Handpicked Reviews
Editorial picks, compared and dated.
By Marcus ReedMarcus Reed · Roadside Gear EditorPublished in September 2026A flat battery or a slow puncture is the most common way a car strands you. Both problems have the same fix: keep a lithium jump starter and a way to add air in the trunk, and check them twice a year. We compared six current roadside tools - four jump starters, two of them with built-in compressors, and two tire gauges - on peak amps, air pressure ratings, cable length and how they behave in cold weather.

Buyer's Guide
Peak amps are marketing, cranking amps are reality
Packaging leads with 'peak' amps measured in a lab instant. What starts a cold engine is sustained cranking current, so compare that figure and stay well above your engine size.
Compressor built in - or separate?
A combined unit saves trunk space, but the compressor adds bulk and cost. If you already own an inflator, a compact jump pack is lighter and cheaper.
Cold weather is the real test
Lithium packs lose output in freezing temperatures. Look for a unit rated well above your needs, and store it inside the car rather than in an unheated garage.
Safety features that matter
Reverse-polarity protection, spark-proof clamps and a manual override are the differences between a tool and a hazard. Check for all three.
Tire pressure discipline
A good gauge beats guessing: check monthly and before long trips, and set pressure cold. Digital gauges are faster and easier to read than pencil types.
FAQ
Match the pack to your engine - a small petrol car needs far less than a diesel or a V6. Buy comfortably above the rating rather than at it.
Not if it has reverse-polarity protection and you follow the sequence. Read the manual once before you need it.
They are fine for topping up tires. For repeated use on large tires, a dedicated inflator is faster.
Every three to six months, and before winter. A flat jump pack is the classic roadside disappointment.
