The Winter Car Kit

Cold saps batteries. Snow strands cars.

Cold-weather driving gear for the two things winter does: kills weak batteries and turns light snow into a stuck car.

The problem it solves

Cold weather is when a marginal battery finally quits, and a dusting of snow is enough to spin your tires on a slope. Two problems, a handful of items that solve them.

NOCO Boost GB40 1000A UltraSafe Lithium Jump Starter

The default best-overall. Trusted for honest (not inflated) amp ratings, UltraSafe spark-proof + reverse-polarity protection, and a genuinely pocketable size — the unit everything else is compared against.

Common mistakes
  • Trusting a marginal battery through the cold. Winter is when a weak battery finally quits — carry the jump starter and keep it charged, because cold drains it faster.
  • Flooring it when stuck. Wheelspin polishes ice into glass; ease onto the traction mats instead of spinning the tires.
  • Expecting full power from a freezing-cold pack. Lithium loses capacity in deep cold — keep it charged and, before a big trip, bring it inside overnight.
  • Having no warmth plan. If you're stranded and the engine won't run, heat is the real emergency — blankets aren't optional in winter.
  • Burying the traction mats under everything. If they're at the bottom of the trunk when you're stuck, they can't help you.
Skip for now
  • A bag of rock salt or sand — traction mats work better, don't corrode your trunk, and won't dump grit everywhere.
  • A full-size snow shovel if space is tight — a compact folding shovel is enough to free a tire.
  • The 2000A HD jump starter for a small gas car — the GB40 handles it; the HD is for diesels and big engines in deep cold.
  • A box of chemical hand-warmers as your heat plan — mylar blankets hold body heat far longer for the space.
  • A luxury 'winter survival kit' — half of it is packaging; buy the few items that actually free a car and keep you warm.
