SigdoHoy Asus Vivobook/Vivobook Flip Round-Connector Laptop

SigdoHoy replacement laptop charger: a 65W/45W/33W external power adapter with switchable round connectors designed to work with many Asus Vivobook, Zenbook and Chromebook models (not USB-C).

When you need a reliable mains adapter for an Asus laptop that takes a barrel-style plug, this SigdoHoy unit supplies selectable 65W, 45W or 33W output and comes with four interchangeable round tips to match common Asus connector sizes. It accepts 100–240V input for worldwide use and includes one power brick plus four swappable round connectors so you can reuse it across multiple compatible machines.

Which Asus models will this charger work with?

It’s built for Asus lineups that use a round-barrel input rather than USB-C, including many Vivobook, Zenbook, Chromebook and Go series laptops. Verify your laptop’s required voltage and connector style before buying; this charger outputs 19V with three available wattage levels.

• Compatible brands and series: Asus Vivobook, Zenbook, Chromebook, Go series
• Output options: 19V at 3.42A (65W), 2.37A (45W), or 1.75A (33W)
• Connector: round barrel tips (four included, switchable)
• Not compatible with USB-C power ports

How do I choose the right wattage and connector tip?

Match the adapter output to your laptop’s power requirements: do not use a lower-wattage adapter on a device that needs more than 65W. Inspect the laptop’s charging port and your original charger plug to pick the correct round tip from the four supplied options.

• Check your laptop label or original adapter for required voltage and amperage
• Select 65W if your laptop specifies up to 65W; use 45W or 33W for lower-power models
• Compare barrel tip size visually to confirm proper physical fit
• Do not use this product if your device requires more than 65W or USB-C input

What comes in the box and what are the electrical specs?

The package includes a single SigdoHoy power adapter and four interchangeable round connectors so you can adapt the cable to several Asus port sizes. The adapter accepts universal mains voltage and provides three fixed output power levels at a stable 19V; choose the wattage that matches your laptop’s requirement.

• In the box: 1 power adapter and 4 switchable round connectors
• Input: 100–240V AC for global compatibility
• Outputs: 19V—3.42A (65W), 19V—2.37A (45W), 19V—1.75A (33W)
• Connector type: round barrel (not USB-C)

Is this charger safe and easy to use daily?

The SigdoHoy adapter is designed for everyday charging tasks with simple plug-and-play operation: attach the appropriate round tip and connect to mains power. Follow manufacturer guidelines for heat, ventilation and matching wattage to help ensure reliable performance.

• Plug-and-play: swap tips and connect to your laptop
• Universal AC input simplifies travel between regions
• Use only with laptops that accept 19V round connectors and up to 65W
• Do not use if your device requires greater than 65W or USB-C charging

Who is this for? If you own an Asus Vivobook, Zenbook, Chromebook or Go-series laptop that uses a round barrel power inlet and requires 33W, 45W or up to 65W, this SigdoHoy adapter is a practical replacement or spare. It’s also suited for households or small offices that want a single adaptable charger for multiple compatible notebooks. Verify connector shape and power needs first — this product is not suitable for USB-C power-only laptops or devices that need more than 65W.
