beware of this brand KISAE. The product doesn't even power a 190 watt device, a complete junk. low current Indicator labels at 12.4V undervoltage E 0 error. So this product is not worth the money. Better look for another brand. The return shipping fee also need to be paid by me, which is not customer friendly. Not being able to return the item for free I decided to keep the item and opened it up and surprisingly the item was made in 2012 and appears to be refurbished similar to a product returned by a previous customer. I noticed a defect in one of the two transformers (it smells like melted plastic), which is the reason for the very low output power. So one star is too many for this product but I can't take it off.
