Refuel Smart Propane Tank Gauge

Propane tank’s out of fuel? Party’s over. Don’t get caught off guard: gear up with Quirky’s Refuel instead. This system relies on a scale that fits underneath standard propane tanks and that’s wired to a plastic puck equipped with LEDs and Bluetooth to monitor your tank’s contents – just tap the sensor or launch Quirky’s Wink app to get a reading. It’s also Wi-Fi compatible, letting you check on fuel from anywhere, runs on four AA batteries, and sports magnets to stick to a handy spot on your grill.
