At home, dragging out an air compressor just to inflate a ball or tire seems like overkill. On the road, that's not even an option. This Hoto Tools inflator is both portable and powerful enough to handle most jobs. It has five modes for common use cases, a screen to show the desired pressure, and an auto-stop feature that prevents overinflation. The built-in battery can inflate 2+ car tires per charge — or more for smaller jobs — and recharges via USB-C, and the unit comes with four common adapters, conveniently placed inside the included carry bag.
