To achieve charging speeds above 100W, your laptop, power adapter, and USB-C cable must all support the USB PD 3.1 Extended Power Range (EPR) standard. If any component in this chain is limited to the older PD 3.0 standard, or if your laptop requires a proprietary manufacturer handshake, you may see reduced charging rates or a "Slow Charger" warning.

How Power Delivery Standards and Proprietary Protocols Affect Charging

Achieving high-wattage charging requires the laptop, charger, and USB-C to all support the PD 3.1 EPR standard. Even with these met, the USBC-10IN1E reserves approximately 15W for its own function, passing approximately 125W to the host. Furthermore, some laptop brands use a proprietary communication signal found only in their original power bricks for >100W charging; without this signal, the laptop may be limited to 100W, and trigger a "Slow Charger" alert in the BIOS or OS.

How to Optimize Charging and Manage System Alerts

To maximize charging performance, ensure you are using a USB-C cable rated for 140W or more between your 140W power brick and the hub's PD-In port. If you see a "Slow Charger" warning on a system that may use proprietary protocols for >100W charging (such as a Dell or HP system), you can typically dismiss these warnings within the BIOS/UEFI. The laptop will often still charge effectively, albeit at a slightly lower rate than the original proprietary charger.
