2. PD3.1 EPR Protocol: The Technology Behind 190W Output

Understanding the technical foundation of 190W power output is essential for merchants who want to communicate product value effectively to B2B buyers. The USB Power Delivery 3.1 (PD3.1) protocol, introduced in 2021, represents a significant leap forward in charging technology ^[2].

PD3.1 Extended Power Range (EPR) supports up to 240W maximum output at 48V and 5A, breaking through the previous 100W barrier that limited earlier PD versions ^[2]. This capability enables power banks to charge devices that previously required dedicated AC adapters, including high-performance gaming laptops, mobile workstations, and even some small appliances.

USB PD Protocol Evolution: What Each Version Delivers

Protocol Version	Year	Max Power	Voltage Options	Key Features
PD 2.0	2014	100W	5V/9V/15V/20V	First USB-C power standard
PD 3.0	2015	100W	5V/9V/15V/20V	Added PPS (Programmable Power Supply)
PD 3.1 EPR	2021	240W	5V/9V/15V/20V/28V/36V/48V	Extended Power Range, backward compatible

PD3.1 EPR introduces three new fixed voltage levels (28V, 36V, 48V) specifically designed for high-power devices ^[2]. A 190W configuration operates within this EPR framework, typically at 20V/9.5A or 28V/6.8A depending on device negotiation.

Backward compatibility is a crucial feature of PD3.1. Power banks supporting EPR can automatically negotiate down to lower power levels (SPR - Standard Power Range, up to 100W) when connected to devices that don't support EPR ^[2]. This means a 190W power bank can safely charge smartphones, tablets, and older laptops without risk of damage.

E-Marker chips are required for cables and power banks operating above 60W (3A at 20V) ^[2]. These embedded chips communicate the cable's power handling capability to the charging device, ensuring safe operation. For Southeast Asian exporters, this means that 190W configurations must include proper E-Marker authentication to meet industry standards and avoid safety liabilities.

PD3.1 EPR Maximum: 240W (48V/5A) | New Voltages: 28V, 36V, 48V | E-Marker Required: Above 60W output ^[2]
