Hello, thank you for your inquiry. Your Coleman QuickPump&trade; 12V is designed to run on a 12V DC cigarette lighter socket, which can supply up to 10 amps (120 watts) or more. However, a USB port (even USB-C) typically provides: USB-A: 5V at 1&ndash;2.4A = 5&ndash;12 watts USB-C (PD): Up to 20V at 5A = 100 watts (but only if properly negotiated with a device that supports it). Your USB converter is likely only giving 5V and far too little current for what the pump needs. That&rsquo;s why the pump runs slowly, or it doesn&rsquo;t build enough pressure to inflate anything properly. Solution: Buy a portable 12V power station or jump starter with a 12V cigarette lighter socket. These are rechargeable and made to power 12V devices like your pump. : Use a Car with a Working 12V Outlet If available, a car with a functioning 12V cigarette lighter socket and inflate from there. Do not use USB adapters to power the pump. They can't deliver enough current. Do not use AC wall USB chargers unless you have a 12V output converter with 10A capacity (which is rare) If you have any more questions, please contact us through our official Coleman website form https://www.coleman.com/supportShow?cfid=contact-us or via live chat, and we will be happy to assist you. Thank you, and please stay safe! Coleman Consumer Care
