NOCO Boost GB40
The jump starter

NOCO Boost GB40

Small enough for the glovebox, starts most gas cars on its own, and charges a phone while you wait for anyone else to turn up. Bought once, forgotten until the one morning it matters.

Buy it for
Anyone who has ever needed a stranger with jump leads.
Skip it if
You drive a large diesel or a truck. Look at the bigger GB-series packs.

What actually matters when buying a jump starter

  1. Ignore the peak amps figure; it is marketing. Look at the engine size the maker rates it for, gas and diesel separately.
  2. Spark-proof clamps and reverse-polarity protection, so connecting it the wrong way round in the dark does no harm.
  3. How well it holds its charge. A lithium pack should still start the car after months in the glovebox; top it up every few months anyway.
  4. Cold performance. The morning you need it is usually a cold one.
