Best Travel Accessories for Carry-On Travelers (2026)
Must-have travel accessories for carry-on-only trips: luggage scales, packing cubes, TSA locks, toiletry bags, and more. 10 picks for 2026.
Carry-on-only travel is a skill, and the right accessories are what make it work. A digital luggage scale prevents a £50 gate-check fee. Packing cubes compress a week's clothes into a 40 L bag. A clear toiletry bag avoids delays at security.
This guide covers the 10 accessories that frequent carry-on travelers consider non-negotiable — with picks at realistic price points.
Why accessories matter for carry-on travel
The constraint of carry-on-only travel is not just the bag — it's the bag plus everything in it fitting within both the size gauge and weight limit. Accessories that compress, organise, and weigh your pack are multipliers: they let you carry more within the same limits.
Airlines like Ryanair (10 kg) and Wizz Air (10 kg) enforce weight limits at the gate. Getting caught 500 g over costs more than buying the scale that would have prevented it.
Our top picks
1. Etekcity Luggage Scale — Best luggage scale
Price: ~$10 | Capacity: 50 kg | Accuracy: ±100 g
A digital luggage scale is the single most cost-effective travel purchase you can make. The Etekcity reads to 50 kg with ±100 g accuracy — close enough to trust when your airline's limit is 10 kg. Hook it to your bag's handle, lift the scale, and read the display.
Pros:
- Costs less than a single airline overweight fee
- Accurate enough for travel use
- Compact and lightweight — fits in any bag
Cons:
- Requires two hands (one to hold the scale, one to lift the bag)
- Battery-powered — bring a spare on extended trips

2. Eagle Creek Pack-It Cubes — Best packing cubes
Price: ~$30–40 (set of 3) | Sizes: S, M, L
Packing cubes separate your bag into zones and compress clothes. Eagle Creek's Pack-It Cubes are the most durable on the market — a mesh top lets you see contents without unpacking. The system is addictive once you try it: shirts in one cube, bottoms in another, and everything accessible without disturbing the rest.
Pros:
- Durable mesh-and-nylon construction holds up to travel
- Visible mesh top — find items without opening
- Set of three covers most packing needs
Cons:
- More expensive than generic alternatives
- Cubes add slight weight themselves (negligible but real)
Note: Placeholder ASIN — verify the listing before purchasing.
3. Gonex Compression Packing Cubes — Best compression bags
Price: ~$25 (set of 4) | Compression: ~60% volume reduction claimed
Compression packing cubes add a two-way zip that forces air out as you close them. The volume reduction isn't 60% in practice (more like 30–40%), but that's enough to fit an extra layer into a tight bag. Useful for bulky items: fleeces, hoodies, towels.
Pros:
- Meaningful volume reduction for bulky clothing
- Combined packing cube + compression = double function
- Inexpensive
Cons:
- Compression doesn't reduce weight — only volume
- Fully compressed cubes can be rigid and harder to fit in odd spaces
- Some items (delicate fabrics) may wrinkle more when compressed
Note: Placeholder ASIN — verify the listing before purchasing.
4. TSA-Approved Combination Lock — Best TSA lock
Price: ~$10–15 | Type: 3-dial combination
A TSA-approved lock uses a secondary keyway that TSA agents can open with a master key — meaning they can check your bag without cutting the lock. Look for the Travel Sentry or Safe Skies logo. The Forge TSA Lock is a reliable, compact option.
Pros:
- TSA can open without damaging your lock
- 3-dial combination — no key to lose
- Small profile fits most zip pulls
Cons:
- Won't stop a determined thief — deters opportunistic theft only
- Combination can be forgotten on long trips
Note: Placeholder ASIN — verify the listing before purchasing.
5. Gonex Toiletry Bag — Best toiletry organiser
Price: ~$20 | Style: Hanging toiletry bag with hook
A hanging toiletry bag unfolds and hooks onto a towel rail or door hook — giving you a mini vanity in any bathroom without unpacking onto a potentially wet surface. The Gonex option has enough pockets for a full grooming kit without being too bulky.
