Samsung · Protocol explainer
Super Fast Charging is just PPS with a marketing name.
Two tiers, one standard. Super Fast Charging is 25W of USB-C PPS; Super Fast Charging 2.0 is 45W of the same thing with a wider current allowance. Neither is proprietary, and that is exactly why so many chargers miss it.
The handshake, step by step
Plug a Galaxy into a USB-C charger and four things happen in under a second:
- The charger advertises its power data objects — a list of what it can supply. Fixed objects look like "9V at 3A". Programmable objects (APDOs) look like "3.3–11V, up to 4.05A".
- The phone reads that list and picks the object closest to its battery pack voltage, because the smaller the gap between supply voltage and cell voltage, the less energy is burned as heat inside the handset.
- It requests a specific voltage in 20mV increments and starts pulling current, adjusting the request continuously as the cells fill.
- The lock screen labels the result. "Super Fast Charging" means a PPS object was found and the 25W tier engaged. "Super Fast Charging 2.0" means the object also had the current headroom for 45W. Plain "Fast Charging" means no usable PPS was offered and the phone dropped to fixed-rail PD, typically around 15W.
The full standards background sits in the PPS guide and USB-C Power Delivery explained.
The three tiers, and who is in them
| Tier | Protocol | Devices |
|---|---|---|
| Adaptive Fast Charging, 15W | 9V/1.67A over USB-A, Quick Charge 2.0 derived | Galaxy S6–S10, Note 8/9, Tab A, budget A-series |
| Super Fast Charging, 25W | PD 3.0 + PPS to 11V at ~2.25A | Galaxy S20–S25 base, Z Fold, Z Flip, mid A-series |
| Super Fast Charging 2.0, 45W | PD 3.0 + PPS to 11V at 4.05A | S22+/S23+/S24+/S25+, all Ultra models, Tab S8–S10 Plus and Ultra |
Notice what is not on that list: wattage of the charger itself. A 240W desk brick with the wrong PPS objects sits in row one. A 45W brick with the right ones sits in row three. Wattage is a ceiling, not a qualification.
Chargers that satisfy each tier
- 25W
Samsung 25W Power Adapter
Tier two, guaranteed. The simplest way to get Super Fast Charging on a base Galaxy with no spec-sheet archaeology.

Where to go next: the 45W adapter in detail, the 25W adapter, the legacy 15W tier, PD vs PPS head to head, or the Samsung hub.
FAQ
Is Super Fast Charging a proprietary Samsung standard?
No. It is USB-C Power Delivery with the PPS extension, an open part of the USB-C specification. Samsung simply brands the two speed tiers it supports.
Why does my phone say 'Fast Charging' instead of 'Super Fast Charging'?
The adapter advertised no PPS profile the phone could use, so it fell back to a fixed PD rail at roughly 15W. Check the adapter's output block for a PPS line.
Does Super Fast Charging work over wireless?
Samsung uses the same marketing name for its 15W wireless standard, but that is an unrelated inductive protocol. PPS applies only to wired USB-C charging.
Will Super Fast Charging wear my battery out faster?
PPS is designed to reduce heat in the phone by moving voltage conversion into the adapter, and heat is the main driver of cell ageing. Charging overnight at low current remains gentlest.
