An inverter is an electronic device that converts low voltage (12, 24, 48 volts, etc.) direct current into alternating current. In our daily life, the 110V alternating current is usually rectified into a direct current, while the inverter has the opposite effect, so it is called "inverter". We are in a “mobile” era where there are full of mobile offices, mobile communication, mobile leisure, mobile entertainment, etc. So we need power not only the DC power but also the AC power to juice up electronic devices for mobile fun no matter where we are. The inverter is to meet our needs.


How to choose

From the perspective of mainstream inverters, car inverters are mainly divided into two types, pure sine wave inverters, and modified sine wave inverters. Both inverters have the necessity of choice, depending on the needs of everyone. To choose an inverter that meets your needs, you must first understand what a pure sine wave inverter and a modified sine wave inverter are.


Modified Sine Wave Inverter

Compared with the square wave, the waveform of the output voltage of the modified sine wave inverter has a significant improvement, and the content of the higher harmonics is also reduced. The conventional modified sine wave inverter is generated by the stepwise superposition of the wave voltage of square sine wave. But this way will lead to many problems including a complicated control circuit, more power switch tubes used for the superimposed lines, and larger volume and weight of the inverter. In recent years, with the rapid development of power electronics technology, PWM pulse width modulation has been widely used to generate correction wave output. At present, the modified wave inverter has been widely used in user systems in remote areas, because these user systems are not very demanding on the quality of power consumption, and the modified inverter is suitable for carrying electrical resistance.


Modified sine wave inverters can be applied to mobile phones, notebook computers, televisions, video cameras, CD players, various chargers, car refrigerators, game consoles, DVD players, and power tools. It is also widely used as a backup power source for tourism or field operations, and can also solve the problem of power consumption in remote and power-deficient areas. It can be used as a supporting inverter power source for wind power generation and solar photovoltaic projects, and can also be used as a backup power source for industrial and mining enterprises. So, only one modified sine wave inverter can meet almost all our basic needs.


Pure Sine Wave Inverter

Pure sine wave inverter delivers good output waveforms with very low distortion that are almost the same as the main grid. In fact, an excellent sine wave inverter provides higher AC power than the grid. The pure sine wave inverter has low interference to the radio and communication equipment and precision equipment, low noise, strong load, and can meet all AC load applications. Compared with the modified sine wave inverter, the pure sine wave inverter has a more complicated circuit, higher skill requirement on-chip control, and maintenance, and is more expensive. If you have valuable or precise devices, you may need a pure sine wave inverter because it provides high-quality, high-efficiency and stable sine wave output, and has high-frequency technology. It can drive any kind of devices including TV, washing machine, air conditioner, water heaters, liquid crystal displays, refrigerators, etc. without any noise or damages to your devices.


BESTEK 300W Power Inverter

BESTEK is committed to the field of car power inverters for years and has now the leading inverter brand in the US. As the most popular inverters, BESTEK 300 inverter also has a pure sine wave model and a modified sine wave model.


BESTEK Modified Sine Wave Inverter

Charging Outlet:

BESTEK 300W modified sine wave inverter is the most popular in the US market. It provides 300 Watts continuous DC to AC power and 700 Watts instantaneous power and has 2 smart USB ports and 2 AC outlets that can meet your basic charging requirement. This inverter is compactly designed with iPhone-sized, ideal for use on vacations, work trips, and camping. 24-inch cigarette lighter plug makes the power inverter compatible with almost any vehicle and convenient for anyone in the car to use the power supply.
