Quick Answer
The brick in your laptop box is the most replaceable thing you own
Empty your travel bag onto a hotel bed and count the power supplies. The laptop’s boxed charger, fat as a deck of cards with its captive cable. The phone cube. The tablet’s cube, which is somehow a different cube. A fourth for the earbuds, because of course. Four bricks, four cables, four outlets: in a room that has two, one of which is behind the headboard.
Now the loop worth closing: every one of those bricks except the laptop’s is optional, and the laptop’s is the most optional of all. A single modern charger the size of the phone cube can run the whole pile. That’s not marketing; it’s a materials change. And it’s the reason a category of gear that nobody thought about for twenty years suddenly got interesting.
Here’s the honest one-paragraph version of the science, and then we’ll never mention it again. Old chargers switch power using silicon transistors, which leak roughly 10-15% of the energy they handle as waste heat. Gallium nitride (GaN) is a different semiconductor that switches much faster and much cleaner, wasting closer to 5%. Less heat means smaller heat sinks, fewer and smaller internal components, and less air space needed inside the case, so the same wattage collapses into a far smaller box. That’s the whole trick: a 100W GaN charger can genuinely be smaller than a chunky old 5W silicon adapter. It does not charge your phone “better,” it does not extend battery life, and a GaN charger with a low wattage rating is still a low-wattage charger. It just stops the wattage you’re paying for from needing a brick to live in.
The five below span 67W to 100W and four brands, because this is not a one-company category. If you specifically want the Anker-only view (power banks, cables and chargers as one ecosystem) we cover that separately in our guide to the best Anker chargers for travel .
The best size-to-power ratio here: 67W to a single device (real laptop wattage) from a block about 1.5 inches square with prongs that fold flat. Two USB-C plus one USB-A, PPS support, around 4.78 oz. The catch is that output splits under load: 65W across two devices, about 64.5W across three, so a laptop charges slower with company.

UGREEN’s own testing puts a MacBook at 51% in 27 minutes. The catch is bulk: those extra ports make it a shared-room charger more than a solo carry-on item.

GaN6 Pro internals with dual cooling. The catch is that two of the four ports are USB-A, so only the two USB-C ports carry the real fast-charging load.

The catch is sharing: two USB-C devices split roughly 60W/30W, well below what the 4-port picks sustain, so it suits one or two devices, not a whole table.

The catch is that it is non-PPS, so recent Samsung Galaxy and Google Pixel phones cap around 9V and never reach their fastest charging speed: iPhones and laptops are unaffected.

