My dear friends today i shall share my experience with you about su kam shiny 900 va 12v pure sine wave inverter. Friends in the last summer i purchased this inverter at a price of 7800 rupees. Friends when i used this inverter then i came to know its disadvantages. Friends this inverter is of very poor quality. Its battery life is very less. Its charging speed is also very slow. Within 4 months its battery has damaged. Then i purchased one more battery from market. So friends i was very disappointed to purchase that inverter.
