How to Use the Mars Mini HD Projector
Setting up and using the Mars Mini HD Projector is incredibly straightforward, thanks to its plug-and-play design. Follow these steps to get started:
- Connect the Projector:
- Plug one end of the included USB-C cable into the projector’s image transfer port.
- Connect the other end to your phone, tablet, or laptop. For phones, ensure screen mirroring is enabled (e.g., “Smart View” on Samsung devices or “Screen Mirroring” on iPhones).
- If using an external power source for brighter projections, connect a 5V 3A power adapter to the projector’s power port.
- Position the Projector:
- Place the projector 0.3 to 2 meters from the projection surface (a white wall or screen works best).
- The laser autofocus will automatically adjust to deliver a sharp image. For optimal results, project in a dim or dark environment, as the 100 lumens brightness is best suited for low-light conditions.
- Start Projecting:
- Once connected, the projector mirrors your device’s screen instantly. Play videos, display presentations, or share photos directly from your device.
- Adjust the projector’s angle or distance to achieve the desired screen size (up to approximately 80 inches diagonally, depending on distance).
- Power Management:
- When powered by a phone (5V 0.9A), the projector relies on your device’s battery. For extended use, connect to an external power source (5V 3A) to avoid draining your device.
- Cooling:
- The auto-speed fan keeps the projector cool during operation. Ensure the vents are unobstructed to maintain optimal performance.
