Compatibility with My Car

Power Source and Battery Life
Some adapters plug into the cigarette lighter or USB port, while others have built-in rechargeable batteries. I preferred one powered through the car’s USB port so I didn’t have to worry about charging it separately. Battery life is crucial if you opt for a rechargeable model.
Additional Features I Found Useful
