Olight makes the lights discussed here. Olight specs and regular prices come from its US product pages and user manuals as of September 2026. Airline rules come from the FAA and TSA. The daily-use plans, charge counts and weight sums below are calculations from those published numbers, not measurements.
⚡ TL;DR
For a long trip, the best travel flashlight setup is two small lights, not one big one. A 22 g keychain light rides in your pocket for keyholes and bag searches, and a 54 g headlamp-flashlight handles dark streets, dorm rooms and outages. The Olight i1R 2 Pro and Perun 3 Mini together weigh 76 g before the headband and cost $86.98.
Every gram in a travel bag has to earn its place, so most people skip the light or pack a heavy torch that never leaves the suitcase. Then the hostel lights go out, the night bus drops you on an unlit road, or the hotel loses power, and your phone becomes the flashlight you need for maps and tickets. This guide shows which light covers which moment, what each gram buys, how to charge abroad and what the FAA and TSA allow.
This table is the travel flashlight packing list: each job, the type of light that fits it, the minimum spec that matters and the Olight model that meets it.
| Use | Recommended type | Key spec floor | Recommended model |
|---|---|---|---|
| Keyholes, bag searches, room numbers | Keychain light with a low mode | 5 lumen low, under 25 g | Olight i1R 2 Pro (5 lm Low, 22 g) |
| Walk back from a late train or bus | Headlamp-flashlight with a focused beam | 100 lumens for 4 hours or more | Olight Perun 3 Mini (100 lm Med, 4.5 h) |
| Dorm bunks and shared rooms | Headlamp with red light | Red mode near 5 lumens | Perun 3 Mini (red Low 5 lm, 19 h) |
| Hotel power outage | Hands-free light with a long low mode | 10 lumens for a full day | Perun 3 Mini (Low 10 lm, 30 h) |
| One light only, clipped to a strap | Clip light with red, magnet and USB-C | Clip, magnet, red mode | Olight Oclip 2 Pro (75.5 g) |
| Lightest backup in a daypack | Magnetic mini light | Under 20 g, instant on | Olight imini 2 (19.5 g, 50 lm) |
| Keeping the headlamp charged | Spare magnetic cable | The cable the light's page lists | MCC Magnetic USB Charging Cable ($9.99) |

Quick Answer: A Keychain Light and a Headlamp, About 76 Grams
Pack two lights: a keychain light that never leaves your pocket and a small headlamp-flashlight in your daypack. On Olight's ratings, the i1R 2 Pro (22 g) and Perun 3 Mini (54 g) weigh 76 g together before the headband. They charge in two different ways, so one lost cable or one dead battery never leaves you in the dark.
One light is enough for a short city trip with a hotel outlet every night. If you want only one, the Oclip 2 Pro is the strongest single choice: it clips to a strap, sticks to steel, has red light and charges by USB-C or MCC. The trades: its manual forbids immersion and warns ICD and pacemaker users about close contact. Olight's range of pocket-size EDC flashlights shows other shapes if neither fits your carry style.
What Is the Best Flashlight for Travel?
The best flashlight for travel is light enough to carry daily, rechargeable from a common USB charger, bright enough for an unlit street and dim enough for a dorm. For most long trips that means a headlamp-flashlight around 50 to 60 g with a red mode, plus a keychain backup. On those checks the Perun 3 Mini fits best among Olight's current lights.
Use five checks on any travel flashlight:
- Under about 60 g with battery. Heavier lights stay in the suitcase.
- A low mode of 10 lumens or less. Dim modes get the most use.
- A red mode for dorms and night vision.
- Charging from a USB charger you already carry.
- A lockout, so it can't switch on in a bag.
