The Dell 7390, a member of the Latitude series, is known for its sleek design, robust performance, and extensive connectivity options. One of the features that have garnered significant attention is the inclusion of USB-C ports, which promise a future-proof, versatile, and fast way to connect devices and even charge the laptop. However, the question on many users’ minds is whether the Dell 7390 can indeed be charged via USB-C, and if so, what are the requirements and limitations of this feature. In this article, we will delve into the world of USB-C charging, exploring its capabilities, the specific case of the Dell 7390, and what users need to know to make the most out of this technology.
Understanding USB-C and Power Delivery
USB-C, also known as USB Type-C, is a 24-pin USB connector system with a reversible-plug orientation and faster speeds. One of its most significant advantages is the ability to support Power Delivery (PD), which allows for higher power levels, making it possible to charge larger devices like laptops. The USB Power Delivery specification enables the negotiation of power levels up to 100W over a USB connection, which is more than enough to charge most laptops, including the Dell 7390.
USB-C Power Delivery Standards
The USB-C Power Delivery standard has evolved over time, with different versions offering increased power delivery capabilities. The key versions include:
- USB Power Delivery 1.0, which supports up to 60W
- USB Power Delivery 2.0, supporting up to 100W
- USB Power Delivery 3.0, which further enhances power delivery capabilities
For a laptop like the Dell 7390 to be charged via USB-C, it must support one of these Power Delivery standards, and the charging source (like a wall adapter or another device) must also be capable of delivering the required power.
Requirements for Charging a Laptop via USB-C
To charge a laptop via USB-C, several conditions must be met:
– The laptop must have a USB-C port that supports Power Delivery.
– The power source (charger) must support USB Power Delivery and be capable of delivering enough power to charge the laptop.
– A USB-C cable that supports Power Delivery is required to connect the laptop to the power source.
