Common laptop power adapters are 90W and 60W. If you want to power or even charge a laptop using a 90W power adapter, the output current of your power bank must be sufficient. large, otherwise the computer will automatically reduce performance to save power. ) times the voltage.
For example, the capacity of a 6-cell laptop battery is 56WH and the battery of a power bank is 10000mAH. Then the capacity of the power bank is:10000mAH/1000×3.7=37WH。显然这个充电宝是不够用的。In the past, the thickness of laptops became a major pain point. For a better user experience, notebooks are becoming thinner and lighter, and the charging interface of notebooks has been upgraded from USB Type-A to Typc-C. However, it solves the pain point of heavy notebooks, but sacrifices the capacity of the notebook battery. The battery capacity is smaller than before and cannot support long-term use of electricity when going out, and ordinary power bank cannot charge the notebook. , notebook battery life has become a pain in the hearts of users. Fortunately, Nanfu recently launched a professional-grade notebook power bank, which can be used with Typc-C data cables to charge Apple Mac Book, Huawei MateBook and other Typc-C interface notebook devices. In terms of charging speed, this laptop power bank named Xiaojia uses PD2.0 two-way fast charging, achieving an astonishing 45W high-power fast charging. It only takes 2.5 hours to fully charge the power bank itself. Nearly 5 times faster than ordinary power bank. In terms of output voltage, this power bank has intelligent variable frequency fast charging technology, which can intelligently adapt to various electronic devices within the 0-20V range, such as 5V2A, 5V3A, 9V3A, 12V3A, 15V2.6A, 20V2 .5A can be supported, truly realizing fully compatible fast charging technology. So in addition to charging laptops, this product is also fully compatible with smartphones, tablets and other products, and can even charge the most popular Switch game console (15V2.6A). Due to its large capacity of 20100 mAh, it can fully charge the Switch 3 times. From now on, if you take a Xiaojia laptop power bank with you when you go out, you can keep the battery life of most electronic devices.
