The keychain light that's actually worth carrying every day.
ALWAYS READY WHEN YOU NEED IT — Advanced Power Cut-Off (APC) technology keeps parasitic drain to just 1μA, so the TUBE V2.0 holds its charge for up to 365 days on standby. Clip it to your keys, forget about it, and it's ready the moment you need light.
DIAL IN EXACTLY THE RIGHT AMOUNT OF LIGHT — The infinitely variable brightness system lets you smoothly adjust from a soft glow to full power. Set it low to read a menu in a dark restaurant, or crank it up to light a path back to your car.
CHARGE IT FROM ANY POWER SOURCE — Plug into your laptop, power bank, or phone charger. A quick top-up keeps this light ready to go, and the built-in indicator lets you know when charging is complete.
BUILT-IN PROTECTION FOR THE BATTERY — The intelligent charging circuit includes overcharge protection, over-discharge protection, and short circuit protection — safeguards that keep the internal Li-ion cell healthy over the long haul.
58 HOURS ON A SINGLE CHARGE — At the 1-lumen low setting, you'll get over two full days of continuous light from the built-in 125mAh Li-ion battery. At max output, expect 1 hour and 15 minutes of solid brightness.
WHAT MAKES THE TUBE V2.0 AN UPGRADE OVER THE ORIGINAL?
22% Brighter Output
The V2.0 pushes 22% more brightness than the original's 45-lumen output — enough to clearly light up a room during a power outage or illuminate a trail junction at night.
25% Faster Charging
Charges 25% quicker than the original, which took 2 hours. One cable for your phone, laptop, and keychain light.
21% Longer Runtime
Over two full days of continuous light at low — a 21% improvement over the original's 48 hours, from a device that weighs under 10 grams.
IP65 Dust & Water Protection
Sealed against dust ingress and protected from water jets in any direction. Get caught in a downpour, rinse it off under the tap — the TUBE V2.0 keeps working.
A 100-degree flood beam from something smaller than your thumb.
Most keychain lights produce a tight, narrow spot. The TUBE V2.0 throws a wide 100° flood that illuminates your peripheral vision — perfect for lighting up a tent, finding a keyhole, or navigating a dark stairwell.
The high-performance LED pushes 156 candela at max output, reaching 25 meters. That's enough throw to light up a campsite or find your car in a parking garage.
The APC (Advanced Power Cut-Off) system reduces standby drain to just 1μA — effectively zero. Charge it up, toss it on your keychain, and it'll be ready to fire up even a full year later. That's the kind of reliability you want from an emergency backup light.
9.6 grams. You'll forget it's there until you need it.
At 56.5mm long and just 8mm thin, the TUBE V2.0 tucks in alongside your keys and adds virtually zero bulk. The polycarbonate body is the same high-strength material used in riot gear, sporting helmets, and aircraft components — it absorbs impact rather than shattering.
The stainless steel key ring connector handles up to 35kg (77 lbs) of weight, so it stays securely attached to your keychain, bag, or zipper pull through daily use and the occasional snag.
Impact resistance rated to 1 meter, so an accidental drop isn't going to take it out of commission.
One button. Five ways to use it.
LOW MODE — Single press turns on at 1 lumen. Great for reading, checking a map, or finding something in your bag at night. Press again after 3 seconds to turn off.
HIGH MODE — Double press jumps straight to 55 lumens. Instant full brightness when you need it fast.
MOMENTARY — Press and hold for over 1 second for a quick burst at full brightness. Release and it shuts off. Handy for a fast peek into a dark space.
VARIABLE BRIGHTNESS — Short press, then long press to smoothly ramp through the full brightness range. Release when you hit the level you want.
LOCKOUT MODE — With the light on, hold the button for 3 seconds until the LED flashes. This prevents accidental activation in your pocket or bag. Hold again for 3 seconds to unlock.
Smart battery protection with built-in charging.
The integrated USB-C port sits on the side of the body — plug into any USB power source to charge. The blue indicator on the power button glows steady during charging and goes dark when the battery hits 100%.
You can keep using the TUBE V2.0 while it's plugged in — handy if you need light and a charge at the same time.
When the output starts to dim or the light becomes unresponsive, it's time to recharge. Nitecore recommends topping up every 3 months if you're not using it regularly, just to keep the Li-ion cell healthy.
9 colors. Pick the one that fits your style.
Available in Azure, Jacinth, Orange, Lemon, Green, Black, Blue, Olive, and Transparent. The transparent option shows off the internals — a nice touch if you appreciate the engineering inside.
Every color uses the same high-strength polycarbonate body with excellent elastic coefficient, giving you both impact toughness and a clean finish that holds up over time.

FREQUENTLY ASKED QUESTIONS
Can I replace the battery?
The Li-ion battery is built into the unit and is not user-replaceable. With proper care — including a top-up charge every 3 months during extended storage — the integrated cell provides reliable long-term performance.
Is it waterproof enough for rain?
The TUBE V2.0 carries an IP65 rating, which means it's fully sealed against dust and protected from water jets in any direction. It'll handle rain, splashes, and a rinse under the tap. It's not rated for submersion, so avoid dropping it in a pool or stream.
Does it remember my last brightness setting?
The Infinitely Variable Brightness mode does not have mode memory. Each time you activate it, you'll ramp through the brightness range from scratch. The fixed LOW (1 lumen) and HIGH (55 lumen) modes are always available via single press and double press shortcuts.
Will the light turn on accidentally in my pocket?
The built-in Lockout Mode prevents accidental activation. With the light on, hold the button for 3 seconds until the LED flashes to engage lockout. Hold again for 3 seconds to unlock. The lockout also disengages automatically when you plug in a USB-C cable to charge.
How do I know when the battery is low?
The output will start to dim or the light may become unresponsive when the battery is running low. During charging, the blue indicator on the power button stays on steady, then turns off when charging is complete.
