This is a good portable mini projector which runs on Windows 10 (most mini projectors on market use Android and are equipped with less powerful hardware). It has a pretty decent spec - 7" touch screen with 1280x800 resolution, INTEL ATOM Z8350 with 2GB DDR3L ram and 32G eMMC on board storage. It works like just a mini laptop with comes with a projector lens. The built-in projector is pretty decent as well. It utilizes 0.3" TI DMD optics technology and have native 1280x720 resolution (supporting display resolution 1080p without any problem).
I like that this projector has built-in auto focus and keystone correction. These features only come on higher-end projectors and low-end ones require manual tuning. The auto adjustment works pretty well for me as it usually does the job better than when I tried to manually adjust it. It is also very convenient as the unit will make the adjustment automatically when it senses a change in distance between the sensor and projecting area.
Screen and UI
The screen has decent viewing angle and I have no problem reading the screen from off angle. It's bright enough to be used in dark ares and dim rooms. The OS is Windows 10 so it's pretty easy to find what I want to do. The hardware is powerful enough to support a smooth GUI. Touch screen makes it easy to use and it also comes with a remote control, which works like air mouse with laser pointer.
Projector Quality
The native resolution of the project part is 1280x720 but I have no problem running HD games on it (1080P). The color is pretty vivid when the room is dark and decent when there is dim light. It's rated at 300 Lumens and I have no problem using it in a mid-to-large size room as well as outdoor with a small screen (~80"). I have also tried showing some documents using this projector. It might not be suitable for doing professional grade presentation but I think it's good enough for casual presentation purpose.
Battery Life
It has a large built-in battery rated at 46.2WH. I was able to get about 3 hours continuous gaming session using the projector as screen. I think it does a good job in battery life as the hardware is pretty powerful as a mini projector.
USAGE
I like that this projector comes with a lot of IO ports. It supports HDMI, USB, and even Miracast so pretty much all devices are covered. I can connect game consoles through HDMI ports and my Android tabelts/smartphone through Miracast.
