I believe that many people have experienced cell phone without a battery, especially on the road, the mobile phone is no electricity led to upset; and for many business people who need to travel frequently, the laptop battery capacity is always not enough, how to do it ?

       In fact, the notebook can also be a mobile power like a smartphone.

       Currently, the mobile power supply for notebooks such as Hewlett-Packard, Lenovo, and Asus are mainly divided into two types: one is a DC or USB output, and the other is a dual USB output. The difference between the two prices is nearly doubled. When the DC input is charged, it is similar to the type of interface that is directly plugged into the external power supply. The voltage is 19V DC. Most notebook adapters are also 19V output voltage; the other is USB input,and currently do not know How it is used, but the price is cheap. How to choose specifically?

       The main mobile power source for notebooks is the capacity and use of mobile power.

       How much of a mobile power source you feel is suitable for use depends on how good your product is. If you use a laptop, you must choose a large capacity, otherwise it will be short-lived and the key moment will be dead.

       And choose a large-capacity mobile power, mobile phones, laptops and other digital products can share a power supply, the brand's good mobile power prices have more endurance and stability, the price is relatively expensive.

       At present, the number of notebook mobile power brands is relatively small, but the mobile power of big-name notebooks is generally more expensive. The largest notebook mobile power brand in China is the mostfamous Lenovo brand in China, occupying half of the domestic market. Followed by E-core and HP notebook mobile power.
