A power bank with a 2.1A output is not necessarily a fast charge, because fast charge means that the charger or charging device supports a fast charging protocol and technology, which can quickly fill the battery. The power bank is a kind of mobile power supply, which only transmits electricity to the mobile phone or other electronic devices through the output current, and does not involve the fast charging protocol and technology.

In general, the higher the output current of the charging treasure, the faster the charging speed, but the specific charging speed is also affected by factors such as mobile phone battery capacity, charging line quality, charging treasure battery capacity and charging speed of the charging treasure itself.

If you want to achieve fast charging, you need to make sure that your charger bank and phone support fast charging protocols and technologies, and use the appropriate fast charging cables and chargers. At the same time, it is also necessary to pay attention to the compatibility of the charging bank and the mobile phone, so as to avoid abnormal charging.
The answer is: the power bank output 2.1 amps is not fast charge.
The reason is: there are many kinds of fast charging technology, among which the common ones are QC, PD,
SCP, etc., these technologies have different voltage and current standards,
and the 2.1 amp output does not clearly indicate which fast charging technology is supported.
Therefore, it does not count as a fast charge.
If you need to use fast charge, it is recommended to choose a charging bank marked with fast charge technology,
so that the charging speed is faster.
Not necessarily. 2.1 Amps is a high current output, but the definition of fast charge depends on the protocol and compatibility between the charging device and the charging bank.
If the charging bank and the device support the same fast charging protocol (such as QC, PD, PE, etc.), fast charging can be achieved. If the same protocol is not supported, fast charging cannot be implemented.
For this matter, a 2.1 amp output current can be considered a fast charge, but this depends on the maximum charge current supported by the device being charged. If the device supports a higher charging current, then a 2.1 amp output current is not considered a fast charge. In general, fast charging requires higher output current and special charging protocols, such as QC, PD, etc.
On this issue, the 2.1 amp output does not necessarily represent fast charge, it is only the size of the output current, fast charge also needs to consider the output voltage, charging protocol and other factors. For ordinary mobile phones, the fast charge standard is generally 5V\/2A or 9V\/2A, and the output current of 2.1A cannot meet this standard. Therefore, the power bank output 2.1 Ann is not necessarily a fast charge.
Not necessarily a fast charge.
Because the standard of fast charge is based on the specific equipment, different manufacturers have different definitions of fast charge. Generally, most mobile phone manufacturers' standard for fast charge is 5V\/2A or 9V\/1.67A, while Apple's standard for fast charge is 5V\/2.4A.
Therefore, it is necessary to check whether the fast charge standard of your device meets the output of 2.1A in order to determine whether the charging bank supports fast charge.
In addition, the larger the output current will have a greater impact on the equipment, so it is necessary to pay attention not to overuse to avoid damaging the equipment.
It's not a fast charge.
Because the fast charge output is usually 5V\/2.4A and above, and the charging treasure output 2.1A only meets the fast charge cable's support for the fast charge protocol, the actual speed is still the speed of ordinary charging, so it cannot be regarded as fast charge. In addition, in most cases, the output voltage and current of the charger that charges the mobile phone battery the fastest need to match the nominal value of the battery, otherwise too high or too low will damage the battery life.
1 is not a fast charge.
2 Fast charge technology needs the corresponding standards and special supporting, and the ordinary charger can only provide 2.1A output current, this output can not be called fast charge.
3 If you want to experience fast charging, it is recommended to use chargers and devices that meet the fast charging standard to charge your device more quickly.
Under normal circumstances, the power bank output 2.1 amps is not fast charging, because fast charging requires the use of a specific fast charging protocol and compatible equipment to achieve fast charging. For example, Apple's Fast Charge requires the use of Apple's original fast charge adapter and Lightning-to-USB-C cable for fast charging. Therefore, if you need a fast charge, it is recommended to use a compatible fast charge adapter and charging cable, which can charge your device faster.
It's a fast charge.
Charging banks on the market now generally have two interfaces. One charging port is 1A, and the other charging bank is two amps. We generally default that 2.1 amps is fast charge. And the 2.1-amp interface does charge much faster than the 1-amp interface.
Yes, it is fast charging, because the charging voltage is high, the power is very large, the charging treasure can reach 66 watts of fast charging when the output of 2.1 amPs current, and the voltage can reach seven volts, so it is very fast
