The Manufacturer
Ravpower is trademarked by Sunvalleytek International.
Charging a Device using a USB Port
The charger is first plugged into an AC outlet and then connected, via USB cables, to the devices being charged. This type of charger generates 5-volts DC with an output varying between .1 to 2.4 amps, although, if equipped with USB-C PD ports, amperage and voltage can be higher. Many modern USB chargers automatically identify connected devices and their unique charging requirements.
Power Delivery
This specification denotes higher power capabilities, allowing USB-C PD-enabled devices to charge quickly over a USB connection. The two coupled devices negotiate a power contract, determining how much power will be pulled from the charger. Output voltages begin at the 5V setting but are configurable up to 20V. The charger’s output can rise as high as 65 watts. Power Delivery allows for power to flow in both directions. If, for example, you were to use a USB cable to connect two Power Delivery supported phones together, one phone could be used to charge the other.
The GaN Charger
Gallium nitride is a semiconductor material that rose to prominence in the 1990s through the manufacture of LEDs. This crystal-like substance enjoys a wider bandgap than its silicon rival. A broader bandgap allows energy to pass through more efficiently, resulting in lower operating temperatures and higher power limits.
Compatibility
This charger is equipped with two 5VDC USB-A ports. They can provide an output of 5 volts at 3 amps, 9 volts at 2 amps, and 12 volts at 1.5 amps. Two USB-C PD ports are also fitted. They can provide an output of 5 volts at 3 amps, 9 volts at 3 amps, 12 volts at 3 amps, 15 volts at 3 amps, and 20 volts at 3.25 amps. However, to take advantage of the Power Delivery system, the device being charged must be PD enabled.
Charging Multiple Devices
The RP-PC136’s maximum power output is 65 watts. The power available at each port drops as devices requiring a charge are plugged into the unit. Walter B Shillington Walter B Shillington For example, a PD-enabled Windows laptop that required a 20V input would probably consume the charger’s entire 65-watt output. If a MacBook were plugged into both PD ports, 45 watts of power would be distributed to the first laptop and 15 watts of power to the second. If a set of earbuds and a Kindle were connected to the two USB-A ports, they would output 5V at 2.4 amps, and the remaining 36 watts would be distributed evenly between the pair of USB-C PD outputs.
Overall Impression
This charger can output up to 65 watts without generating excess heat and is equipped with two USB-A ports and two USB-C Power Delivery ports. It is small, lightweight, and well constructed. Walter B Shillington If you own a PD-enabled laptop, tablet, or phone, you will find Ravpower PD Pioneer 65W Desktop Charger to be a valuable addition to your office.
