Good quality surge protector.
Size: 6.5 FT, Color: Black
It's great to have a search protector that has this much versatility. One of the spots that this is mostly needed is around the TV area. With the need to plug in TVs, DVD players, surround sound theater system equipment, Xbox and PS5's, wifi router etc. This thing has more than enough plug spaces then you can throw it at a single time. The east of having all these connecting ports available in one compact place is a big win. It also eliminates running unnecessary wires being that old the plugs you need to plug in will have it available socket. This search protector also has a very premium feel due to quality materials. Another great feature that it has is that you can hang it or drill it to a wall due in large part to its available pre drilled holes. Also the way that the sockets are aligned are perfect to plug different types of plugs with enough space in between. There is enough separation to make different types of plugs fit snuggly.

The Ultimate Command Center for My Workbench
Size: 6.5 FT, Color: Black
I finally ditched the old, flimsy power strip on my workbench and mounted this DEPOW 28-in-1 Surge Protector on the wall behind it. Honestly? It was the best move I’ve made for my workspace in years. Here is why this thing is a beast for anyone with a hobby or work bench: Insane Outlet Capacity: With 22 AC outlets, I no longer have to play "musical chairs" with my power tools. I can keep my chargers and bench tools plugged in simultaneously without running out of room. The Modern Tech Solution: It feels like every new gadget uses USB-A or USB-C these days. Having 6 dedicated USB ports (including 3 USB-C) built right in means I can charge my phone, tablets, and lights without using up my precious AC space with bulky "bricks." Pro Mounting & Design: Mounting it on the wall cleared up so much clutter on the bench surface. The 6.5ft flat plug cord made it easy to reach the wall outlet even with the bench pushed flush against it. Peace of Mind: With 2100 Joules of surge protection, I don’t have to worry about my expensive electronics or power tools getting fried during a storm. The Bottom Line: This isn't just an extension cord; it’s a full-on power hub. If you have a mix of high-power tools and modern USB-charged gear, "this baby" truly does it all. Highly recommended for gamers, DIYers, or anyone with a home office!
