Does a Portable Monitor Charge Like a Laptop? – Read Out!
No, portable monitors don’t charge like laptops. While some monitors use USB for both power and video, they generally require an external power source or a device like a laptop. Some models can charge laptops via USB-C Power Delivery.
In this guide, we’ll explore everything you need to know about portable monitors, from power delivery to troubleshooting common issues, helping you make the most of these versatile devices.
How Portable Monitors Receive Power
Portable monitors get power in two main ways. Most use a USB-C connection to draw power directly from your laptop, tablet, or smartphone.
Some advanced models have Power Delivery (PD), which lets them pass power through to charge connected devices.
Unlike laptops, portable monitors don’t have built-in batteries unless specifically designed for that purpose.
They can also use external adapters to operate independently, but they’re more dependent on external sources than laptops, making them ideal for low-power setups or dual-device use.
Key Differences in Power Delivery
1. Charging Capability
Portable monitors with Power Delivery (PD) can charge connected devices, like laptops or phones while operating. This is done through USB-C, which acts as a power pass-through. In contrast, non-PD monitors only draw power to run themselves and can’t charge external devices.
2. Power Source Dependence
Unlike laptops with internal batteries, portable monitors rely entirely on external power sources. This could be your laptop, a wall adapter, or a power bank, making them less self-sufficient than laptops.

3. Power Consumption
Portable monitors consume significantly less power than laptops, often under 15W. This efficiency makes them suitable for low-power devices but limits their ability to charge high-demand devices effectively.
4. Device Compatibility
The effectiveness of power delivery depends on the connected device. For example, some laptops may need more power from monitors with PD, especially if the monitor’s wattage is low. Always check device specifications for compatibility.
Laptops and Portable Monitors: A Power Comparison
- Laptop Charging: Laptops have more extensive power requirements and batteries. They draw power from dedicated adapters or battery packs.
- Portable Monitor Usage: Portable monitors are designed for low power consumption. Some rely on laptops for power through USB-C, which can drain the battery during prolonged use.
Scenarios Where Portable Monitors Provide Power
Portable monitors with Power Delivery (PD) are handy in many situations. For example, they can charge laptops during work sessions, reducing the number of cables needed.
They’re great for travel since one cable handles power and video. In office setups, they simplify desk organization while powering connected devices.
Gamers benefit, too—portable monitors can run consoles and charge controllers simultaneously. However, PD monitors work best with devices that support USB-C Power Delivery. This makes them a practical choice for those needing an efficient, multi-function display.
Devices Compatible with Portable Monitors
Portable monitors work with laptops, tablets, smartphones, gaming consoles, and even desktops. Devices need to have a compatible port, usually USB-C or HDMI.
Newer gadgets with USB-C Power Delivery or Thunderbolt are ideal for seamless connectivity. For example, MacBooks, iPads, Android tablets, and even gaming devices like the Nintendo Switch connect easily.
Just ensure your device supports video output. Some monitors can even be powered by phones or tablets for lightweight setups, making them versatile companions for work, gaming, or travel.

Built-In Battery Monitors
Some portable monitors, like the ASUS ROG Strix models, have built-in batteries. These monitors don’t need external power while running, making them perfect for portability.
Gamers and professionals love these because they work independently of laptops or wall sockets. However, they can’t charge other devices, as their battery only powers the screen.
These monitors are great for presentations or gaming sessions when you need flexibility and minimal cables.
Common Misconceptions
1. All Portable Monitors Can Charge Laptops
Not all portable monitors support charging. Only USB-C Power Delivery (PD) models can pass power to a connected device. Even with PD, they may need more power for high-performance laptops, leading to misunderstandings.
2. Portable Monitors Have Built-In Batteries
Many believe all portable monitors have batteries. Most rely on external power sources like laptops or wall adapters. Only a few models, like the ASUS ROG Strix, include built-in batteries for standalone use.
3. They Work Seamlessly With Any Device
Compatibility depends on the monitor and device specifications. Older laptops or tablets without USB-C or HDMI ports may require adapters. Also, not all devices support video output through USB-C.
4. Portable Monitors Drain Laptop Batteries
This is partially true but not universal. Monitors without an external power source will consume power from the laptop, but using an external adapter can prevent battery drain.
Portable Monitors vs. Traditional Monitors
1. Portable Monitors
Portable monitors are lightweight, compact, and designed for easy transport. They rely on external power sources and often use USB-C connections.
They’re ideal for travel, work, or gaming on the go. However, they may not offer the same performance as traditional monitors.
2. Traditional Monitors
Traditional monitors are more significant, require AC power, and are stationary. They offer better performance, higher resolutions, and more ports.
However, they lack portability and flexibility compared to portable monitors. They’re ideal for permanent workstations or gaming setups.

Choosing the Right Portable Monitor
- Power Delivery (PD) Support
- Choose a monitor with PD if you need to charge your laptop or device while using it. Monitors without PD require a separate power source, so ensure the model fits your power needs.
- Display Quality
- Look for a monitor with high resolution (at least 1080p) and good color accuracy. This ensures sharp images and vibrant visuals for work or gaming.
- Port Compatibility
- Check if the monitor supports USB-C, HDMI, or other necessary ports for your devices. USB-C is the most versatile, but make sure your laptop or tablet is compatible.
- Size and Portability
- Consider the size and weight of the monitor. A lighter, thinner model is more travel-friendly. Choose a screen size that fits your workspace and needs.
- Refresh Rate and Response Time
- If you’re gaming or doing graphics-intensive work, look for a monitor with a high refresh rate (60Hz or more) and low response time for smoother performance.
Advantages of USB-C Power Delivery in Portable Monitors
- Simplified Connectivity
- USB-C combines data transfer, video output, and power into one cable, reducing clutter and simplifying setup. This makes it easier to connect your monitor without needing multiple cords.
- Powering Devices
- With Power Delivery (PD), USB-C monitors can charge laptops, tablets, or phones. This eliminates the need for separate chargers, providing convenience during travel or on-the-go work.
- Faster Charging
- USB-C PD allows for faster power transfer compared to traditional USB ports. This means connected devices can charge more quickly while using the monitor.
Troubleshooting Power Issues with Portable Monitors
- Check Cable Quality: A high-quality USB-C cable supports Power Delivery (PD). Poor cables can cause connection and power issues.
- Confirm Power Source: Verify that the monitor is connected to a proper power source, such as an external adapter or a USB-C port with PD support.
- Device Compatibility: Ensure your device supports video output via USB-C or HDMI, as some older devices may not be compatible.
- Test with Another Device: If the monitor doesn’t power on, try connecting it to a different laptop or phone to rule out issues with the monitor itself.
- Update Drivers: Ensure your device’s USB-C drivers are current, as outdated drivers can cause power or display issues.
