Convenient for “mobile office”, Lenovo (ThinkVision) SEI 15 monitor doubles productivity

With the gradual maturity of Internet technology and the popularization of 5G technology, “mobile office” has become a new trend. For financial practitioners, advertising practitioners, BD, sales and other “flying trapeze” who often deal with data, mobile office is even more commonplace. However, only a “notebook” can not meet the increasing office needs, especially most notebooks are 13 or 14 inches in size, and the display effect is slightly insufficient. At this time, the “expansion screen” comes in handy. Display size, better portability, and more intelligent terminal connections, eliminating the trouble of “double-book office”. Today I want to introduce the mobile portable display produced by Lenovo (ThinkVision)-Siyi 15, designed for mobile office, making the road more efficient!

HD resolution, thin and portable
Compared with the mobile portable displays on the market, Lenovo (ThinkVision) Siyi 15 has been upgraded again in size-up to 15.6 inches, with FHD resolution, providing a better visual experience. Although the size has become larger, the portability of the Siyi 15 remains the same. It uses a three-sided narrow frame design. The thinnest point is only 6mm, and the body weight is only 860g, which is even less than the weight of a tablet and is suitable for multi-scene needs.

One-line connection, easy to expand
One of the troubles of the mobile portable screen is that its power consumption reduces the battery life of the notebook sharply, and the Siyi 15 with dual USB-C interfaces does not have this trouble.
The Siyi 15 with two USB-C ports can be connected to the laptop while being connected to the power supply. The advantage of this is that the power supply can supply power to the laptop through the Siyi 15, allowing users to easily manage the power supply of the portable display. Moreover, Siyi 15 also supports a first-line connection scheme, which is more compatible with notebooks, and is easier to connect and expand different smart devices while saving desktop space.

Intimate design, low blue light
In terms of detailed design, Lenovo (ThinkVision) Siyi 15 is also very intimate.It uses an integrated bracket design. No additional bracket is required when used. It can be opened and closed at a right angle of up to 90°, and the bracket can be adjusted in height and lift height. It supports up to 10mm to meet the needs of multiple scenarios and greatly enhance the comfort of use.

Siyi 15 also has an independent brightness adjustment button, which can be adjusted from 0 to 100%. Next to the brightness adjustment button is an independent anti-blue light mode switch, which can switch between low blue light mode and normal display mode with one button, which effectively protects eyesight and relieves eyes. Department of fatigue.

Getting used to “multi-screen mobile office” is necessary in this era of information explosion. On the one hand, we are surrounded by massive amounts of information every day, no matter whether it is actively acquired or passively received, there is an indispensable “window” that can carry it; on the other hand, the continuous progress of portable smart devices pursues “lightness” and “thinness”. As a result, interfaces usually rely on USB-C, which also makes it more difficult for traditional displays to connect to devices. The Lenovo (ThinkVision) Siyi 15 monitor can solve these “pain points” and effectively help the mobile office crowd to increase productivity.You can buy laptop batteries on

The new generation of iPad Air may be released in the fall, and the rear dual camera is similar to the iPad Pro

According to the practice of previous years, Apple will update the iPad Air product line this fall. Recently, some media quoted supply chain sources as saying that the design of the new iPad Air will be similar to the 11-inch iPad Pro. The front will still use a 10.9-inch screen, but the back will be upgraded to dual cameras.

   According to Apple’s product line planning, there will still be a certain gap between iPad Air and iPad Pro. Therefore, the new iPad Air will most likely not use the M1 chip, but will use the same A15 chip as the iPhone 13 series.
   There is another news that Apple will also introduce 5G network to the iPad Air product line this year. The new product unveiled this fall will become Apple’s first iPad Air to support 5G network. In terms of screen, the new iPad Air will still use a 60Hz screen, so users who have a higher demand for high refresh rate screens still need to choose iPad Pro.

It is worth noting that the new iPad mini that has been frequently exposed before will most likely not be released this year. The new iPad mini will adopt a new design. The overall shape is similar to the iPad Air newly released last year. It has a larger screen size and a comprehensive The screen design will bring users a better experience.You can buy mobile phone batteries on

What is fast charge? Is there any difference between fast charge battery and ordinary battery?

What is a fast charge battery?

Most of the fast-charging batteries on the market are lithium-ion batteries, so the fast charging generally refers to lithium-ion batteries. The charge-discharge rate of a lithium-ion battery determines how fast we can store a certain amount of energy in the battery, or how fast we can release the energy in the battery.
When charging, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure, which has many micropores for the insertion of lithium ions that reach the negative electrode.
The more lithium ions are inserted, the higher the charging capacity. During fast charging, lithium ions need to be quickly inserted into the negative electrode. This poses a great challenge to the negative electrode’s ability to quickly receive lithium ions. The battery of ordinary chemical system will have by-products in the negative electrode during fast charging, which will affect the cycle and stability of the battery. The core of the lithium battery fast charging technology is to accelerate the speed of lithium ions moving between the positive and negative electrodes through chemical system and design optimization without affecting the battery life and reliability.
Is there any difference between fast charge battery and ordinary battery?
Fast-charge battery refers to a battery that can be fully charged with 80% or 100% power in a short period of time. By changing the electrolyte formula of the battery itself, it can withstand a larger current and be fully charged in a short time. This is the biggest feature of fast charging batteries. Fast-charge batteries can be divided into lithium-ion batteries, button batteries, nickel-metal hydride, nickel-cadmium batteries, etc. according to their materials. The following are the differences between quick-charge batteries and ordinary batteries.
1. Extremely fast charging. For example, charge more than 80% of electricity in 15 minutes;
2. Ultra-long and durable: After 500 times of fast charging, it still maintains more than 80% of the capacity;
3. Safe and reliable: Comply with lithium battery safety standards such as IEC, UL, PSE, UN38.3, etc.;
4. Wide application: It can be customized and developed according to actual needs, and it is widely used in consumer electronics, toys and other electronic products.If you want to buy a fast charge battery, please buy it on

The new Apple display may have a built-in A13 chip to improve graphics performance

At the 2019 WWDC conference, Apple launched a new Pro Display XDR display, which is Apple’s first 32-inch 6K retina display with a peak brightness of 1600 nits and a contrast ratio of 1000000:1. Recently, there are media reports that Apple is about to launch a display that breaks through the Pro Display XDR. This display will have a built-in A13 bionic chip to improve graphics performance.

   In short, adding an A13 bionic chip to the monitor is similar to a built-in graphics card for the monitor. It can help Mac improve graphics performance, and can also reduce the burden on Mac’s built-in graphics card during daily use. According to another source, Apple can also develop its own applications, which can integrate the Mac’s SoC with the display’s SoC during use to further improve graphics performance.

   As early as 2016, it was reported that Apple was about to launch a display with a built-in graphics card, but until Apple launched Pro Display XDR in 2019, we did not see this display unveiled. However, there have been more revelations, so we are likely to see this display product with built-in graphics card in the near future.You can buy mobile phone batteries on
