Review on 💡 Home Appliance Surge Protector & Voltage Brownout Outlet - 110V 20A, 2200 Watts by Tim Burns

Elegant product. Contrary to the previous review, I have a standard US plug with 2 outlets and both can be used with no problem if you install it on the top outlet. The minimum undervoltage is 105V, which is probably normal. However, there is no overvoltage configuration. I believe the default is 140V, which is a lot for a fridge. Since the voltage in the USA is 110V to 120V (hover), I would prefer a maximum deviation of 5% and leave the overvoltage at 130V, this is not possible with this device. The delay is also not user-configurable. It is set to 3 minutes. I prefer to leave it at zero as most fridges have compressor protection built in, even those over 15 years old. When I need it, I want it to be customizable. Finally, it says it offers surge protection, but nowhere does it mention the number of joules or protection types like LN, LG, NG, etc. I would ignore this product for any viable surge protection. Almost all such devices on the market today offer EMI protection. It does not perform EMI filtering. For a standard household compressor, the presence of such protection is important, and besides, every time the refrigerator is turned on, it introduces electromagnetic interference into the wiring of the house. But these aren't critical flaws, so I still give it 4 points. If they (the manufacturer) provided documentation on how to tweak these settings in the board, that might be great.
