What is the difference between data lines 2a and 5a?

Difference: 1. 2a charges slowly, but the conversion efficiency is higher than 5a; 5a has a larger current and charges faster. 2. 5A supports a maximum of 240W electrical appliances, and 2A supports a maximum of 96W electrical appliances.

The difference between charging data cable 2a and 5a:

1, 2A charging Slow, but the conversion efficiency is higher than 5A; 5A current is larger and charging is faster. The rated current of the charger is not the actual current during operation. It will be automatically adjusted according to the load size, but the maximum rated current will not exceed the rated current.

2. The power is different. 5A supports up to 240W electrical appliances, and 2A supports up to 96W electrical appliances. The charging cable must match the power of the mobile phone, otherwise the mobile phone battery will easily be damaged.

The cost of charging cables for 3, 5A and 2A is also very different. The price of 5A and 2A charging cables is twice that of 2A, provided they are of the same brand.

Extended information:

A 5A charger can charge a 2A charger. As long as the charging voltage is both 5V, the chargers can be mixed. The size of the current only determines the charging time, and ordinary mobile phones have limits on the charging current. It doesn't matter if you use a larger charger, but it is not suitable for long-term use.

At present, most mobile phones and mobile power supplies have relatively large amounts of electricity and can withstand relatively large currents when charging, which can effectively shorten the charging time. Moreover, the output current of the charger is relatively large and can reach 5A.
