About Product Overview

This Thermocube outlet converter turns a single wall outlet into two, giving you a quick way to run an extra cord without rewiring anything. It's built for indoor use on standard 120-volt circuits and handles up to 1800 watts at 15 amps, which covers most household electronics and small appliances.

The 2-pole, 3-wire design is non-polarized, so it's a straightforward, no-frills solution for adding outlet capacity where you need it - at a desk, behind an entertainment center, or in a workshop.

  • 15 amps, 120 volts, 1800 watts

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
