Reviewers found it the smallest jump starter they tried, weighing under two pounds, with an IP65 water-resistant case. Its clamps open wide and grip well, and several reviewers called them the best they used. It started a drained 4-liter V6 three times in a row and has a boost mode for dead batteries.

It is rated for all gas engines and diesels up to 12 liters, and started a test car using boost mode. It doubles as a power bank with many ports, including 100-watt USB-C, and recharges fully in 1.4 hours. Its larger clamps are easy to use with gloves on, and its standby time is up to 24 months.

A cordless inflator that runs on its own 20-volt battery or plugs into the car's 12-volt outlet. You set a target pressure on the digital display and it shuts off when reached. It has an LED light, a USB port for charging a phone, and valve adapters. It weighs 2.6 pounds and took 4:14 minutes to reach 30 psi.

It runs from a 20-volt tool battery, the car's 12-volt socket, or a wall outlet with an added adapter. A dial sets the target pressure, and it stops automatically there. A high-pressure hose handles tires, and a high-volume hose fills and deflates air mattresses and rafts. The gauge reads within 1.5 psi.

A console-style inflator that runs on an 18-volt tool battery. It holds four pressure presets, stops at the target, rechecks after three seconds and tops up if needed. It has a 36-inch hose, a brass screw-on chuck and stored fittings for bike tires and balls. It weighs 8.7 pounds.
