Do these multi-port GaN chargers interrupt charging when a new device is plugged in?

Yes, many high-output multi-port desktop chargers momentarily re-negotiate power distribution across all active ports when a new device is connected, which can cause a brief pause in charging.

Can high-output desktop chargers power a 16-inch MacBook Pro at full speed while charging other devices?

Depending on the total aggregate wattage and dynamic power splitting logic of the specific multi-port charger, single-port output may adjust dynamically as additional devices are connected.

Are desktop GaN chargers permitted in carry-on luggage by airlines?

Yes. Unlike lithium-ion power banks, wall-connected chargers do not contain internal batteries and are fully approved for airline carry-on and checked luggage worldwide.

Scenarios

The Dual-Laptop Road Warrior (Illustrative Modeling) (65% likely)
You travel with multiple laptops and mobile devices, demanding continuous high wattage across multiple active ports simultaneously. (Probability weighting is an illustrative user-adjustable modeling weight, not empirical.) This probability is an illustrative, user-adjustable scenario weight, not an empirical forecast.
The Hybrid Desk Setup & Travel Hybrid (Illustrative Modeling) (80% likely)
The charger lives primarily on a hotel desk or remote office, powering a laptop, tablet, earbuds, and phone all at once. (Probability weighting is an illustrative user-adjustable modeling weight, not empirical.) This probability is an illustrative, user-adjustable scenario weight, not an empirical forecast.
Minimalist Single-Device Traveller (Illustrative Modeling) (30% likely)
You pack light and rarely connect more than one laptop and one phone at any given time. (Probability weighting is an illustrative user-adjustable modeling weight, not empirical.) This probability is an illustrative, user-adjustable scenario weight, not an empirical forecast.

Pros & cons

Pros

High aggregate wattage eliminates the need to carry multiple separate power bricks for laptops and mobile devices.
Advanced GaN semiconductor technology ensures compact physical dimensions relative to legacy silicon power supplies.
Multi-port design consolidates desk clutter in hotel rooms or temporary remote workspaces into a single AC wall connection.

Cons

Desktop GaN bricks of high power tiers add weight and bulk to carry-on luggage compared to standard travel chargers.
Dynamic power redistribution logic can cause brief charging pauses on connected devices when a new device is plugged in or unplugged.
High thermal output can occur when operating at near-maximum capacity in poorly ventilated areas.

Assumptions

Simultaneous Laptop Charging (Illustrative Scenario Assumption): Two active USB-C laptops drawing 100W combined — Professional traveling workflows frequently require powering a primary work laptop and a secondary device or portable monitor.
Travel Frequency (Illustrative Scenario Assumption): Monthly flights and hotel stays — Portability, rugged build quality, and cord management are primary evaluation criteria for mobile professionals.
Thermal Operating Environment (Illustrative Scenario Assumption): Warm hotel rooms and enclosed desk spaces — GaN (Gallium Nitride) technology minimizes heat generation compared to silicon, but sustained high-wattage loads test thermal dissipation limits.
