Tire inflator with inflation timer

1. A portable inflation device for inflating an object, the portable inflation device comprising:

an air pump for delivering pressurized air and having

an elongated air hose, and

an inflation nozzle that is configured to connect to the object;

a user interface configured to receive a target pressure and a unit of pressure in which to display a current pressure and the target pressure;

a first inflation indicator configured to display

an estimated remaining time,

the target pressure,

the current pressure of the object,

a field that graphically represents the estimated remaining time, and

the unit of pressure in which the target pressure and the current pressure are displayed;

a second inflation indicator configured to display the estimated remaining time; and

a control device wirelessly coupled to the user interface and the second inflation indicator, the control device configured to

control operation of the air pump, the control device including a sensor that detects the current pressure,

receive, via wireless communication, the target pressure from the user interface,

convert the target pressure and the current pressure to the unit of pressure in which to display the current pressure and the target pressure,

calculate the estimated remaining time until the current pressure is within a predetermined margin of the target pressure,

send the estimated remaining time to the first inflation indicator; and

send, via wireless communication, the estimated remaining time to the second inflation indicator.

2. The portable inflation device of claim 1 , wherein the control device couples with a mobile communication device.

3. The portable inflation device of claim 2 , wherein the control device is configured to send, via wireless communication, a notification to the second inflation indicator and the mobile communication device when the current pressure is within the predetermined margin of the target pressure, and wherein the second inflation indicator is configured to display an indication that inflation is complete.

4. The portable inflation device of claim 1 , wherein the control device couples with an onboard computer of a vehicle.

5. The portable inflation device of claim 1 , wherein the control device is configured to shut off the air pump when the current pressure is within the predetermined margin of the target pressure.

6. The portable inflation device of claim 1 , wherein the second inflation indicator further displays the current pressure and the target pressure.

7. The portable inflation device of claim 6 , wherein the second inflation indicator is configured to display the current pressure and target pressure in the selected unit of measurement.

8. The portable inflation device of claim 1 , wherein the second inflation indicator includes a field configured to graphically indicate inflation progress.

9. The portable inflation device of claim 1 , further including a power cord for connecting the portable inflation device to a power source, wherein the second inflation indicator is positioned on an end of the cord.

10. The portable inflation device of claim 1 , wherein the control device is configured to activate a symbol on the second inflation indicator when the current pressure is within the predetermined margin of the target pressure.

11. The portable inflation device of claim 1 , wherein the control device is configured to activate a vibration device on the second inflation indicator when the current pressure is within the predetermined margin of the target pressure.

12. The portable inflation device of claim 1 , wherein the control device is configured to activate a sound-making device on the second inflation indicator when the current pressure is within the predetermined margin of the target pressure.

13. The portable inflation device of claim 1 , wherein the user interface includes an RFID reader or a QR code reader configured to read an RFID tag or QR code that has the target pressure for the object embedded thereon.
