I bought it few months before after listening my uncles comment on this inverter. But, I am not satisfied with this product.
The reasons are
( 1) it produces sound while charging. Actually I like to live in a calm and quite place. Its sound is terrible.
( 2) It produces heat in oitput the wire.
( 3) Its back up capacity is too poor.
My friend, I must recommend not to buy this product. I think luminous inverter is far better than this one.