The Olight Perun 3 Mini headlamp ($64.99, regular price, September 2026, default Orange CW Standard listing) passes all five. Olight rates the cool white version at 1,250 lumens, 6,000 candela, 155 m, IPX8 and 54 g with battery. Modes: Turbo 1,250~350 lumens for 2 + 60 minutes, High 500~350 lumens for 2 + 75 minutes, Med 100 lumens for 4.5 hours, Low 10 lumens for 30 hours, Moon 2 lumens for 10 days, red 45 lumens for 150 minutes or 5 lumens for 19 hours. The same page lists a High CRI NW version (920 lumens, 133 m) and a Premium Edition with a charging case.
This pick differs from our second flashlight guide and our best headlamps roundup, which name the full-size Perun 3 for home and camp. The reason is weight. The Perun 3 weighs 150 g; the Mini does the travel jobs at 54 g, 36% of that, in exchange for 100 lumens for 4.5 hours instead of 120 lumens for 25 hours.
The limits: the 650 mAh battery needs a recharge in long outages, it charges only by magnetic cable unless you add the case, and its 0 to 40 °C working range rules out winter treks. For cold trips, our rechargeable headlamp comparison explains when AAA lithium cells do better.
Seven Moments a Travel Flashlight Actually Gets Used
On a long trip a travel flashlight mostly works in short, dim, close-range moments: a keyhole, a bag, a dark room, a bunk number, the last stretch from a station. Bright beams matter only on unlit streets and during outages. Plan the kit around the dim jobs, and keep one bright mode for the walk home.
This table lists seven travel moments with the light level, runtime and water rating each needs, and the kit light that covers it.
| Moment | Light level | Runtime per use | Water rating that matters | Kit light and mode |
|---|---|---|---|---|
| Keyhole, locker, bag search | 5 lm | Seconds to 2 min | Rain | i1R 2 Pro Low |
| Dorm bunk, shared room | Red, about 5 lm | 5 to 20 min | None | Perun 3 Mini red Low |
| Night bathroom trip in a strange room | 1 to 2 lm | 2 to 5 min | None | Perun 3 Mini Moon |
| Walk from a late train or bus | 100 lm or more | 10 to 30 min | Rain | Perun 3 Mini Med |
| Hotel power outage | 10 lm | Hours | None | Perun 3 Mini Low on the headband |
| Night train, ferry, overnight bus | Red or Moon | Minutes | Deck spray | Perun 3 Mini red Low (IPX8) |
| Late check-in, map, luggage tag | 10 to 180 lm | 1 to 5 min | Rain | i1R 2 Pro High or Perun 3 Mini Low |
Five of the seven moments need 10 lumens or less, so the low modes decide how long a charge lasts. Only the walk home and the outage need real output or long runtime. The Perun 3 Mini carries those; the i1R 2 Pro covers the rest from your pocket.
The Olight i1R 2 Pro keychain light ($21.99, regular price, September 2026) has High at 180 lumens for 23 minutes and Low at 5 lumens for 12 hours, 580 candela, 48 m, IPX8 and 22 g. Its built-in 130 mAh cell charges through a USB-C port, and its manual counts runtime until brightness falls to 50%. For what a light this size can do, see our keychain flashlight guide.
Backpacking Light Weight: What Each Gram of Travel Light Buys
A two-light travel kit weighs 76 g on Olight's ratings: 22 g for the i1R 2 Pro and 54 g for the Perun 3 Mini, before the headband. A one-light kit built on the Oclip 2 Pro weighs 75.5 g. The weights are nearly equal, so the choice turns on backup and water rating, not grams. The charging case is the heavy add-on.
This table compares five ways to build a travel light kit by weight, regular price and trade-off.
| Kit | Weight (Olight ratings) | Regular price, September 2026 | Trade-off |
|---|---|---|---|
| i1R 2 Pro only | 22 g | $21.99 | Always on you; no red, no headband |
| Perun 3 Mini only | 54 g plus headband | $64.99 | Red and headband; no backup if the cable is lost |
| i1R 2 Pro + Perun 3 Mini | 76 g plus headband | $86.98 | Two lights, two charging paths |
| Oclip 2 Pro only | 75.5 g | $54.99 | Clip, magnets, USB-C; no immersion, no backup |
| imini 2 + Perun 3 Mini | 73.5 g plus headband | $84.98 | Lightest pair; imini 2 is 50 lm, IPX6 |
Olight does not publish the weight of the Perun 3 Mini headband or the MCC cable. Adding a $9.99 spare cable to the pair makes $96.97.
