USB-C Charger, 65W/61W USB Type C Power Adapter for Apple MacBook/Pro, Lenovo, Asus, Acer, Dell, Xiaomi Air, HP Spectre, Thinkpad etc. Prior to Power Delivery, mobile phone vendors used custom protocols to exceed the 7.5 W cap on USB-BCS. In a conventional battery charger topology a voltage supply is applied to a battery charge control circuit and the output of the system provides the proper voltage and current to charge the battery. The 45W charger is 10V 4.5A, so it needs to support the PPS protocol and the 10V4.5A charger to support it. Laptops or Smart Phones with The USB C ... as that would require a 10V/4A PPS PD protocol, which is not covered by most under-70 adapters. The QC4+ fast charge protocol is an extension of QC4.0, QC3.0, and QC2.0 within the framework of the USB PD 3.0 Programmable Power Source (PPS) protocol. The power is absolutely abundant, while it does NOT heat! [One Charger On the Go] Supporting PD3.0, PPS Protocol, built with 2 USB-C and USB-A charging port, Helpers Lab super charger is able to charge as many devices as possible in the market with the fastest speed. Notebook charging cannot reach 120W, because the upper limit of the PD protocol is 100W. The 2020 Moto G Power can be fast charged at 15W using a Motorola TurboPower charger, a Qualcomm QC3.0 charger, a Qualcomm QC4+ charger, or a USB-PD charger. Samsung finally upgraded the fast charging on the Galaxy Note 10 and Note 10 Plus this year. We found another blogger on Samsung China's forums testing the Note10+ out. The sink should check in with the source at least every 10 seconds with a voltage/current request. For Huawei mobile phones, the power cannot reach 40W, because the upper limit of the SCP protocol is 22.5W. The thing is that chargers can be PD3.0-compliant, but opt to use fixed voltages instead of utilizing PPS. Single type-c output port is 100W. Buy USB C Charger, Helpers Lab 105W 4-Ports Power Delivery Desktop Charger, Dual USB C PD 3.0 PPS Protocol Fast Charger for MacBook Pro, HP Dell XPS, iPhone, Note 10+ and More-Explore Edition: Chargers & Adapters - Amazon.com FREE DELIVERY possible on eligible purchases At the same time, because the current exceeds 3A, according to the USB-IF regulations, the charging cable also needs to be equipped with an emarker chip to be compatible. ... • Protocol Layer • Handles retries, message construction and chunking ... • PPS • Multi-port chargers • USB4 • Cables • Fast/Power Role Swap • Misc. A newly introduced PPS (Programmable Power Supply) protocol requires that a PPS-capable sink be able to request adjustments of source output voltage in increments as small as 20 mV. Means less wastage. A new design example report describes a 45 W USB PD 3.0 charger with 3.3 V–16 V PPS outputs using InnoSwitch3-Pro switcher IC and a Weltrend (WT6635P) USB PD controller.The ultra-efficient InnoSwitch3-Pro features digital micro-stepping of voltage and current for precise battery charge control, enabling this design to meet the PPS rapid-charging protocol while reducing system BOM. Likewise, the sink can request source current limits in 50-mA steps. • Added PPS for faster charging • PD as a sideband (Discovery, Alternate Modes, USB4 etc.) QC4+ chargers are USB-PD compliant. A great option to bring back the functionality of MagSafe and allows older users to recycle their old MagSafe adapters. Currently only Samsung original can be realized on the market. A common application requiring granular control of voltage and current, as offered by USB Programmable Power Supply, is the charging of batteries. On 8 January 2018 USB-IF announced "Certified USB Fast Charger" logo for chargers that use "Programmable Power Supply" (PPS) protocol from the USB Power Delivery 3.0 specification. The skinny is, you need a charger that does USB-C PD and PPS, as well as hitting 45W (or faster). [Advanced Safety Guarantee] Built with advanced protection system to protect from over-voltage, over-current, overheating or short circuits.
