We’re on the cusp of Black Friday, and while TVs and laptop deals get all the glory, practical gadgets are already on sale too. Fanttik’s X8 portable tire inflator is down to $69.99 ($40 off), an all-time low price at Amazon. Fanttik’s deal is only available for Amazon Prime subscribers.

The X8 is a battery-powered tire inflator for bicycles, motorcycles, and cars. It’s powerful enough to fill a 26.3-inch medium-sized car tire in under a minute, and its LCD screen displays the tire’s current pressure in realtime. Fanttik says the X8’s battery lasts up to 40 minutes, and can continuously fill 16 tires without having to cool down. You can operate the tire inflator manually, or use one of its presets to automate the process. Fanttik includes a car charger and case with the X8 for easy storage.
