What does 2a charger mean?

2a charger refers to a charging head with a maximum output current of 2a. The output current of the 2A charger is larger than that of the 1A charger. If the output current of the original charger of the mobile phone is 1A, then use a 1A data cable; if you use a 2A data cable, you will find that the charging time is shortened and the mobile phone is charged. When it gets hotter, the cell phone battery may bulge, shorten battery life, and pose safety risks when charging.

What does 2a charger mean?

2a charger refers to a charging head whose maximum output current is 2a. The charger will be equipped with different plugs depending on the mobile phone or model, and the charging head is often equipped with only one or more USB sockets with current output.

The output current of a 2A charger is larger than that of a 1A charger. If the output current of the original charger of the mobile phone is 1A, then use a 1A data cable. If you use a 2A data cable, you will find that the charging time is shortened, the phone gets hotter when charging, the phone battery may bulge, the battery life is shortened, and there are safety hazards during charging. Generally, 1A and 2A data in a short time There is not much difference in the lines. However, generally good mobile phones have charging protection circuits inside, so it will be fine even if a 2A data cable is used on a 1A mobile phone. It is best to use the original charger and data cable. Because some data cables have lock codes inside, different mobile phones cannot be mixed.

#2a charger is how many w

2a charger is 10w. The output voltage of the smartphone charger is 5V and the output current is 1~2A. Therefore, the output power is 5~10W. As for feature phones, due to their smaller batteries, the output current is 0.5A and the output power is about 2.5W. The charging method of nickel-metal hydride batteries uses constant current. The nickel-metal hydride battery itself is not afraid of overcharging. When the nickel-metal hydride battery is overcharged, there will be a reverse reaction to prevent the voltage from rising excessively. This reaction will cause the battery to heat slightly. In addition, NiMH batteries usually have a thermistor added to prevent overcharging of the battery. The working voltage of most mobile phones is about 3.6V, so three nickel-metal hydride battery cells are required. The nickel-metal hydride battery cell stops when it is overcharged to about 1.4~1.5V, and the maximum voltage of the three-cell battery is about 4.4V.

Power refers to the amount of work done by an object in unit time, that is, power is a physical quantity that describes the speed of doing work. The amount of work is fixed, and the shorter the time, the greater the power value. The formula for finding power is power = work/time. Power is a physical quantity that represents the speed of work. The work done per unit time is called power, represented by P. Therefore, power is equal to the scalar product of the force and the velocity of the point on which the force is applied.
