This is the best power bank for your Galaxy S20 Ultra – super fast charging 2.0 with USB PD 3.0 and PPS «Android :: Gadget Hacks



When Samsung announced that its new Super Fast Charging 2.0 system was based on USB PD, the industry was delighted. Using an open standard, Galaxy users can choose from hundreds of third-party chargers in addition to Samsung's first-party options. The problem is that this never came to fruition.

The big hurdle is the fact that Samsung's Super Fast Charging 2.0 (SFC 2.0) chargers must support two standards: USB Power Delivery 3.0 (USB PD 3.0) and Programmable Power Supply (PPS). USB PD 3.0 is fairly easy to get, but finding a charger or power bank with it and PPS is another story.

While USB PD 3.0 allows supported devices to use fixed voltage levels for charging (z, 5V, 9V, 1

5V), PPS allows the power supply to communicate with the charging port and battery to measure voltage and dynamically adjust the current based on the current conditions. In this way, the charger can ramp up to higher voltages in higher conditions and then slow down when the battery needs to cool down.

So it makes sense that Samsung needs both standards, but the fact remains that there aren't many power banks that support both. In fact, I searched the internet for one for my S20 Ultra pre-order and found only one:

At $ 59.99, it's expensive, but only $ 10 more than the 45-watt power brick from Samsung. However, this is a portable power bank that allows you to charge your Galaxy S20 Ultra four times before it needs to be charged. And with Super Fast Charging 2.0, your S20 Ultra can be charged from 0% to 100% in less than 75 minutes.
