- Power delivery: Thunderbolt 3 can deliver up to 100 watts of power, allowing it to charge laptops, smartphones, and other devices swiftly.
How Does Thunderbolt 3 Work?
At its core, Thunderbolt 3 utilizes the USB-C connector, which has become increasingly popular due to its compact size and versatility. But what makes Thunderbolt 3 special is its enhanced capabilities, which stem from its design and technology.
The Technical Details
Thunderbolt 3 transfers data using a packet-based protocol, which is different from traditional data transfer protocols. This allows it to achieve superior transfer speeds and efficiency. Moreover, it employs a method called **alternating current (AC)** that provides power along with data transfer, making it a robust solution for modern devices.
Power Delivery (PD)
Power Delivery is a standardized protocol that forms an integral part of Thunderbolt 3. It allows devices to negotiate their power needs, making it possible to charge larger devices like laptops and even some desktops. When connected, a Thunderbolt 3 device can draw power from its source, ranging from safety limits of 5 watts (phones) up to 100 watts (laptops).
Can You Charge Your Laptop with Thunderbolt 3?
The short answer is: Yes, you can charge your laptop using Thunderbolt 3. However, several factors determine whether the charging will be successful and efficient. Let’s explore these factors in detail:
Compatibility
Charging your laptop through Thunderbolt 3 requires both the laptop and the power source to support the Thunderbolt 3 protocol with Power Delivery (PD). The most essential considerations include:
