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.

GaN Fast Charger   MW-OH-D7 Product Description Model: MW-OH-D7 NavitasGaN Fast Charger + PD3.0 Input: AC 100-240V 1.5A 50/60Hz Type-C Output (Max 65W): DC 5V/3A, 9V/3A,12V/3A,15V/3A,20V/3.25A USB-A Output (Max 12W): DC 5V/2.4A Dual-port Output：Max 57W (45W+12W) Total Output: 65W Size: 50.8*51.9*29.4mm Weight: 109g Features: - The GaN fast charger  for all your charging needs - The smaller size and stronger charging current thanks to new GaN technology - Support full quick charge protocols, including PD3.0, QC4+, QC3.0, AFC. MTK. etc. - The maximum output power of 65W for charging notebooks and laptops - One Type-C ports and one USB enables charging two devices at the same time Why Do Fast Chargers Need GaN ? There are some fundamental reasons why GaN will replace silicon, but the key feature is very obvious-it is more than 100 times faster than silicon, which means smaller, lighter, and cheaper chargers.

    At present, 18650 battery technology is more mature, its battery structure is stable, high specific capacity, outstanding overall performance, small size, wide range of applications. However, its safety is worse than lithium polymer batteries, and the number of cycles of the cell is low, about 300 times.   The main advantages of  polymer batteries . (1) Long service life. Charge and discharge more than 500 times without problems. (2) Diversified appearance, the use of 18650 battery products are thick and large, the shape of the millennium remains unchanged. (3) safe to use, mostly used in high-end products. The safety of polymer batteries is reflected in the non-explosion, only bulging, spontaneous combustion and other possible occurrences. (4) high capacity, in the same package volume (note, package volume), polymer batteries can store more power, so most lighter and thinner, good portability, directly enhance the user's experience. (5) The disadvantage is the h...

Mobile power supply (MPP), also known as rechargeable battery, travel charger, etc., is a portable charger that combines power supply and charging functions in one. It can charge cell phones, tablets and other digital devices anytime and anywhere. Generally use lithium battery (or dry cell, less common) as the power storage unit, easy to use and fast. Mobile power cells are mainly divided into 18650 cells and polymer cells. The most common on the market is 18650 lithium-ion batteries, with a market share of 70%.     At present, 18650 battery technology is more mature, its battery structure is stable, high specific capacity, outstanding overall performance, small size, wide range of applications.

We analyzed the power consumption of different smartphone components in a series of typical scenarios. We concluded that there are some simple software and hardware strategies that can be used to extend battery life. ✱ Reduce screen brightness. The easiest way to extend battery life while maintaining full functionality is to reduce screen brightness. For devices with organic light-emitting diode (OLED) displays, you can also use the "bright when dark" option to see. ✱ Turn off cellular networks or limit talk time. The connection to the cellular network uses the Global System for Mobile Communications (GSM) module. GSM is the primary energy-consuming component of the phone, so it is beneficial to turn it off completely or at least limit talk time. ✱ Use Wi-Fi instead of 4G. Wi-Fi uses up to 40% less power for Internet browsing compared to 4G, so turning off cellular data and switching to Wi-Fi will help extend battery life. ✱ Limit video content. Video processing is one of the...

As cell phone users, all we want is enough battery life. Frustratingly, the older a device is, the less power it seems to have. In fact, the battery life of our phones on any given day depends on two key factors: how we use them on that particular day, and how we've used them in the past. Cell phones use lithium-ion batteries for energy storage. In this type of battery, lithium metal and lithium ions move in and out of the individual electrodes, causing them to physically expand and contract. Unfortunately, these processes are not fully reversible, and as the number of charge and discharge cycles increases, the battery loses its charge capacity and voltage.     To make matters worse, the electrolyte (conductive liquid) that connects the electrodes also degrades during these cycles. The ability of a lithium-ion battery to store charge depends on its degree of degradation. This means there is a link between the way we handle our devices today and the charge capacity available in...
