PPS and Samsung Super Fast Charging
PPS sounds technical, but the buying rule is short: use a Samsung-approved 25W or 45W adapter plugged into a wall outlet. The sections below explain what PPS does and what Samsung says you need.
What is PPS?
PPS is a feature inside USB Power Delivery. Wikipedia says USB PD revision 3.0 defines it and that it allows granular control over the output voltage, in a range of 3.3V to 21V in 20mV steps, with current specified in 50mA steps. Samsung’s product page describes PPS as fast charging that adjusts voltage and current in real time.
The USB-IF says certified USB Fast Chargers support PPS, that PPS needs new hosts, devices and chargers to take full advantage, and that these chargers stay backwards compatible with USB Type-C and USB Power Delivery devices.
How does Samsung use PPS?
Samsung’s 45W adapter page says Super Fast Charging 2.0 requires a USB PD 3.0 compatible device supporting Direct Charging, and that devices without those features charge slower. The same page lists PPS at 5.0 to 20.0V for that adapter.
What do I need for Samsung Super Fast Charging?
Samsung’s support page gives three conditions.
| Requirement | What Samsung says |
|---|---|
| Adapter | A 25W or 45W Samsung-approved adapter |
| Phone | Super Fast Charging is only available on select devices, and not every device supports 45W |
| Outlet | Plug the adapter into a wall outlet, because a computer’s port makes charging slower |
Your device chooses the fastest speed it supports, so a bigger adapter does not force a faster charge.
What wired speeds do our Galaxy pages list?
The figures below are the wired wattage on each phone page. They describe what Samsung lists for the phone, not which phones use PPS.
| Wired figure | Samsung phones in our library |
|---|---|
| 25W | Galaxy S26, Galaxy Z Flip8, Galaxy A16 5G, A17 5G, A27 5G |
| 45W | Galaxy S26 Plus, S26 FE, A37 5G, A57 5G |
| 60W | Galaxy S26 Ultra |
Samsung’s support page names 25W and 45W adapters, so for the 60W S26 Ultra, open the phone page and check which adapter Samsung names. Our Galaxy S25 Ultra, Z Fold8 and Z Fold8 Ultra pages leave the figure blank because we could not verify a maximum wattage from Samsung, and we do not guess.
Will a PPS charger work with other phones?
Yes. The USB-IF says certified fast chargers are backwards compatible with USB Type-C and USB Power Delivery devices, so a phone that lacks PPS simply charges at the level it supports.
