TOPADRE 100 W GaN, four ports, LED display, PD and PPS review

A four-port GaN charger with three USB-C and one USB-A, an LED display, and up to 100 W on any single USB-C port used alone.

By Jean-Benoit Buisson

The bottom line The only charger here that says which of its ports can carry the full output alone, with a display that makes the negotiation visible. Like all four multi-port chargers in this family, it never publishes the split between simultaneous devices.

A four-port charger that tells you more than its neighbours and still not enough.

The line that distinguishes it

Up to 100 W on USB-C1, C2 or C3 when used individually. Three chargers in this family have multiple ports and describe their sharing as intelligent; this one names which ports can carry everything. That turns a vague behaviour into a usable fact.

The display

An LED readout. USB-C charging is a negotiation between three parties and the outcome is normally invisible — a display makes it visible, which is how a limiting cable is identified.

PPS

Named in the title. Programmable Power Supply allows fine voltage steps rather than fixed jumps, which phones that support it use to charge faster and cooler. The range over which it operates is not published.

The lines still left blank

The split. Four devices at once, 100 W total, and no statement of how it divides. Every multi-port charger in this family has the same gap.

And a charge time quoted for a 14-inch MacBook Air without a model year, which makes it unreproducible.

German, French, Italian and Spanish Amazon stores quoted 27 € to 28 € when this page was compiled.

American and British Amazon stores returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

What it gets right, and what it leaves out

Strengths

It states that any of the three USB-C ports can carry the full 100 W alone, which no other charger here specifies
An LED display showing what is being delivered, which makes the negotiation visible
PPS is named, which is what allows fine-grained voltage control on phones that support it

Compromises

The split between four simultaneous devices is not published
A stated charge time for a specific MacBook is given without the model year
No cable mentioned

Questions owners ask about this one

What is PPS?

Programmable Power Supply: a Power Delivery extension that lets the charger adjust voltage in small steps rather than jumping between fixed levels. Phones that support it charge faster and cooler. Naming it is meaningful; not publishing the voltage range is the missing half.

Why does an LED display help?

Because USB-C charging is a negotiation between charger, cable and device, and the result is normally invisible. A display showing the delivered wattage tells you whether the cable is limiting things — which is the commonest cause of slow charging.
