My current charger is broken, but I found another charger which kind of fits, but im suspicious if it will harm my laptops battery in the long run, what commands can I run or what can I look at to see if a new type of charger is harming a laptops battery? as this isnt usb-c or anything really official.

Hadn't heard about those, but a quick search shows those aren't standard barrel connectors, although they look similar. The Dell connectors have a third pin for data. Normal barrel connectors only have two pins.

For the OP, that means that if your laptop is a Dell from the period where they were doing this, you need a specialized cable and charger intended specifically for Dells.

    Given the context that we were talking about laptop chargers rather than generic power bricks, I think it’s fair to consider standard laptop power supplies. (HP has the same connectors even though their protocol is different, and I’m not familiar with other brands but I expect they are much the same).

    Now you got me curious, so I got up and checked:

    2008 HP laptop: Appears to be a standard barrel with no center pin. (Also has yellow trim and is in-line with the cord.)

    Circa 2013 HP laptop: Has the connector with the center pin. (Larger than the barrel on the 2008 model, and at right angles to the cord)

    So it's era-dependent (and I used that 2008 model too long). TIL.
