The Safety Capability

The BMK 200W inverter comes with built-in smart chip, which detects the connected devices. After the successful device detection, it will start supplying 6.2A output current to charge the connected devices.

According to BMK, the 110V inverter is fully safe because it is very protective against all the electrical causes. Therefore, the inverter is protective to under & over voltage, short circuit, undercharging and overload. To fight with all these problems, the unit has 15A built-in fuse, which automatically protects not only the unit itself, but also the connected devices.

 Advanced LCD Display

The advanced LCD of this car inverter shows battery voltage and USB current. Thus, the LCD display not only shows relevant notifications, but also informs you for the safety related things. By knowing the battery voltage and output current, you will be able to know if everything is fine or not.

Complaint – please be careful because an Amazon customer received the inverter with damaged LCD. If similar thing happens, please contact the manufacturer.

Additionally, the inverter comes with a built-in switch, which is good for controlling the car electric plug for the safety purposes.

Smart Cooling Fan

The integrated cooling fan in this BMK inverter runs noiselessly. The cooling fan is programmed to run automatically. The fan runs faster when the inverter gets warmer. Well, the manufacturer calls it smart cooling fan but I don’t think so. To me, it is a normal cooling fan because most of the inverters have cooling fan with the same conditions.

Like several other inverters on the market, this BMK 200W inverter also features an LED indicator. The main task of this LED indicator is to show the working status. It indicates with two colors such as green and red. Green color means operation and red color means shutdown.
