12V 24V LED Digital Voltmeter Dual USB Power Socket Panel

Car charger refers to the conventional car battery (car 12V, truck 24V) powered car charger, widely used in a variety of portable, handheld equipment lithium battery charging field.
Such as: mobile phone, PDA, GPS, etc.; The vehicle charger should not only consider the actual demand of lithium battery charging (constant voltage CV, constant current CC, overvoltage protection OVP), but also take into account the harsh environment of the vehicle battery (transient spike voltage, system switching noise interference, EMI, etc.). Therefore, the power management IC selected in the car charging scheme must meet the following requirements: high voltage resistance, high efficiency, high reliability, low frequency (conducive to EMI design) switching power chip. features
Versatility, portability, fashion, security
With the development of automobile industry, car chargers are widely used, showing the characteristics of versatility, portability and fashion.
Versatility: the car charger is equipped with American standard, British standard, Austrian standard and European standard four AC adapter; The car charge, direct charge and USB charge are integrated to meet the charging under different conditions; Dual USB output port, you can charge multiple electronic products. This product is also the world's first charger for charging iPad. It takes about 4 hours to charge the iPad, and you can take the iPad for a ride.
Portability: Portability is a major trend in the development of today's electronic products. The unique folding car charge design is adopted to concentrate the volume of the product to 6.9×5.6×3.1cm, which is extremely convenient to carry around.
Fashion: For the owners of this high-end consumer group, the fashion of car chargers is also paid attention to by manufacturers. Generally using ABS material and the piano paint process, not only fashion and exquisite, feel is also very good.
Safety: The product has passed CCC, UL, FCC, CE and other international safety performance tests, and has the insurance company's guarantee, strong protection of performance safety and consumer rights and interests.
application
Car charger is to facilitate the owners to use the car charging source anytime and anywhere for digital product charging accessories. Some high-end car chargers generally include two USB ports, which can charge two digital products at the same time. This kind of products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, quadruple safety protection function, to ensure safe use. Car charger in the car at the same time, also can be used for home, to achieve car charging, direct charging, USB charging three in-one multifunctional purposes. Car charger is to facilitate the use of car power supply anytime and anywhere for digital product charging accessories, for you to save the cost of batteries. This kind of product generally has overload protection, short circuit protection, high voltage input protection, high temperature protection, quadruple safety protection function, to ensure that you can use safely. The car output voltage is 12V, the truck is 24V, the general general car charger (12V) is most suitable for the car, if it is other models need to choose the corresponding voltage standard. Many car chargers can already achieve the standard of 12V-24V, that is, all models are applicable.
2, to understand the car charger automatic protection function
Whether the car charger has the functions of over-voltage, over-current, overheating, and short-circuit protection, the shell is the best use of ABS flame retardant environmental protection material, not only can prevent external combustion and beautiful, hand touch without fingerprinting.
3. Pay attention to the voltage and current
When choosing a car charger, pay attention to the voltage and current of supporting devices, such as 5V/1A for iphone, 5V/2A for tablet computers and mobile power supplies. If you charge your phone and tablet at the same time, the total current of the car charger should be at least 3A or above. Otherwise, the charging speed will not only decrease significantly, but also overheat and even damage the device.
