1, Recently Lenovo new Pro 14 2021 launched, Lenovo is also equipped with a new generation of fast charger, with its own USB-C cable output power 65W, also keep it small and portable. Lenovo new Pro 14 2021 standard 65W PD charger, different from the old big black brick, this charger compact design, using the current mainstream white bright surface appearance, the charger comes with USB-C cable, the maximum output power 65W, support USB PD fast charging standard.
2, Millet 65W: with Redmi redmibook Air, Millet Notebook Pro and Lenovo new Pro 16 one plus mobile phone 65W: also applicable to the above devices Bysi 100W: cover the above notebook is worth notingMobile phone charger and laptop charging compatibility depends on the charging protocol. Most PD protocol chargers above 60W can meet the demand, but the test sample is limited, and more products have not yet been verified. Xiaomi's and Bex's gallium nitride charging heads performed well in tests.
3, Lenovo a series of computer sound performance is good, Harman audio Dolby sound is basically becoming the standard Lenovo computer. The performance of the small new Air15 dual speakers is also commendable. The cooling module of the small new Air15 has not shrunk because it is a thin book, and the dual fan (the fan uses an ultra-thin blade design,The use of ultra-stiff crystalline polymer LCP reduces fan thickness by 30% and improves performance by 20%.
4, hardware configuration: Lenovo new air15 2022 equipped with the latest Intel core 12 generation i5 1240p and i7 1260p processors, in terms of performance performance is still relatively strong, memory is 16GB DDR4, hard disk 512GB high-speed solid-state drive, the graphics card is sharp xe core display.
First thinkplus wireless fast charge , Lenovo simple science under the knowledge of notebook battery thinkplus wireless fast charge : Lithium-ion battery is a commonly used battery, the physics teacher said, it mainly relies on lithium ions to move between the positive and negative terminals to work. (As shown in the figure) Therefore, the two actions of charging and discharging have a great impact on the battery. The batteries used in mobile phones and laptops now belong to lithium-ion batteries, and lithium batteries themselves are relatively "delicate".
First, 45W chargers are usually designed for light and thin laptops, such as Lenovo's ThinkPad X1 Carbon or some models in the IdeaPad family. Since these laptops are usually more focused on portability and battery life, their charger power is relatively low to reduce the size and weight of the charger, which is convenient for users to carry around. Second, the 65W charger is one of the most common models in Lenovo laptops.
The design style of the charger is stable and atmospheric, using thinkplusWireless fast charge Black tone, the volume compared to the traditional 45W or 65W style has increased, which is a direct reflection of power improvement. At present, the detailed specifications of the charger, such as the protocol and PDO voltage gear, are still unclear, but it is foreseeable that it will bring users a more convenient charging experience.
1. Bone conduction and gas conduction are two different transmission modes of open earphones. Bone conduction through vibration of the boneThe sound is delivered to the inner ear without the need to pass the sound through the ear canal to the ear. In contrast, air conduction is the transmission of sound directly through the ear canal to the inner ear. While bone conduction and air conduction are both open headset technologies, bone conduction has some advantages that make it more recommended.
2, therefore, the difference between open earphones and bone conduction earphones is that bone conduction earphones are open earphones, and open is roughly divided into two categories, respectively, air conduction and bone conduction, both of which are open is very different, below I will briefly introduce the difference between the two.
3. OpenThe biggest difference between headphones and bone conduction headphones is the different way of wearing and the different way of transmitting sound, compared with bone conduction headphones are more worth buying. But in fact, bone conduction earphones are also open earphones, the following first understand what kinds of open earphones. What are the types of open headphones? Open headphones are divided into air conduction and bone conduction.
4, open ear design and closed ear plugs are different, bone conduction headphones let your ears remain open, reducing the direct pressure on the ear canal and eardrum, which undoubtedly reduces the burden on the ears. However, for volume control, bone conduction headphones and ordinary headphones are not fundamentally different, too much
