PinePower 120W desktop power supply features display, USB PD, QC 3.0 and wireless charging

Desktop Power Supply Qi Wireless Charging

Pine64’s January update includes the launch of PinePhone with Mobian operating system, some limited details about the upcoming Quartz64 RK3566 SBC that will ship with 4 to 8GB RAM, and other news about all their products. There’s not enough details yet to write a post about Quartz64, but another product caught my eyes: PinePower. Yes, Pine64 is now offering power supply, and last month they presented PinePower 65W GaN power adapter that looks similar to MINIX NEO P1 power supply, albeit slightly larger. But I find the desktop version of the power supply even more interesting with an integrated display that shows voltage and current for each port, and also adds Qi wireless charging. PinePower “Desktop” version specifications: Display – Shows individual port voltage and current status USB charging ports 1x USB Type-C PD port up to 65W output with support for 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A 1x QC 3.0 […]

MINIX NEO P1 tiny 66W GaN USB-C power supply can handle up to 3 devices

I’m now using MINIX NEO P2 GaN USB-C charger for all review using USB powered devices. But with four-ports and up to 100W of power, it’s a bit over-powered for one or two Raspberry Pi 4 or equivalent SBCs, and it also costs around $60. So the Hong Kong company has now introduced a new model with MINIX NEO P1 being a tiny 66W GaAN USB-C power adapter with two USB-C ports and one USB Type-A port and international plug adapters that make ideal to use on the go. MINIX NEO P1 key features and specifications: Power Input – 100-240V AC input with 2-prong US plug and adapters for EU, UK, and AU Power Output Up to 66 W in total 2x USB Type-C ports support up to 65 W with USB PD 3.0 (5-15V/3A, 20V/3.25A) 1x USB Type-A port supports up to 36 W with QC 3.0 (5V/3A, 9V/3A, […]
