I have been using this inverter Since 4 or 5 months and I face no difficulty whatsoever this is the 850 watt inverter and I attach with 165 mhA tabular Amaron battery.
I am living in a small village so at my home the frequently light goes off at that time this innovators help me magnificently. I know the 850 volt is little less but I attached with 165 Milli ampere battery so its battery is really big and its give me the 10 hour battery backup.
Sometime I find difficulty to run multiple objects at the same time but I know the capacity of the inverter is little less so you always find this difficulty on that product if you are very highly user so please buy big inverter.
But your usage is low then this is the best product for you people and I recommended this product I highly recommended this product for you.
