Manufacturer description

The TESSAN Surge Protector Outlet Extender turns a single wall socket into a 7-device charging station: 4 AC outlets plus 3 USB ports, including one USB-C. It is a straightforward fix for the bathroom counter, dorm desk, or office nook where one duplex receptacle never covers everything you own. The two USB-A ports deliver 2.4A and the USB-C port delivers 3A, and both types detect the connected device to set an optimal charging speed, so a phone, tablet, and earbuds can top up while the AC outlets stay free for a lamp and a laptop brick. Surge protection is rated to a 1875W maximum…

TESSAN's home & kitchen lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
