Portable mini projectors – features of choice, the best models of 2022

Проекторы и аксессуары

What is a mini projector (pico, portable, mobile), how to choose a portable projector model for a smartphone or laptop, connection features. A mini projector is a somewhat simplified version of a stationary multimedia
projector .. Due to their size and modest weight, they can be carried anywhere, displaying the image anywhere on a suitable flat surface. Despite the modesty of external parameters, these gadgets are almost in no way inferior to full-size models in their functionality. The source of the image in mini-projectors is an electronically controlled modulator, it receives a video signal from a computer. Projection devices allow you to display an image not only from a laptop or smartphone monitor, but can also have built-in memory and connect to the Internet. Mini projectors are primarily used for presentation purposes, gaining more and more popularity in various areas of business, education and science. They are also gaining popularity as home and mobile video projectors to watch videos in a convenient location.

Varieties of portable mini projectors

The easiest way is to divide the projectors into three groups, combined according to the features of use, size and properties:

  1. The smallest are pico projectors . The area of ​​their use is rather narrow, since the maximum area of ​​the projected image is about 50 cm. They can be used in small darkened rooms. In most cases, this is a good toy.
  2. Pocket projectors are slightly larger than the average smartphone. They are ideal for use with small groups (10-15 people). They use LED-lamps with a power of 100-300 lumens. The diagonal of the projected image rarely exceeds 100 cm. The image quality in such projectors is 1024×768 pixels.
  3. Portable or mobile projectors are a smaller version of a conventional projector. Their size rarely exceeds 30 centimeters, and their weight is 3 kg. Its design almost does not differ from the full-size version, although it may be slightly inferior in quality to the displayed image. They are equipped with conventional lamps, the resource of which is 2000-6000 hours, with a power of 3000-3500 lumens.

Standalone projectors can be singled out as a separate group, as they can “read” information directly from a flash drive or memory card.

Connecting a portable projector to a laptop, tablet or smartphone

Almost all projectors are equipped with special interface cables for connecting to a data source. Almost all models of modern laptops have a standard HDMI connector, mini-HDMI and micro-HDMI are less common. Usually this connector is located on the laptop on the left.

Connecting a portable projector via hdmi cable via an adapter [/ caption] depending on the laptop model. Using the Win + P combination, you can call up a vertical menu in which you can select the type of image output. For example, “Only computer” – the image will be displayed only on the laptop screen; “Duplicate” – the contents of the monitor will be the same on both screens; “Expand” – the desktop will increase on both screens (the left side on the computer, the right side on the projector); “Projector only” – the projector will become the main monitor (in this case, nothing will be shown on the laptop screen). When the projector is turned off, the image will revert to its original state. In some cases, connecting via a cable is difficult or even impossible. For such cases, there is a wireless connection. Depending on the projector model, this feature may be built-in or you will need a special Wi-Fi dongle, which requires two inputs (HDMI connector for data transfer and USB port for power). To pair with a projector on a laptop, select “Connect to a wireless display” in the screen menu, after which a vertical menu will appear on the right – a list of detected devices.

They do not take up much space, you can easily take with you on any trip. Smartphone and tablet also support wired and wireless connection. To control the mini projector using a smartphone, you need to specify the Wi-Fi signal source to which the smartphone will connect in the projector settings as a signal source. In a phone with Android OS version 4.2.2 and higher, there is a “Wireless Projection” item in the system settings of the screen. It is worth noting that both gadgets must be connected to a sufficiently fast WiFi network in order to avoid delays in data transfer.

How to choose a mini projector – what to look for, specifications

There are many different models of mini-projectors on the technology market. And in order to choose exactly the one that is able to solve the tasks for which it is purchased, you have to go through a large number of options. A good technique should perform the assigned tasks in accordance with the user’s requests. The choice of mini-projectors has to be approached more thoroughly, since their average cost is quite high.

Screen size

It is this parameter that most often pays attention to, because. The size of the projected image is important when dealing with an audience. But it’s also not worth striving for some unthinkable diagonals, because. Stretching an image often has a negative effect on image quality.

Calculate the optimal screen area: S=M/500, where M is the projector power (lm) and S is the screen area. You can also use the inverse formula, choosing the power of the projector according to the desired screen area (M=500xS). The result will, of course, be approximate, but quite reliable.

