• Your USB charger is more powerful than Apollo 11’s computer

    The USB-C charger used to keep your laptop going is more powerful than the guidance computers used on board the Apollo 11, which helped the first astronauts get to the moon.

    Apple software engineer Forrest Heller compared the specs for three USB-C chargers, the Google Pixel 18-Watt Charger, Huawei 40-Watt SuperCharge, and the Anker PowerPort Atom PD 2.

    By comparing their Random Access Memory (RAM) and the Apollo Guidance Computer, he found that the Anker charger has eight kilobytes RAM compared to the Apollo computer, meanwhile, has four kilobytes of RAM.

    When comparing more aspects such as the RAM, clock speed, program storage space, and a few other components, he concluded that today’s USB-C chargers are more or less 563 times faster than the Apollo computer.

    Heller said that since there were reportedly four computers on the Apollo 11, it would take 4 Anker PowerPort Atom PD 2 USB-C chargers to get to the moon, with very specific caveats.

    Despite acknowledging the power of these chargers, Heller admitted there would be limitations to using them to power the spacecraft. One shortfall was that Heller said he did not know the peripherals on the Apollo 11 and therefore was not sure how much power was needed by the guidance computer to support these.

    While our computer chargers may not actually be able to send a spacecraft back to the moon, acknowledging how far we’ve come since our first ‘giant leap’ is impressive.