The charging case needs its own math. Plan on 142 g for the case alone: the Premium manual prints that weight in the charger's spec column, and the standalone case page lists the same figure. Olight says the case "can fully charge the Perun 3 Mini up to 5 times," so each extra charge costs 142 ÷ 5 = 28.4 g. Carry it only when outlets are rare, such as a trek between huts; it can also charge a phone.
The same case is sold alone as the Charging Case for Baton 4 ($39.99, regular price, September 2026). Olight says it "supports storing and charging the S1R II, Perun Mini, Perun 2 Mini and Perun 3 Mini," so a Standard Perun 3 Mini plus the case costs $104.98.
Hostels and Shared Rooms: Light That Doesn't Wake Anyone
In a hostel dorm, use red light at about 5 lumens, aimed at your hands and bag, never at the room. Dim red light keeps your eyes adjusted to the dark and spills less onto nearby bunks. The Perun 3 Mini's red Low gives 5 lumens for 19 hours, and its Moon mode gives 2 lumens of white.
The National Park Service's article on dark adaptation and red flashlights says night vision takes 20 to 40 minutes to build and that "a dim red light is best for maximizing after-dark eye behavior." NSF NOIRLab adds that red light preserves night vision "better than other colors but is still bright enough to allow people to see what they are doing in a dark environment."
A dorm routine using the Perun 3 Mini's documented controls:
- Before lights-out, put the light on the headband and hang it on the bunk post.
- For red light, the manual says, "When the flashlight is off, double press the button to access red light mode." Press and hold cycles Low, High and SOS; release on Low.
- For a bathroom trip, use Moon: "press and hold the button for over one second to access Moonlight."
- Reading in bed, double-press and hold while on to set Auto Shut-Off; one flash means 3 minutes, two mean 9.
- Before the locker, hold the button about 2 seconds from off to lock it.
Tip: Tilt the headlamp down before you switch on, so the beam lands on your hands, not the bunk across from you.
The i1R 2 Pro has no red mode, and its twist switch comes on at 5 lumens of white. That is fine for a locker, not for a dark dorm.
Night Trains, Ferries and Airports: The Transit Light
In transit, the light you use most is the one you can reach without opening a bag. Keep the i1R 2 Pro on your keys or zipper pull for tickets and seat numbers, and the Perun 3 Mini where you can grab it. On overnight trains and ferries, red or Moon is enough. For the walk off a late bus, switch to Med.
- Night trains and buses. Red Low finds a cable or water bottle without lighting the carriage. The magnetic tailcap sticks to steel if the berth has any; the clip grips a bag strap if not.
- Ferries. The Perun 3 Mini and i1R 2 Pro are rated IPX8, the imini 2 IPX6 and the Oclip 2 Pro IP66. The Oclip 2 manual says: "Do not immerse the product in water or other liquids, as it will damage the product."
- Airports. A dropped earbud needs only the i1R 2 Pro's 180 lumen High.
- The walk from the station. Med gives 100 lumens for 4.5 hours. Double press for Turbo at 1,250 lumens to check a dark block; it steps down to 350 lumens after 2 minutes.
Safety note: Don't shine these lights at drivers or other people. The i1R 2 Pro user manual warns: "DO NOT shine the light directly into human eyes. This may cause temporary blindness, or permanent damage to the eyes."
Hotel Power Outage: The First Ten Minutes
When a hotel loses power, reach for a flashlight, not a candle, and unplug your chargers. The American Red Cross power outage checklist says, "Use flashlights, not candles." On the Perun 3 Mini's rating, a headlamp on Low at 10 lumens lights a room for 30 hours and keeps both hands free.
