An aerosol generating device comprising: a heating element configured to heat an aerosol generating material; a battery configured to supply power to the heating element and receive power from an external device; an output unit; and a processor configured to control the output unit to output a notification indicating whether the aerosol generating device is usable, within a predetermined time period after power supply from the battery to the heating element is discontinued, or within the predetermined time period after the battery is charged to a predetermined level. ### Claim at position 2 (depends on 1, 2) Claim 2. The aerosol generating device of claim 1, further comprising a storage configured to accommodate the aerosol generating material, wherein the notification indicates that a remaining amount of the aerosol generating material is less than an amount corresponding to one smoking act consisting of a predetermined number of puffs. ### Claim at position 3 (depends on 2, 3) Claim 3. The aerosol generating device of claim 2, wherein the amount corresponding to the one smoking act is differently determined according to an environment in which a user smokes. ### Claim at position 4 (depends on 1, 4) Claim 4. The aerosol generating device of claim 1, wherein the notification indicates that remaining power of the battery is less than an amount of power that corresponds to one smoking act consisting of a predetermined number of puffs. ### Claim at position 5 (depends on 4, 5) Claim 5. The aerosol generating device of claim 4, wherein the amount of power that corresponds to the one smoking act is differently determined according to an environment in which a user smokes. ### Claim at position 6 (depends on 1, 6) Claim 6. The aerosol generating device of claim 1, wherein the notification indicates a remaining number of an aerosol generating product, and the aerosol generating product is configured to deliver an aerosol generated from the aerosol generating material to user’s mouth such that the aerosol entrains at least one component included in the aerosol generating product. ### Claim at position 7 (depends on 1, 7) Claim 7. The aerosol generating device of claim 1, wherein the predetermined level is an amount of power that corresponds to one smoking act consisting of a predetermined number of puffs. ### Claim at position 8 (depends on 1, 8) Claim 8. The aerosol generating device of claim 1, wherein the output unit comprises at least one of a display, a light source, a motor, and a speaker. ### Claim at position 9 (depends on 1, 9) Claim 9. The aerosol generating device of claim 1, wherein the notification comprises at least one of an image, light emission, vibration, and sound. ### Claim at position 10 (depends on 9, 10) Claim 10. The aerosol generating device of claim 9, wherein the image, the light emission, the vibration, or the sound of the notification are changed as time passes. ### Claim at position 11 (depends on 1, 11) Claim 11. The aerosol generating device of claim 1, wherein the processor is configured to discontinue operation of the aerosol generating device when a predetermined amount of time has passed after the notification is output. ### Claim at position 12 (depends on 12) Claim 12. A method of controlling an aerosol generating device, the method comprising: identifying a first time point when power supply from a battery to a heating element is discontinued, or a second time point the battery is charged to a predetermined level; and outputting a notification indicating whether the aerosol generating device is usable, within a predetermined time period after the first time point or the second time point. ### Claim at position 13 (depends on 12, 13) Claim 13. The method of claim 12, further comprising stopping operation of the aerosol generating device after a predetermined amount of time has passed after the notification is output. ### Claim at position 14 (depends on 12, 14) Claim 14. A computer-readable recording medium having recorded thereon a program for executing, on a computer, the method of claim 12.
