Product Overview

Charges up to four USB-C devices at the same time from a single wall outlet. One port on its own delivers up to 100W, and all four ports together share up to 165W. GaN internals keep the housing small for that much output, the C7 power cord detaches from the back, and the included stand holds the charger upright with all four ports facing forward.

Setup

The 165W USB-C 4-Port PD GaN Charger is plug-and-play, no drivers or software required. USB-C charging cables are sold separately.

1. Connect the charger to a power outlet: Plug the included C7 power cord into the C7 power port on the charger, then plug the other end into a wall outlet.

2. Connect your devices: Plug your USB-C devices into the PD1, PD2, PD3 and PD4 charging ports.

Note: Satechi recommends certified USB-C charging cables. A port can only pass more than 60W through an eMark certified cable.

Ports and Features

Parts labeled diagram of the 165W USB-C 4-Port PD GaN Charger with 5 labeled components.

1. C7 Power Port: The figure-8 style C7 inlet where the included power cord plugs into the charger. Rated for 100V to 240V mains input.
2. C7 Power Cord (included): The AC power cord that runs from the charger to your wall outlet. It detaches from the C7 power port. This is the only cable in the box; USB-C charging cables are sold separately.
3. Desktop Stand: The included base that holds the charger upright on a desk with the four USB-C ports facing forward.
4. 4x USB-C PD Charging Ports: Four USB-C Power Delivery ports, labeled PD1 at the top through PD4 at the bottom. A single port on its own delivers up to 100W, and the four ports share up to 165W in total. Adding devices lowers the ceiling on each port, so plug the device that needs the most power into PD1 and check the table in Specifications for the exact split.
5. LED Indicator: The status light on the front of the charger, above PD1. The manual labels it but does not document its colours or what each state means.

Important Limitations

Emark cables required to reach wattage over 60W. Anything above 60W on a port needs an eMark certified USB-C cable. Cables are sold separately, so confirm the cable before expecting full speed.

Keep away from water, liquid, and moisture.

USB-C charging cables are not included. The box ships with the C7 AC power cord and the desktop stand only. Bring your own USB-C cables.

When using all four ports, connect your largest device to PD1. With all four ports in use the charger allocates 60W to PD1, 45W to PD2, 30W to PD3 and 30W to PD4, so the port you choose decides how fast a device charges.

Per-port wattage drops as you add devices. One device on its own can draw 100W. Two devices share 100W and 60W. Three share either 60W, 60W and 45W or 100W, 30W and 30W depending on which ports are used. Four share 60W, 45W, 30W and 30W. The full table is in Specifications.
