Will the Maxpower TF880XJ charge my 16-inch MacBook Pro at full speed?

Yes, the Maxpower TF880XJ can deliver up to 140W from its USB-C1 or USB-C2 ports, which is sufficient to fast-charge a 16-inch MacBook Pro at full speed. However, you must use a compatible 140W-rated USB-C to MagSafe 3 cable or a 5A USB-C to USB-C cable to achieve this maximum output.

Why does my device stop charging for a second when I plug in a new device?

The Maxpower TF880XJ uses a smart power distribution chip that briefly pauses charging to safely recalculate and redistribute the 140W total power whenever a new device is plugged in or unplugged. This is a standard safety feature in multi-port GaN chargers to prevent over-current issues.

What is PD 3.2 AVS and why is it important for the iPhone 17?

PD 3.2 AVS (Adjustable Voltage Supply) is the latest Power Delivery standard that allows the charger to finely tune the voltage in real-time based on the device's battery temperature and capacity. This ensures faster, safer charging with less heat generation, which is the required standard for upcoming flagship devices like the iPhone 17.

Does this charger come with a UK plug suitable for Hong Kong?

Yes, the Maxpower TF880XJ includes a detachable UK-style (Type G) AC power cord inside the box, making it perfectly safe and ready to use in any standard Hong Kong wall socket right out of the packaging.

Can I bring this 140W desktop charger on an airplane?

Absolutely! The Maxpower TF880XJ is a power adapter, not a power bank with an internal lithium battery. Because it does not store energy, there are no airline restrictions against packing it in your carry-on or checked luggage for international travel.
