Ring Heavy Duty Air Compressor review
Ring Heavy Duty Professional Air Compressor 12V
By Tom Calder
Key specs
The maker's figures.
- Power source
- 12V, 280W
- Max pressure
- 100 psi max
- Inflation speed
- 13" tyre to 35 psi in under 90 seconds
- Extras
- 7m coiled airline, 3 nozzle adaptors
A properly built compressor rather than a glovebox toy — metal body, brass nozzle and a 7m airline that reaches every tyre from one battery connection. The trade-off is that it clips straight to the battery terminals, so you'll need bonnet access rather than a quick plug into the 12V socket.
- Best for
- Drivers, van/4x4 owners and caravanners who want a robust compressor that lives in the boot for real use, not just an emergency top-up
- Skip it if
- You want a lightweight inflator for occasional top-ups via the 12V socket without opening the bonnet

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Metal body and brass nozzle feel built to last, not disposable
- Quick on the tyre size Ring tested it on — 35psi in under 90 seconds for a 13" tyre (allow longer on bigger 17-18" wheels)
- 7m airline plus battery-clamp power means you can reach all four corners of a van or 4x4 without moving the vehicle
Worth knowing
- Battery-clamp only connection means popping the bonnet, not a quick socket plug-in
- Bulkier and heavier than pocket-sized inflators, so it's a boot item, not a glovebox one

Who shouldn't buy this
If you want a lightweight inflator for occasional top-ups via the 12V socket without opening the bonnet, a compact socket-plug inflator will suit you better than this one.
