Quick answer
A complete winter car kit covers five needs. Jump power (a lithium jump starter or jumper cables). Tire air (a cordless inflator and a gauge). Snow and ice clearing (a long snow brush and a folding shovel). Getting unstuck (a recovery strap). Staying safe and warm (emergency blankets and a window-break/seatbelt-cutter tool). Add water, snacks, gloves and a phone charger.
Getting stuck on a cold road is uncomfortable at best and dangerous at worst. A good winter kit fits in a single trunk bin. Most of it costs less than one tow.
Quick comparison (specs from manufacturer/Amazon listings; no prices shown)

- Jump starter (or jumper cables if you're often near other cars)
- Cordless tire inflator
- Tire pressure gauge, because cold weather lowers tire pressure
Snow, ice and traction

- Folding snow shovel
- Recovery tow strap (use rated recovery points only)
- A bag of sand or kitty litter for traction (any store)
Warmth and safety
- Emergency Mylar blankets, plus a wool blanket if you have room
- Window-break and seatbelt-cutter tool, kept within reach of the driver, not in the trunk
- Gloves, hat, hand warmers
- Flashlight or headlamp (many jump starters include one)
- Phone charging cable (many jump starters work as a power bank)
- Water and high-calorie snacks
- First-aid kit

Stay with the vehicle unless help is visible nearby.
Keep the exhaust pipe clear of snow if you run the engine for heat. A blocked exhaust can push carbon monoxide into the cabin.
Run the engine in short intervals and crack a window slightly.
Make the car visible: hazard lights, and a bright cloth on the antenna or window.
FAQ
What should be in a winter car emergency kit?
Jump power, a tire inflator and gauge, a snow brush and shovel, a recovery strap, emergency blankets, an escape tool, plus water, snacks, gloves and a phone charger.
Is a jump starter better than jumper cables?
A jump starter doesn't need a second car, which matters on a quiet road. Cables never need charging. Many drivers carry both.
Where should I keep the window-breaker tool?
Within the driver's reach, such as the door pocket or center console, not in the trunk.
Should I store a lithium jump starter in a freezing car?
Lithium packs lose power when very cold. If you can, bring it inside overnight in deep cold, or keep it in the cabin rather than the trunk.
