Samsung 2A, Adaptive Fast Charging (AFC), Super Fast Charging (SFC, SFC 2.0, SFC 3.0)

 

​Samsung implements several types of fast charging protocols: Samsung 2A, AFC, SFC, SFC 2.0, SFC 3.0.

​

Charging protocols:

  • Samsung 2A. 5V2A - 10W. Later was incorporated into the AFC protocol

  • AFC is a proprietary fast-charging technology developed by Samsung for its smartphones and tablets. Samsung's AFC is based on Qualcomm Quick Charge 2.0 and knows when to stop the charging process to extend battery life. AFC can deliver (5V2A, 9V/1.67A, 9V2A, 12V2A) up to 24Watts of power. However, Samsung devices compatible with AFC also work with the QC2.0 protocol. AFC protocol chargers usually work with UsbA-MicroUSB (5V2A) or UsbA-UsbC (5V2A, 9V/1.67A, 9V2A, 12V2A). For example, the official Samsung EP-TA300 charger supports 12V2A via AFC protocol.

  • SFC (Super Fast Charging) is based on PD PPS with a peak power of 25W(PD fixed voltage 9V/2.77A, PPS: 3.0 A(3.3-5.9 V) or 2.25 A(3.3-11.0 V)). SFC protocol requires a certified charger (or PPS support) and uses a standard UsbC-UsbC cable.

  • SFC 2.0 supports 45W peak charging with 5A UsbC-UsbC rated cable with e-maker chip (at least 100W nominal). SFC2.0 protocol requires a certified charger or a device supporting PPS with the corresponding voltage range and maximum current. Please note that to enable 45W charging in the PPS range up to 11V, a minimum current of 4.5A is required, as 45W is achieved at a voltage of 10V.

  • For S25 series smartphones (Plus and Ultra), SFC2.0 45W is also activated for PPS 15V3A.

  • The One UI 8.5 firmware for the future Samsung S26 smartphone series suggests the presence of Super Fast Charging 3.0 technology. There is speculation that at least the S26 Ultra version will offer charging at up to 60W.

  • SFC 3.0. Newer charging technology was introduced by Samsung together with the S26 smartphone series. It supports charging up to 60W. SFС 3.0 is basically the same as PPS 20V3A. SFС 3.0 is supported by smartphones Samsung S26 Ultra (60W - 20V3A) and S26 Plus (45W - 20V2.25A).

 

Notes:

  • Together with SFC, Samsung smartphones support the PD PPS charging protocol.

  • Sometimes, SFC protocol is called SSFC, which stands for Samsung Super Fast Charging.

  • You may find chargers that support this protocol here

➡️If you need a charger with tested load performance and confirmed support for charging protocols, check this selection of charging adapters.

​​

➡️If you need a USB-C cable for device charging or high-speed data transfer, take a look at the tested cables with measured internal resistance and e-marker chip data.

Implementation of charging protocols SFC2.0/3.0 ​​in some Samsung products:

Tablets:

  • Galaxy Tab S7+ supports SFC2.0 (PPS 11V5A) - 45W

  • Galaxy Tab S8 series support SFC2.0 (PPS 11V5A) - 45W.  Real charging speed for Tab S8 is up to 34W, it also supports charging using PD fixed 9V with real charging speed up to 14W.

  • Galaxy Tab S10 FE+ supports the SFC2.0 (PPS 11V5A) protocol - 45W. There is no reliable confirmation of PPS 15V3A support.

 

Smartphones:

A-series:

  • Galaxy A56 and Galaxy A37 support SFC2.0 (PPS) (up to 9.6V3.8A) - 34W max in real tests, most often - 27W, including from original chargers. It also supports fixed PD protocol: (5V3A, 9V3A) up to 14W.

  • Galaxy A57 and Galaxy A37 support the SFC2.0 (PPS 11V5A) protocol - 45W.

S-Series:

  • Galaxy S20 Ultra supports SFC2.0 (PPS 11V5A) - 45W

  • Galaxy S21 Plus/Ultra supports SFC - 25W (this is not a typo! 25W max)

  • Galaxy S22, S23, S24, and S25 (base versions) smartphones support a maximum power of 25W for wired connections and 15W for wireless connections.

  • Galaxy S22, S23, S24, and S25 (Plus and Ultra versions) support a maximum power of 45W for wired connections and 15W for wireless connections. However, to activate 45W, the S22, S23, S24, S25 models (Plus/Ultra) require PPS/SFC2.0 mode supporting 10V4.5A (China Quality Certification Center (CQC) specifies 11V4.05A) and a cable supporting 5A (100W/240W). The S25 Plus/Ultra series smartphones can also be charged using different PPS operating modes up to 16V3A, which reduces the cable requirements to 3A (i.e., any USB-C to USB-C cable), but the charger must support this PPS operating mode.​​

  • Galaxy S25 FE smartphone supports 45W charging, but it is not yet known on which PPS/SFC2.0 voltage range. Most likely, 45W is achieved under the same conditions as for the S25 Plus/Ultra - PPS up to 16V3A.

  • Galaxy S26 Ultra (SM-S9480) supports 60W PPS (SFC 3.0) charging and next charging modes: 5V2A, 9V1.67A, 9V2.77A, 10V4.5A, 15V3A, 20V3A (real charging power is around 54W)

  • Galaxy S26 Plus supports PPS (SFC 3.0) 45W - 20V2.25A (and older SFC 2.0 charging modes 15V3A, 10V4.5A)

  • Galaxy S26 supports PPS (SFC) (up to 24W or real charging power) and PD 9V3A (up to 21W of real charging power)​

Fold-series:

  • Galaxy Z Fold6, Fold7, Z Flip7, and Z Flip7 FE smartphones only support up to SFC 25W (9V2.77A)

  • Galaxy Z Fold8 (SM-F9710 and the SM-F97060) supports up to SFC2.0 (or SF3.0) 45W (not clear yet at which voltage)

Note-series

  • Galaxy Note 10 Plus supports SFC2.0 (PPS 11V5A) - 45W​
