With the maturity and popularization of LED technology, LED micro investment has become more popular with longer service life, more convenient carrying and more affordable price. In particular, the intelligent micro investment with Android platform has further solved the problem of source selection and ease of use. It has become another choice among people's needs for large screen viewing. In recent years, new products of intelligent micro investment have continued. As the nut of the industry's new star, the G1 launched last year, which combines avant-garde fashion style with a full range of audio-visual entertainment experience, is quite impressive. Recently, she has also brought another masterpiece of portability, P1, which aims to create "smart mobile cinema" for users. How does P1 perform? Let's take a look:

In order to match the size and length of P1, its packaging box adopts a long black gift box design, and there is no redundant promotional logo in the whole package, which is quite low-key and introverted. In addition, a pair of 3D glasses is also provided as standard, which is delivered randomly in the form of independent small package.

The back of the box body is only affixed with a label printed with the model, factory address, official number QR code and Yizhong certification (3C, CE, FC). It can be seen that its "manufacturer" is Huole Technology.

Exclusive charger with huge size, large size, sufficient weight and good workmanship. It's just too big to carry out. The line length is about 2 meters by visual inspection, which can be used in various scenarios. Look while filling, don't worry about the short line.

Great wall， Its charging specification is 14V 4.2A. The charging head adopts the double head concealed type, which can be hidden in the card position when not in use.

In addition to the host, Nuts also equipped a pair of DLP-Link 3D shutter glasses for P1 in order to provide P1 with audio-visual viewing in 3D mode. The glasses need to be charged. The USB port is located in the middle of the top of the frame. It can work for 40 hours after being charged once. However, in actual use, it should be noted that the glasses must be located at the rear end of the P1 projector facing the position (receiving signal), and it is better not to have other equipment interfere. (The above figure shows the specifications and parameters of glasses)

USB charging cable, wiping cloth and use guide provided with the mirror.

On the signal receiving window and power switch at one side of the mirror leg, press briefly to start the machine, and long press for 3 seconds to turn off the machine.

The first time I knew nuts, I started with G1. Although I didn't play with nuts, I was still amazed by the body design of its UFOs. The appearance of P1 this time is also unique, and the "thermal cup" shape of the cylinder is expected before the real machine. However, although the machine body is solid enough and the materials used are thick enough, its size (245 * 73mm) is larger than the expected "three circumference" size (245 * 73mm) compared with the ordinary "insulation cup". As for the second generation product with "P" as its main feature, P1 is undoubtedly less portable, and without mentioning the "huge" power adapter, P1 can only be stored in the backpack. However, as far as the appearance design and details of the whole machine are concerned, the author is very satisfied.

If you use three words to describe P1, they are "calm", "thick" and "delicate". The brown body is treated with black panels, buttons and black metal shiny borders, which makes it calm and grand. The weight of 1.02 kg is also heavy in the hand. In addition to solid workmanship and materials, it feels heavy. The details of the whole machine are carefully handled. There are no burrs, corners or superfluous words. The simple LOGO of the brushed metal panel shows a sense of refinement. Of course, in order to meet the individual needs of different user groups, P1 also has a variety of colors to choose from, and is named after the founder and the three Star VCs respectively, which is quite interesting.

All P1 buttons are listed on the top of the fuselage, including power supply, volume adjustment, one button 3D and "nut" keys, "three king kong" keys (return, home page and menu, I believe those playing Android will not be unfamiliar), four-dimensional direction and confirmation keys. The keys are made of black glue, which feels good. If this is troublesome, you can also use the infrared remote control (not standard) or the "nut control" on the mobile phone.

Short press for about 5 seconds to turn on or turn off the device. Press the power and 3D keys at the same time to force a restart. Personally, it is troublesome to turn off the device settings. When you turn off, you also need to select the confirmation shutdown option through a dialog box. These extra steps can be completely omitted and unnecessary. In addition, this key also acts as a status indicator. If the orange light is on for a long time, it means charging is in progress (in actual experience, it will only be on for a while during charging), and if the white light is on for a long time, it means charging is complete. In case of abnormality, the orange and white lights will flash alternately.

