Review on Cordless Tire Inflator Air Compressor, Battery Powered Car Tire Pump, Portable Handheld Air Pump With 12V Car Power Adapter Digital Pressure Gauge For Cars Motorcycles, Gray by Chris Ostby

Acquired for the specific purpose of getting rid of annoying "low pressure" lights on the dashboard because weather in the South is finicky, fickle, and annoying.Battery has a nice life indicator on it, and there's a 12v adapter for emergencies, though as with most pumps that have a 12v cord, better hope it's long enough! At any rate, got all four tires from 28 to 32 in less than 5 minutes. It takes about 15 seconds from showing the initial pressure reading before it will let you bump the trigger to kick it on and will shut off a bit AFTER it hits the set number (I guess to account for bleed-off that might happen when you disconnect the chuck).It's plastic. Don't toss it about or let it ride around in a truck toolbox. Best kept in your utility room of choice. I don't 100% like the valve. Feels like the pin that holds the chuck lever in place could fall out if handled too roughly. But if one factors these things in, it's a good tool. If it can juice up a tire another 4psi fairly quickly, I imagine inflatable toys, basketballs, etc will be a breeze.
