TUP2 MCT - 1200 lumens - Nitecore Singapore

Your phone flashlight drains the battery you need for navigation and emergency calls. This doesn't.

DEDICATED LIGHT SOURCE WHEN YOUR PHONE BATTERY MATTERS - When you're 10 miles into a hike and your phone hits 20% battery, the TUP2's 1,300mAh battery keeps your phone available for maps, photos, and emergency calls. Run the light on 300 lumens for two solid hours without touching your phone's charge.

GENUINELY POCKET-SIZED WITH SERIOUS OUTPUT - At 58g and 70mm length, this fits easily on your keychain. Press the button and get 1,200 lumens - the same maximum brightness as full-sized tactical lights that weigh three times as much.

THREE LIGHT COLORS FOR DIFFERENT CONDITIONS - Reading at camp after dark? Use 3000K warm light that's easier on your eyes than harsh cool white. Walking around your neighborhood? Switch to 4500K neutral for natural-looking illumination. Need maximum throw distance on night trails? Hit 6500K cool white. Each temperature uses dedicated LED cores optimized for that specific output.

RUNTIME THAT ACTUALLY LASTS THROUGH MULTI-DAY TRIPS - The 1,300mAh battery runs 271% longer than the original TUP. Use it two hours each evening on a camping weekend and you'll return home with battery remaining. On ULTRALOW mode (1 lumen), it runs for 190 hours continuously - that's nearly eight full days.

KNOW EXACTLY HOW MUCH POWER YOU HAVE LEFT - The OLED screen displays brightness level, remaining runtime, battery percentage, and current color temperature. When you're five miles into an evening hike at sunset, check the screen and see you have three hours of light available for getting back - no guessing about battery life.

METAL RING RATED TO 30KG FOR SECURE ATTACHMENT - The stainless steel ring pull withstands 30kg (66 pounds) of force - attach it to your keychain, backpack webbing, or belt loop and it stays secure through running, climbing, or daily wear. Works with standard carabiners and split rings.

QUICK START GUIDE

Out of the Box

Press the power button (circular icon near the screen). The light turns on at your last-used brightness and color temperature. Press again to cycle through brightness levels. You're using it in 5 seconds - no manual required.

Switching Color Temperatures

Press both buttons (Mode + Power) simultaneously to cycle through 3000K warm → 4500K neutral → 6500K cool white. The OLED screen shows which color you're using. The light remembers your selection between uses.

Direct TURBO Access

Long-press the Mode button for instant 1200 lumens - perfect when you drop your keys in a dark parking lot or need to check a distant trail marker quickly. No cycling through modes when seconds matter.

Lockout Mode (Prevents Pocket Activation)

Long-press the power button for 3 seconds to enable semi-lockout. The light won't turn on accidentally in your pocket (draining battery), but you retain instant TURBO access by pressing the Mode button. Set this once and forget about wasted battery.

WHAT MAKES THE TUP2 DIFFERENT?

Four Quad-Core LED Groups, Not Single LEDs

Each of the four LED groups contains dedicated cores for 3000K, 4500K, and 6500K output. This means 3000K warm genuinely provides comfortable reading light, while 6500K cool delivers maximum throw distance - not just white light with colored filters like cheaper options use.

Battery That Lasts Through Extended Trips

The 1,300mAh battery delivers 271% longer runtime than the original TUP. HIGH mode (300 lumens) runs for 2 hours continuously - enough to walk home from the train station every evening for two weeks before recharging. TURBO mode uses thermal management to prevent overheating during extended use.

OLED Screen Shows Critical Information

See brightness level, remaining runtime (in hours and minutes), battery percentage, and current color temperature at a glance. When you're miles from home at dusk, you can check and confirm you have enough battery to get back safely - no guessing about power levels.

Compact Size That Actually Fits Daily Carry

At 58g (same as three AA batteries) and 70mm length, this fits easily on your keychain without adding excessive bulk. The IP54 rating handles rain and dust, while the 2-meter impact rating survives drops onto concrete during daily use.

