If you need to leave to power supply plugged in an powering a device in your home when it is not attended, I suggest using a UL listed or CE listed device. I just hate to have my sleeping family's safety depending on the design skills of a entrepreneur who is selling knock-off power supplies on eBay - the entire design would be based on cost optimization with no concern for safety of the end user and no fear that the end user will file lawsuit if property is damaged or people are injured.
Insurance companies may not be too happy to cover damages caused by non-UL listed devices that you import from eBay purchases.
