The Difference Between 2A Phone Charger and 1A Phone Charger

There are basically three kinds of charger plugs, the Android phone plug is a Micro USB interface and a Type-C interface, and the Apple mobile phone is a Lightning interface.

For most smartphones, the charger’s output specification is 5V/1A, or 5V/2A. When charging a 5V/1A phone, the 5V/2A charger and the 5V/1A phone charger have the same current, but the 5V/0.6A charger current is slightly lower and the charger is overloaded. So as long as it is a regular charger, such as the original phone charger, it can be compatible.

Nowadays, fast charging technology is developing very fast. Many mobile phones have increased the voltage and current in order to speed up the charging speed, which may be 9V/2A, or 5V/4.5A. Regular chargers are based on the output voltage/current of the mobile phone, that is, according to the power output of the mobile phone. Therefore, using a fast charge charger will not cause damage to the phone.

Whether you’re charging your mobile phone or charging your phone, everyone wants a quick way to charge. At present, there are many types of charging treasures on the market, and many mobile power supplies use two USB output interfaces or smart charging design, which can support 5V/1A, 5V/2A or 5V/2.1A output parameters. Can be compatible with different digital devices.

Which charging speed is fast?

We used the 5V/1A adapter and the 5V/2.1A adapter to charge the iPhone 6 separately, and used a thermal imager to record the temperature of the two adapters after one hour of operation.

Through the actual charging test, we get: when using the 5V/1A adapter, the phone is fully charged once, it takes 2 hours 07 minutes, the maximum temperature of the adapter is 66 ° C.

When using the 5V/2.1A adapter, charge the phone with a single charge, which takes 2 hours and 01 minutes, and the maximum temperature of the adapter is 60 °C.

The temperature of the adapter is also generated under its working condition. Now the charging time and temperature of the two adapters are relatively close, which means that the charging time of the 2.1A charger and the 1A charger is very close when charging the mobile phone.

Summary: Whether it is charging treasure or mobile phone, tablet computer and other equipment, the internal use of charging protection device, and we also passed a series of tests to prove that when charging mobile power or mobile phones, 2A charging is not necessarily more than 1A charging faster.
