A portable jump starter is a battery pack with clamps that starts a car with a dead battery, without a second car or jumper cables. Many now include an air compressor, so one box also fixes a soft tire. Winter is when batteries fail most, so it's worth having one in the trunk. Here are AstroAI's and Buture's jump starters compared on power and engine size, plus the best cordless and 12V tire inflators, with today's prices and codes.

Ways to pay less on a jump starter
FAQ
What size jump starter do I need?
Match it to your engine: check the engine size each brand lists. Small cars are fine with about 2000-3000A; trucks, SUVs and diesels need more. AstroAI rates its 4000A A30 and S8 Ultra for up to 10.0L gas and 8.0L diesel.
Is a jump starter with an air compressor worth it?
If you want one box in the trunk for both a dead battery and a soft tire, yes. Models like the AstroAI A30 and Buture Beta09 include a compressor.
What is the best tire inflator?
For most drivers, a cordless inflator with a digital gauge and auto shut-off, such as the AstroAI L7S or Garvee's 150 PSI model. If you'd rather never charge it, a 12V model like AstroAI's plugs into the car.
What PSI should I inflate my car tires to?
Use the pressure on the sticker in your driver's door jamb, often around 30 to 35 PSI, not the maximum printed on the tire.
