Review on SW MOTECH Legend Gear Motorcycle Tankbag by Scott Chen

This is exactly what I was looking for. Not too big but enough for phone, keys, wallet, gloves, garage door opener, charger with free space. There is a rain cover if you need one. Slot for connecting the charging cable to the phone. The magnets hold great, but there's also a strap system if you need extra security. I can put it on the tank without turning off the gas to refuel. Seems to be of solid workmanship, but time will tell.
