It also supports Full HD video playback, but projects the picture at its native HD resolution.
Portability and battery life
The projector weighs 1.8 kg and can run on its built-in battery without a constant connection to mains power. That makes it suitable for carrying between rooms or using where an outlet is not immediately available.
The stated battery life of approximately 2.5 hours may be enough for a film or presentation. The conditions under which it was measured are not specified, however, so it is practical to have mains power available for longer sessions.
Resolution, brightness and picture size
The native resolution of 1280 × 720 pixels is HD. The projector also accepts Full HD 1080p video, which it scales to its native resolution for projection.
Brightness is rated at 400 ANSI lumens. A darkened room or evening viewing is therefore preferable, as ambient light can reduce the picture’s visibility and contrast.
The projected image can range from 40 to 200 inches diagonally. A range of around 80 to 120 inches is suggested for viewing. Darkening the room is especially important with a larger image. The available specifications do not state the projection distance needed for each image size.
Android and apps
The projector runs Android 9.0 and allows apps to be installed, including streaming service apps. This means content can be played without always connecting a computer or external media player.
Android 9.0 is an older version of the operating system. The availability and compatibility of specific apps and streaming services can change, so it is worth checking them before use.
Wi-Fi, Bluetooth and connections
The projector supports Wi-Fi on the 2.4 GHz and 5 GHz bands for connecting to the internet or a local network. Streaming quality also depends on the network and signal strength; support for both bands does not guarantee a stable connection.
Bluetooth 5.2 allows wireless connection to devices such as speakers. Wired connections include HDMI, USB and a 3.5 mm audio jack. HDMI can be used to connect a laptop or media player, for example.
Image correction and zoom
Automatic vertical keystone correction helps compensate for trapezoidal distortion that can occur when the projector is tilted relative to the projection surface. Four-point and 4D correction are also available for further adjustment of the image geometry. Correction does not replace a flat projection surface and may not eliminate distortion caused by an uneven one.
Zoom can be adjusted from 100% down to 50%, allowing the image to be reduced to fit the available space without moving the projector.
