Who Needs This Adapter?
- Homeowners running a portable generator during a power outage — power two circuits at once
- Contractors and tradespeople splitting generator power across multiple tools on the jobsite
- Campers and tailgaters connecting two appliances to a single 30 amp generator outlet
- Anyone needing to run a standard 15 or 20 amp plug off a 30 amp L14-30 generator outlet
- Emergency preparedness — power a refrigerator and a sump pump simultaneously
Primelight® Indicator Lights — Know Your Power is On
Each of the two 20 amp receptacles features a built-in Primelight® power indicator light. No more guessing whether your generator is delivering power — the light confirms it instantly. A small detail that makes a big difference when you’re working in the dark or managing an outage.
Extreme-Condition STOW Cord — Built for Real Work
The 10-gauge STOW jacket is rated from -58°F to +221°F and resists oil, moisture, and ozone. Whether it’s a January ice storm or a summer jobsite, this cord stays flexible and reliable. The 4-blade L14-30P twist-to-lock plug seats firmly in your generator outlet and won’t vibrate loose under load.
Versatile Outlets — Works with 15 & 20 Amp Plugs
The two NEMA 5-20R T-slot receptacles accept both standard 15 amp grounded plugs and 20 amp T-blade plugs — so you’re not limited to specialty equipment. Run a refrigerator on one side and a power tool on the other, or connect two standard household extension cords to distribute power wherever you need it.
