Travel charger:
The English name of the travel charger, Charger, usually refers to equipment that is dedicated to power storage devices. The travel charger is mainly a static current-converting device that converts alternating current with constant voltage and frequency into direct current using power electronic semiconductor components.
There are many chargers, such as battery chargers, travel chargers, car chargers and external battery chargers.
The external battery charger, also called "external battery", is developed with the popularity and rapid growth of digital products. It is defined as a large-capacity portable power source that is easy to carry. With this charger, you can supply power (power or charge) to a variety of digital products anytime, anywhere in the mobile state.
A battery charger such as a battery is mainly an electrochemical chemical device that stores chemical energy and discharges electric energy when necessary. The battery is mainly immersed in the electrolyte (dilute sulfuric acid) through the anode (PbO2) and cathode (Pb) in the lead storage battery, and generates 2V power between the two poles to realize functions such as charging and discharging, and the shape and size are different, and some are not directly Use the second time. Car charger, also known as car charger, is a mobile phone charger accessory that can be used to charge digital products anytime and anywhere with the vehicle power supply when the owner is traveling. At present, some high-end car chargers generally include two USB ports, which can charge two digital products at the same time. These products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, and four safety protection functions to ensure safe use. The car charger can also be used at home, and it can realize three-in-one multi-purpose use of car charger, direct charge and USB charge.
Precautions:
1), travel charger in the charging process of the mobile phone battery should pay attention to the output voltage of the power supply must be within the specified range, otherwise the charging function can not be achieved.
2) Keep the charger dry, as rain, moisture, and various liquids or moisture may contain minerals that can corrode electronic components and wiring.
3) Do not put it at a high temperature. High temperatures will shorten the life of electronic devices, damage batteries, and age certain plastics.
4) When purchasing a travel charger, it is best to purchase it from a manufacturer's authorized franchise store (cabinet), so that you can buy authentic original accessories. Due to the random selection, the charged appliance may not be in optimal use, and even severely affect its normal use.