Pick by how many devices you actually plug in at the same time, then by how small you need the block to be. Most solo travelers are over-buying wattage and under-buying portability.
| Charger | Max wattage | Ports | Travel form factor | Best for |
|---|---|---|---|---|
| Anker Prime 67W GaN Our pick | 67W single / 65W dual | 2× USB-C + 1× USB-A | ~1.5in square, foldable prongs, ~4.78 oz | Best overall size-to-power balance |
| UGREEN Nexode 100W 4-Port | 100W single port | 4× USB-C | Wall-plug form factor, larger | A laptop plus multiple devices at once |
| Baseus GaN6 100W 4-Port | 100W single port | 2× USB-C + 2× USB-A | Foldable plug, compact, extension cord included | Best value multi-port |
| Satechi 100W Compact GaN | 100W single port | 2× USB-C + 1× USB-A | Compact charging station | Mac-focused travelers |
| Amazon Basics 100W GaN | 100W single port | 2× USB-C + 2× USB-A | Foldable plug | Best budget 100W pick |
Verdict: Buy the Anker Prime 67W unless you regularly charge two laptops at once: then take the UGREEN Nexode 100W.
Anker Prime 67W GaN: the one that actually disappears
This is the pick for the traveler carrying one laptop, one phone and one accessory, which is most of us. 67W to a single device is enough to fast-charge a MacBook Air, most 13-14 inch Windows ultrabooks and every tablet made, from a body about 1.5 inches square (Anker puts it at 51% smaller than Apple’s original 67W adapter) weighing around 4.78 oz. The prongs fold flat, so it packs like a stone rather than a caltrop, and PPS support means recent Samsung and Pixel phones reach their proper fast-charging speeds. ActiveShield 2.0 temperature monitoring runs in the background.
The catch is the one that applies to every charger on this page, just stated honestly: the wattage is a pool, not a per-port promise. Plug in a second device and the total drops to 65W; a third takes it to about 64.5W. Your laptop doesn’t stop charging, but it visibly slows while the phone drinks. In practice the fix is boring and effective: charge the laptop alone while you shower, then move it to the phone overnight.
- Full 67W laptop-class output from a ~1.5in, ~4.78 oz block
- Foldable prongs pack flat and won't snag a bag lining
- PPS support, so Samsung and Pixel phones charge at full speed
- Three ports (2× USB-C + 1× USB-A) cover a whole solo kit
- ActiveShield 2.0 temperature monitoring
- Total output is shared: 65W across two devices, ~64.5W across three
- 67W is short of what a 16in performance laptop wants under full load
- Only one USB-A port for older accessories
UGREEN Nexode 100W 4-Port: for when it’s not just your gear
Four USB-C ports, no compromise ports, and 100W available to a single port. The trick that earns its place is that the two highest-power ports can run two laptops simultaneously: genuinely rare, and the difference between one charger and two when you and a travel partner both work on the road. UGREEN’s own testing puts a MacBook at 51% in 27 minutes, which matches the felt experience of a laptop that tops up over a coffee rather than over an evening.
The catch is physical. Four ports need a wider body, and this is the least pocketable pick here. Think of it as the charger that lives on the nightstand for the whole room, not the one you clip to a daypack for the day. If you want most of that coverage in something that folds, the Baseus below is the compromise.
Baseus GaN6 100W 4-Port: the value multi-port
100W, four ports, foldable plug and a 3.3 ft extension cord in the box: which sounds like filler until the only reachable outlet in a guesthouse is behind the bed frame at ankle height. GaN6 Pro internals with dual cooling keep it stable at load, and it covers MacBooks, iPads, Galaxy phones, Steam Decks and the rest without ceremony.
The catch is port composition: two of the four ports are USB-A, a connector most 2026-era devices have left behind. Effectively you’re buying a two-port fast charger with two legacy ports attached. That’s fine if you still travel with an older e-reader, a headlamp or a camera battery caddy, and irrelevant if everything you own is USB-C, in which case the Anker’s smaller body is the better trade.
Satechi and Amazon Basics: the Mac pick and the budget pick
The Satechi 100W USB-C PD Compact GaN Charging Station is the one Mac-centric travelers gravitate to, and it earns it: a full 100W to a single USB-C port for a MacBook Pro under real load, a second USB-C, a USB-A, and a 2-year limited warranty. Sharing is where it gives ground: two USB-C devices land around 60W/30W, and one USB-C plus the USB-A gives roughly 100W/12W. It’s a one-or-two-device charger that does those one or two devices very well.
The Amazon Basics 100W Four-Port GaN Wall Charger is the honest budget answer: real 100W GaN output, four ports (2× USB-C at 100W/18W, 2× USB-A at 12W), PD 3.0, a foldable plug, overvoltage and short-circuit protection, and a 1-year warranty. Its catch is a single spec line that matters more than its price: it is non-PPS. Samsung Galaxy and Google Pixel phones cap around 9V on it and never reach Super Fast Charging speeds. iPhones and laptops charge exactly as expected. If your phone is a Galaxy, spend the difference elsewhere in this list.
One newer shape worth knowing: the UGREEN Nexode Retractable 45W builds a retractable USB-C cable (about 0.7 m) into a 3-port GaN charger for around $21, which quietly solves the forgotten-cable problem every traveler eventually has.
