- Power bank with USB-C output
- How it works: Connect the phone’s USB-C output to the laptop’s USB-C port using a USB-C cable. The power bank acts as a power source, and the laptop charges from the phone’s power.
Method 2: USB-C to USB-A Cable and Power Banks
- What you need:
- Laptop with USB-A port (older laptops)
- Phone with USB-C output (some high-end phones)
- Power bank with USB-A output
- USB-C to USB-A adapter
- How it works: Use a USB-C to USB-A adapter to connect the phone’s USB-C output to the laptop’s USB-A port. The power bank acts as a power source, and the laptop charges from the phone’s power.
Method 3: Wireless Power Transfer
- What you need:
- Laptop with wireless charging capabilities
- Phone with wireless charging capabilities
- Wireless charging pad or mat
- How it works: Place the laptop on the wireless charging pad or mat, and the phone on top of it. The phone’s wireless charging capabilities transmit power to the laptop, charging it wirelessly.
Important Considerations and Limitations
- Power Output: The power output of the phone is generally limited, making it difficult to charge larger laptops.
Typically, a phone can only provide 5-10W of power, while a laptop requires 60W or more to charge fully.** - Charging Speed: Charging a laptop with a phone is generally a slow process, taking several hours to fully charge.
- Voltage and Current: Ensure that the phone and laptop are compatible in terms of voltage and current output.
Incompatible voltage or current output can cause damage to your devices.**
