* Power calculation: Watt = Voltage × Current. With adjustable profiles such as PPS and AVS, instantaneous power varies according to the voltage and current requested by the connected device and does not exceed the product’s total output limit. The “AVS: 9–20V ⎓ 2.25A [3A DPS]” statement on the 45W model is preserved as a technical reference based on the product label.
Technical Information Notice: The power profiles on this page are based on the technical label information shown on the products. Actual charging performance may vary depending on the protocols supported by the connected device, cable specifications, software, battery condition and temperature. USB, USB-C, USB Power Delivery, PPS, AVS and other third-party technology names may be trademarks or technical designations belonging to their respective owners and are used for informational purposes only.
