. I use the low setting for getting around the house after we have all gone to bed, and it is plenty bright for that purpose. The high setting is surprisingly bright, and I just use that occasionally when I need to get a better look at something. I love the fact that it is rechargeable via USB, as I was getting tired of replacing all those expensive little button batteries in my previous light. This light is small and light enough to just drop into your pocket if you are one of those guys (like me) who likes to carry a flashlight pretty much everywhere. (There is a simple procedure that allows you to disable the button so it won't accidentally activate in your pocket).I do have to warn you not to look directly into the LED, especially while it is on the high setting. It is extremely bright at close range and it will blind you and have you seeing spots for quite awhile. Take my advice: Don't look directly at the sun, and don't look directly at the LED.

This is rechargeable via USB B. They are very light they have a bright and a dim setting and it all operates with one simple button. I have given a ton of these away as gifts they're very bright for their size.

This is a good little keychain flashlight. It has two intensities. Compact and lightweight . Rechargeable, which is a plus.However the advertising on the Amazon site led me to believe I was ordering one that has a pivoting head.I will keep this one since it is good to light your way in a dark room. It is probably better than nothing if you are outdoors walking in a dark or dimly lit street or if you are out in the woods with no other kind of light but if you are riding a bike and need to see several feet in front of you this would not cut the mustard. . Of course I have not tried it in such a manner.I have not used the light on a long term basis and am not sure how long lasting and rugged it is.I will update as I am able to.
