| Six Common Problems and Solutions: |
|
|
| Problem: The appliance does not work, and the converter indicator light is not lit because the battery is poor, the positive and negative terminals are connected incorrectly, or the wiring is not securely connected. |
| Suggested Solution: Check the battery, replace or inspect the battery connections based on the specific situation. The converter may be damaged and needs to be replaced or sent for warranty or inspection. Also, ensure that the cable lines and connections are tightened. |
| Problem: The appliance does not work, and the red indicator light on the converter is lit. The reason is that the rated power of the appliance exceeds the nominal power of the converter, causing overloading to be cut off, or the power of the appliance is less than the nominal power of the converter, causing the peak power to be too high, causing overloading to be cut off, or the battery power is completely discharged (the converter alarms), or the ventilation is poor, causing overheating to be cut off, or the input voltage is too high. |
| Suggested Solution: Use appliances with a power less than the rated power of the converter, or use appliances with peak power exceeding the converter's peak power. Use appliances with peak power consistent with the converter's peak power, or charge the battery, replace the battery, or turn off the converter. Allow 15 minutes for cooling, clear away items around the fan and converter, place the converter in a shaded area, reduce the load as required, restart, or check the charging system's operating status. The battery output voltage is 12V. |
| Problem: The reason for the converter output voltage being too low is that the general voltage meter used for measurement has a too small reading range. |
| Suggested Solution: Measure the output of the rectifying wave converter using a true RMS multimeter to obtain accurate data. |
| Problem: The reason why the converter can only drive small-power loads is that voltage attenuates when current passes through wires. |
| Suggested solution: reduce the length of the wire, use thicker wire. |
| 5 Questions: The reason for the short battery life is that the electrical consumption of the appliance exceeds the rated load of the converter, or the battery is poor, damaged, or not fully charged, or the current decreases when passing through the wire. |
Suggested Solution: Use a large capacity battery or replace the battery. If the charger cannot fully charge the battery, replace it with a better intelligent charger or shorten the length of the wire. Use thicker wires.

Section Two: Safety Issues to Be Aware of During Use
|
| 1. It is best to use it fixedly, and remember not to use it on the dashboard: Inverters are generally quite heavy, and if used on the dashboard, they are easily thrown up during emergency braking, which could injure people or break the windshield. Please be careful. |
| 2. Do not suddenly turn on the ignition while using the inverter in a parked state: The ignition of a car can generate a very high shock voltage, which is easy to break the MOSFET devices of the inverter and cause damage to the inverter. The correct approach is to turn off the inverter before turning on the ignition. Wait until the car is on fire, and then continue to use the inverter. |
| 3. Do not touch the output directly: Although the power is very small, it can still cause an electric shock, hehe. |
| 4. When using a high-power inverter, for appliances over 150W, the inverter must use battery clamp wires to directly draw power from the battery: the car's ashtray fuse is usually 15A, which is suitable for appliances with a rated power of less than 150W. For appliances over 150W, it is necessary to use battery clamp wires to directly draw power from the battery, otherwise it will burn out the car's wiring and fuses. |
| 5. Under normal use, if the input fuse of the inverter burns out, it is best not to replace it yourself: 99% of the time, the input fuse burns out because the input MOSFET is blown. If you replace the fuse and continue to use it, it is easy to burn out the car's fuse. The correct approach is to contact the sales representative or the after-sales service of the manufacturer. |
| After going through all this, I believe everyone should have a better understanding of the safety of inverters. Finally, I would like to say, for peace of mind and to avoid any trouble, please make sure to purchase products from legitimate manufacturers with after-sales service guarantees. Do not buy or use products without any identification, as these can lead to problems when it comes to quality issues. Who will you blame if something goes wrong? By then, it will be too late to regret. |
| Dongxing Digital's Inverter Series: A FQA Dialogue on the Integration of Cars and Laptop Computers |
| Cars are undoubtedly a mobile office, and laptop computers are an indispensable office tool. |
| Therefore, the life and work of modern people are inseparable from cars and laptops. |
However, the problem is that laptop computers require power supply to work, and the typical spare battery for a laptop can only last up to 6 hours. Moreover, under battery power, some devices in the laptop are typically not turned on by default, such as wireless high-fidelity devices and WiFi network cards. If these devices are not turned on, it is essentially the same as declaring the laptop useless.
| How can cars charge computers? |
| Can I use the car's cigarette lighter to power a laptop? (Note: This is a regular transformer, not an inverter.) |
| The answer may disappoint you, no can do~! |
| The voltage in a car varies with the capacity of the battery. |
| A 100A battery shows very little variation in voltage and current when the car is running. |
| A 40A or 60A will result in significant voltage fluctuations. |
| 100A batteries are usually used in freight trucks, so I doubt you would work on a truck. |
| This fluctuation poses little harm to electrical devices in cars, but it is quite normal for a laptop to overheat or even catch fire when connected to an external power source, as laptops operate at their maximum power when supplied by an external power supply. |
| In other words, even if you just honk the horn, it could potentially damage the machine. |
| So, how can I use a laptop computer in a car? Is there really no way? |
| Certainly, there is a way, and that is the special inverter for cars. |
| This product can reverse the 12V, 24V, or 48V DC power source into 220V AC power, so you can connect your laptop power supply to the inverter to use normally. |
