The charging current of fast charge is large, so the charging time will be much shorter; The charging current of slow charge is small, so the charging time is long.
For example, if you buy a nickel-metal hydride charger, which is marked with output current of 1.5A, this is fast charging, because the current 5 nickel-metal hydride battery capacity is more than 2500mAh (2.5Ah), with 1.5A current charging, about two hours will be full; If the charger you buy is marked with output current of 100mA or 200mA, it is slow charging, and it will take about twenty or thirty hours to charge the 2500mAh battery, and it may not turn the lamp after full (the current is too small to detect). As for the damage of the fast charge to the battery, it theoretically exists, because the large current charging heat is large, and the chemical material composition in the battery has the possibility of accelerating the life consumption.
However, in order to save efficiency, this effect can generally be ignored (the battery cycle is generally 300-500 times, which can be used for so long is very energy-saving and emission reduction).
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. Different quality. 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. The price is different. Fast charging appliances are slightly more expensive than slow charging appliances, with a difference of about 20 to 50.

The above is about the difference between fast charging and slow charging of the charging bank. Through the above, I believe that everyone has an understanding, and I hope it will be useful to you.
