Anker Prime Power Bank (20K, 220W)
140W from one port; the pick if a dead laptop would ruin the trip.

Best everyday portable charger
UGREEN MagFlow Magnetic Power Bank 10000mAh 25W
Snaps on magnetically, 25W rated, 36Wh clears the cabin limit.

Best GaN wall charger
UGREEN Nexode Pro 65W 3-Port GaN Charger
65W with folding prongs; runs a MacBook Air, not a 16-inch Pro.

Best USB-C cable
Anker Zolo USB-C to USB-C Cable (240W, braided)
240W rated with a 5A e-marker; USB 2.0 data is the honest trade.

Best sleep mask with built-in speakers
MUSICOZY Sleep Mask Headphones (100% Blackout 3D)
100 percent blackout with flat speakers; for rain sounds, not music.

Our top pick
Anker Prime Power Bank (20K, 220W)
How the Prime 20K scores
Anker Prime Power Bank (20K, 220W). The ten picks on this page are slotted by job, not ranked as a league table, and this one earns the top slot because a dead laptop or phone on a long flight is the failure that ruins the trip.
It pushes 140W down a single USB-C port, refills itself at 100W, and shows what each port is doing. At 18.0 oz (510 g) it is the heaviest thing on this page, and that is the honest cost of that power.
It scores 8.2 while the Sony WH-1000XM6 below scores 9.0, and we will not hide that: the Sony is the best noise cancelling here. The Prime holds the trophy because power is the one job every other pick on the page quietly depends on.
Good
- 140W from one USB-C port, fills a large laptop fast
- 220W total across three ports at once
- 100W recharge input
- Display shows the figure for each port
Watch
- 18.0 oz (510 g), the heaviest pick on this page
- 39.4 mAh per gram is under the 40 mAh/g line, the honest cost of 140W

The best travel gadgets, side by side
The same ten picks as a reference table, the format answer engines quote most. Scroll sideways on a phone; where a maker publishes no weight or size, the cell reads Not stated rather than a guess.
| Pick | The job it does | Expert score | What it weighs or how big it is | The one number that matters | Carry-on note |
|---|---|---|---|---|---|
| Anker Prime Power Bank (20K, 220W) | Best power bank for a long flight | 8.2 | 18.0 oz (510 g) | 140W from one USB-C port | 72.36Wh, under the 100Wh cabin limit |

How we tested these. Our verdicts combine hands-on testing by the SGK team with trusted independent lab data.
SGK owns none of the ten products on this page. Every hard performance figure in the picks below is attributed inline to its named source: Portable Power Backup, SoundGuys, ZDNET, CNN Underscored, RTINGS, What Hi-Fi and Tech Inspection.
Where only the maker’s rating exists, the pick says whose rating it is: Sony’s 30 hours, GL.iNet’s VPN throughput, MUSICOZY’s 16 hours. Alisdair, a network engineer with 9 years behind him, leads the work, with Darleene co-signing.
Darleene asks“I’m on a red-eye next month. Do I take the sleep mask or the earbuds? I genuinely can’t decide.”
Alisdair’s answer: it depends which one is keeping you awake. If it is the noise, take the earbuds; SoundGuys measured 9 hours 32 minutes of ANC on the WF-1000XM5, which covers any overnight flight.
If it is the light, take the mask. The MUSICOZY blocks 100 percent of it, and the flat speakers still work when you are on your side, which is where most masks fail.
If it is both, pack the earbuds and an eye mask you already own; that is the lighter bag. Just remember the mask is for rain sounds and audiobooks, not music.
Pick 01Best power bank for a long flight
Best power bank for a long flight: Anker Prime Power Bank (20K, 220W)
The one thing to pack if you pack nothing else.

