Some good ideas here, as Challenge’s 7025 model has a digital gauge which can be removed and used independently. There’s a strong handle incorporating a torch which also works independently. But between them, these extras need six AAA batteries, which will soon go flat when left in your car. Auto cut-off is a plus, yet the valve connection was tricky to fit. At 20psi it was only 0.5psi out, but it was 4psi short at 30psi.
