What to know before buying

Listing details to confirm

The listing specifies horizontal-blade vents only and says round vents are incompatible. It also gives supported louver dimensions of 0.4-1.2 inch long and 0.13 inch thick. Confirm the vehicle vent matches, and retighten the clip periodically as directed. The title calls the clip metal, while the listed enclosure material is ABS, so the clip material is unconfirmed.

Customer feedback is broadly positive about installation, grip, stability and adjustability. The supplied summary says customers report that phones stay in place and that the mount fits a vent, while the listing limits fit to horizontal-blade vents. That distinction matters: favorable experiences do not establish compatibility with every vehicle vent. Aggregate ratings are mostly in the top categories, though lower ratings are also present.

Frequently asked questions

Will the HD-C78 fit any car air vent?

No. The listing specifies horizontal-blade vents and says round vents are incompatible. It also lists supported louver dimensions, so compare those with your vent before buying.

Can the phone be positioned vertically or horizontally?

The listing describes a 360° rotating and pivoting ball joint that allows switching between vertical and horizontal viewing orientations.

Can a phone charge while mounted?

The listing says space is reserved for a charging cable so it will not obstruct the phone's charging port. A charging cable is not listed as included.
