The charging head is compact but powerful.

Note that you will need a car charger capable of outputting at least 9V/2.25A to get the full 15W output from this Qi2 wireless charger. A cheap but good option is this 2-pack for only $10, or of you want a high-power car charger that could charge your MacBook Pro, go for this more expensive option

The Qi2 wireless charging standard enables full 15W charging speeds from non-Apple MagSafe chargers, allowing you the convenience of magnetic charging without the frustration of slow speeds. 

The ESR Qi2 15W MagSafe car charger features a Qi2-certified charging head combined with a strong magnetic ring to securely hold your iPhone in place, regardless of road conditions.

This charger offers two mounting options: a highly effective vent clamp and an adhesive mount that uses high-quality 3M adhesive for a secure dashboard attachment. I've tested both methods and found them reliable.

This wireless charger has impressed me so much that it has now replaced my older one -- an earlier ESR charger, which served me well for over a year.

ZDNET's buying advice

The ESR Qi2 15W MagSafe car charger is as close to perfect as wireless car chargers get. The charger itself is sturdy and well made, the magnets hold the iPhone in place securely, and the two options for mounting -- vent or adhesive -- give this a great deal of flexibility. And for under $40, it's an absolute steal.