The metal brushed panel on the front of the fuselage is engraved with the English LOGO of "JMGO".

The LED lens is located on the left side of the front of the fuselage, and the focusing knob is located on the left side. The surface material is made of metal, but unfortunately there is no dust-proof push cover, so it is easy to be contaminated with dust after a long time. The position of the focusing button is not well handled, and it is easy to block the lens and cause shaking when focusing.

In addition, on the right side of the lens are air inlets and infrared windows. P1 adopts the design of air outlet after moving forward, and the infrared window is very "sensitive". In addition, P1 does not have a hard shutdown button, so it happens that when some infrared remote controllers are remote controlled by one side, it is very easy to "start up".

This lens of P1 adopts mainstream DLP-3D display technology. Its brightness is 250 ANSI lumens, output resolution is 1280 * 720, zoom ratio is 1.47:1, and the projection size is 40-180 inches. It can project 40 inches at 1-1.2 meters, 150 inches at 3.9-4.5 meters, and so on. The maximum projection size is 300 inches at the farthest distance of 7.8-7 meters. According to personal measurement, the effect is best at about 100 inches. It can be seen at any size, However, the graininess is more obvious.

The back of the machine body is equipped with an air outlet and a set of interfaces. In addition to the absence of TF card slot, P1 has a wide range of interfaces, including standard USB ports, Micro USB ports, and HDMI ports. It can be connected to a USB flash disk, mobile hard disk to play content, or TV, box, flat panel, etc. to fill the screen and extend. In addition, P1 uses DC pinhole charging. When it starts up and runs, the "noise" caused by its fan is quite large. In the official version of the system, it seems that the gear can be selected (9 by default, and the noise can be ignored after changing to 2), but the author cannot change the version of the test machine.

The speakers of P1 are distributed on both sides of the body. If viewed from the side, P1 is like a small desktop audio, and its sound performance is as excellent as G1.

The fuselage is equipped with a 15600mA battery. Officially, the battery life is 5 hours, but in fact, it is about 3 hours (including WIFI, the brightness is 1). In other words, it is basically like 5 domestic dramas (automatically skips the beginning and end of the film) or two domestic movies (generally about one and a half hours for feature films). Of course, this machine also supports charging while launching, There is no need to consider these at home.

P1 has a ring of rubber anti slip pad at the bottom of the fuselage, and a screw hole is left in the middle for the tripod access and fixation. However, since P1 is relatively heavy, you have to choose a larger and stronger one. In addition, various information is printed on both sides.

In terms of hardware, NutP1 adopts the MSD6A628VX scheme of Morningstar Semiconductor (MStar). Although there is a gap compared with the current flagship performance, it is enough for P1, which focuses on audio and video. According to the actual measurement, after the author installed a large number of APPs, the switching did not get stuck. Here are some brief introductions about this scheme found by the author:

CORTEX A7 core, 1.5GHZ main frequency, based on Android CPU quad core GPU The four core 4.4 operating system supports APP expansion, can connect wired and wireless networks to browse web pages and play online videos. The built-in wifi three-way USB interface supports external mobile hard disk to play video and operation files, and supports keyboard, mouse and wireless remote control operations. Its GPU is mali-450MP2, with 1GB of memory, built-in 4G INAND storage space, and supports HEVC/H2.65 video decoding and H.265 video playback, USB2.0 and USB3.0 interfaces can be connected to large capacity mobile hard disk, and can also be connected to mouse and keyboard for operation. Compared with MStar6A928, it is inferior in specification and overall computing speed, but it is enough for entertainment 720P.

Nuts define P1 as "intelligent mobile cinema", and its main selling points are intelligent independence and on-demand delivery. Nowadays, intelligent micro investment uses Adroid customization system. P1 is no exception. In order to adapt to the situation of horizontal screen projection, P1's Android customization system uses the Metro UI style similar to WIN8. Function cards of different colors are equipped with large fonts, which are more intuitive and easy to use than native ones. The whole interface has six main functions, namely, Love, Recommendation, Channel, Application, My and Settings.