Here's what Nitecore changed from the original TUP

Bigger battery - 1,300mAh instead of 360mAh, giving you 271% longer runtime. Four quad-core LED groups that each pack all three color temperatures (not filters). An OLED screen that displays brightness, runtime, battery percentage, and color temperature.

Walk your dog in suburban neighborhoods? Use 300 lumens at 4500K neutral white - runs for two hours and lights the path clearly. Checking equipment in dark spaces? Drop to 80 lumens at MID mode for 7 hours 15 minutes of continuous light. Reading at camp after everyone's asleep? Use 1 lumen at 3000K warm - runs for 190 hours and won't disturb others.

The dual-button interface remembers your last settings. Configure it once to 4500K at HIGH mode, and it stays there until you decide to change it. Long-press for instant 1,200-lumen TURBO when you drop keys between car seats. Access 1-lumen ULTRALOW for extended power outages.

Built from aluminum alloy with IP54 protection against rain and dust. Survives 2-meter drops onto concrete. The efficient circuit maintains consistent brightness until the battery is nearly depleted - no gradual dimming that leaves you wondering if it's dying.

The built-in 1,300mAh battery recharges via standard USB-C in about 1 hour 20 minutes - use your phone charger, laptop, power bank, or car adapter. The stainless steel ring pull is rated to 30kg (66 pounds) for secure keychain attachment.

WHICH MODE FOR WHICH SITUATION?

TURBO (1200 lumens)

Finding dropped gear in complete darkness, reading distant trail markers, signaling for help. Maximum brightness with thermal management that steps down automatically when the body warms up - preventing overheating while maintaining usable output.

HIGH (300 lumens)

Evening dog walks in suburban neighborhoods, navigating dark parking garages, outdoor tasks after dark. This is the "default" mode most users stay on. Runs for 2 hours continuously - enough for two weeks of 30-minute evening walks before recharging.

MID (80 lumens)

Checking under dashboards, setting up camp, navigating dark hotel hallways. Enough light to work comfortably while conserving battery. Runs for 7 hours 15 minutes - perfect for extended tasks where you need consistent illumination.

LOW / ULTRALOW

Reading in a tent without disturbing others, checking your watch at night, navigating during extended power outages. ULTRALOW (1 lumen) runs for 190 hours - nearly eight full days of continuous use or weeks of intermittent use.

Color Temperature Guide

COLOR TEMP	BEST FOR	WHAT IT DOES
3000K Warm Light	Reading at camp, close-range tasks, comfortable lighting	Easier on your eyes than harsh cool white when working at close range. Use for reading, setting up camp after dark, or any situation where you want comfortable illumination without eye strain.
4500K Neutral White	Daily walking, general outdoor tasks, everyday use	Balanced, natural-looking light for everyday situations. This is the "default" setting most users prefer - works for 90% of situations without thinking about it. Provides good color rendering for identifying objects accurately.
6500K Cool White	Night hiking, maximum throw distance, alertness	Crisp, energizing light that throws the farthest beam of the three color options. Ideal for situations where you need maximum distance - spotting trail markers, identifying addresses from across parking lots, or staying alert during evening activities.

*NOTE

The TUP2 remembers both your last color temperature AND brightness level when you turn it back on. Set it once to your preferences and it stays there until you decide to change it. The OLED screen always shows your current settings.

Lockout Modes Explained

LOCKOUT TYPE	HOW TO ACTIVATE	BEST FOR
Semi-Lockout (Recommended)	Long-press power button for 3 seconds (OLED shows lockout indicator)	Daily pocket carry. Prevents accidental activation (and battery drain) while keeping instant TURBO access via mode button. Most users stay in this mode permanently for everyday carry.
Full Lockout	From semi-lockout, long-press power button again (OLED confirms full lockout)	Long-term storage or airline travel. Both buttons completely locked. You must unlock before the light will respond to any button press. Useful when you need absolute certainty the light won't activate.

*TIP

For everyday pocket carry, semi-lockout mode gives you the best balance: prevents accidental battery drain while keeping emergency TURBO access available. Unlock by long-pressing the power button again for 3 seconds.

