Review · Baseus · Multi-port GaN
Baseus 100W: the number on the box is a system total.
Baseus has shipped several 100W GaN desk chargers, and they share the thing that decides whether the product suits you: 100W is divided among the ports you actually use.
The specification that matters
Baseus revises this line frequently under different GaN generation names, so this review describes the class and the lines to read rather than a port table that may belong to last year's revision: disclosure.
| Item | What to expect in this class | What to verify on the listing |
|---|---|---|
| Rated output | 100W total across all ports | Labelled total, not per port |
| Single-port maximum | Usually the full 100W from the primary port, alone | The figure for your laptop's port |
| Ports | Two or three USB-C plus a USB-A | The split for two- and three-device use |
| Protocol | USB-C PD, commonly with PPS | A printed PPS band, and at what current |
| Form factor | GaN, wall-plug desk unit | Folding prongs; 100–240V input |
| Certification | UL or ETL mark expected | Printed on the housing, not only claimed |
Why GaN matters here: gallium nitride switches faster and wastes less heat than silicon, allowing 100W in a body you can leave in a power strip permanently: GaN chargers explained.
What this class is genuinely good at
One outlet, a laptop and two accessories: 100W lets a 14-inch MacBook Pro or a mainstream ultrabook take 60–65W while a phone and tablet take the rest. Like nearly every US-sold USB-C charger these accept 100–240V input, so one brick plus a plug adapter — not a voltage converter — travels: adapters versus converters.
Where it falls short, and who should skip it
The split is structural, not a flaw: plug a second device in and the primary port stops delivering 100W. A 16-inch MacBook Pro wants 140W alone, so a shared 100W leaves it slow whenever anything else is attached.
PPS here is common but not universal, and the current inside the band decides whether a Galaxy Ultra reaches 45W — never infer PPS from a high total. Listings are also frequently ambiguous about which revision they sell. Skip it if you need a full 140W for one machine, or want a port matrix you can rely on.
Which devices a 100W total actually serves
| Load | Outcome on a 100W shared budget |
|---|---|
| MacBook Pro 14″ alone | Full speed — 67–96W fits inside 100W |
| MacBook Pro 16″ alone | Charges, but below its 140W ceiling |
| MacBook Air alone or with a phone | Full speed; 30–35W leaves spare |
| Ultrabook (Dell XPS, ThinkPad, Spectre) + phone | Usually fine; most cap at 65W |
| iPad Pro + iPhone + earbuds | Well under the total |
| Galaxy S25 Ultra at 45W | Only if a PPS band around 11V at 4A or more is printed |
| Steam Deck + phone | Fine; the Deck asks for 45W |

Verdict
A 100W GaN multi-port unit suits most desks: a laptop plus two accessories from one outlet. Buy on a published port split and a printed UL or ETL mark, not the headline. If one machine needs the whole budget, read 140W adapters.

FAQ
Does a Baseus 100W charger give 100W from one port?
Typically yes when it is the only port in use, no once a second device attaches. Find the per-port distribution table first.
Will it fast-charge a Galaxy S25 Ultra?
Only if the listing prints a PPS band covering roughly 11V at 4A or more. High wattage does not imply a usable PPS profile.
Can I use it abroad?
If the housing states 100–240V input, yes, with a plug adapter for the socket shape. No voltage converter needed.
Is a GaN charger safe to leave plugged in?
A certified one is designed for it. Look for a UL or ETL mark on the housing — that, not the brand, is the safety signal.
