Question 1

What devices does a 100W desktop charger support?

Accepted Answer

A 100W desktop charger supports all USB-C PD laptops including MacBook Pro 16”, MacBook Air, Dell XPS 15, HP Spectre x360 16”, ASUS ProArt Studiobook, and Lenovo ThinkPad. It also charges iPhone, Samsung Galaxy, iPad Pro, and tablets at full speed from any remaining ports simultaneously.

Question 2

Is 100W safe for MacBook Pro 16"?

Accepted Answer

Yes. Apple recommends 96W–140W for the MacBook Pro 16” — a 100W PD 3.1 charger is the perfect desk companion. It will charge the MacBook Pro 16” at full speed during normal use. Our SmartGear 100W desktop charger uses USB Power Delivery 3.1 which supports up to 100W on a single port.

Question 3

How many devices can a 100W desktop charger power at once?

Accepted Answer

Multi-port 100W desktop chargers can power 3–4 devices simultaneously. When multiple ports are in use, power is intelligently distributed — for example, 65W to a laptop + 20W to a phone + 15W to earbuds, all from one charger. The total output stays at 100W regardless of how many ports are active.

Question 4

What is the difference between a 65W and 100W GaN charger?

Accepted Answer

A 65W charger is compact and portable — ideal for MacBook Air, 13”/14” laptops, and phones. A 100W desktop charger delivers the extra power needed for 15”/16” laptops (MacBook Pro 16”, Dell XPS 15) at full speed. The 100W unit typically has 3–4 ports vs 2–3 on a 65W model, making it better for desk setups with multiple devices.

Question 5

Do I need a special cable for 100W charging?

Accepted Answer

For 100W USB-C Power Delivery you need a USB-C to USB-C cable with an E-marker chip, rated for 100W or 240W. Standard USB-C cables without an E-marker are capped at 60W. Our SmartGear 240W USB-C E-marker cable is rated well above 100W and is available separately or bundled with every desktop charger.
