Rubin 301 Auxiliary Car Heater Reviews

I popped the Rubin 301 into my car’s 12 V outlet and was blown away by how fast it warmed the cabin. Installation is a snap—just plug it in and you’re good to go. It puts out steady heat on chilly mornings without sucking the battery dry, so you get extra warmth with no trade‑offs. The unit feels solid, the controls are intuitive, and the heat output is surprisingly strong for its size. I took it on a week‑long road trip; the battery held up fine even with the heater running. Bottom line: a cheap, plug‑and‑play solution that adds real comfort on frosty drives.
