Short answer: Mains and 12 V are complementary ways to power a tyre inflator, not two different answers to the vehicle's required pressure. The ATJ-8366 is documented for AC 110-230 V and DC 12 V, and its listed 2.8 m lead and 63 cm hose help with reach planning. Use the mains mode where the socket and plug arrangement are verified, and the 12 V mode where the vehicle socket is suitable. Read the handbook or placard for the target pressure every time. ATJ-8366 dual-power AC/DC car tyre inflator is the documented product used for this comparison.

The tyre target does not change with the socket
| Mode | Use case | Verification |
|---|---|---|
| Mains | Garage or driveway | Plug and socket |
| 12 V | Vehicle-side use | Vehicle socket and fuse guidance |
| Either | Pressure check | Handbook or placard target |
Reach determines convenience
