When it comes to projectors, the first reaction is to hold meetings in the conference room. As a system engineer of the enterprise, I have also been exposed to some projectors. I have also been exposed to some projectors of Epson, BenQ, Sony and other brands. They are all big guys and are expensive.

Unpacking:

The package of this projector is really small. It is as big as the package of a mobile phone. The package is simple and simple. A white paper box with a logo is added There is some information on the back, that is, product model, accessories, manufacturer address, public account information, etc.

The PAPA projector is much smaller than I expected. It is only the size of an intelligent set-top box and quite portable. The silver shell of the projector is quite impressive. There are a row of scattered round hot holes on the front, which are regularly arranged into a rectangle. On the right side is the bulb lens of the projector.

On the right side of the machine is a macro adjustment knob and speaker outlet. The projection of the macro adjustment knob is very similar to the volume knob of the radio in the 1980s. The left cooling hole is not connected with the front one. A row of vertical elliptical holes are arranged in a rectangle, and the small round button at the front is the power switch button of the machine.

There are several interfaces on the back of the machine. The MicroUsb charging interface and USB interface can be connected to the U disk mobile power supply, and there is also a Mini HDMI that can be connected to the TV box, notebook and other input devices.

The projector is equipped with a simple face controller with clear functions, which is much simpler than the remote control of commercial projectors. Both the remote control and projector are silver, and the batteries are button batteries, which can make them thinner.

The configured charger is 5V2A output, which is a great good thing. It can not only be used with general mobile phone chargers, but also can be driven by a mobile power supply. It is much more convenient to use.

The bottom of the projector is covered with a black plastic cover plate, a label with barcode serial number, and four feet are equipped with long oval anti-skid silicone pads.

Startup measurement:

It takes about 15s for the projector to turn on. This projector is mainly designed to connect smart phones. Mobile phones connected to the projector can project the screen of the phone. Compatible with Android and iOS devices, the operation method is indicated on the projector.

The function used in the Android system is multi screen interaction, through which the phone can be projected onto the wall.

Although the projector is small, its lumen is not very low. The color and brightness are OK when the curtains are closed in the daytime. The image can still be seen clearly. It feels a little cold in color. If at night, the brightness should be better visually.

There is a gap between the projection to the white wall and the use of the projection screen. The brightness of the screen is slightly brighter and the color is also bright.

The projected image will change with the distance. The farther the distance is, the larger the image will be, but the brightness will also decrease. The difference between the distance of 3 meters and 5 meters can be seen from the distance between the lower frame and the black edge of the screen. The brightness is slightly brighter at 3m, which is not very obvious.

The biggest defect of this projector is that it does not have T-shaped correction function, whether manual or automatic. If you want a more positive picture, your projector must be in the right position. Otherwise, it must be biased.

The projector has a built-in battery, which can be used without external power supply, so it can be used anywhere. PaPa can be used wherever you want, but the capacity of the built-in battery is not large, which can last about an hour. A small video screen can support it after a short drive. If the power is not enough, you can use mobile power supply. The machine has built-in speakers and audio is output from the built-in speakers. External speakers are not supported. The sound is a bit low, so you can only listen to a loud voice without good sound quality.

Summary:

From a commercial point of view, the projector is placed in a room that is not large enough for the manager's office. Some commercial software promoting mobile APP is used to demonstrate to customers. For home use, it is generally a chicken ribs, without Android system, and has less resources, so it needs to be connected to a set-top box. From a personal point of view, commercial use is higher than household use.
