The chargers of the mobile phone of the charger manufacturer have a flat head and a round head.

What are their names? Flat-headed ones are usually called "micro chargers".

MicroUSB is a portable version of the USB2.0 standard, which is smaller than the MiniUSB interface used by some mobile phones. Micro-USB is the next-generation specification of Mini-USB. The formulation is complete.

The round head is called "type-c charger".

The USB interface has three different appearance interfaces, namely Type-A, Type-B, and Type-c. Type-C has a much smaller volume than Type-A and Type-B, and is the latest USB interface shape standard. In addition, Type-C is an epoch-making interface type that can be applied to both PCs (master devices) and external devices (slave devices, such as mobile phones).

On February 18, the GSM Association and 17 mobile operators and manufacturers announced that they will establish a unified mobile phone charger connection standard around the world. Unified connection to standard mobile phone chargers.

The above standard plan uses Micro-USB as the universal charging interface, and saves 50% of the energy consumption during charging. Different from the unified interface standard that has been implemented in China, this standard also unifies the interface for connecting the mobile phone to the charger.

What does charger mean?

A charger is a tool used to charge electronic products.

There are many chargers, such as lead-acid battery chargers, valve-regulated sealed lead-acid battery testing and monitoring, nickel-cadmium battery chargers, nickel-metal hydride battery chargers, lithium-ion battery chargers, lithium-ion battery chargers for portable electronic devices, Lithium-ion battery protection circuit charger, electric vehicle battery charger, car charger, etc.

Proper and reasonable charging is good for extending battery life, while improper charging will have a great impact on battery life. Lithium batteries are basically packaged separately according to each product and are not compatible with each other. Therefore, each product also provides its own charging equipment, which is not compatible with each other. Just follow the respective instructions when using it.

How the charger works

All mobile phone chargers are actually composed of a stable power supply (mainly regulated power supply, providing stable working voltage and sufficient current) plus necessary control circuits such as constant current, voltage limiting, time limiting, and overshoot.

The output parameters marked on the original charger (referring to the line charger): such as output and output 5.9V/, refer to the relevant parameters of the internal regulated power supply. For example, the output 4.4V can be used for 4.5V devices, and the 5.9V can be used for 6V devices.
