These are legit. High quality. Work as expected. Review: It adapted heater to wall charger perfect. - Worked as intended. Using it for a heater in my garage gym and I have an outlet for car charging, so I wanted to use the outlet since I don't have an EV. House is still intact as of writing this review. Cable hasn't over heated. Length works for me as the cable on the heater is long enough. ## Features - Max 240V 30 Amp, cannot transform to 120V - 14-50P Ground connects 6-30R Ground - 14-50P Hots connect 6-30R Hots - 14-50P Neutral is empty(Open) - Made of High Quality Copper Wire - ETL Listed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P93FXDW | | Amperage | 30 Amps | | Best Sellers Rank | #151,806 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #518 in Electrical Adapters | | Brand | ONETAK | | Color | 14-50P/6-30R | | Connector Gender | Male-to-Female | | Customer Reviews | 4.8 out of 5 stars 125 Reviews | | Ethernet Cable Category | Cat 3 | | Input Current | 30 Amps | | Manufacturer | JUMO TRADING LLC | | Model Number | 37c708ef-e904-42a3-9e20-51906680e0fb | | Number Of Conductors | 6 | | Number of Outlets | 1 | | Plug Format | Type B | | Plug Type | Type B | | Power Cord Prong Count | 7 | | UL Listed | Yes | | UPC | 799695357925 | | Unit Count | 1.0 Count | | Voltage | 120 Volts | | Wattage | 7200 watts | ## Product Details - **Brand:** ONETAK - **Color:** 14-50P/6-30R - **Connector Gender:** Male-to-Female - **Plug Format:** Type B - **Voltage:** 120 Volts ## Images ![ONETAK NEMA 14-50P to 6-30R ETL Listed 240V 50 Amp 4 Prong Male Plug to 30 Amp 3 Prong Female Outlet Receptacle Generator Dryer Welder Welding Dryer Power Cord Adapter - Image 1](https://m.media-amazon.com/images/I/81ERGdKXIJL.jpg) ![ONETAK NEMA 14-50P to 6-30R ETL Listed 240V 50 Amp 4 Prong Male Plug to 30 Amp 3 Prong Female Outlet Receptacle Generator Dryer Welder Welding Dryer Power Cord Adapter - Image 2](https://m.media-amazon.com/images/I/91s3Eisqc0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly correct. *by E***T on March 1, 2026* Super.
