· When charging your phone, you should first plug the charger into the power source before connecting the phone

When charging a mobile phone, should the charger be connected to the phone first or plugged in power source first? The correct answer is to first connect the charger plug to the power source, and then connect the data cable to the phone.What is the impact of the order in which the charger is connected to the power source and the phone on the battery？Here we need to introduce a knowledge point: the voltage of electricity used by Chinese residents is 220V, but the voltage of mobile phone chargers is often within 5V. When charging mobile phones, the charger will convert the high-voltage current through a transformer into low-voltage DC and then transmit it to the phone.At this point, if the charger is connected to the phone and then plugged into the power supply, it can be considered as directly connecting the phone to the power supply, which may output surge voltage; On the other hand, by inserting the plug first, it is already in a connected state and the output has stabilized...

· Can you keep the laptop plugged in?

Can a laptop always be plugged in? Some people use laptops in the office or at home all year round, with the computer constantly plugged in and the battery level maintained at 100%. One thing to worry about when doing this is that keeping the lithium battery fully charged for a long time may cause battery passivation and affect battery capacity.So for friends who always plug their laptops in, our suggestion is to occasionally unplug the power and use the battery. After all, you cannot guarantee that there will always be a power source available. Maintaining the battery will prolong its lifespan. Remember to plug it back in promptly, otherwise it may suddenly run out of power and shut down, and any unsaved items may be lost.Can I turn off my computer when it runs out of battery?Most laptops nowadays use lithium batteries, and some people worry that deep or even excessive discharge of the battery may irreversibly damage it. Although there is some truth to this concern, there is no ne...

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...

· How to charge your phone correctly?

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...

· Do mobile phone need to be fully charged?

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...
