Review on 🚗 Versatile Portable Car Tire Inflator - 12V with Large LED Light, Auto Shut Off Digital Air Pump for Car Tires, Bicycle & More by Derek Dolla

This is pump #2 as the first had problems straight away (overheating, excessively noisy and rattling motor). Sent it back for a replacement. The second pump works as described. No pump will be quiet, but it's quieter than other pumps I've used. It doesn't pump air as fast as others say when your tire is 10psi. I noticed that the amount of air is off by 1psi. When I put my tire on the air pump at 40psi, my car PSI monitor reads 41psi. So heal it, set the pump to 5 psi below your target psi. In my case I need 40psi, so I set the pump to 35.5psi to reach the target. Just remember this little trick and you're done. Will keep this review in mind for long term use.
