best noco prime day dealsAs winter weather approaches, sudden cold snaps can wreak havoc on vehicle batteries and tire pressures. Cold temperatures slow down the chemical reactions inside battery cells right when engines need maximum power to turn over cold oil. At the same time, ambient pressure drops cause tire air to contract, reducing tire pressure by roughly 1 to 2 PSI for every 10-degree dip in temperature.To keep you prepared, Ohio-based power technology company NOCO-a family-owned brand founded in 1914-is offering discounts up to 20% off during Amazon Prime Day (October 6–7).Here are the top NOCO deals on portable jump starters, smart battery chargers, and air compressors to stock in your trunk or garage before temperatures plummet:NOCO Boost GB40 12V 1000A UltraSafe Portable Lithium Jump StarterBuy NowKey Specs: 1,000 Amps, up to 20 jump starts per charge, rated for up to 6.0L gas / 3.0L diesel enginesWhy You Want It: The ideal entry-level lifesaver for daily commuters.
