Review on 🔌 Universal AC/DC Power Supply Adapter - Transform 100-240V to 12V Cigarette Lighter Socket for Various Car Devices: Tire Air Compressor, Vacuum Cleaner & More! by Paul Varnado

I've been trying to find this product at local electronics stores but couldn't find it. So I was happy to find it on Revain. It works exactly as described. You need to make sure you choose the right size to power your air pump and this one is perfect. I no longer have to connect a pump to my car to inflate my bike tires. It came with a US and a European plug, which would be nice for international travelers. I recommend it.
