Mfish 140W USB C Charger 4-Port GaN Block - Foldable Fast Laptop

In this review the Mfish 140W USB C Charger is presented as a compact, multiport power hub aimed at people who need serious charging speed in a small package. Its single biggest selling point is the combination of the PD 3.1 140W output and a foldable plug, which delivers fast laptop charging while remaining travel friendly. The reviewer found it most compelling for owners of modern MacBook and Windows laptops who also want to top up phones and tablets without carrying multiple adapters or a bulky power brick.

Key Features

• PD 3.1 140W Super Fast Charging: Can take a MacBook Pro 16' from 0% to about 56% in roughly 30 minutes, useful for rapid top ups before meetings or flights.
• Dual-port simultaneous charging: The block supports a 100W max laptop plus a 20W phone at the same time, letting a laptop and phone share power without slowing essential devices excessively.
• Compact GaN design and foldable plug: Gallium nitride electronics and a foldable plug shrink the charger by about 30% versus older 140W bricks, making it easier to pack for travel.
• Four-port versatility: Three USB-C ports and one USB-A port let users power two smaller laptops and a phone or tablet concurrently, reducing desk clutter.
• Advanced temperature control: Mfish-ICE 2.0 improves heat dissipation and runs extensive overload tests, which helps protect devices during sustained high-power use.

Who It's For

This charger is best for frequent travelers, remote workers, and anyone who carries a modern laptop and one or two mobile devices. Owners of MacBook Pro or Air and contemporary Windows laptops will appreciate the high single-port wattage and the ability to rapidly replenish battery when time is limited.

Users who require the absolute highest sustained charging speed on some Dell models should check compatibility first, since certain Dell charging protocols may prevent full-speed charging. If you need a dedicated single-output 140W brick without multiport sharing, a single-output charger may still be preferable.

Pros & Cons

Pros

• Very fast PD 3.1 charging that supports rapid top ups for 16' MacBook Pro-class laptops.

Cons

• Some laptops, notably certain Dell models, may not charge at full advertised speed due to their own charging protocol limitations.
• Functionality reports are mixed among users, with a few saying it failed to work in isolated cases.