Frequently asked questions

Can I replace the battery when it eventually wears out?

The 1,300mAh Li-ion battery is built-in for better water resistance and USB-C convenience.

When the battery eventually wears out from repeated charging cycles, Nitecore service centers can replace it. Yes, that's less convenient than swapping batteries yourself.

Most users prefer never buying disposable batteries again and always having USB-C charging available from any standard power source.

Why not just use my phone's flashlight instead?

When your phone hits 15% battery five miles into an evening hike, you need to save that power for navigation, emergency calls, and photos.

The TUP2's dedicated 1,300mAh battery runs for up to 190 hours on ULTRALOW mode (or 2 hours on HIGH mode) while your phone battery stays available for what phones do best.

Plus at 58g and 70mm length, it adds minimal bulk to your keychain - you'll forget it's there until you need it.

How do I know when the battery is getting low?

The OLED screen shows real-time battery percentage and remaining runtime in hours and minutes.

Check anytime to see exactly how much power you have left. When you're miles from home, you can confirm "2h 30min remaining" rather than guessing.

Drop to a lower brightness level to extend runtime if needed - the screen updates to show your new runtime estimate immediately.

Can I leave this unused for months without damaging the battery?

Yes, the TUP2 has approximately 12 months of standby time when fully charged.

Leave it in your car's glove box, emergency kit, or attached to your backup pack for months - it'll be ready when you need it.

For longest battery health, store it around 50-70% charged rather than completely full or empty if you won't use it for extended periods.

Does the brightness stay constant or gradually decrease?

The efficient circuit maintains consistent brightness until the battery is nearly depleted - no gradual dimming.

You get stable output throughout the runtime. When the battery finally gets low, the OLED screen warns you with the battery percentage so you can recharge or drop to a lower mode.

This regulated output means 300 lumens stays 300 lumens until the battery can't support it anymore - then it drops to the next stable level rather than slowly fading.

Will this work with gloves on?

Yes, both buttons are large enough to operate with gloves.

The power button and mode button are raised and easy to locate by feel. The dual-button design means you can access all functions without precision finger movements.

In cold weather or when wearing work gloves, you can still switch modes, activate TURBO, and check the OLED screen without removing your gloves.

Is this actually brighter than my phone's flashlight?

Yes, significantly brighter. The TUP2 outputs 1,200 lumens on TURBO mode.

Most phone flashlights output 40-100 lumens maximum. Even the TUP2's HIGH mode (300 lumens) is 3-7x brighter than your phone.

More importantly, the dedicated LED and reflector system throws light farther - 125 meters on TURBO versus maybe 10-15 meters from your phone. You'll see the difference immediately when trying to spot trail markers or identify addresses across parking lots.

What's the difference between this and $10 keychain lights?

Battery capacity, build quality, and features.

Budget keychain lights typically use 300-500mAh batteries (the TUP2 has 1,300mAh - 271% more capacity). They don't include OLED displays showing remaining runtime, multiple color temperatures, or proper thermal management.

Construction matters too:

Aluminum alloy body versus plastic housings that crack
30kg-rated ring pull versus weak attachment points that fail
IP54 water resistance versus no water protection
Regulated brightness versus gradual dimming

Cheaper lights work fine for finding your keyhole. The TUP2 handles actual outdoor use and emergency situations where reliability matters.

Is 58g actually light enough for daily keychain carry?

At 58g (same weight as three AA batteries or about ten quarters), the TUP2 is light enough for daily keychain carry - most users forget it's there until they need it.

However, if you already carry a heavy keychain with multiple keys and accessories, adding 58g might tip it into "too heavy" territory.

In that case, consider using the included key clasp to attach it to your backpack, belt loop, or jacket pocket instead of your main keychain.

Can I use this while it's charging?

Yes, the TUP2 supports use-while-charging.

Connect any USB-C cable (from phone charger, laptop, power bank) and you can use the light at any brightness level while it charges.

This is particularly useful during extended power outages or when setting up camp - you can have the light running while it charges from a portable power bank, essentially giving you unlimited runtime as long as power is available.
