A compact hot air gun comprising a body, an air blowing pump, an air outlet tube, and a heating coil. The air blowing pump is disposed in the body. The air outlet tube has an end connected to the air blowing pump and another end extending beyond the body. The heating coil is disposed in the another end of the air outlet tube opposite to the air blowing pump. The compact hot air gun can generate an ignition effect by using hot air through the above structure.

A portable low voltage material combustion system and methods of making and using the system including a non-transitory computer readable medium containing a program code executable to deliver an output voltage or an output current from the mobile computing device to an igniter which converts the output voltage or the output current into heat sufficient to ignite a primer composition to generate flame spread in associated combustible materials.

A portable grill with a battery power system includes a primary direct-current power source and a secondary direct-current power source. The primary power source can connect onto the outside of the grill via a clip. The secondary power source, which can be disposed within the grill so as not to be exposed to outside elements, can continue to power the grill when the user removes and/or replaces the primary power source during the operation of the grill. A user feedback system can remotely alert the user with information regarding the time or power remaining in the primary power source.

Pellet grills including a control system that implements, manages, and/or controls various ignition-based protocols and/or processes are disclosed. An example pellet grill includes a cooking chamber, a burn pot, an ignitor, and a controller. The ignitor extends into the burn pot and is configured to ignite pellet fuel located within the burn pot. The controller is configured to command the ignitor to activate during a first duration. The controller is further configured to determine, following expiration of the first duration, whether a temperature of the cooking chamber has reached a threshold temperature. The controller is further configured, in response to determining that the temperature has not reached the threshold temperature, to command the ignitor to activate during a second duration.

A smoking pen device is disclosed. An example smoking pen device includes a stem having an inlet end and an outlet end. The example smoking pen device also includes a first end piece connecting to the inlet end of the stem, the first end piece configured to receive a coil heated by electric current to combust a smoking product in the first end piece. The example smoking pen device also includes a second end piece on the outlet end of the stem. A gas or vapor from combustion of the smoking product flows from the first end piece through the stem and out of the second end piece. In an example, the second end piece is a mouth piece. In another example, the second end piece is configured to fit into an inlet port on a water pipe.
