3 bikes (6 tires) inflated to 65psi on first use with no problems. The device stops exactly at the pressure you set. The hose gets very hot during the process, but everything worked fine. I only partially charged the device before the second use. At that point he was only able to inflate 1 tire and on every second attempt the code "ol" was displayed, which is not in the brochure. I tried again to charge the device in the car for 1 hour, the result is the same. Over the next week I fully charged the device at home (2 hours) and it inflated all 6 tires with no problems. The size and price seem very good.
