As far as projectors are concerned, they may be familiar to everyone. The first thing should be the high-tech products that teachers used to teach at school. For many years, the positioning of projectors is that they are expensive, troublesome to operate, cumbersome to connect, useful for teaching, short in life, and poor in projection display. So many shortcomings or deficiencies exist, So it has been an office product for years. With the development of the times and the rapid progress of electronic products, more and more "antiques" have been added with the word "intelligent". So today, let's see if this nut P1 projector can break through the traditional impression? Let's have a look.

Unpacking&Play

Simple paper shell packaging, with Lei Feng's trial logo on the front, simple and clean.

This is the case after taking it out. Two thick foam sponge pads wrap the host box, and the small box below is 3D glasses. The glasses are also well protected by independent packaging.

After opening it, I saw the mainframe. It was simple and refreshing. It abandoned the big and ugly image of the projector in the past. The front was very simple. The first feeling was how the engineers did it. The components that used to be so large were integrated in such a small place. From left to right, the front was the focus rotation button, and the middle was The lens has green reflection, indicating that there is coating, which is helpful to restore the authenticity of projection color The right side is the air inlet, and the right side of the air outlet has an infrared window for receiving remote control signals. The small box on the right side of the host is the power adapter.

The first feeling of getting started is that it is small, simple and beautiful. Although I have seen the official website parameters and pictures, I still feel very refined when I get it. The brand logo is also very simple and clean. It is well integrated into the whole, without any unexpected feeling.

At the first sight, the nut P1 has a bright feeling. The exquisite industrial design makes P1 interpret the breath of fashion and trend. The overall round cylinder shape does not even make people think it is a projector, but at first glance it may be regarded as a water cup. The main color of the surface is black and dark coffee, and the matte design is adopted. The fashionable and beautiful appearance shows a calm and restrained temperament. The whole machine can be held in one hand and won't take up too much space when placed in the backpack. This is also the meaning of mobile cinema.

The overall body adopts a large number of sleek design styles. The large area of metal material makes the holding feeling of one hand very good. In addition, the damping of the button is moderate, which makes people feel that this is not like a projector, but an intelligent device.

The power adapter is not so small and delicate. It is about the same size as a portable router. The power output is made of 14V4.2A Great Wall. The plug can be folded for easy storage. The line is about 2 meters long.

The nut P1 has built-in speakers at both ends, aluminum alloy gold ring buckles, metal Zhongnet and the whole machine. The biggest advantage of the built-in speaker is that it doesn't need to be connected to external speakers. The sound quality of the nut has also been adjusted by the master. Generally, there is enough audio and video. Of course, in order to achieve the best theater effect, the small editor has purchased an additional set of speakers, The main enhanced bass effect is quite shocking. Of course, compared with the ordinary projector, the nut's built-in speaker is absolutely of the explosion level. The symmetrical long drum structure also makes it have a better sound production effect. The 2 × 4W small cavity speaker is small but powerful. The sound intensity is up to 80db, and the medium and low frequency timbers are analyzed in detail.

The interfaces are arranged on the back of the machine, including HD interfaces, USB 3.0, AV audio and video, and MICRO USB interfaces.

Since the light-emitting unit is an LED light source, it generates a large amount of heat. The heat is absorbed by the internal pure copper heat sink and carried out by the adjustable 10 stage fan. The grid on the left is the air outlet for heat dissipation.

The main parameters of P1 are as follows:

Brightness: 250ANSI lumens

Contrast: 1000:1

Standard resolution: 1280 × 720

Color gamut: ≥ 120% NTSC

Projection size: 40 – 180 inches

CPU： Quad core MStar-6A628VX

GPU：Mali-450MP2

Memory: 1GB DDR3

Battery capacity: 15600mAh

Others: support 3D, H.265 hard decoding, and dual band Wi Fi

250 lumens is enough, which can be used for 30000 hours. The actual use effect of 1280 * 720 resolution is also enough. If the maximum resolution is 4k, it is unrealistic at the price of more than 2000. However, the actual display effect is many times better than the office projector I have seen. The wide color gamut and large size projection are compared with the 40 inch and 50 inch TV sets, My little friends were shocked when it was first played. The only problem may be that the CPU GPU is enough. The super large battery capacity can last for 5 hours, and other kinds of decoded movie files are also under no pressure.

The bottom is also equipped with screw holes, which can be easily installed on the ceiling of the support. The universal size can also be installed on the tripod or mobile phone support. After all, it is not easy to project on the wall when it is flat. It is also equipped with anti slip mat, which is convenient to maintain stability.

3D glasses were also included randomly, and the actual experience effect was quite satisfactory.

Display&Software

In terms of software, the overall UI setting is relatively simple. It is basically similar to other Android TV boxes, and it is easy to get started. Too many information movies, TV dramas, variety games, etc. will still drive people crazy. On the left side, LeEco's rotating desktop is similar to that of iQiyi. Of course, if you can customize the content, it would be better. Although only 1GB of memory is available, after five or six apps are installed, The system can still maintain smooth operability for the time being, and has humanized built-in automatic memory cleaning. The design of the system is good, but there is no response after the first boot. Common input problems still make people uncomfortable. For example, my WiFi password can be set with alphanumeric characters, which is quite complicated to press. Sometimes the keys will not be triggered because they are not pressed in place. The power display also remains at 100% all the time, and the online upgrade display of the system is up to date. It is expected that it will be improved later.

The display effect is also relatively satisfactory. There is no pressure to decode all kinds of video files on the USB flash drive and office documents. Playing 1080P video can also feel the same effect as the TV. There is no pile of parameters here. From the perspective of Xiaobai, the display effect of home theater is sufficient.

In terms of content, it is not too much to say that mobile theaters can provide tens of thousands of video screens and other content through partners, including popular dramas, movies, variety shows, education, children's programs, etc. If you really can't meet your needs, you can also install third-party software, such as Android software such as VST Taijie Youku, which are universal, and it is also good to watch TV programs.

Since no physical remote controller has been officially adapted, a mobile APP remote controller has been launched. I don't know whether it is due to cost or environmental protection. The only drawback is that it only supports Android clients, while Apple does not.

The remote control provides the up, down, left, right navigation confirmation key in the middle, the power off key and 3D function key on the top, and the home page, menu and return volume adjustment on the bottom. In addition, the volume can be adjusted by pulling down the interface. Of course, the volume of the projector can be adjusted directly through the volume adjustment button of the mobile phone. Because of the WiFi connection, Therefore, after installation, it is necessary to maintain the same WiFi signal with the projector before it can be identified and connected. It should be noted that if one is at 2.4G and the other is at 5G, it cannot be identified.

The remote control experience of the mobile phone is not very perfect. The connection time is long, and there have been several failures in the process. The feedback is timely under normal connection, and occasionally it will be delayed or stuck. We look forward to updating this later.

advantage:

1 It is a very cost-effective home theater center, which can directly project the white wall.

This is an extremely portable home theater, giant screen TV, game console, etc

3 Super long endurance for 5 hours, allowing you to enjoy entertainment even when you are away

4 Excellent speaker and exquisite sound quality

5. Simplify. You don't need to connect any laptop. A USB flash drive is enough to make it your mobile office center

6 Ultra clear picture quality makes people think that this is not a projector and can better protect your eyes

Insufficient:

1. The hardware configuration has room for improvement. The software system needs to be improved

2. Due to the low power, the bright light projection effect is poor

3 APP remote control experience and body button operation are general