- Light first. Headband on, Low (10 lm). Save Med for the stairs.
- Unplug chargers. Ready.gov's power outage guidance says, "Turn off or disconnect appliances, equipment, or electronics. Power may return with momentary surges or spikes that can cause damage."
- Save the phone for calls, maps and hotel messages.
- Keep the keychain light as backup. The i1R 2 Pro's Low runs 12 hours by its 50% rule.
- Recharge when power returns. The Perun 3 Mini manual lists "<90 mins" to full from a USB-A 5 V 1 A source.
The Premium case doubles as a bedside base: its manual says the flashlight "can stay lit during charging with the lid open."
Charging Abroad: Plugs, Voltage and Which Cable Each Light Needs
Every light in this kit charges from 5 V USB, so foreign wall voltage never reaches the light itself. What changes is the plug and the port. Check the input rating printed on your USB wall charger, then count the USB-A and USB-C ports the kit needs. Three of the five charging paths below end in a USB-A plug.
The wall charger is the part that meets foreign power. Apple's iPhone safety information, for example, lists its 5W USB power adapter at "Line voltage: 100 to 240 V" and "Output power: 5V/1A." That output matches the "USB-A 5V 1A" input the Perun 3 Mini manual lists for its MCC cable. Read your own charger's label before you leave.
This table is a port audit: the connector at each light, the plug at the charger end, the full-charge time and the fallback if the cable goes missing.
| Light | Connector at the light | Plug at the charger end | Full charge (user manual) | If the cable is lost |
|---|---|---|---|---|
| i1R 2 Pro | USB-C port under the tailcap | USB-A (USB A-C cable) | Up to 100 min | Any USB-A to USB-C cable fits the port |
| Perun 3 Mini | MCC magnetic contact | USB-A (MCC 1A, 5 V 1 A) | Under 90 min | MCC cable or the charging case only |
| Perun 3 Mini charging case | USB-C port | Your USB-C cable | 2.5 h from a 5 V 2 A (10 W) source | Any USB-C cable |
| Oclip 2 Pro | USB-C port or MCC tail | Your cable | 1 h 30 min USB-C, 1 h 15 min MCC | USB-C or MCC cable |
| imini 2 | USB plug in the magnetic cap | USB-A | About 60 min | No cable needed |
Three paths end in USB-A, so if your only charger is a USB-C phone brick, pack one with a USB-A port too. And the Perun 3 Mini is the only light with no cable fallback.
The MCC Magnetic USB Charging Cable ($9.99, regular price, September 2026, NEW MCC 1A option) fixes that. The Perun 3 Mini page names "MCC 1A Magnetic Charging Cable" as its charging type. The cable page's compatibility list names the Perun Mini and Perun 2 Mini but not yet the Perun 3 Mini, so go by the light's page.
The Oclip 2 manual says, "Only use a USB-C charging cable, an OLIGHT MCC Charging Cable, or the dedicated Charging Dock to charge the product to avoid damage," and that it "cannot be charged in environments below 0°C or above 45°C."
A 30-Day Charging Plan for a Multi-Leg Trip
On a sample daily profile, each light in the two-light kit uses a little over 9% of a full charge per day. That is about 10.6 days per charge, so a 30-day trip needs two top-ups per light after leaving full, and each day of use costs about 8 to 10 minutes of charging. These figures are based on Olight's rated runtimes, not measured.
