The best travel gadgets
The test for a travel gadget is not whether it is clever. It is whether you take it out of the bag more than once a trip.

The one travel gadget almost everyone should own is a 10,000 mAh power bank - the Anker PowerCore Slim 10000 - because the phone is doing boarding passes, maps, tickets and a hotspot all day and it is the device that runs out. Everything else on this list is conditional on the kind of trip you take.
Travel gadgets have a specific failure mode: they are bought for a trip, used once, and carried on the next six. So the ranking below is not by cleverness - it is by uses per trip, which is the only honest measure of whether an object earned the volume it took. Anything that comes out of the bag once a trip or less is at the bottom of this list on purpose, and three things that are commonly sold as travel gadgets are named at the end as deliberately left off.
The criteria, in order
1) Uses per trip - does it come out daily, or once? 2) Weight and volume against that - a 4-ounce object used daily beats a 2-ounce object used once. 3) Does it replace something else, or add to the pile? 4) Does it have a flight rule attached, as power banks and batteries do?

The one that keeps the device you cannot travel without alive
Anker PowerCore Slim 10000 Power Bank
Your phone is now the boarding pass, the map, the ticket, the translator and the hotspot, and a travel day drains it by early afternoon. Ten thousand milliamp-hours is about three full phone charges, which covers a long-haul day plus the arrival evening before you find a socket. It is flat rather than cylindrical, so it sits in a jacket pocket without being a brick, and at roughly 37 Wh it is far below the 100 Wh threshold airlines cap spare batteries at.
The specs that decide it
- Uses per trip: Daily - the highest on this list
- Capacity: 10,000 mAh, about 37 Wh
- Output: Phone-class, roughly 18-22.5 W
- Flight rule: Carry-on only, like every power bank. No approval needed under 100 Wh
Flaws but not dealbreakers
It will not charge a laptop in any useful sense - at this output it slows the drain rather than reversing it. It also has to be remembered into your personal item, because power banks are banned from checked baggage worldwide.

The cheapest thing on this list that changes a flight
Travel Eye Mask and Earplugs Set
People spend sixty dollars on a travel pillow and nothing on light and noise, which is the wrong order. A cabin light coming on at 2am ends sleep instantly, and engine drone is what stops it starting. A contoured mask - one with eye cups rather than a flat band - blocks the light without pressing on your eyelids, and foam plugs take the drone down a step. Together they cost less than a lounge sandwich and weigh almost nothing.
The specs that decide it
- Uses per trip: Every night flight, and most hotel nights
- Mask: Contoured, so it does not press on the eyes
- Earplugs: Foam - cheap, replaceable, effective on low-frequency drone
- Weight: Negligible
Flaws but not dealbreakers
Foam earplugs are consumable and get grubby fast, so plan on replacing them rather than keeping one pair for a year. A mask also does nothing about a seatmate's screen in your peripheral vision if you sleep on your side with it pushed up.

The one that turns a foreign socket into four of yours
Epicka Universal Travel Adapter
The useful part is not the pins, it is the USB ports. Hotel rooms abroad routinely offer one reachable socket, often behind the bed, and a universal adapter with multiple USB outputs turns that single socket into the phone, the watch, the power bank and the headphones all charging overnight. The retractable pin design also means one object covers Europe, the UK and Asia instead of three.
The specs that decide it
- Uses per trip: Daily, on any international trip
- Covers: Common worldwide pin formats via retractable pins
- USB: Multiple ports - this is the real feature
- Voltage: Adapts shape only. It is not a converter
Flaws but not dealbreakers
It is chunky, and in a worn or slack foreign socket a heavy adapter can hang and work itself loose overnight - which is how you wake up to an uncharged phone. It also does nothing about voltage, so a US-only 120 V appliance still needs a converter.

