1, the voltage of small cars is 12 volts, large trucks are 24 volts, you can buy a 12 volt car charger.
2, Volkswagen Lavida plus car charger to buy 2 ampere to 5 ampere suitable. Car charger to facilitate the daily electricity needs of car users, practical is very strong, the common car charger is basically between 2a and 5a, and the more suitable car chargerThe a numbers are 4a, 2a, and 8a.
3, battery problem: If you can charge normally after replacing with another good battery, then it is your battery problem.
4, the car charger can not be directly connected to the battery, the car charger center is positive, the iron sheet on both sides is negative, the car charger can be directly inserted in the car's cigarette lighter jack, the specific steps are as follows: open the door on the side of the cab. Press the brake pedal. Press the one-touch start button to start the engine. The dashboard lights up to show that the engine has started.
5, to put the millet handThen press the charge button to charge.
This is directly inserted in the cigarette lighter socket inside the charging head, to modify can only add a cigarette lighter one drag two sockets. Features: Versatility, portability, fashion, security. With the development of the automobile industry, car chargers are widely used, showing the characteristics of versatility, portability and fashion.
The 12v power interface of the car has no fixed insertion method, and can be directly inserted, regardless of positive or negative. Cigarette lighter socket can be connected to: air pump (car special air pump), car special vacuum cleaner, various car special lights, inverters (can be converted to 24V36V110V220V power supply, easy to use electricity when going out).
It is not recommended to connect the power supply in this way, although it is 12 volts, but because the output power of the battery is limited, in order to protect the battery, it is reasonably distributed by the manufacturer, and has various load protection functions, and has reasonable protective measures. The load carried by the car charger is also strictly limited, and you can see the manufacturer's instructions.
No, unless someone is temporarily on duty for a short time to charge (note that the battery shell temperature shall not exceed 55 degrees, the total charging time shall not exceed two hours, if the battery is highTemperature, can be charged for ten minutes, rest for five minutes and then charge so operation). Mainly the car charger charging current is the lowest level of 10a, to more than 70ah car battery charging.
The battery is generally outside and the charger is in the car, if the direct connection will be more troublesome, if it is a small power then it is recommended to buy a branch plug online, or consider finding a firewire from the car.
1, look at the charging system, the online introduction of this usb-a port is 5V/3A or 9V/2A. The general tachograph should only be 5V1A, so it can not be charged, and the voltage or current is too large.
2, driving recorder can use millet car charger fast charging version power supply, fast charging version can provide current that meets the fast charging standard, but it does not mean that it has been powered by this current, and the final power supply current size depends on the electrical equipmentThe size of the current.
3, the driving recorder can be powered by USB. Dashcam is very simple, very low current. As long as it is a 5V power port can be used, and the standard voltage of USB is 5V, so there is no problem. However, the driving recorder can be powered by USB, there are some limitations, because the USB interface of some models will have a certain current peak and trough when the car starts. This situation is highly likely to damage the dashcam. And the USB interface is not suitable for long-term use.
4, because some driving recorder he is USB interface, need to use USB converterConversion to power supply, now there are a lot of dashboards, already support type c power supply, if necessary, you can directly buy Type-C interface dashboards. The car tachograph interface is type c, it is recommended to buy the type c interface tachograph, if it is USB interface, it is recommended to buy the USB interface tachograph.
5, because the USB can not provide power after the turn off, can not meet the working needs of the driving recorder 24 hours. Most dashcams can be powered via USB. The power supply for the dashcam is usually connected to the cigarette lightOn the device, the plug of the cigarette lighter is basically just an adapter, and the adapter is mostly a USB interface. Therefore, the driving recorder can be plugged into the cigarette lighter, or it can be directly plugged into any USB interface on the car with USB.
1, Yes, but more troublesome. Xiao Ai can adapt to the Internet normally, so when the car has a wireless network and 12V power supply orIn the case of cigarette lighter, you can use small love students on the car. Small love speaker car cigarette lighter method, cut off the power adapter, buy a cigarette lighter plug, and then connect the line, you can use, and then open a hot spot on the phone.
2, small love speaker in the car to use a simple version: you can buy a millet car inverter, the small love speaker plugged in the above and then connected to the mobile phone hot wifi, placed in the center of the drawer on the line. Disassembly version: Cut off the power adapter, buy a cigarette lighter plug, and connect the cable to it, and then it is ready to use, and turn on a hot spot on the phone.
3, small love speaker car cigarette lighter method, cut off the power adapter, buy a cigarette lighter plug, and then connect the line, you can use, the phone and open a hot spot on the line. The voltage output of that adapter is 12V, and the cigarette lighter voltage is also 12V, so it can be used.
