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).

The first step Huawei mobile phone fast charge and super fast charge a significant difference is that the charging output is different, fast charge is 9V-2A,...
two
The second step charge output is different, so the super fast charge is faster than the fast charge
three
Step 3 Fast charge and super fast charge charging icon is different, fast charge charging icon is a large and small double lightning,...
four
Step 4 According to the battery icon when charging, you can see whether the phone is fast charging or super fast charging
The difference between fast charging and super fast charging, let's take a look at the difference between fast charging and super fast charging.
First, the difference in ICONS
Fast charge mode When charging, the phone power display area has a large and a small lightning symbol.
Super Fast Charge mode When charging, the phone power display area has a large lightning symbol.
Second, the use of chargers is different
Fast charging can be achieved using other ordinary fast charging appliances, and is also compatible with other fast charging and ordinary charging protocols.
Huawei Super Fast Charge is a technology that integrates high voltage fast charge, low voltage and high current direct charge, USB, and PD, which can solve the compatibility between different fast charge protocols.
