The capacity of your power bank determines how often you're able to charge your smartphone, tablet, or laptop. As with smartphone batteries, the capacity is expressed in in milliamps per hour. But you can't simply compare the capacity of a power bank with that of other devices. Due to energy loss during charging, about 1/3 of the capacity of a power bank is lost. Here, you can read how this works. 1/3 of the capacity is lost The technical side of it is complicated, but the rule is simple: the actual capacity of a power bank is about 2/3 of the capacity indicated. The rest disappears during power conversion or is lost during charging, especially as heat. This means power banks with a battery of 10,000mAh or 20,000mAh actually have a capacity of only 6,660mAh or 13,330mAh. This rule applies to high-quality power banks alone. Budget power banks from cheap wholesalers are even less efficient, so they lose even more energy.   Smartphones: a power bank with 10,000mAh With a 10,000mAh...

Early mobile power gives most users the impression that it is big and heavy, while today's mobile power is very small, especially the shared ones. Those who have used them will feel very light. This is a credit to the polymer lithium-ion battery. In fact, many electronics can perform better thanks to polymer lithium-ion batteries, such as TWS Bluetooth headphones and special small electronic devices. Unlike a few years ago, fewer and fewer 18650 lithium-ion batteries are used in   power banks . Are they really being phased out? Besides size and weight, what is the difference between polymer Li-ion batteries and 18650? That's what we'll discuss today.     What is an 18650? There are two important types of batteries on the market today, one is the lithium-ion battery and the other is the polymer battery. Lithium-ion batteries generally refer to aluminum-cased batteries, the electrolyte is liquid, and the outer packaging material is aluminum case or nickel-plated With the co...

    The difference between plugging in and unplugging the laptop power adapter There is almost no difference between plugging in and unplugging the power adapter when the laptop is turned off. If the power adapter is plugged in all the time, there will be a power drop and it will consume more power than if it is not plugged in. Many laptops have indicator lights on the power switch button. When always plugged in, the light will stay on, indicating that the laptop is plugged in. If it is not plugged in, the light will go off. There is no other difference.   However, if the laptop is in working condition and the power adapter is unplugged, the situation is very different. Most laptops automatically go into power saving mode, which affects the brightness of the display and the performance of the computer.   Why would anyone recommend "unplugging"? The advice is good, but it is necessary to find out why it is recommended. The laptop's power adapter converts residential e...

Many users of laptops have a question, "Do laptops need to be plugged in all the time?" . This article revolves around this issue, to discuss my own views.   Do laptops have to be plugged in all the time? Although laptops are equipped with an extra battery, the battery life is usually around 2 to 4 hours, and the battery is generally used as a backup power source. the IC system will prioritize the use of power from the laptop power adapter based on the connection status of  the power supply , and will also charge the battery.   But this is only when the laptop is working. If the user is not using the laptop, he can also unplug it without having to keep it plugged into the computer.
