Why It Works
- PTC heating technology solves the slow warm-up problem by delivering instant, focused warmth directly to you.

Trade-offs

This little black unit promises to be a rapid defroster and a personal warmer, and after testing it, I can see why it’s climbing the charts.

LILITUAN Portable 12V Car Heater
LILITUAN Portable 12V Car Heater: 200W power, ABS and heat-resistant plastic construction, universal 12V plug, 360-degree rotatable bracket.
Benefits
This little unit punches above its weight. The 200W heating element warms up a standard car cabin noticeably in just a few minutes, making those first chilly drives much more bearable.

Drawbacks
