Using a USB-C Power Bank with Your Projector

Connecting your portable projector to a power bank allows you to enjoy entertainment in remote locations without a power outlet. However, to ensure this setup works seamlessly, you need to consider the following:

Ensure that your projector, USB-C cable, and power bank meet the specified requirements to guarantee successful charging for your projector.

●Step 1: Ensure You Have the Right USB-C Cable

Make sure you have a USB-C cable that supports the Power Delivery feature for USB-C. A USB-C cable that doesn’t support PD will prevent your power bank from properly charging your projector.

●Step 2: Check Your Projector's Specs

Before you start looking for a power bank, examine your projector's specifications. Specifically, focus on its Power Delivery Input (PD In) and Compatible Power Delivery (PD Capacity) requirements.

●Step 3: Check the Power Bank's Specs

Next, verify the specifications of your potential power bank. Ensure that its USB-C Output values meet the requirements specified for your projector. This alignment will guarantee successful charging without any hiccups.

Tips: Where and what should I look for on my projector and power bank’s specs?

Carefully review the specifications of your projector and power bank when making a purchase to ensure they meet each other's requirements.

Projector Specifications: Examine your projector's user manual or visit the manufacturer's website to find information related to Power Delivery Input (PD In), USB-C compatibility, and DisplayPort Alt Mode support. Verification of voltage, current, and wattage is required.

How to Calculate the Projector's Supported Wattage? Use the following calculation equation:

V: Voltage

A: Amperage

V x A = Wattage

Take the BenQ GP100 portable projector as an example; in this case, the Power Delivery Input ranges from 20V-2.25A to 5A. So:

20V×2.25A=45W (Minimum Power Delivery)

20V×5A=100W (Maximum Power Delivery)

Hence, the Power Delivery support ranges from 45W to 100W.

Power Bank Specifications: Check your power bank's user manual for details on USB-C Output values and Power Delivery support. You can also refer to the manufacturer's website to access comprehensive specifications regarding its USB-C features.

Using a Nintendo Switch with your Projector

If you plan to use your projector for Nintendo Switch gaming, you can simultaneously charge your device via the USB-C connection. To do this, follow these guidelines:

Ensure that your projector and USB-C cable align with the specified requirements to guarantee successful charging for your Nintendo Switch.

●Step 1: Ensure You Have the Right USB-C Cable

Make sure you have a USB-C cable that supports both Power Delivery (PD) and DisplayPort Alt Mode. This dual support is essential for projecting the Switch's gameplay and charging it at the same time.

●Step 2: Check Your Projector's USB-C Port

To ensure your projector can project the Switch's screen while charging it, confirm that it has a USB-C port with DisplayPort Alt Mode and supports Power Delivery with an output of at least 15V and 1.2A (18W). If your projector doesn't meet these criteria, you may need to connect its DC-In power port directly to a power outlet via its power adapter and cable.

Using Your Mobile Devices with Your Projector

Your portable projector can also project your mobile device's screen while keeping it charged. This is perfect for uninterrupted entertainment. Follow these steps to ensure it works seamlessly:

Verify that your projector, USB-C cable, and mobile device meet the mentioned specifications to ensure successful charging and screen casting for your mobile device.

●Step 1: Ensure You Have the Right USB-C Cable

Make sure you have a USB-C cable that supports both the Power Delivery (PD) and DisplayPort Alt Mode features for USB-C. A USB-C cable that doesn’t support both will prevent your projector from projecting the device’s screen and charging it at the same time.

●Step 2: Check Your Projector's USB-C Port

Verify that your projector's USB-C port supports DisplayPort Alt Mode and Power Delivery with an output of at least 18W. This is crucial for broadcasting your mobile device's screen while charging it. If your projector doesn't meet these requirements, consider connecting its DC-In power port directly to a power outlet.

●Step 3: Check Your Mobile Device Compatibility

Depending on your device, you need to check for compatibility:

For Android Devices:

Ensure your Android phone or tablet supports Power Delivery and features DisplayPort Alt Mode capabilities. You can check for DisplayPort functionality using the "Type-C Video Checker" app from Google Play.

For iPhone:

iPhones from iPhone 8 onwards support Power Delivery, while only models from iPhone 15 onwards support both Power Delivery and DisplayPort Alt Mode. To connect your iPhone (excluding iPhone 15), you'll need a USB-C to Lightning cable for power delivery only.

In Conclusion

To make the most of your portable projector's USB-C port, you need the right USB-C cable and must consider your specific usage scenario. This means checking the specifications of your projector, cable, and device. By doing so, you can harness all the features and capabilities that the USB-C interface has to offer, ensuring an outstanding viewing experience.
