As the preferred choice for daily office work, the battery life of laptops is very important. However, most original power adapters have a large size and are not convenient to carry when going out. Therefore, choosing a compact power adapter is very important. Below, we will introduce the current laptop power adapter products on the market from the aspects of power, interface, etc., and also provide some suggestions for your purchase, hoping to help you choose suitable products.Classification1. Power(1) 65W and belowThe output power is within 65W, mostly 65W, mainly used to power lightweight laptops. Their hardware configuration is relatively low, and the power consumption of each hardware is not high, so 65W is sufficient. And this power adapter has a small size and high portability. (2) 66-120WMainly used for high-performance lightweight laptops, mostly with standard voltage processors, power consumption can reach 35, 45, or even higher. Some models are also equipped with entry-lev...

According to a report by Global Network Technology on March 1st, mobile phone batteries do not like to be in a 100% saturation state for a long time. Charging to 80% to 90% is sufficient. It is more beneficial to charge a small amount multiple times, but also to avoid excessive discharge. Do not wait until the battery is depleted before charging, as excessive discharge can shorten the battery life.According to People's Daily, in fact, mobile phone batteries don't like to be in a 100% saturated state. Did you charge them correctly? People's Daily reminds:① Charging only when the battery is depleted will reduce the battery life;② Mobile phone batteries do not like to be in a 100% saturated state. Charging them to 80% to 90% is sufficient, and a small amount of multiple charges is better for the battery;③ Lithium batteries are afraid of heat, keeping phones away from heat sources;④ Don't always use the power bank to charge;⑤ Don't always use USB to connect your computer for charging.The...
No need, 80-90% is sufficient, leave some room for improvement! In our daily lives, mobile phones have become an indispensable part. To ensure that our phones can serve us anytime, anywhere, we often charge them. But you know what? Incorrect charging methods may have a negative impact on the battery life of mobile phones. So, how to properly charge your phone and extend the battery life? 1. In those years, we went through the charging misconceptionsMany people habitually charge their phones to 100% before unplugging them. They believe this is the best protection for the battery. But in fact, this approach is not scientific. The charging principle of lithium batteries is different from that of older batteries in the past, and overcharging can actually shorten the battery's lifespan.(1) Overcharging can cause the electrolyte inside the battery to decompose, forming needle shaped crystals on the positive electrode. These crystals may puncture the battery separator, causing dangerous s...
Charging time is a major consideration for consumers and businesses when evaluating the purchase of electric vehicles (EVs). In order to shorten charging time, the industry is turning to using DC charging stations (DCFCs). DCFC bypasses the onboard charger of electric vehicles and directly provides higher power to the battery, greatly reducing charging time.In order to achieve faster charging speed, adapt to higher voltage of electric vehicle batteries, and improve overall energy efficiency, DCFCs must operate at higher voltage and power levels. This poses a challenge for OEMs, as they must design an architecture that can optimize efficiency without compromising reliability and security.DCFC integrates multiple devices, including those used for auxiliary power supply, sensing, power management, connection, and communication. In addition, in order to meet the constantly evolving charging needs of various electric vehicles, flexible manufacturing methods must be adopted, which also make...
In recent years, with the popularity of mobile devices and the continuous growth of functional requirements, traditional HDMI and USB interfaces have gradually exposed some inconveniences. To address these issues, the Type-C interface has emerged. Its emergence not only makes connection more convenient, but also brings many new functions and features. Next, we will compare the Type-C interface with HDMI and USB interfaces one by one.1.Comparison between Type-C interface and HDMI interface Higher data transmission speedCurrently, the popular HDMI interface on the market usually adopts the HDMI 2.0 standard, supporting a maximum data transmission speed of 18 Gbps. The Type-C interface supports protocols such as USB 3.1 Gen 2 and Thunderbolt 3, achieving a data transfer speed of up to 40 Gbps, providing a better video and audio transfer experience.Smaller physical interface shapeThe Type-C interface adopts a unified inverted design, which can achieve forward and reverse insertion, and...
