Overview
A commuter or traveler gets two USB-C ports and two USB-A ports in one compact wall block. A smart chip adjusts the input power to the phone to reduce overcharging and overheating.
One block can replace several single-port chargers, and the pair gives a spare for the office or a bag. Output is capped as a total, so heavy use on every port means slower charging for each device.
Who it's for
Travelers and families with several small devices get multiple ports in a pocket-friendly body. Anyone who wants a high output single port for a notebook computer needs a larger charger.
Pros and cons
- Four ports in one compact block
- Both USB-C and USB-A outputs
- PD and Quick Charge 3.0 support
- Smart chip adjusts input power
- Total power shared across ports
- Plug type not listed
- Cable not mentioned in the package
Performance notes
Power Delivery and Quick Charge let the block negotiate faster rates with phones that support them. The total rating is split between ports, so output per port falls when several are in use. The smart chip trims input power to reduce heat on the phone side.