Model A110B, 20,100mAh, 72.36Wh. Three ports share a 220W ceiling: 140W max from a single USB-C, 22.5W from the USB-A, and a 100W recharge input.
Portable Power Backup pushed 140W to a 16-inch MacBook Pro (M4 Pro) on a 5A cable and reached 50 percent in 28 minutes. That is the difference between a laptop that survives a long flight and one that does not.
It is 18.0 oz (510 g) and 1.7 x 2.0 x 5.8 in (44 x 50 x 147 mm), with a per-port display showing what each port is doing. Power-to-weight works out to 39.4 mAh per gram, under the 40 mAh/g line, and it is the heaviest thing on this page; that is the honest cost of 140W.
The 72.36Wh sits comfortably under the 100Wh airline cabin limit. That watt-hour figure comes from the independent review, not from Anker’s own page, and it is the number a gate agent can actually check.
Airline: 72.36Wh, inside the usual 100Wh carry-on limit. Always check your airline.
Good
- 140W from one USB-C port, fills a large laptop fast
- 220W total across three ports at once
- 100W recharge input
- Per-port display shows which cable is the fast one
Watch
- 18.0 oz (510 g), the heaviest pick on this page
- 39.4 mAh/g under the 40 line; that bulk is the honest cost of 140W
Pick 02Best everyday portable charger

What plain Qi2 tops out at; the 25W rating sits above it
Source: the Qi2 specification
Model PB773, 10,000mAh, 36Wh. The pack is two cells in series at 7.2V, which is why the figure is 36Wh and never 37Wh; the 10,000mAh at 3.7V arithmetic that circulates on third-party spec tables does not apply to this unit.
It snaps to the back of a Qi2 phone and charges at up to 25W, with one USB-C port alongside the magnetic pad. Qi2 itself tops out at 15W, this unit is rated 25W by UGREEN, and reaching that rating needs a 30W or higher adapter; a phone’s own charging figure is never rounded up to the charger’s rating.
No independent measured figure exists for this unit, so every number here is UGREEN’s own rating and we make no measured claim. This is the everyday portable charger: small enough to forget in a pocket, strong enough to refill a phone comfortably, and clear of the cabin limit at 36Wh.
Airline: 36Wh, far inside the usual 100Wh carry-on limit. Always check your airline.
Good
- Snaps on magnetically, no cable to the phone
- USB-C port charges a second device
- 36Wh clears the 100Wh cabin limit easily
Watch
- 25W needs a 30W or higher adapter you pack yourself
- No independent measured figure exists; all figures are UGREEN’s own

Air, not Pro
Runs a MacBook Air at full speed; a 16-inch Pro charges slowly
Source: our call, from the 65W ceiling
Model CD381, 65W total, and 65W from a single USB-C port. Two USB-C ports, one USB-A, GaN inside, 100 to 240V input and folding prongs.
This is the wall charger that runs a MacBook Air at full speed. It will charge a 16-inch Pro slowly, and under a heavy load it may hold steady rather than build, so the job it does is everything up to a thin laptop.
The plug shape is fixed. There are no interchangeable plug heads, whatever an older listing claimed, so pair it with the universal adapter below when the wall socket is not a US one.
It sits at the premium end of the GaN class, and the travel versatility bar of 9.5 reflects the brief here: one small block, folding prongs, three ports, most of the world’s voltage.
Good
- 65W from a single USB-C port
- Folding prongs that will not scratch a laptop
- 100 to 240V input covers most of the world
Watch
- A 16-inch Pro charges slowly, not under load
- One fixed plug shape, no interchangeable heads
Pick 04Best USB-C cable
Best USB-C cable: Anker Zolo USB-C to USB-C Cable (240W, braided)
Full laptop power, in nylon that survives a bag.

Source: Anker’s own listing
Model A8060, rated 240W with a 5A e-marker, in double-braided nylon. It carries full laptop power all day and shrugs off a bag pocket.
The weakness is data, and it is a real one: USB 2.0 at 480Mbps. Moving photos or video off a phone over this cable crawls, so treat it as a power cable that happens to pass files, not the other way round.
SGK does not own this cable and has not tested it; a live page once claimed otherwise and was corrected. Every figure here is Anker’s own rating.
On value it sits at the premium end of the USB-C cable class. What the money buys is the double braid and the 5A e-marker, and against the Belkin BoostCharge 240W it is the better braid.
Good
- 240W rated with a 5A e-marker
- Double-braided nylon build
- Charges a laptop at full speed
Watch
- USB 2.0 data at 480Mbps is slow for files
- Premium end of the cable class
Pick 05Best compact noise cancelling