The one that tells you where the bag is
Apple AirTag
A tracker does not stop a bag going missing - it changes the conversation at the desk from "we are looking into it" to "it is at the connecting airport." That is what shortens a delayed-baggage case. The AirTag wins on network density rather than hardware: it reports through any passing iPhone, and in an airport there are thousands. Put one inside the bag, not on the outside where it can be removed.
The specs that decide it
- Uses per trip: Once per checked bag - but the one time matters
- Network: Apple Find My - the densest consumer network
- Requires: An iPhone. There is no Android app
- Battery: User-replaceable coin cell, about a year
Flaws but not dealbreakers
It is useless without an iPhone, and Apple publishes no Android app at all. It also has no speaker loud enough to find a bag in a noisy hall, and a bare AirTag has no attachment point - you need a holder or a pocket for it.

The one that pays for itself the first time
Etekcity Digital Luggage Scale
This costs less than a single overweight bag fee, and it pays for itself the first time it stops one. The lb/kg switch is the part that matters abroad, where the limit is quoted at 23 kg rather than 50 lb, and where cabin bags are routinely weighed at 7 to 10 kg - a limit most US flyers have never had applied to them. Weigh at home for the outbound and in the hotel room for the trip back, which is the leg that actually goes wrong.
The specs that decide it
- Uses per trip: Twice - before each flight
- Capacity: Reads to about 110 lb / 50 kg
- Units: Switches lb and kg - the feature that matters abroad
- Weight: A few ounces, so it travels for the return leg
Flaws but not dealbreakers
You have to lift the bag clear of the floor to read it, which is awkward at 50 lb and genuinely difficult if lifting is a problem for you. Cheap strain gauges also drift over time, so sanity-check it against a known weight once a year.

The one that stops the cable hunt
Bellroy Tech Kit Compact
This is the gadget that makes the other gadgets usable. Loose cables in a bag migrate, tangle and end up at the bottom under the shoes, and the compact size here is deliberate - it holds the kit a normal traveler carries rather than inviting you to pack a studio. Fitted pockets mean you can tell what is missing by looking, which is how you avoid leaving a charger in a hotel.
The specs that decide it
- Uses per trip: Daily - it is where the charger lives
- Holds: Cables, a wall charger, earbuds, a small power bank
- Structure: Fitted pockets rather than one open space
- Format: Compact - sized for a real kit, not a studio
Flaws but not dealbreakers
It is expensive for a pouch, and the fitted pockets that make it tidy also make it inflexible - an oddly shaped charger or a chunky adapter may not go in. A freezer bag does eighty percent of this for nothing.

The one that solves a problem security creates
Collapsible Travel Water Bottle
You cannot take water through security and you can take an empty bottle, which makes this a problem of volume rather than rules. A collapsible bottle rolls to a disc in a bag pocket, then fills at a fountain past the checkpoint - and on a long flight it means you are not waiting for a cabin service to get a drink. Cabin air is dry enough that this matters more than it sounds.
The specs that decide it
- Uses per trip: Daily
- Empty size: Rolls to a disc
- Security: Must be empty at the checkpoint. Fill it after
- Replaces: Buying bottled water airside at airport prices
Flaws but not dealbreakers
Collapsible bottles are flexible, which means they are awkward to drink from one-handed and prone to leaking at the cap seam once the silicone has been folded a few hundred times. They also do not keep anything cold.

The one that only earns its place past a week
Travel Clothesline with Suction Cups
This is last on the list because on a four-day trip it never leaves the bag. On a two-week carry-on trip it is the thing that makes the whole plan work: a sink wash is useless without somewhere to dry it, and a hotel towel rail dries nothing overnight. The braided design grips fabric without pegs, which is the detail that separates this from a length of string.
The specs that decide it
- Uses per trip: Once or twice - and only on trips over about a week
- Pegs: None needed - the braid grips the fabric
- Mounts: Suction cups, plus hooks for a rail or a shower bar
- Weight: Almost nothing
Flaws but not dealbreakers
Suction cups fail on textured tile and on the half-tiled walls common in older hotels, so plan on the hooks. It is also genuinely dead weight on any trip short enough not to need laundry, which is most of them.

