$128.23 (was $179) · ★ 4.6 · 17,701 reviews
Tire inflators rank among the most essential car gadgets you should carry on every road trip; without one, a flat tire in a remote area could leave you stranded for hours. The DeWalt Tire Inflator stands out among gadget car accessories because it can be powered by a 20-volt max battery, a 12-volt DC connection, or a standard 110-volt AC connection can power it. This versatility means you’re never left without a power source. It delivers a maximum pressure of 80 pounds per square inch, and you can dial in your desired target pressure via the onboard control buttons.