The profile is an editorial example, not a survey; swap in your own minutes. Each mode's share is minutes used divided by rated runtime in minutes. This table shows the arithmetic, days per charge, charges used in 30 days and wall time per day of use.
| Light and daily profile | Share of a charge per day | Days per charge | Charges in 30 days | Charging time per day |
|---|---|---|---|---|
| Perun 3 Mini: 20 min red Low (20 ÷ 1,140 = 1.75%), 20 min Med (20 ÷ 270 = 7.41%), 30 min Moon (30 ÷ 14,400 = 0.21%) | 9.37% | 10.7 | 2.8 | 9.37% × 90 min = 8.4 min |
| i1R 2 Pro: 2 min High (2 ÷ 23 = 8.70%), 5 min Low (5 ÷ 720 = 0.69%) | 9.39% | 10.6 | 2.8 | 9.39% × 100 min = 9.4 min |
| Oclip 2 Pro alone: 20 min red High (20 ÷ 240 = 8.33%), 20 min flood Medium (20 ÷ 225 = 8.89%), 30 min Moon (30 ÷ 8,640 = 0.35%) | 17.57% | 5.7 | 5.3 | 17.57% × 90 min = 15.8 min |
| imini 2: 3 min at 50 lm (3 ÷ 60) | 5.00% | 20 | 1.5 | 5% × 60 min = 3 min |
Days per charge is 100 divided by the daily share; charges in 30 days is 30 times the share; charging time scales the rated full charge linearly, as a rough guide.
- Top up whenever there is an outlet, even for 20 minutes. Battery University's lithium-ion charging guide says "a high current charge will, however, quickly fill the battery to about 70 percent," and that "Li-ion does not need to be fully charged."
- Before a leg with no outlets, count days. The two-light kit covers about 10 days from full; the Oclip 2 Pro alone covers about 5.
- For longer gaps, bring the case. One full Perun 3 Mini plus five case charges is six charges, over twice the 2.8 this profile uses in 30 days.
The case claim holds up on Olight's numbers. The Premium manual prints the case cell as "5000 mAh 3.6V (18 Wh)" and the light's cell as 2.34 Wh. Five charges deliver 5 × 2.34 = 11.7 Wh, or 11.7 ÷ 18 = 65% of the cell's energy. The manual's rated capacity of 2,650 mAh at 5 V is 13.25 Wh, and 13.25 ÷ 2.34 = 5.7, so "up to 5 times" is conservative.
Does TSA Allow Flashlights?
Yes. TSA's flashlights page, last updated July 14, 2026, lists flashlights as allowed in both carry-on and checked bags and adds, "The final decision rests with the TSA officer on whether an item is allowed through the checkpoint." The battery inside decides the details, and FAA rules cover those.
The FAA's page on airline passengers and batteries, last updated August 10, 2026, says: "Rechargeable lithium battery-powered devices can be checked only if they are completely powered off and protected from accidental activation while still meeting the Wh restrictions above." Its PackSafe lithium battery page, last updated August 11, 2026, says spare batteries, "including power banks and cell phone battery charging cases, must be carried in carry-on baggage only," citing 49 CFR 175.10(a)(18). TSA's power bank page, last updated May 14, 2025, says the same.
This table applies those rules to each item in the travel kit, with the lithium energy Olight lists and the packing step.
| Kit item | Lithium inside (Olight rating) | FAA category | Where to pack it | Packing step |
|---|---|---|---|---|
| i1R 2 Pro | 130 mAh, 3.7 V, about 0.48 Wh | Device, installed battery | Carry-on; checked only if off and protected | Twist the tailcap counterclockwise to off |
| Perun 3 Mini | 2.34 Wh (650 mAh, 3.6 V) | Device, installed battery | Carry-on; checked only if off and protected | Lockout: hold 2 seconds from off |
| Perun 3 Mini charging case | 18 Wh (5,000 mAh, 3.6 V); charges phones | Charging case with its own battery | Carry-on only | Keep it with you if a bag is gate-checked |
| Oclip 2 Pro | 2.22 Wh (600 mAh, 3.7 V) | Device, installed battery | Carry-on | Lockout: hold the side button over 2 seconds from off |
| Oclip 2 Premium charging dock | 3.7 Wh (1,000 mAh) | Separate battery unit | Carry-on only | Pack apart from keys and coins |
| imini 2 | 80 mAh 10180 cell | Device, installed battery | Carry-on | Keep the body on its magnetic cap |
The FAA's own method is to "multiply the volts (V) by the amp hours (Ah)," and the Oclip 2 figures check out: 0.6 × 3.7 = 2.22 Wh for the light and 1.0 × 3.7 = 3.7 Wh for the dock, matching the manual. The two-light kit with the case holds about 0.48 + 2.34 + 18 = 20.8 Wh.