On the issue of film source, many manufacturers have chosen to cooperate with third-party content providers, while Nuts has chosen Litchi TV (launched by Yangguang Galaxy, one of the seven OTT licensees, backed by iQiyi, PPS and other video providers). There are a wide range of film and television resources, covering the latest variety shows, animation, film and television dramas and exclusive programs. It is a smart TV large screen video application customized for TV. Among them, "Love to watch" is a bit like content aggregation. You can learn the latest information, sports, food and other information by selecting various customized channels. The picture is fresh and timely, and the content is short and exquisite. In addition, there is a power display at the upper left corner, but it does not support digital display. In addition, my P1 is a testing machine, so the power is always displayed at 100%. I believe that the official version will be corrected.

The "Channel" page is a collection of six frequently selected channels. Of course, you can also further select other channels you want to watch later. The classification of sub options is more user-friendly, and supports skipping the title/tail, clarity selection, etc. What is rare is that it also supports the popular "offline cache".

As Android, how can we not support application expansion. In "Application", common applications are listed in a grid, and you can further view the application list. The "Apps" page is composed of two parts. On the left side are "App Store", "Media Center" and "Game Center" (in cooperation with a third party, it is necessary to install an app with a handle). On the right side are the recently installed apps arranged in a grid. On the lower right corner, you can view more (all apps). It is worth mentioning that, for some reasons, There are no AV apps in the built-in app store, but there are many other entertainment and commonly used apps. We can install the "Dangbei Market" and other third-party markets to obtain the desired AV APP.

Basic items such as wireless, weather, sound and display can be set in the settings. At the same time, you can press the "nut" button at any time to quickly set. It lists common options such as signal source (for switching to HDMI external screen), 3D mode and playback ratio, which is quite practical. Finally, there are two ways to upgrade the P1 system: local (firmware package installation) and OTA. However, it is not possible to connect the server for online upgrade.

The recent hot "Langya List" is updated in a timely manner. You can preview it first and then play it in full screen:

In terms of resource search, full keyboard and T9 keyboard are used. Although it is not as convenient as PC query, the support of keyword association query has greatly improved the speed of film search.

It can be seen from the playback picture that the whole is cooler (the measured pictures will be put at the end of the article), and the details are very clear. Due to the low lumens, it is still difficult to watch in the daytime, but it will be very comfortable if you close the curtains or watch at night (suggested brightness of 1, 2 is somewhat dazzling). In addition, P1 also supports rear projection flipping.

There are few 3D movie sources, and the display effect is not ideal. The next 3D broadcast, the effect is good:

In the media center, you can directly view the contents of USB external USB flash drive and mobile hard disk. Only pictures, songs and videos can be played directly. The decoding ability of P1 is quite good.

There is no pressure to play locally, and there is basically no format that cannot be played:

You can also connect HDMI, synchronously project tablet or notebook, conduct PPT display, or play games.

Finally, let's take a look at the color. P1 is cooler. It can be seen from the figure that the deepest part of the blue sky is black and purple.

However, for the restoration of details, P1 is really good, clear and delicate.

The performance under the black background is very good.

Everyone has different preferences for cold and warm colors, so different opinions can only be expressed on the effect, but the author likes this kind of cold color.

Conclusion: As the second smart LED micro investment of Nuts, P1's comprehensive performance is very good. The solid workmanship, exquisite design and clear and exquisite picture effect are impressive. Although there are some minor flaws in the details of the experience, the official version should be improved and corrected because what I have got is a test machine. However, in terms of its positioning as a "mobile cinema", its rather large and heavy body makes its "mobile portability" somewhat discounted. In general, if you like watching movies in the evening and chasing new people like the author. Usually, P1 is a good choice for playing games on a large screen, or for simple PPT display, with built-in Android platform and numerous audio and video resources.
