The Difference Is in the Details
Not all car chargers are built the same. Here's why drivers are switching.

Still Have a Question?
Will it fit my car?
Yes. It plugs into any standard 12V or 24V cigarette-lighter socket — cars, trucks, SUVs, and RVs.
How do the retractable cables work?
Gently pull a cable to the length you need. When you unplug, it glides back into the housing on its own. No winding, no tangle.
What does the voltage display actually do?
It shows your car battery's live voltage. A healthy reading sits around 12.4–12.7V at rest. If it starts reading low, that's your early heads-up that the battery or alternator may need attention — before it leaves you stranded.
How many devices can it charge at once?
Up to four, thanks to the two built-in cables plus the extra USB ports, sharing 120W of total output.
Is the starlight distracting while driving?
No — it's a soft, ambient glow across the roofliner, designed to add atmosphere without glare. One tap turns it off entirely.
