1. How to install the car charger:

(1). Insert the USB power adapter into the cigarette lighter in the car (usually one in the cab and one in the trunk), insert it into the plug (as soon as it is plugged in until you hear a clicking sound), and the indicator light is on to charge. (Note that it can only be charged when the car engine is started)

(2). Using the USB cable and adapter, connect the mobile phone, MP3 or standard USB interface product to the car USB power adapter to charge it.

(3). Please check the power consumption specifications of digital products before use to avoid overloading.

2. How to use the car charger:

(1). On the car cigarette lighter, insert the USB car charger, and output DC voltage through the standard USB interface.

(2). The electronic design parameters such as voltage and current fully comply with the pda mobile phone standard and will not cause damage to your beloved machine.

(3). Connect the USB data cable to power and charge various electronic products such as MP3/MP4, mobile phones, small speakers, Bluetooth, PSP and so on.

3. Installation and use method of car charger:

The car charger is very small and practical, its installation and use is very simple, as long as the cigarette lighter socket in the car can be. The car cigarette lighter socket is shown in the figure below: when charging mobile phones, navigators and other devices, just unplug the cigarette lighter with the cigarette mark, connect the device to be charged to the car charger with the charging cable, and then plug it into the car's cigarette lighter Just the socket.

4. the use of car charger safety precautions:

(1). The vehicle cannot be charged when the vehicle is turned off (the car battery is used at this time)

(2). It is forbidden to connect and charge when the vehicle is ignited and started (to prevent the instantaneous high current from burning out the equipment when starting)

(3). Minimize charging of multiple devices at the same time, and try to avoid charging high-power devices (too much load)

5. we need to remind everyone that there are many problems that should be paid attention to in the use of car chargers.

(1). Recharging after starting Note that the device should be plugged in to charge after the engine is started. When the car is ignited, the voltage is low, which will affect the charging effect and even damage the car charger.

(2). Pay attention to the use environment. Do not use the car charger in thunderstorm weather; do not use it after washing the car. The high humidity in the car will easily cause corrosion and oxidation of components.

(3). Reduce the use of high power. Do not supply power to more than three devices at the same time to prevent damage to the device due to excessive power.

(4). Pull out the plug in time after use.

6. When purchasing a car charger, you generally need to pay attention to the following issues:

(1). Confirm the safety device: In addition to identifying the brand and not buying three no products, car owners should also know whether the selected car charger casing meets the flame retardancy standard and whether it has an overcurrent protection device. Generally, the smaller car chargers are likely to have no overcurrent protection installed, so try to avoid buying them.

(2). Choose well-known brands: car owners should try to choose products from well-known brands and regular manufacturers when purchasing car chargers. Although the price will be relatively higher, the quality will be more guaranteed.

(3). Don’t blindly pursue high current: When the current is too large or there are too many interfaces, there may be more failures and dangerous situations, so car owners should not blindly pursue high current, multiple interfaces and charging speed when purchasing a car charger. In addition, some car chargers on the market still have false voltage and current standards, so you must pay attention when purchasing and using them.

(4). Don’t buy Sanwu products: Don’t buy cheap products with too low prices, and don’t buy or use Sanwu products. Make sure that the product packaging is printed with production standards, factory name, factory address and other information.

We only use the car charger correctly, the service life of the product is longer, especially for electronic products. Therefore, for safety reasons, you must buy regular brands and buy genuine products. Poor quality products are prone to safety hazards. In addition, when using it, be sure to operate it in the correct way.
