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

 

Samsung uses several fast-charging technologies: Samsung 2A, AFC, SFC, SFC 2.0, and SFC 3.0.

​

Charging protocols:

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

  • AFC is Samsung's proprietary fast-charging technology for smartphones and tablets. A typical Samsung AFC mode is 9V1.67A (15W); compatible Samsung devices can also work with QC2.0. Some Samsung adapters supported higher-power modes: for example, the EP-TA300 with AFC provides up to 12V2.1A, or about 25W.

  • SFC (Super Fast Charging) uses USB PD 3.0 with PD PPS and supports up to 25W. Typical profiles of Samsung's original 25W adapter are PD 9V2.77A; PPS 3A (3.3-5.9V) or 2.25A (3.3-11V). SFC requires a compatible USB PD/PPS adapter; a standard 3A USB-C - USB-C cable is sufficient for 25W.

  • SFC 2.0 supports charging up to 45W. For the 45W mode with PPS up to 11V, current up to 4.5A is required, so a 5A USB-C - USB-C cable with an e-marker is needed. A compatible adapter must support USB PD/PPS with the required voltage and current range.

  • For Galaxy S25 Plus and Ultra, 45W SFC 2.0 can also operate with a PPS range reaching 15V3A.

  • SFC 3.0 was introduced with the Galaxy S26 series. Galaxy S26 Ultra supports Super Fast Charging 3.0 up to 60W. The same charging performance can also be achieved with a third-party USB PD PPS charger that does not explicitly advertise SFC 3.0, provided its PPS range reaches approximately 20V and supplies the required current. Galaxy S26+ supports charging up to 45W, while Galaxy S26 supports up to 25W.

 

Notes:

  • Samsung's SFC, SFC 2.0, and SFC 3.0 modes do not require a charger to carry the corresponding Samsung SFC designation. A standard USB PD PPS charger can provide the same charging performance if it supports the voltage and current ranges required by the device.

  • SFC is sometimes referred to as SSFC, which stands for Samsung Super Fast Charging.

  • You can find charging adapters that support these protocols here.

➡️ If you need a charger or power bank 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 SFC 2.0/3.0 protocols in selected Samsung products

Tablets Galaxy:

  • Tab S7+ supports SFC 2.0 (PPS 11V5A) - 45W

  • Tab S8 series support SFC 2.0 (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.

  • Tab S9, Tab S9+, Tab S9 Ultra, Tab S9 FE, Tab S9 FE+ supports the SFC 2.0 (PPS 11V5A) protocol - 45W

  • Tab S10+, Tab S10 Ultra, Tab S10 FE, Tab S10 FE+ supports the SFC 2.0 (PPS 11V5A) protocol - 45W

  • Tab S11, Tab S11 Ultra supports the SFC 2.0 (PPS 11V5A) protocol - 45W

 

Smartphones:

A-series:

  • Galaxy A55, A54, A35, A34, A27, A26, A25, A24, A17, A16, A15, A06, A05 support SFC 25W

  • Galaxy A56 and Galaxy A36 officially support SFC 2.0 charging up to 45W. In real-world tests, charging power reaches approximately 34W but is often around 27W, including with original Samsung chargers. Fixed PD (5V3A, 9V3A) is also supported, with real charging power up to approximately 14W.

  • Galaxy A57 and Galaxy A37 support the SFC 2.0 (PPS 11V5A) protocol - 45W.

S-Series:

  • Galaxy S20 Ultra supports SFC 2.0 (PPS 11V5A) - 45W

  • Galaxy S21 Plus/Ultra supports SFC - 25W (not a typo, 25W is the actual maximum)

  • 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/SFC 2.0 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 - USB-C cable), but the charger must support this PPS operating mode.

  • Galaxy S23 FE supports PPS/SFC charging up to 25W

  • Galaxy S24 FE supports PPS/SFC charging up to 25W (specs)

  • Galaxy S25 FE supports SFC 2.0 charging up to 45W.

  • Galaxy S25 Edge supports PPS/SFC charging up to 25W

  • Galaxy S26 Ultra supports SFC 3.0 charging up to 60W.

  • Galaxy S26+ supports SFC 2.0 charging up to 45W; Samsung specifies 10V4.5A or 15V3A operating modes.

  • Galaxy S26 supports SFC charging up to 25W with a 9V2.77A mode.

  • Galaxy S27 series with a very high probability (mentioned in the Chinese 3C certification database) will have the next charging capabilities: Galaxy S27 (SM-S9520) - 45W, Galaxy S27 Plus (SM-S9650) - 27W, Galaxy S27 Pro (SM-S9570) - 60W, Galaxy S27 Ultra (SM-S9580) - 60W

Fold-series:

  • Galaxy Z Fold5, Fold6, Fold7, Flip6, Flip7, Flip8, Flip7 FE smartphones only support up to SFC 25W (9V2.77A)

  • Galaxy Z Fold8 (SM-F9710), Fold8 Ultra supports SFC 2.0 charging up to 45W - 15V3A.