Pros:
- Hanging hook works in any bathroom
- Waterproof lining — safe around shampoo and shaving gel
- Multiple pockets keep items organised
Cons:
- More volume than a simple zip pouch — takes up meaningful bag space
- Hook can snag on other items in the bag
Note: Placeholder ASIN — verify the listing before purchasing.
6. Anker PowerCore 10000 — Best portable charger
Price: ~$25 | Capacity: 10,000 mAh | Output: USB-A + USB-C
A 10,000 mAh power bank gives a full charge to most phones about 2.5 times. It's the most useful size: larger banks (20,000+ mAh) are increasingly restricted by airlines (most allow up to 27,000 mAh / 100 Wh, but gate agents sometimes question large banks). The Anker PowerCore 10,000 fits in a jacket pocket.
Pros:
- Compact — fits in a jacket pocket or personal item
- USB-A + USB-C covers almost all modern devices
- Well within airline power bank limits
Cons:
- Must go in cabin bag (hand luggage), never checked baggage
- Slower charging than newer GaN chargers
- USB-A port may eventually feel dated
Note: Placeholder ASIN — verify the listing before purchasing.
7. Trtl Pillow — Best travel pillow
Price: ~$40 | Style: Neck support wrap
The Trtl is not a U-shaped pillow. It's a soft-wrap with an internal rigid support that holds your head upright from the side. It compresses to almost nothing compared to inflatable U-pillows and provides better side-sleeping support. For long-haul economy, it's the most effective compact option.
Pros:
- Compresses to 1/4 the size of a U-pillow
- Holds head upright from the side — better for side-sleepers
- Machine washable
Cons:
- Works best for side-sleeping; front-sleepers may find a J-pillow better
- Some people find the rigid support uncomfortable
Note: Placeholder ASIN — verify the listing before purchasing.
8. Osprey Ultralight Dry Sack — Best waterproof protection
Price: ~$15 | Sizes: 1.5 L, 6 L, 12 L, 20 L
A dry sack keeps electronics and documents protected from spills inside your bag. The 6 L size fits a 13" laptop, cables, and a passport. Useful even without rain — spilled water bottle in the overhead bin has ruined many laptops.
Pros:
- Roll-top closure creates a genuine watertight seal
- Doubles as a compression bag for soft items
- Lightweight and takes up minimal space when empty
Cons:
- Roll-top is less convenient than a zip for frequent access
- Oversized for daily electronics — size selection matters
Note: Placeholder ASIN — verify the listing before purchasing.
9. Lewis N. Clark Neck Wallet — Best security wallet
Price: ~$15 | Style: Under-shirt neck pouch
A neck wallet keeps your passport, credit cards, and cash against your body — invisible under a shirt. Essential in high-pickpocket destinations (Barcelona, Rome, Prague). The Lewis N. Clark version uses RFID-blocking material.
Pros:
- RFID-blocking material protects contactless cards
- Invisible under most shirts
- Inexpensive insurance for travel documents
Cons:
- Uncomfortable in warm weather — wears against the chest
- Can be awkward to access in busy situations
Note: Placeholder ASIN — verify the listing before purchasing.
10. Apple AirTag (4-pack) — Best bag tracker
Price: ~$99 for 4 | Technology: UWB + Bluetooth
An AirTag slipped inside your carry-on doesn't help much in the overhead bin — it shines when your bag gets gate-checked unexpectedly or when the airline misroutes it. The Apple Find My network means any iPhone nearby pings its location back to you. A pack of four covers all your bags.
Pros:
- Near-universal coverage via Apple's Find My network
- CR2032 battery lasts ~1 year
- Compact (slightly larger than a 1p coin)
Cons:
- Requires iPhone for full functionality
- Android users have limited tracking capability
- Samsung SmartTags or Tile may be better for Android-heavy households
Note: Placeholder ASIN — verify the listing before purchasing.
