Review · Travel adapter + GaN charger
Zendure Passport III: the crossover, done properly.
Most travel adapters change the plug shape and bolt on a token USB port. The Passport III is a genuine multi-port USB-C charger with international plug shapes wrapped around it.
Why the crossover category exists
Two objects — a plug adapter and your own GaN brick — is what our travel hub recommends by default. The Passport III puts both in one housing: retractable plug shapes outside, a multi-port USB-C PD charger inside. Zendure has shipped several Passport generations with different totals, so verify your revision on the listing; this page describes the class, which stays stable.
| Line item | Passport III class | Read on the listing |
|---|---|---|
| Rated output | 65W-class total — laptop watts, not token USB | The total and the single-port maximum |
| Port count | Multiple USB-C plus a USB-A, one budget | The split for the combination you will use |
| Protocol | USB-C Power Delivery with a 20V rail | Any PPS range, if a Galaxy travels with you |
| Form factor | Single body, retractable pins; grounded where the shape allows | Which shapes your revision includes |
| Notable feature | Plug adaptation and charging in one item | Whether there is a pass-through socket |
The structural point: a charger with plug shapes, not a socket with USB. That inversion is what makes it worth its price.
What it's genuinely good at
It actually charges a laptop. A conventional universal adapter's USB is phone-class at best. A 65W-class internal charger runs a MacBook Air, an XPS 13 or a ThinkPad at full speed — see the 65W class page.
One item to lose. For carry-on-only travellers that is the point — and one thing to unplug from a hotel wall, where adapters get abandoned.
Multiple ports. A phone, a laptop and earbuds from one hotel socket.
Where it falls short
It is still not a voltage converter, and no universal adapter is. Dual-voltage devices — every phone, laptop and camera charger — are fine at 230V; a 120V-only hair dryer is not: travel adapter vs converter.
Price and bulk. It costs several times a plug adapter plus a cheap GaN brick, and it is chunky in a wall socket. For one country, a flat adapter plus your own charger is more rational.
Shared budget. The 65W-class total splits across occupied ports, so a laptop plus a phone means the laptop steps down — same physics as any multi-port charger.
Not a high-wattage charger. A 16″ MacBook Pro wants 140W and will merely tick over, and no travel adapter solves that. Passport II, II Pro and III also differ.
Device fit
Full speed from one port: MacBook Air M-series, Dell XPS 13, ThinkPad ultrabooks, iPad Pro at 30W, Steam Deck at 45W, every iPhone, AirPods, Kindle. With the split in mind: laptop and phone together — the laptop steps down. Not served: MacBook Pro 16″ fast charge, Galaxy S25 Ultra at 45W without PPS, and any single-voltage appliance, ever.

FAQ
Is the Zendure Passport III a voltage converter?
No. It adapts the plug shape and passes voltage through — all a dual-voltage phone or laptop charger needs, but no help to a single-voltage appliance.
Can it charge a laptop?
Yes — the reason to buy it over a universal adapter. The built-in charger is laptop-class, not the category's usual phone-class USB.
Does the wattage get shared between ports?
Yes. The total is a shared budget, so a phone alongside a laptop makes the laptop port step down.
Is it worth carrying instead of a plug adapter plus my own charger?
Only if consolidating matters. The two-item kit is cheaper and easier to replace; this wins on one thing to pack.