Ranked by uses per trip
| Gadget | Uses per trip | Weight | Flight rule | Main flaw |
|---|---|---|---|---|
| Power bank, 10,000 mAh | Daily | About 7 oz | Carry-on only | Will not charge a laptop |
| Eye mask and earplugs | Daily | Negligible | None | Earplugs are consumable |
| Universal adapter | Daily, abroad | About 7 oz | None | Can hang loose in a worn socket |
| Bluetooth tracker | Once per checked bag | Negligible | None | iPhone only |
| Luggage scale | Twice | A few oz | None | You must lift the bag |
| Tech pouch | Daily | Light | None | Expensive for a pouch |
| Collapsible bottle | Daily | Light | Empty at security | Leaks at the seam eventually |
| Travel clothesline | Once, past a week | Negligible | None | Dead weight on short trips |
How these were chosen
Four criteria, applied in order. The first one does most of the work.
- Uses per trip. The only honest measure of whether something earned its volume. A gadget used once a trip has to be solving a genuinely expensive problem to justify itself - the luggage scale does, the clothesline only does on a long trip.
- Weight and volume against that figure. Seven ounces of power bank used daily is a better trade than two ounces of something used once.
- Does it replace something, or add to the pile? The universal adapter replaces three country-specific adapters. The tech pouch replaces nothing but makes everything else findable, which is why it is in the middle rather than the bottom.
- Does it have a flight rule attached? Anything with a lithium cell does. Power banks are carry-on only, worldwide, with no exceptions - that constraint is part of the product.
We have not lab-tested any of these and we do not claim to have. The picks come from the specs that decide the purchase and from the published behavior of each category — the full standard is on our methodology page.
The rules that apply to half this list
Anything with a lithium cell - the power bank, the tracker, the earbuds in your tech pouch - is subject to the same baggage rule, and it is the one travel gadget rule worth memorising: spare lithium batteries travel in the cabin, never in the hold.
- Under 100 watt-hours: allowed in carry-on with no approval. A 10,000 mAh bank is about 37 Wh.
- 100 to 160 Wh: allowed in carry-on with airline approval.
- Over 160 Wh: prohibited.
- Convert with Wh = mAh / 1000 x 3.7, so 25,000 mAh is about 92.5 Wh and 30,000 mAh is about 111 Wh - over the free limit.
A growing number of carriers now also prohibit *using* a power bank in flight while still allowing you to carry it. Both rules are set out in power bank rules for flights, and if the device you need to keep alive is a laptop rather than a phone, the output figures are different enough to need their own page — best power banks for laptops.
Which of these to actually pack
| Trip | Take | Leave |
|---|---|---|
| Domestic weekend | Power bank, tech pouch | Adapter, scale, clothesline |
| Long-haul overnight | Power bank, eye mask and plugs, bottle | Clothesline |
| Two weeks abroad | All eight | — |
| Work trip with a laptop | Tech pouch, adapter, power bank | Clothesline, scale |
| Any trip with a checked bag | Add the tracker and the scale | — |
Three things deliberately left off
- Travel-size steamers and irons. They are heavy, they need mains power, and a hot shower in a closed bathroom releases most fold lines for free. The packing method matters far more — how to pack a suitcase without wrinkles.
- Portable luggage locks sold as anti-theft devices. A zipped case can be opened with a ballpoint pen through the teeth and closed again behind you. A lock buys you a tamper-evident seal and an inspection that ends relocked rather than cut off, which is worth having and is not security — how to set a luggage lock.
- Neck wallets and hidden money belts. They solve a problem that card-based travel mostly removed, and the thing you actually need quick access to - a phone and one card - is the thing a money belt makes slowest to reach.
If you want the full kit for a specific trip type rather than a gadget list, start with travel essentials for women, travel essentials for men or long-haul flight essentials.
The tracker slot worth having
A Bluetooth tracker will not recover a stolen passport - but the realistic failure is that you set the wallet down at a hotel desk, and in a populated place a tracker reports its position through other devices nearby. That is why a passport holder with an AirTag pocket is worth a dollar or two more, and no more than that: the best passport holders has the honest version.
