Review on 🚗 H Helteko Air Compressor Tire Inflator DC 12V: Portable Car Tire Pump with LED Light, Long Power Cord, Auto Shut Off, Carrying Case - Ideal Electric Air Pump for Car Tires, Bicycles, and More! by Alex Jones

So far so good! I haven't used it long enough to know how well it works, but it inflated the RV tire to 76 pounds, although it would cycle on and off, which stopped when I pushed the power button all the way down. Will update in future if I use it more. The one I received above was damaged in shipping as it was completely out of service after that use. They immediately sent a replacement and I have used it twice to inflate 6 truck tires to 80lbs, 4 car tires to 35lbs and 4 bike tires to 40lbs. The device shutdown is within 2 pounds of any of my tire gauges. He works like a champ and Helteko has the best customer service I have experienced in years. Thank you Emma!