The cabin is also where a problem gets noticed: the FAA says "Flight crews are trained to recognize and respond to lithium battery fires in the cabin." And the Oclip 2 manual says that when the product "is carried or transported, please lock it."
For watt-hour limits in depth, see our guide to flying with a small pocket flashlight and our comparison of flashlight battery types. The FAA notes that many airlines "may have stricter quantity and Wh limits," so check each carrier.
What Is the Best Portable Flashlight?
The best portable flashlight is the one that is on you when the lights go out, so portability means weight, shape and a hands-free way to carry it. Among Olight's current lights, the Oclip 2 Pro is the most flexible single portable light for travel: 75.5 g, a clip for straps up to 14 mm thick, magnets, red light and USB-C charging.
The Olight Oclip 2 Pro clip flashlight ($54.99, regular price, September 2026, Tidal Blue standard version with a USB-C cable; the Premium versions add a 1,000 mAh charging dock) pairs a floodlight up to 530 lumens with a 3,906 candela, 125 m spotlight. Floodlight Turbo runs 530~300~100 lumens for 1 + 58 + 5 minutes, Medium 100 lumens for 3 hours 45 minutes, Low 10 lumens for 25 hours and Moon 1 lumen for 144 hours. Red runs 40 lumens for 4 hours or 4 lumens for 27 hours. The head tilts 115° and the clip turns 360°.
Its limits: it is IP66 and must not be immersed, it weighs 21.5 g more than the Perun 3 Mini, and alone it needs a charge about every 5.7 days on the profile above. Below 0°C (32°F), its manual limits white light to Low and Medium. If you have an ICD or pacemaker, the manual says to "avoid close or prolonged contact with this product to prevent possible interference," so clip it to a pack strap, not a shirt pocket or chest strap.
The Olight imini 2 mini flashlight ($19.99, regular price, September 2026, Dream Blue) is the lightest: 19.5 g, 55 mm, 50 lumens for 60 minutes. It turns on when pulled off its magnetic cap, which holds a built-in USB plug. At 115 candela and 21 m, it is a daypack light, too dim for a dark road.
Warning: The Oclip 2 manual says, "Do not place, charge, or use this light in a car or other environment where the temperature may exceed 60°C," and "Do not put a hot light into any type of fabric bag or fusible plastic container." Keep lights off rental car dashboards.
Note: The Perun 3 Mini manual warns that if the small battery is swallowed, "it can cause severe internal burns in just 2 hours and may lead to death," and says to "Keep new and used batteries away from children." Children should use these lights only with adult supervision.
Your Travel Flashlight Packing Checklist
Use this checklist a week before a long trip; each step uses a spec or rule from this guide. For most long trips, the travel flashlight kit is the i1R 2 Pro on your keys and the Perun 3 Mini in your daypack.
- Charge every light to full the night before you leave.
- Pack a spare MCC 1A cable, or the charging case if outlets will be rare.
- Check that your wall charger's input reads 100 to 240 V and that it has a USB-A port.
- Pack a plug adapter for each country on the route.
- Lock the Perun 3 Mini and Oclip 2 Pro, and twist the i1R 2 Pro off, before they go in a bag.
- Keep lights and any charging case in your carry-on, and with you if a bag is gate-checked.
- Learn the red and Moon controls at home, not in a dark dorm.
- Top up every night you have an outlet, even for 20 minutes.
