What Is A Travel Charger:
The English name of travel charger is Charger, which usually refers to a device that provides energy for power storage devices. The travel charger is mainly a static converter device that uses power electronic semiconductor components to convert alternating current with a fixed voltage and frequency into direct current.
With the rapid development of the global economy, more and more people go out for travel, and more and more portable electronic products, such as mobile phones, digital cameras, mp4, GPS, travel chargers, etc., all use batteries , But the random batteries of these devices seem to be unable to meet the normal use time of the device because of the low battery capacity, but the emergence of travel chargers has solved this problem. The charger has a wide range of application prospects in the electric occasions where the battery is used as the working power source or the backup power source.
Types of travel chargers:
There are many phone chargers, such as battery chargers, travel chargers, car chargers and external battery chargers, etc.
External battery charger, also called "external battery", mobile power charger is developed with the popularity and rapid growth of digital products, and its definition is a convenient and easy-to-carry large-capacity portable power supply. With this charger, you can provide electrical energy (power supply or charging) for a variety of digital products anytime and anywhere in the mobile state.
Battery chargers such as accumulators are mainly electrochemical devices that store chemical energy and release electrical energy when necessary. The battery mainly uses the anode (PbO2) and cathode (Pb) in the lead storage battery to be immersed in the electrolyte (dilute sulfuric acid), and 2V electricity is generated between the two poles to realize charging and discharging functions. The shape and size of the battery are different, and some cannot be directly The use of the second time.
Car charger, also known as car charger, is a mobile phone charger accessory for car owners to use car power to charge digital products anytime and anywhere when traveling. Some high-end car chargers generally include 2 USB ports, which can charge two digital products at the same time. Such products generally have overload protection, short-circuit protection, high-voltage input protection, high-temperature protection, and four-fold safety protection functions to ensure safe use. The car charger can be used in the car and can also be used for home use, realizing the three-in-one multi-function use of car charging, direct charging and USB charging
