The RAVPower PPS fast charger is designed for the iPhone 12 series and is MFi certified. Also, it has a total power output of 30W and 2 ports: a 20W USB-C port and 10W USB-A port. The USB-C port features PD 3.0 fast charging and can charge an iPhone 12 from 0% to 50% in about 30 minutes. The power adapter comes with an MFi-certified USB-C to Lightning cable. 3 RAVPower Chargers Which Support PD and QC Charging

Ever since the introduction of the USB Type-C interconnect model in 2014, the 3.0 has taken on a more effective, adaptable, and efficient form that overturns any structural flaws that existed in the past.INOV works by intelligently detecting the exact amount of voltage required by your device. This is a significant improvement from QC 2.0, which offered four different modes. By detecting the precise voltage your device needs, QC 3.0 provides two significant benefits. First off, it maximizes your charging performance. For instance, if your device requires an unusual voltage like 19 volts, the charger will deliver it. You won’t be left flat by a 12 or 18-volt charge. Secondly, the technology avoids any wastage. You won’t be feeding 20 volts of power to a 19-volt device. Not only does is avoiding waste good for the environment, it’s also good for your device. Excess energy is shed as heat, which can cause damage. By avoiding this, QC 3.0 prevents overheating. Which is Faster? Fast charging allows for optimized charging in the early stage of charging; meaning, you get an improved battery capacity after a short period of charging. Companies do not boast of a full fast charge because power transfer in the concluding stage of charging drops. These chargers were used on two sink devices: a new PD 3.0-ready mobile phone and a PD 2.0-ready mobile phone. As seen in Table 3, the time to full charge for matched PD 3.0 source and sink devices was 60 minutes compared to 80-90 minutes for the same phone when charged with PD 2.0 compliant sources. At the 60-minute mark, the PD 2.0 capable chargers had reached 80% of full charge and required 20 and 30 minutes, respectively, to complete charging. For the earlier model phone, charge times were identical for the all three source devices. The difference between the two types of PD charging lies in the amount of detailed information given by each.USB PD 3.0 has worked to improve its power delivery but is primarily known for offering increased amounts of information about the device being charged and its power/ battery. This includes reporting any malfunction or system change within the device, temperature of the device, or what may be causing hold ups or decreased charging speed, etc. For example, if an over-current or over-voltage occurs while charging, your device will notify you with a data message of the mishap.

Apple, for instance, uses the USB- PD fast charge for its iPhone XS, iPhone XS Max, iPhone X, iPhone 8, and iPhone 8 Plus. Sometimes you need a big power boost, not just a little, especially when there’s a power outage, and that’s where the RAVPower Power House comes in. If you want a charger that can power a laptop, tablet, smartphone and a console, this is it. You won’t have any problems charging your devices to full capacity multiple times. And we’re talking about mainstream devices here, like the MacBook Pro, the Samsung Galaxy S20 Ultra, and the iPhone 12 Pro Max. Since the creation of the USB PD fast-charging standard, changes have been made exponentially, bringing a variety of updates, functions, and features that get better with each release. The PD 2.0 specification allows the source (charger) to provide fixed voltages such as 5, 9, 12, 15, and 20V at a maximum allowable current to the sink (mobile device). efficiently. Get One of These Two RAVPower PPS Fast Chargers 1. PD Pioneer 20W Wall Adapter (RP-PC150)The power adapter also has safety features and protects your devices as it juices them. They are safe from overvoltage, short-circuiting, and overheating. In addition, it pushes 61W of power and can charge iPhones two hours faster than other chargers. But you need a USB-C to USB-C cable to activate the QC technology. 2. PD Pioneer 20000mAh 60W 2-Port Power Bank (RP-PB201) When operating in constant voltage (CV) mode, the source strives to maintain a constant voltage output across V BUS, even as the V BUS load current changes. However, the V BUS load current must also remain within the operating current requested in programmable RDO. If the V BUS load current increases beyond the requested operating current, the source switches to constant current (CC) mode.

So, which is faster, PD 3.0 or QC 3.0? In a nutshell, it depends on your device. To begin with, there’s a difference between Android and Apple products. With Android, you’re dealing with an open standard, so your mileage may vary. Most newer Android phones support PD charging, and more than half also support QC 3.0. This includes newer Samsung models. Keep in mind, though, that this will depend on your phone’s manufacturer. If you’re using a cheaper phone like an LG Stylo, you’re still limited to Micro USB charging. This won’t allow for either PD 3.0 or QC 3.0. While looking at various electronic devices, you may have seen the term “fast charging”. What does this have to do with PD 3.0 or QC 3.0? In a word, nothing. It’s simply a measurement of how fast a battery can charge. In general, a standard 1 amp charger charges at 5 watts, which is ordinary USB. Conversely, fast charging batteries can charge at 12 watts or higher. Table 3 Charging times are compared between PD 3.0 and PD 2.0 ready mobile devices. Source: Infineon PD is short for “power delivery”. The technology is capable of delivering up to 100 watts of power, far more than any smartphone requires. However, this high wattage has some significant advantages. For instance, it can be used to power laptops. Apple’s new MacBooks all use it, and can even be used while they’re charging. This means you’re getting much better performance than you’d expect from a standard USB cable. Figure 1 The diagram shows voltage vs. current charging of lithium-ion battery cells. Source: Infineon

USB PD Programmable Power Supply (PPS) explained

Voltcraft CQCP2400 operating instructions" (PDF) (User manual). Voltcraft. Output voltage/current 5 V/DC, max. 2400 mA or 9 V/DC, max. 1670 mA or 12 V/DC, max. 1250 mA As the cells are charged, the sink periodically renegotiates with the source to increase or decrease voltage and/or current. During each power transition, the sink is required to reduce power consumption to 2.5 W (pSnkStdby) until the source accepts the request and sends first an Accept and then a PS-RDY message.
