What is Fast Charging?
For starters, fast charging is a term used for chargers and devices that are capable of charging faster than regular USB speeds (5W). It is usually done by dynamically increasing the current supply or voltage flow to the battery.
While fast charging helps the phone juice up faster, it also has a disadvantage. The increased power supply generates heat, which tends to degrade the battery in the long run.
Types of Fast Charging Technologies
Earlier, the companies used to rely on the charging technology offered by the chipset maker. However, several brands have now started implementing their own proprietary charging standards.
Qualcomm QuickCharge
Qualcomm processors are used by almost all major smartphone companies across the globe. This makes QuickCharge one of the most common types of fast charging technology for phones powered by Snapdragon SoCs.
The recently launched QuickCharge 3+ supports Snapdragon 765-series chipsets aimed at upper mid-range phones. Whereas, the advanced QuickCharge 4+, which is also compatible with Power Delivery, is reserved for flagship devices. The QuickCharge 3.0 can usually be found on some older flagships.
The newer QuickCharge versions are also backward compatible with older standards. So, chargers based on the new standard can still fast-charge older devices. That said, having a Snapdragon chip doesn’t guarantee that the phone will support Quick Charge.
| Max Voltage | Max Current | Max Power | |
| QuickCharge 1.0 | 5V | 2A | 10W |
| QuickCharge 2.0 | 5V or 9V or 12V | 1.67 or 2A | 18W |
| QuickCharge 3.0 | 3.6-20V dynamic | 2.5 or 4.6A | 18W |
| QuickCharge 4.0+ | 3.6-20V dynamic | 2.5 or 4.6A | 100W |
| QC 4.0+ (USB-PD) | 5V or 9V | 3A | 27W |
Charging Speed: Up to 50% in 15 minutes (QC 4+)
Supported Phones: Xiaomi Mi 9, Mi 8-series, LG V40, Redmi Note 9 Pro, Redmi K20-series, Samsung Galaxy A70, Galaxy A80, Poco F1, and more. Check this list to see if your phone supports QuickCharge technology.
USB Power Delivery (USB PD)
USB Power Delivery is a universal fast charging standard that works across USB Type-C to Type-C ports. One can charge not only smartphones but also other accessories and devices, including compatible laptops. It employs data protocol to communicate between the charger and device to ensure the flow of required power.
Interestingly, the Qualcomm Quick Charge 4+ also supports USB PD. So, if your device doesn’t have Quick Charge but employs Power Delivery, you can still use a Quick Charge-enabled charger to speed up charging.
Google’s Pixel series uses USB Power Delivery as the primary charging technology, with the bundled charger supporting 15W. Similarly, if you have an iPhone 8 or newer model, it can be charged at up to 50% in around 30 minutes with a PD charger.
Charging Speed: Varies across devices
Supported Phones: Google Pixel 2, Pixel 3, Pixel 4-series, iPhone 8, 8 Plus, iPhone X, XR, XS, iPhone 11-lineup, Samsung Galaxy S20, Galaxy Note 10, etc.
MediaTek Pump Express
MediaTek is another company that makes processors for mobile phones. Like Qualcomm, MediaTek-powered phones are bundled with the company’s Pump Express charging technology.
The latest Pump Express 4.0 supports up to 5A of current over USB Type C interface. It is fully compatible with USB Power Delivery 3.0 and offers good efficiency and heat management. However, it isn’t as fast as other standards.
| Max Voltage | Max Current | Max Power | |
| Pump Express 2.0 | 5V | 3A | 15W |
| Pump Express 3.0 | 3-6V | 5A+ | 30W |
| Pump Express 4.0 | 3-6V | 5A+ | 30W |
Charging Speed: Up to 70% in 20 minutes (PE 3.0, 4.0)
Supported Phones: Redmi Note 8 Pro (also supports QC 4.0+, PD 3.0) and more.
Samsung’s Adaptive & Super Fast Charging
Samsung has been using its own Adaptive fast charging solution based on QuickCharge 2.0 in Galaxy-series. However, the mere 15W technology got far behind the standards used by Chinese companies.
Finally, Samsung moved on to Super Fast Charging with Note 10 and S20-lineup. This technology delivers 25W of power over Power Delivery and PPS. Nevertheless, Samsung does sell a 45W adapter, which works particularly with S20 Ultra and Note 10 Plus.
What is PPS? PPS or Programmable Power Supply is a new addition to PD 3.0 that allows the charger to input variable voltage instead of typical fixed levels of 5V, 9V, 15V, and more.
| Max Voltage | Max Current | Max Power | |
| Adaptive Fast Charging | 5V/ 9V | 1.67/2A | 15W |
