Dongguan Golden Field Industrial Co.,Ltd. is a Chinese company that is not well known in the USA. According to the Golden Field web site the company claims to be the largest provider of power supplies in China. However, it does not appear that Golden Field is a manufacturer of power supplies. Instead their power supplies are made for them by Huntkey, Sunpro, and possibly CWT.
I could not find competent, independent, technical reviews of their power supplies.
