This is an AC adapter from iFi that achieves a noise level of 1uV or less. I purchased it new and used it in a pet-free and smoke-free environment. It works well and I think it's in good condition. 【Condition of the product】 ・Scratches: Almost none ・Operation: No problems ・Box and accessories complete ・Accessories are unused The packaging remains on the box, except for the top. The accessories are clean because they haven't been used. I believe everything is included, but please check the photos. I was using it with a Wi-Fi router, but I'm selling it because I changed the configuration of my equipment and no longer need it. (The tester in the photo is not included) It's already packed and can be shipped as early as today.