How to choose a GaN charger for travel (the four specs that matter)
Foldable prongs. A rigid-prong charger is a hook loose in your bag. It catches lining, gouges laptop lids and refuses to lie flat in a packing cube . Every pick here except the UGREEN folds. Treat it as a hard requirement rather than a bonus.
100-240V input, and the adapter/converter distinction people get wrong. Almost all USB-C GaN chargers from Anker, UGREEN, Baseus and Satechi accept a wide global input, commonly 100-240V, which means they work on Japan’s 100V, North America’s 120V and Europe’s 230V without any electrical help at all. What you still need abroad is a plug adapter: a passive shell that changes the shape of the pins so the charger fits a foreign socket. A voltage converter is a completely different, heavier device that steps the voltage itself up or down, and it exists for single-voltage appliances: hair dryers, curling irons, some kettles. Putting a 100-240V charger through a converter buys you nothing. The one thing to actually do: read the fine print on the charger body, because a few individual models are rated narrower (100-220V, for instance). Then pair it with a proper universal travel adapter and you’re covered nearly everywhere.
Ports versus shared wattage. Rated wattage is a ceiling for the whole charger, not a per-port guarantee. Adding a second device redistributes power (the Anker Prime’s 67W becomes 65W total, then about 64.5W across three), and that’s standard behavior across every brand here, not a defect. Decide by simultaneous devices: one laptop plus a phone wants 65W and up; two laptops want 100W and a charger that explicitly supports dual high-power ports, like the UGREEN.
The cable is half the charger. A plain USB-C cable with no e-marker chip is rated for 60W (3A at 20V). Reaching a true 100W needs an e-marked 5A cable, so a 100W charger paired with a bargain unmarked cable quietly delivers 60W and you’ll blame the charger. Going above 100W means USB-PD 3.1, published in 2021, which raised the ceiling to 240W using 28V/36V/48V Extended Power Range modes, but both charger and cable must support EPR for any of that to happen.
One rule you can stop worrying about: the airline battery limits don’t apply here. TSA and FAA restrictions on 100Wh/160Wh capacity govern lithium batteries, and a GaN wall charger has no battery inside it. Pack it wherever you like. It’s your power bank that has to ride in the carry-on.
Frequently Asked Questions
What is the best GaN wall charger for travel?
The Anker Prime 67W GaN 3-Port charger is the strongest all-round pick for most travelers: it delivers laptop-level 67W in a block about 1.5 inches square with folding prongs. Travelers charging multiple devices or laptops at once should consider the UGREEN Nexode 100W 4-Port, which can power two laptops simultaneously.
Why are GaN chargers smaller than regular chargers with the same wattage?
GaN (gallium nitride) chargers use a semiconductor that switches power far more efficiently than the silicon in older adapters, wasting roughly 5% of energy as heat instead of 10-15%. That efficiency means smaller heat sinks and fewer internal components, so a 100W GaN charger can be a fraction of the size of an old-style 100W silicon laptop brick.
Can one GaN charger replace my laptop charger, phone charger, and tablet charger for travel?
Yes, for most modern USB-C laptops and phones. A 65-100W GaN charger with USB-PD support, like the Anker Prime 67W or UGREEN Nexode 100W in this roundup, can fast-charge a MacBook Air/Pro, an iPhone or Android phone, and a tablet: just note that output is split when multiple ports are used at once, so a laptop charges slower with other devices plugged in simultaneously.
Do GaN wall chargers work in other countries without a voltage converter?
Most USB-C GaN travel chargers from major brands, including Anker, UGREEN, Baseus, and Satechi, are built for a wide global voltage range (commonly 100-240V), so a simple plug-shape adapter is usually enough abroad. Always check the printed input voltage on your specific charger before traveling, since a few individual models have a narrower rated range.
What does PPS mean on a GaN charger, and do I need it?
PPS (Programmable Power Supply) is a USB-PD feature that enables adaptive fast-charging standards like Samsung’s Super Fast Charging. If you own a recent Samsung Galaxy or Google Pixel phone, look for a charger with PPS support: non-PPS chargers, like the budget Amazon Basics 100W pick in this roundup, cap those phones at slower charging speeds even though iPhones and laptops still charge normally.
Is a 4-port GaN charger better than a 3-port one for travel?
It depends on how many devices you travel with. A 4-port charger like the UGREEN Nexode 100W or Baseus GaN6 100W covers more devices at once (useful for couples or families), but is physically larger. A 3-port charger like the Anker Prime 67W is smaller and better suited to solo travelers charging a phone, laptop, and one more accessory.
The bottom line
Buy the Anker Prime 67W GaN 3-Port and leave three bricks and two cables at home. It’s the pick that changes what your bag weighs. Step up to the UGREEN Nexode 100W if two laptops travel with you, take the Baseus GaN6 100W if you want four ports that still fold, and treat the Amazon Basics 100W as the budget answer unless your phone is a Galaxy or a Pixel.
