1. Different speeds. Fast charge generally charges the phone, and it can charge 50 to 70 percent of the electricity every half hour. The slow charge takes two or three hours to reach 50 percent.

2. Different principles. Fast charge is to increase the current to achieve a rapid charge to the mobile phone, slow charge is ordinary charging, small flow to the mobile phone fully charged.

3. Quality is different. Fast charging appliances and slow charging appliances of the same price, fast charging appliances will break first, because the loss of fast charging appliances is larger.

4. Prices vary. Fast charging devices are slightly more expensive than slow charging devices. The difference is about 20 to 50
Control the difference between fast charging and slow charging wire, 30w charging wire diameter is relatively thin. Able to flow, charging current is small. 60w charging cable, the wire diameter is relatively thick. The charging current that can flow is relatively large. Therefore, the 60w charging cable should be used for the fast charge of the 60w charging head. The 30w charging cable should be used for the 30w slow charging head. There is a big difference between fast and slow charging of a battery. The time used to charge the fast head is very short. Slow punches take longer to charge.
