Buy Car chargers manufacturers note, we all know that when the phone is used for a long time, the battery will run out of power, and when the power runs out, it will charge. What are the precautions and details for charging your phone? Shenzhen Yongletong charger small series for you: Charger 1, constant voltage charging, according to different voltage levels have different charging voltage. Therefore, only according to the size of the current to select the charger is not. For example, a battery charger charges a 5-volt battery, but can not charge a 12-volt or 6-volt battery. Trickle charge also varies from battery to battery, often referred to as floating charge current, and its size is closely related to the battery’s capacity. For example, a normal charge current for a 10,000 Mah battery may not be as high as the floating charge current for a large capacity battery. Constant current charge is the simplest overcharge form of battery, it will affect the battery life, or even damage the battery. Because there are two basic principles for maintaining batteries: Don’t overcharge and don’t use too much power. In violation of these two rules, the battery will not break immediately or its capacity may be reduced. Figure 3. Constant current charging is a charging process. The charging current remains constant and the charging voltage increases approximately linearly. Charging directly at 0.1-0.2 degrees Celsius shortens battery life, even if no other accidents occur. Therefore, this is why constant current charging begins with a constant charging current and an approximately linear increase in the charging voltage. In fact, it’s used to extend and maintain battery life.Safety Device: in addition to identifying the brand and not buying the three-no products, car owners should also know whether the car charger shell of their choice meets the fire-retardant standards, whether there is over-electricity maintenance device. Generally speaking, smaller vehicles may not receive adequate maintenance and should be avoided as far as possible. Figure 2. CHOOSE WELL-KNOWN BRANDS: when buying chargers, car owners should try to choose well-known brands and conventional manufacturers of products. Although the price will be higher, but the quality will be more assured. Figure 3. Do not blindly look for large current: When the current is too large or the interface is too large, there may be more faults and dangerous situations. Therefore, car owners in the purchase of chargers, it is best not to blindly pursue the large current, multi-interface and charging speed. In addition, some car chargers on the market still have voltage and current standard errors. We must be careful when we buy and use them. Figure 4. Don’t buy three-nil products: Don’t buy too cheap products, don’t buy three-nil products. Check the specifications, factory name and address on the package.
