Product Detail: 

When buying a good car power inverter 12v to 220v pure sine wave inverter 3000 watt with charger , how should we choose? 
1. Select a metal-cased pure sine wave inverter: The vehicle-mounted inverter is relatively easy to generate heat due to its high power. If the internal heat cannot be dissipated in time, it will affect the life of the components at light level, and cause fire in severe cases. On the one hand, the metal casing has good heat dissipation characteristics, and on the other hand, it also avoids the risk of fire. 
2. For products with the same power and similar volumes, the heavier ones are preferred: the heavier weight of the product means that the outer casing is thicker, which is conducive to heat dissipation, and at the same time, it also means that the internal transformer has a large power and can drive high-power loads for a long time. 
3. Perfect protection function: A good car power inverter walmart should have perfect protection function, which can protect your car and power supply under various conditions, and should also have sound and light alarm function to remind you deal with the situation in a timely manner. Generally, the protection functions that should be provided are input under-voltage protection, over-voltage protection, over-temperature protection, output overload protection, and output short-circuit protection. 
4. Conversion efficiency: Conversion efficiency is a very important indicator of the inverter. The higher the inverter efficiency, the longer the battery is used, and the less the inverter heats up. Generally, it should reach more than 90%. 
5. Pay attention to the form of the output socket: it is necessary to be able to use the two-phase and three-phase plugs of the national standard.
