An electronic cigarette (e-cigarette), or vape, [note 1] [1] is a device that simulates smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. [2]
A later-generation box mod e-cigarette. An e-cigarette is a handheld battery-powered vaporizer that simulates smoking, but without tobacco combustion. [1] Once the user inhales, the airflow activates the flow sensor, and then the heating element atomizes the liquid solution. [5]

A 2017 review found "Many e-cig users prefer to vape at high temperatures as more aerosol is generated per puff. However, applying a high voltage to a low-resistance heating coil can easily heat e-liquids to temperatures in excess of 300 °C; temperatures sufficient to pyrolyze e-liquid components." [59]
A 2017 review concluded that 80% of e-cigarette explosions occurred during battery charging, many by 3rd-party power adaptors that used inappropriately high charge rates that led to thermal runaway. Some vendors assembled e-cigarettes from incompatible parts. [99] E-cigarette device explodes in man's pocket while on bus in California. [108]
The battery slowly charges a capacitor, which is then discharged through a flashbulb to provide a high-current pulse to ignite the bulb. [2] Higher-voltage photoflash batteries were also made to fire reusable xenon electronic flash tubes, which require a high voltage, without the use of circuitry generating this voltage from low-voltage batteries.

The HP DeskJet 500, 510, 520, 500C, 550C, and 560C were all replaced by the HP DeskJet 540 (3 ppm B&W, 1.5 minutes per page color). A one-pen inkjet printer, color was optional. Also it introduced a different industrial design. HP's high-end printer line started with the HP DeskJet 1200C, introduced in 1993, offering 6 ppm B&W, and 1 ppm color.
