Fitment Notes

  • Always match OEM reference number(s) and vehicle details before ordering. Verify VIN/engine.

Professional Fitment Required: Electronic, electrical, and electromechanical components require correct identification before installation. Compare the new unit to the removed unit and verify mounting orientation, terminal or connector type, pin count or terminal arrangement, voltage rating, polarity, and any pulley or bracket configuration where applicable. Incorrect installation, polarity reversal, water or moisture ingress, improper connector seating, or mismatched specifications can damage the component, related ECU systems, or cause persistent fault codes. Installation by a qualified, VAT-registered workshop with appropriate diagnostic equipment is recommended.

Returns Notice: Once an electronic, electrical, or electromechanical component has been fitted, plugged in, energised, or shows signs of installation, returns are limited to manufacturing defect only. Confirm part compatibility before opening sealed packaging.

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!

Fantastic power strip with tons of outlets!
Size: 6.5 FT, Color: Black
This surge protector power strip is amazing! With 22 AC outlets and 6 USB ports including USB-C, it's incredibly versatile for all my devices. The flat plug makes it easy to fit behind furniture and the 6.5-foot cord gives plenty of reach. The 1875W capacity handles everything with ease!
