Eskating cyclist, gamer and enjoyer of anime. Probably an artist. Also I code sometimes, pretty much just to mod titanfall 2 tho.

Introverted, yet I enjoy discussion to a fault.

  • For the power matter, you don’t. The device being charged, the charger, and cable does.

    If you mean what is the maximum wattage that will actually be used, that should be the maximum possible between the charger, cable, and device. So look at their specs. Whichever has the lowest maximum, is what the others will match.

    USB PD defines a protocol for the device and charger to determine max safe power. If the cable is replacable (not attached to the charger), it must be rated for PD and be able to tell the charger it can handle more than just the usual 5 volts at 2 amps.

    USB PD chargers only output the maximum safe amount of power. That’s why I can use my 65W steamdeck charger to charge my phone if I want to. It just outputs normal USB charger power if the device on the other end can’t verify it can handle more.

    It’s also why my SteamDeck charger is what I use to fast charge my phone, because it can actually talk to it using the USB PD protocol to request the voltage and amps it needs to fast charge.






  • They’ve lasted quite well.

    But it’s apparently one of the things the designers want to do better with future rovers.

    The design was meant to be light-weight while providing good traction on the martian surface, but it has turned out more fragile than they’d hoped. All six wheels on Curiosity are quite damaged.

    The wheels on Perseverance are still aluminium, but instead of the zig-zag tread, the large gaps of flat metal that have been getting punctured, were done away with. The wheels on Percy instead have a dense pattern of wavy tread.
