For still images and presentation slides, the total run time comes closer to two hours on a single charge.īecause the SPro doesn't charge through micro USB like a standard phone, you'll need to be near a wall charger if your sales pitch runs long. Although the battery size seems robust considering most high-end Android phones come with a capacity under 3,000mAh, I only get about an hour and a half of video playback. The SPro is powered by a 5,000mAh battery. Speakers can connect to the SPro wirelessly with Bluetooth or via the audio-out jack. To overcome fan noise when playing movies, I connected a Bluetooth Jambox Mini. Connect the USB cable to the projector’s and laptop’s HDMI ports. ![]() The fan kicks in immediately when the projector is turned on. The downside, however, is that the fan on the SPro spins louder than the audio output and overpowers the speaker. The built-in speaker delivers decent audio quality that's surprisingly loud. ![]() Copyright-protected movies purchased through iTunes would not play on the projector through the HDMI connection. Using an iPhone with a Digital AV adapter, I was able to display some content - like photos and presentations - but not others. I was able to connect my Windows laptop and an Android tablet to the projector using both a wired HDMI cable and wirelessly with Miracast. You'll definitely want to turn the lights down - if not completely out - before you begin your "feature presentation."Īdditionally, with the HDMI port, I can also connect a smartphone, laptop, or tablet to project content from those devices. The brightness is less of an issue for smaller projections, but when I projected a 10-foot presentation, it was harder to see the image unless the ambient lighting was dimmed low. ![]() Though its image quality may suffice in a pinch, I found the SPro's relatively meager 100 lumens of brightness output makes it harder to use in a room that is not dimmed. This makes it ideal for showing off HD video, which are captured in 16:9, or for displaying photographs, which are often shot in 4:3. Images are displayed in 4:3 or 16:9 aspect ratio. ![]() The SPro can project images to a display size of between 10 inches to 10 feet (254mm to 3m). To reconnect, press the OSD button on the monitor, select Menu, select Input, and then select a DisplayPort setting.
