Developer Finds USB-C Chargers Are 563 Times Faster than Apollo 11's Computer

Could your USB-C charger fly a spaceship? Apparently, it has the power to do so.

Apollo 11's Computer, A USB-C Floating in Space12

We think about our smartphones being more powerful than past's intelligent computers more often than not, however, it seems that this new finding might surprise you even further. Apple developer Forrest Heller argues that even a modern USB-C charger has more processing power than the guidance computer that took Apollo 11 to the Moon in 1969.

You might be thinking that it is comparing apples to pears, however, we can actually simplify the objects into their very core and draw from there.


Forrest Heller listed all the basic specs in his blog post and compared the processing power of the battery chargers of the Google Pixel 14W, Huawei 40W SuperCharge, AnkerPowerPort Atom PD 2 with the guidance computer developed by NASA more than fifty years ago.

Apparently, the Apollo 11 Moon landing guidance computer had a clock speed of just 1.024 MHz compared to 48 MHz for the Anker PowerPort Atom PD 2 that Heller used for comparison. 

It has around 4KB of RAM compared with Anker's charger's 8KB, and 72KB of storage compared to 128KB of flash memory. Not only it can store 1.78 times more instructions, but it also has twice the amount of RAM.

All of this combined, show that the modern charger is 563 times faster than the Apollo 11 computer!

However, don't let the power disparity fool you. According to Heller, you'd need four chargers to replace the four different computers on board Apollo 11.

Also, could your charger take you to the moon and back? It seems highly unlikely, however, knowing that it has the power to do so, puts things into a much different perspective.
