Mainly depends on the charging plug, but the quality of the charging line can also affect the charging speed.
Choose the right charging plug for the devices . for example , the charging speed will very slow when you use the iPhone charger plug to charge the iPad as the power of the plug is insufficient . Most of the time, the 1A ac adapter is smaller than the 2A ac adapter, so we can usually judge the current by the size of the adapter.
So, suggest using the original charger plug .
The current of the charger output is determined by the load .
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 hands of consumers is only 2A, then the charging speed will be basically unaffected within the actual charging current of 2A. A good mobile Phone Charger will be designed inside the circuit protection, once the current is too large when the timely trigger protection mechanism, to protect consumer safety.
The 1A and 2A chargers are versatile and, in theory, can be recharged 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, while the charger's output current is related to the impedance of its charging battery, rather than 2A charger must only output current of 2A. The higher the current, the higher the temperature of the phone and charger.
Charging a low-current phone with a high-current charger will have little affect and will not speed up the charging process. Small current can be used to charge the mobile phone with large current, but the speed is slow, and the charger will be under load for a long time, resulting in overheating of the charger, which is likely to accelerate the aging speed of the charger. Frequent use is not recommended.
It is recommended to use the original charger if you can use the original charger, and it is not recommended to use the charger below 1A if another charger is equipped. Mobile phone charger purchase to choose large manufacturers, there are 3C certified products. Avoid buying miscellaneous brands and cottage products from informal channels.