Light source and light output

The light source is mercury, xenon, LED lamps and lasers. In mini projectors, the use of lasers and LEDs is optimal, as they are more economical and have a small size. It is important to know and take into account the indicator of useful illumination. The higher it is, the brighter the projected image will be. For a darkened room, a projector with a low power (at least 100 lux) is also suitable, and if a presentation is planned in good daylight, then the desired power is already increased several times (400-500 lux).

Matrix type

This parameter is not paid much attention to. But it is the matrix that determines the quality of the image on the screen. Mini projectors use the following types of matrices:

  • mirror (DLP) , the pluses of which include compactness and good contrast, and the minuses are average brightness, the possibility of iridescent streaks on the screen;
  • liquid crystal (3LCD) , they are slightly worse than the first option in terms of contrast, but they produce a brighter image and are not subject to the rainbow effect;
  • combined (LCoS) , combining the advantages of DLP and 3LCD matrices in their design, this combination allows you to provide the maximum picture quality, but the price of such projectors will be quite high.

Most mini-projectors are single-matrix. But there are also three-matrix models among compact models, which can combine various types.

Focal length

This is the distance between the screen and the projector. An indicator that in some cases becomes very important. For example, if during the presentation there is a need to interact with the picture and the speaker should not cover the flow of light. Or if the projector is purchased to work in a small room (children’s projectors are often used in a car, mini-house, etc.). In these cases, preference should be given to short-focus models.

Permission

The clarity of the picture, which directly depends on the resolution of the projector, is one of the most important points for choosing a projector. Of course, 4K (3840×2160 pc) is great, but FullHD (1920×1080 pc) or HD (1280×720 pc) is more common. Lower resolution is also found, especially if the picture must be projected onto a small screen. For business presentations, watching video content, you need a high-quality picture, so it’s best to choose Full HD (1920×1080). In this case, the quality of the original image can be reduced during projection, but it can no longer be increased.

Noise level

Silent models do not exist. When you need a projector for quiet work (for example, to use it as a cinema). In such cases, you should choose models with a noise level of about 40 decibels (normal calm speech, a working computer).

Connection options

Since mobile projectors are usually connected to a laptop, it is optimal for most to have HDMI or VGA inputs for connecting to a signal source. With other outputs (video and audio), the capabilities of the projectors are expanded. If the projector has the ability to connect media via USB, then you can start the projection without an “intermediary”, which is very convenient when the owner is highly mobile. The presence of Wi-Fi allows you to provide access to the Internet (watch videos on YouTube or in an online cinema, for example), and using Bluetooth, you can synchronize the gadget with any smartphone or tablet.

autonomy

Mini-projectors are interesting for their mobility and independence from the source of electricity. Accordingly, battery life is often a critical parameter to choose from. Most often, Li-ion batteries are used, which differ in capacity (A * h – ampere hours). The higher the capacity value, the longer the projector will be able to work on a single charge. But it also increases the cost of technology. Therefore, if you need to buy a mini-projector for watching movies or long conferences, then you need to choose a device with a large battery. In the event that the projector is intended for short cartoons and presentations, then the issue of the duration of autonomy fades into the background.

Mini projectors for home: features of choice

A home projector is an opportunity to organize a home theater, watch and play computer games with the least damage to your health. Before buying a projector, you should consider where and for what purposes it will be used. To choose the perfect home projector, it is advisable to pay special attention to the brightness (DLP – at least 5000, 3LCD – 2500 lumens). For computer games, an important parameter is the frame rate (input lag), with a maximum value of 20 ms. The power of the projector for organizing a full-fledged movie viewing or gaming should be at least 200-250 watts.

Everycom S6 plus

The modest dimensions (81x18x147 mm) do not lower the quality of its work. The most important advantage of the projector is the use of DLP technology with a Laser-LED light source. Separately, it is worth mentioning the ability of the projector to correct keystone distortion. This function is not available in all modifications of Everycom S6 plus. The amount of RAM can serve as a guideline. There are modifications with 8, 16 or 32 GB of RAM. The youngest with 8 GB does not know how to correct trapezoid distortions, the other two do it automatically. A separate explanation on the HDMI interface. In modifications with 8/16 GB RAM, HDMI works as a TV set-top box. On models with 32 GB of RAM, HDMI can be used to connect the projector to a PC or laptop, game console, and other compatible devices.