The WF-1000XM5 is 0.21 oz (5.9 g) per bud and 1.4 oz (39 g) with the case. IPX4, Bluetooth 5.3 with two-device multipoint, and the case charges wirelessly.
SoundGuys measured 9 hours 32 minutes of ANC-on playback on a single charge, past Sony’s own 8-hour claim. Codecs run SBC, AAC, LDAC and LC3.
On the six-criterion headphone rubric, the two bars not shown here are Sound Quality at 8.5 and Calls, App and Connectivity at 7.5, where the mic falls well short of the over-ear model in noise.
The honest cons: it is not as good overall as the WH-1000XM6 on this same page, IPX4 is splash resistance only, and the mic is weak in a noisy cabin.
One more thing, said plainly: SGK owns the WH-1000XM5 over-ear, which is a different product and not on this page. There is no first-person claim here; the figures are Sony’s own specs and SoundGuys’ measurement.
Good
- 9h 32min of ANC measured by SoundGuys
- 1.4 oz case with wireless charging
- LDAC and LC3 among the codecs
Watch
- Not as good overall as the WH-1000XM6 on this page
- IPX4 only, splash resistance
- Mic weak in noise
Pick 06Best universal travel adapter

Model TS-WTA05. Type C, G, A and I plugs slide out of one block, covering the EU, UK, AU and US and more than 200 countries, with GaN and 65W USB-C PD.
The AC side is rated 100 to 250V, 10A, 2500W max, and the fuse is a replaceable 250V 10A with a spare in the box.
ZDNET, Adrian Kingsley-Hughes, tested it on both 240V and 110V input and measured the full 65W from a single USB-C port, and 45W from a USB-C port with four ports in use.
Now the one thing buyers get wrong about this category. It passes voltage through; it does not convert it. A 110V-only hair dryer on a 230V wall will die, and a 230V kettle on 110V will barely warm, so leave heat appliances at home.
The certification story is thinner than the big-brand wall chargers, which is why Safety Certifications sits at 7.5 while country coverage runs 9.0.
Good
- Four plug types in one block, 200-plus countries
- ZDNET measured the full 65W from one port
- Replaceable fuse with a spare in the box
Watch
- Passes voltage through, does not convert it; no hair dryers, no travel kettles
- Certification story thinner than the big brands, hence the 7.5 bar

The AirTag works with iPhone and iPad only. There is no Android version at all, and that single fact is why Platform Fit scores 6.5 while every other bar on this pick sits at 8.5 or higher.
Model A2937, the second generation, single pack. This is not the four-pack and not the discontinued first generation.
The second-generation Ultra Wideband chip gives Precision Finding at up to 1.5 times the first generation’s range, now from an Apple Watch as well as an iPhone, and the speaker is about 50 percent louder. The battery is a user-replaceable CR2032 good for about a year, and the tag is IP67, which is splash and rain rather than swimming.
At 0.42 oz (11.8 g) with NFC for Lost Mode, it disappears on a strap, in a wallet or inside a bag.
Good
- Precision Finding at up to 1.5x the first generation
- Speaker about 50 percent louder
- User-replaceable battery, about a year
Watch
- iPhone and iPad only; no Android at all
- IP67 is splash and rain, not swimming

Source: GL.iNet’s own figures, no independent VPN measurement exists
The Beryl AX is a Wi-Fi 6 travel router, AX3000 class: 2402Mbps on 5GHz and 574Mbps on 2.4GHz, on a MediaTek MT7981B dual-core 1.3GHz with 512MB of DDR4.
The job: it gets online from hotel Wi-Fi, a tethered phone or a USB cellular dongle, and shares that connection with everything you carry. It has no built-in eSIM and no cellular modem of its own, which belongs in the cons as much as here.
Ports are 1x 2.5G WAN, 1x 1G LAN and 1x USB 3.0 Type-A. RTINGS found the Beryl AX delivers good performance for its size, with decent range, and is unusually actively cooled for a travel router.
It is 6.9 oz (196 g), 4.2 x 3.3 x 1.3 in (106 x 83 x 33 mm), and runs from USB-C at 5V/3A, under 8W, so a power bank keeps it alive through a long day.
VPN is the other reason to pack it. WireGuard runs up to 300Mbps and OpenVPN up to 150Mbps on OpenWrt, and both figures are GL.iNet’s own; no independent VPN throughput measurement exists.
Good
- WireGuard VPN on OpenWrt, per GL.iNet up to 300Mbps
- Runs off a power bank at under 8W
- 2.5G WAN plus LAN and USB 3.0 in a 6.9 oz box
Watch
- No built-in eSIM and no cellular modem; needs a source of internet
- VPN figures are GL.iNet’s own, not independently measured

