The speed is different. 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.
The principle is different. 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.
The 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.
The price is different. Fast charging devices are slightly more expensive than slow charging devices. The difference is about 20 to 50.
The difference between fast charging and slow charging is: different current, different charging time, and different temperature.
< br \/ >
First, the current is different
< br \/ >
1, fast charge: Fast charge is the use of 30%C current to charge the battery.
< br \/ >
2, slow charge: slow charge is the use of 10%C current to charge the battery.
< br \/ >
Second, the charging time is different
< br \/ >
1, fast charge: the charging time of fast charge is the same appliance, fast charge a charge is shorter than slow charge a charge, fast charge higher charging efficiency.
< br \/ >
2, slow charge: slow charge charging time is the same appliance, slow charge a charge time is longer than fast charge a charge, slow charge charging efficiency is lower.
