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 Scoony Taker

I've only had this recently but have used it to inflate Segway tires a few times. It's definitely better than bringing it to the store. gas station or with a hand pump. It provides more than enough amps for my portable electric tire pump. There's only one reason I didn't give it 5 stars. The car connector was a bit tricky to assemble and had to play with it a bit, but when it's done it works fine. I definitely recommend this product.
