Want to know the difference between Charger 1A and 2A?

March 21, 2023

The difference between chargers 1A and 2A is that 1A has a low current, while 2A has a high current. A high current charger charges faster than a low current charger. Here is the technical staff of (YHY)YingHuiYuan power adapter manufacturer for you to talk about the difference between them:

Chargers 1A and 2A are universal and, in theory, can charge a phone as long as the port is plugged in. The charger of 2A represents its maximum output charging current 2A, and the maximum output charging current of 1A is 1A, and the output current of the charger is related to the impedance of the battery it charges, rather than the charger of 2A must only output current 2A. The higher the current, the hotter the phone and charger will be, which will feel slightly hot.

Charging a low-current phone with a high-current charger will have almost no effect and will not charge faster. Small current can charge a large current mobile phone, but the speed is slow, the charger will also be in the load state for a long time, causing the charger to overheat, easy to cause the charger aging speed, is not recommended to often use.

Shenzhen YHY professional mobile phone charger manufacturers, 10 years focus on charger product research and development, provide mobile phone charger, battery charger, electric car charger, car charger, power adapter production.

The output current of the charger is actually determined by the state of the load. For example, the output of a charger can reach 20A, but if the charging logic control of the mobile phone in the hand of the consumer is only 2A, then the actual charging current is only 2A, the charging speed will not be affected. A good mobile phone charger will be designed inside the circuit protection, once the current is too large when the trigger protection mechanism, to protect the safety of consumers.

It is recommended to use the original charger if you can use the original charger. If you have another charger, it is not recommended to use the charger below 1A. Mobile phone charger purchase to choose large manufacturers, 3C certified products. Avoid buying off-brand and copycat products from irregular channels.
