PART 1---About PAPA
Speaking of micro-investment, most friends will first think of domestically well-known brands such as Kami, Nuts, and Cool Music. It is certainly not very familiar to PAPA. Therefore, I think it is necessary to first introduce the PAPA brand.
The following content is taken from PAPA official website
“Beijing Xiaoxiang Fast Running Technology Co., Ltd. was established in November 2014. It is an innovative technology company focused on smart projection and peripheral entertainment hardware. In January 2015, PaPa Entertainment was awarded RMB 5 million angel investment by the public. For former Alibaba and Tencent executives, as well as Northern Lights Ventures, in July 2015, PaPa Entertainment completed a Series A financing of 45 million yuan.
"Building smart entertainment terminals for young people" is the vision of PaPa Entertainment. PaPa Entertainment hopes that our products will become your life entertainment center, bring more colorful colors to your life, and explore endless possibilities through our efforts.
In 2015, PaPa Entertainment released the first product, PaPa pocket cinema, on Taobaozhong.

PaPa mobile projection as the second product launched after the pocket theater, will bring what kind of experience, the following is announced for you.
PART 2---- Unpacking
The whole body of the box is white, and the dark red stamping LOGO is adorned in the middle.
On the back of the box is printed a list of parts, social platform entrance, official website information and other information
Traditional world cover packaging, after opening accessories at a glance
A family portrait
The power supply adopts the more common 5V2A specification
The first impression of getting a projector is compact. The overall size is 212.5px X 212.5px X 40px.
The shell is made of magnesium alloy material, it is very high grade, and the texture is very delicate
The back of the plastic backplane, note that there is no tripod screw, which means that this projector will not be able to use the traditional tripod
For ease of use, it is highly recommended to use with suction cup brackets
All the interfaces of the machine are distributed on the back, including MicroUSB, USB2.0, infrared receiver, Mini HDMI interface.
The front of the fuselage is a projection lens and cooling holes
The power button is on the left side of the machine. In order to dissipate heat, in addition to the front and the outside, a row of cooling holes is also designed.
The right side of the fuselage is focus knob and sound hole
Although the remote control and the host magnesium aluminum alloy are relatively similar in color, they are plastic materials and only cover the surface with a layer of imitation metal coating.
The remote control is very simple, even the home button on the remote control of ordinary smart devices (such as boxes, smart TVs), menu keys are not, why after the article will be announced for you
The back cover of the battery is opened by rotation. The built-in button is the C2025 button battery. In addition, it is necessary to pay attention to the way that the remote control adopts the infrared mode. The infrared directionality is not as convenient as the use of Bluetooth.
PaPa mobile phone projection only weighs 134g, actually lighter than the current mainstream large-screen smart phones
With the remote control and charger, the travel weight is only 224g, and the portability is quite outstanding.

PART 3----Function introduction
The main interface after booting, you can see PaPa mobile phone projection is not like the usual micro-projection built-in open operating system, but like positioning in the mobile phone projection, support for Android devices, Apple devices and PC with the same screen shot, in addition Provide external U disk player
1. Local play
Provides 4 functions for movies, pictures, music, and text
Click to enter this drive letter UI interface appears personally feel a bit redundant, PaPa phone projection no TF card slot, so only an external U disk, there may be only one drive letter is completely unnecessary to choose, not as direct Display U disk content is more direct
PaPa mobile phone projection does not automatically recognize video, music, pictures, etc., enter the "movie", "picture", "music" "text" options need to manually specify the file directory to play
The built-in player playback video interface is as above and provides basic video control options, but fast forward and rewind can not be realized by quickly shifting the time axis through the left and right buttons on the remote control. Only 4x can be selected by the fast forward and rewind buttons in the player. , 8x, 16x speed to achieve, slightly inconvenient. The video playback part tested the common AVI, MP4, RMVB, MKV format 1080P videos, all of which can play smoothly. Cannot play when trying to play 4K resolution video.
Music player interface
In addition, the picture browsing part tried the more common jpg, bmp, gif format pictures, in which jpg, bmp can browse normally, and gif format can not be identified. The text part of the txt file can be read normally, and the word file cannot be identified.
2. Android with the screen
Android uses the Miracast protocol in the same screen mode, which is suitable for most Android phones supporting this protocol. There are slight differences in connection steps for different brands of mobile phones.
Mobile phones that participate in Android test with the screen ---- OPPOFIND7, Meizu MX5, Huawei MATE7
OPPO mobile phone screen connection steps
Meizu mobile phone with screen connection steps
Huawei mobile phone with screen connection steps
Synchronize the phone desktop after establishing a connection

