If you don't need a pressure gauge, and you'd rather just have something that can inflate your tires on its own, consider springing for a portable air compressor instead. You'll have a higher out of pocket cost, but considering that the tool we shared above doesn't have an inflating function built-in, you won't be able to use it to add air to your tires without a separate tool. If you do have an air compressor around, however, the Tacklife Digital Tire Gauge should do the trick just fine.
