### ⭐⭐⭐⭐⭐ It adapted heater to wall charger perfect.
*by P***. on December 12, 2025*

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.
