Eaton's USB Power Delivery Application Guide
Intelligent power on demand
What is USB power delivery?
The USB Power Delivery (USB PD) is a fast-charging technology based on the USB-C standard. It utilizes its high power output and an adjustable voltage supply to optimize charging based on your device's consumption needs. Whether you are charging your headphones or a laptop, the USB PD can safely and quickly recharge your device's battery.
Why is the USB power delivery receptacle rated in watts? Why not amps?
Standard USB devices (non-power delivery) use constant voltage (5V) to charge your device. Current is the only variable in this situation (1-5 Amps typically), so it makes sense to rate these devices in Amps.
A USB PD enabled device, however, can provide different voltages (5V-20V) based on the capacity and charging profile of your device. It can also vary its current similar to a standard USB device. As a result, it makes more sense to measure the charging capability of a USB PD device in Watts vs. Amps.
Rating the device in Watts also helps better correlate with power supplies of larger devices such as laptops.
Is USB power delivery technology safe?
A USB PD enabled device uses a “handshaking" approach to communicate with your device to supply the correct voltage and current.
USB PD enabled devices are also backwards compatible. This means that if a non-power delivery device is connected, a USB PD outlet will charge it based on the standard USB-C protocol.
As a failsafe, there is built-in overcurrent protection (4A) as well.
Does Eaton's USB power delivery receptacle allow data transfer?
Just like our other USB receptacles, our USB PD receptacles also do not allow data transfer and are solely used for charging purposes.
How does Eaton's Power Delivery USB receptacle stack up against a standard USB receptacle (non-power delivery)?
Power delivery USB - 60W total output rating
Visual description: Two wall receptacles are shown. The left receptacle (model TRUSBPDAC) features one Type-C port and one Type-A port, with labels indicating "Single port charging power Type-C 60W max." and "Type-A 12W max.". The right receptacle (model TRUSBPDC) features two Type-C ports, with a label "CLASS 2. TOTAL 60W".
Non-power delivery USB - 25W total output rating
Visual description: Two wall receptacles are shown. The left receptacle (model TRUSBAC) features one Type-A port, with a label "Single port charging power Type-A 12W max.". The right receptacle (model TRUSBC) features one Type-C port, with a label "Type-C 15W max.".

* Load testing done in engineering lab in 2023, only for models of electronic devices listed, with only one device plugged in to charge at a time unless otherwise noted. Charging times may vary based on number of devices charging, state of devices, quality of charging cords, and the age/condition of the battery.
