The Samsung Galaxy S20, S20 + and S20 Ultra are the first smartphones to receive certification for the new USB Power Delivery 3.0 standard. This means that the devices can also be charged with compatible third-party chargers with up to 45 watts.

As confirmed by the USB Implementers Forum today, the Samsung Galaxy S20, the S20 + and the S20 Ultra officially receive certification for USB PD 3.0 and support for programmable power supplies (PPS). This means that the devices should have no problem charging from third-party power supplies with 25 watts, or even 45 watts for the S20 Ultra, as long as the power supply can provide the necessary current and voltage.

USB Power Delivery 3.0 and PPS should allow smartphones to be charged even faster. However, it is not enough if a power supply unit only supports the correct wattage, the correct current and voltage must be able to be supplied, otherwise the device will charge much more slowly.

The Galaxy Note 10 Plus (from 959 euros on Amazon) also supports USB PD 3.0, even if it has not been certified for it. As reported by GSMArena, it can only be charged with 45 watts if a power supply supports 10V at 4.5A. However, this is a somewhat unusual claim, since USB PD only specifies 5V, 9V, 15V and 20V, so that most chargers would charge at 9V and 3A, i.e. with only 27 watts. With PPS, it would be possible for the power supply unit to communicate with the smartphone in order to be able to supply the perfect voltage.

At least that’s the theory. However, until third-party power supplies support these new standards and the appropriate voltages, it is still the safest method to use the power supplies recommended by the manufacturer to achieve the maximum charging speed.
