1, charging speed is different
< br >
When charging a mobile phone, the charging speed is often very fast, basically every half an hour can be charged 50%-70% of the electricity, and the battery can be full soon, while the slow charging speed is slow, it takes 2-3 hours to charge the battery to 80% or full.

2. Different principles
< br >
Fast charging is generally achieved by increasing the current to quickly fill the battery, and slow charging is ordinary charging, the current is relatively small, so the damage to the battery is not so large, and the service life is longer.

3. Different quality
< br >
In the case of the same price, the fast charger will be easier and faster than the slow charger, and the service life is not long, because the fast charger will lose more in the process of use. In addition, fast charging appliances on the market are more expensive than slow charging appliances
Fast charging needs, mobile phones, charging cables, charging heads, all meet the requirements to fast charging. The essential difference between fast charging and slow charging is the charging efficiency. The fast charging efficiency is high, and the power rushed into the same time is large.
