Charger How To Buy

Estar Industrial Group Co.,Ltd | Updated: Sep 08, 2017

Charger is the use of high-frequency power technology, the use of advanced intelligent dynamic adjustment of charging technology. Chargers are widely used in various fields, especially in the field of life is widely used in mobile phones, cameras and other common appliances. Charger is the use of power electronic semiconductor devices, the voltage and frequency of fixed alternating current into a direct current DC converter device. In the battery for the work of power or standby power supply occasions, the charger has a wide range of applications.

There are many such as lead-acid battery charger, VRLA battery testing and monitoring, nickel-cadmium battery charger, nickel-metal hydride battery charger, lithium-ion battery charger, portable electronic equipment lithium-ion battery charger, Lithium-ion battery protection circuit multi-function charger, electric car battery charger, car charger and so on.

All mobile phone chargers are actually composed of a stable power supply (mainly regulated power supply, to provide a stable operating voltage and sufficient current) plus the necessary constant current, limiting voltage, time limit and other control circuit.

Original charger (finger line charge) marked on the output parameters: such as the output 4.4V / 1A, the output 5.9V / 400mA ... ... refers to the internal regulator power supply related parameters. Understand the truth, you will know a (good quality) mobile phone charger is easy to change into a good quality power supply! Such as the output of 4.4V 4.5V can be used with the equipment, 5.9V can be used to 6V equipment.

The widespread use of smart phones, then how to extend the use of mobile devices, play its maximum function? Mobile power (charging treasure) came into being! The Many people are more or less hands have several mobile power, then, how to correctly buy mobile power?

1. Look at batteries. 18650 and polymer batteries, preferred polymer batteries, polymer batteries, lighter, do not explode, 18650, heavy, and may explode.

2. See conversion rate. A power supply can give the phone a few times depends on the circuit board conversion rate and cell capacity, cell capacity, circuit board conversion rate of the same number of low charge will be less, anti-cell capacity is small, power plate conversion rate, The same number of times.

3. Look at product charge management: the majority of mobile power is the use of ordinary linear charge management, this charge management is too old to keep up with the times, and large-capacity rechargeable charge is full of electricity to charge more than 15-20 hours full. Now the smart phone capacity is used within the internal pulse charge management, pulse charge management with a large charging current, low temperature, long battery life and other multiple advantages.