3. IOS with the screen
IOS adopts Airplay protocol with the screen, suitable for Apple devices
The device that participates in IOS screen test is Macbook, iPAD mini2
iPAD easily selects the PaPa projector with AirPlay
Macbook same screen connection method and iPAD, same screen display function is completely normal
4.Windows with the screen
In addition to Android, IOS screen, PaPa projector also supports Windows wireless projection. In order to fully test the degree of support for the windows platform, three different platforms of windows devices are specifically selected here. Notebook HP 8570W----Windows 10 pro, Tablet Surface2----WindowsRT 8.1, Mobile Phone LUMIA 950XL----Windows Mobile 10
After the laptop HP 8570W clicks on the connection to the wireless monitor, it successfully searches for the PaPa projector, but when it is connected, it always shows that it cannot connect, and it ends up failing.
LUMIA950XL found successful connection is not a simple projection with the screen, actually CONTINUUM wireless display, momentary tall
Mobile phone seconds change "mobile PC", by sliding the phone screen can control the mouse pointer movement
Viewing email on a large screen is much more comfortable than on a mobile phone
Surface2 connection as above
Try to set the extended display mode in wireless projection mode, normal display
Through the test of the above three devices, personally feel that the compatibility of PaPa and the screen is not particularly good for the windows platform. First of all, the notebook HP8570W (Broadcom network card) can search for the projector but can not connect, although surface2 can normally project with the screen, but it will Randomly interrupted and cannot be connected again (you can only delete projections and add them again). The perfect support for Lumia 950XL is a highlight
5. Wired projection
Trying a Macbook, Windows computers connected to a PaPa projector via HDMI to MiniHDMI are the same as an external display. It should be noted that in the wired projection mode, the resolution of the PaPa projector must be set to 1280x720, otherwise invalidsignal will be displayed and the image cannot be output.
6. WIFI hotspot
PaPa projector can use projector as wifi hotspot in apple mode
PaPa-EDC can be searched via mobile phone wifi in Apple mode
After successful connection, visit http://192.168.49.1 in the browser to reach the wifi management interface of PaPa mobile phone projection
Click on the Internet to see the list of currently saved wifi
Click to scan to add wifi network, PaPa projector supports 802.11AC mode, speed can be guaranteed. However, the measured signal is not very good. Only two home wireless signals can be searched in the room, and a bunch of signals can be searched by mobile phones and laptops in the same place. . .
In the settings interface can also set the language and wifi password
Personally feel that the wifi hotspot provided by the PaPa is a natural function. Imagine the use of the wifi hotspot. 1. When you go out, you can use the SIM card to provide wireless network for your mobile phone, tablet and other devices. The PaPa mobile phone does not support the SIM card. 2. In the case of a wired network, the wired network is converted to a wireless network through a wifi hotspot to provide network services for portable devices. The PaPa mobile projector does not support wired networks. 3, as a wireless repeater, to enhance the signal coverage, and PaPa phone projection wifi signal strength worse than the phone, tablet, notebook worse than a grade, so as a relay router is also unqualified
7. Mobile power
PaPa mobile phone projection built-in 1900mAh battery, when in the outdoors can be used as a mobile power emergency to charge the phone, although the power of 1900Ah is slightly paralyzed, but the occasional emergency is still good
PART 4----Projection effect
1 Projection size
1.5 meters projection size is about 50 inches
At a distance of 2 meters, the projection size is about 65 inches.
Projection size is approximately 100 inches at a distance of 3 meters
2. Sharpness
Projection distance of 2 meters (about 65 inches), for more text, more intensive web display personally feel less tolerated, PaPa projection is relatively low resolution of the drawbacks undoubtedly exposed
At the same distance, the display effect is still acceptable for the relatively large application environment of PPT.
Although the jagged edge of the font is very obvious from a close observation, it does not cause much impact on individuals who watch the PPT 2 meters away.
Projection distance is 3 meters (about 100 inches), viewing distance is about 4 meters, at this distance to watch the movie clarity is acceptable, but the display effect of PPT at this distance has been greatly reduced
3. Brightness
Turn off the light at night, the brightness of the PaPa phone projection is still good
Pulling blinds (not blinds) during the daytime, the disadvantages of the lack of brightness of the miniature projections begin to appear, and static images such as viewing pictures are barely acceptable, but the dynamic picture of the movie has become ineffective.
In the daytime, the effect of the display without pulling the curtain could not be tolerated. . .
4. Color
Original image
PaPa mobile phone projection, through the comparison can be seen PaPa mobile phone projection color saturation is higher than the original map, the color looks too strong, and the original difference is larger
PART 5----Life time
The battery life of the external USB 1080P video file and the same screen projection mobile video were tested respectively. The results are as follows:
External USB: 65 minutes
Same screen mobile phone: 1 hour 25 minutes
Not surprisingly, the 1900mAh battery is really a short board. I am very dissatisfied with this battery life. Although I have to compromise on the battery capacity in order to be ultra-portable, I think it can be a portable projection to play a full movie. The bottom line
PART 6----Temperature
At room temperature around 20 degrees, the mobile phone plays video with the screen for 1 hour, the temperature gun displays PaPa mobile phone surface temperature of 29.8 degrees, the temperature control is very good
PART 7----Summary
Let's talk about the advantages first:
1. The appearance of aluminum alloy shell is very good
2. Small size and ultra-portable
3. Wireless with screen Android, Apple, Windows platform support (but the Windows platform wireless display compatibility needs to be improved)
4. Can be used as a mobile power emergency
Disadvantages:
1. As a projector, projection quality is the most important aspect, and PaPa mobile projection needs to be improved in terms of resolution, brightness and saturation
2. Short battery life, the main mobile is portable, poor battery life leads to loss of portability with the power supply
3. Product positioning is too "single", too stressed the concept of "same screen", operating system closure only provides the same screen function, and can not install other video playback software, want to watch the movie must be output through other digital devices with the screen It will be more convenient to play the video software in the projector directly at home or in the case of a wifi network.
4. The general effect of putting away, do not have too high expectations for this size of portable projection
