What is PPS, and does your phone need it?
PPS lets a phone fine-tune the charging voltage. Some Android phones, including many Samsung models, need it to reach their fastest speeds.
PPS (Programmable Power Supply) is an optional part of USB Power Delivery. Standard PD offers a handful of fixed voltages, like 9V or 20V. PPS lets the device request a voltage in small steps within a published range, for example anywhere from 3.3V to 11V.
Why fine-tuning matters
Converting voltage creates heat inside the phone. With PPS, the phone can ask the charger for almost exactly the voltage its battery needs at that moment, so less conversion happens inside the phone. That lets some phones charge faster without overheating.
Which devices use it?
Many Samsung Galaxy phones use PPS for their “Super Fast Charging” modes, and some other Android phones use it too. Without PPS, these phones still charge over standard USB PD, but usually more slowly.
iPhones and most laptops don’t depend on PPS.
Reading PPS specs
Manufacturers publish PPS as ranges, such as “3.3–11V ⎓ 3A” (up to 33W) or “3.3–21V ⎓ 3.25A”. A phone’s fastest mode needs a range that covers both its voltage and its current. For example, a 45W mode needs more current than a 25W one, and often a 5A-rated cable.
Some product pages list PPS without the range, and we show that as “range not published.” If PPS isn’t mentioned at all, we mark it not published, which isn’t the same as “not supported.”
Wattson’s take: I couldn’t verify every charger’s PPS range, so I won’t promise maximum Samsung charging speed unless the range is published. When in doubt, check your phone maker’s charger recommendation.
