A fan of the classic 1993 game “Doom” managed to run the game on the built-in screen of a phone charger from the company “Anker,” according to a report by the tech site “Tom’s Hardware.” Thanks to the specifications of the charger’s unit, Aaron Christoffel was able to run the game on the “Anker Prime Charger,” which features an internal chip with 16 MB of storage and 8 MB of RAM, as well as a 2.26-inch screen with a resolution of 480×200 pixels. The unit’s processor runs at 150 MHz and is an ARM type with an integrated graphics card, surpassing the original device’s specs required to run the game, which had a 33 MHz frequency. The Anker Prime Charger is the company’s most powerful charger unit, offering additional features not necessary for running the game, such as six USB ports and 250 watts of power delivery.

Christoffel controlled the game using the charger’s control piece, which can be rotated and pressed to click, but the device cannot play game sounds due to the lack of an external sound unit. Christoffel said the game runs better than expected thanks to the device’s specs and the low requirements needed to run the game originally. The classic “Doom” game was one of the first games released for computers and was very popular at its release and for a long time. Many contemporary games have adopted its gameplay style. The game has also been run on many devices that usually do not support such games but have internal processors and screens, from calculators to cameras and some computer software.