The WH-1000XM6 is the best noise cancelling on this page, full stop. What Hi-Fi rates it the class leader for noise cancelling and for sound, calling them better than the rival Bose.
The QN3 HD Noise Cancelling Processor reads 12 microphones, and the battery is rated at 30 hours with ANC on, which is Sony’s own figure. Codecs run SBC, AAC, LDAC and LC3 with two-device multipoint.
On the six-criterion headphone rubric, the two bars not shown are Comfort and Fit for Long Wear at 8.5, where the ears warm on long sessions, and Calls, App and Connectivity at 8.5.
It no longer folds, so the case is bulky. On a plane it is big and chunky, and it takes bag room the earbuds above do not; a winner if you can live with the bulk, and the wrong shape if you pack light.
It scores 9.0 against the winner’s 8.2, and that is correct, because this page slots by job. The top slot went to the Anker Prime because a dead laptop or phone on a long flight is the failure that ruins the trip.
Good
- What Hi-Fi calls it the class leader for ANC and sound
- 30 hours ANC-on, Sony’s own rating
- Two-device multipoint, LDAC and LC3

The MUSICOZY GH01 is a sleep eye mask with ultra-thin flat Bluetooth 5.4 speakers in the headband. It is 3D contoured for 100 percent blackout with no pressure on the eyes, works for side sleepers, adjusts with hook-and-loop, and the cotton blend and silk cover is hand or machine washable.
It is for falling asleep to rain sounds or an audiobook, not for listening to music; the Audio Quality bar sits at 6.5 for a reason.
Every spec figure on this pick is MUSICOZY’s own. The rated playtime is 16 hours, the maker’s figure, while independent use reports from Tech Inspection put it nearer two or three nights per charge at moderate volume; both are printed above and labelled.
SGK owns none of the ten products on this page, and this one is no exception. The only independent reading we have is the battery one, and we claim nothing more.
Good
- 100 percent blackout with no eye pressure
- Flat speakers that still work for side sleepers
- Hand or machine washable
Watch
- Audio is a 6.5; this is for rain sounds and audiobooks, not music
- Battery bar 6.0: 16 hours is the maker’s own rating, independent use says two to three nights
The bottom line
Buy the Anker Prime 20K 220W if you pack one thing. It is the pick whose failure would actually ruin the trip, and at 72.36Wh it clears the cabin limit with room to spare.
Buy the UGREEN MagFlow for everyday phone top-ups, the Nexode Pro 65W as the wall charger, and the Zolo 240W cable to join them.
Fly often: the Sony WH-1000XM6 for silence, the WF-1000XM5 when the bag is small, the TESSAN for the wall socket, and the AirTag so the bag itself is findable.
The Beryl AX turns bad hotel Wi-Fi into a network you control, and the MUSICOZY mask is the pick for anyone who cannot sleep in a lit cabin.
Ten picks, slotted by job rather than ranked as a league, every figure attributed to its source above.
Airline and plug rules, in plain English
Airlines limit lithium by energy, not capacity. The common cabin limit is 100Wh per battery without asking, and both power banks on this page clear it: the Anker Prime at 72.36Wh and the MagFlow at 36Wh.
Loose lithium travels in the cabin, never in the hold. A power bank in checked luggage can be removed from your bag or the bag refused, so both banks belong in the bag under the seat in front.
A plug adapter is not a voltage converter. The TESSAN passes the wall voltage straight through, which is why phones, laptops and GaN chargers are fine behind it and heat appliances are not; a hair dryer or travel kettle needs a true converter or a dual-voltage design.
The full rules, with the limits for larger batteries, live in our guide to taking a power bank on a plane.
