Features: - 35W power adapter with 2x USB-C Power Delivery connection - charges 2 devices simultaneously - fast charging - can be used worldwide - Input: 100-240V Technical data: - Input: 100~240V, 50/60Hz, 1.2A max. - Output USB-C1/ USB-C2: 5.0V/3.0A, 9.0V/3.0A, 2.0V/2.91A, 15.0V/2.33A, 20.0V/1.75A - Weight: 66g - Dimensions: 8.0 x 4.2 x 2.8cm GaN chargers and power banks are smaller than their silicon counterparts. This is also due to the fact that gallium nitride chargers/power banks do not require as many components as their silicon versions. Due to the lower heat during power transmission, less energy is lost through heat. The increased efficiency of GaN products also makes it possible to operate more powerful devices with smaller power supply units/power banks.
