What specs are needed for USB-C charger unit to charge Swift SF314-51?

Hello,

Currently, I've tried using 90W (split 80W and 10W) and 60W USB-C charger units. Neither of them work. However, an old Apple Macbook charger (61W) works (charging with it as I type). I've even purchased an Apple compatible USB-C charger with the exact same specs (61W - output:20.3V-3A(USB PD) or 9V-3A(USB PD) or 5.2V-2.4A(USB PD)) but that doesn't work.

The issue isn't enough output since dedicated 80W should have been more than enough.

I thought it might have been because it needed something very specific (61W) as it charges with the official Apple charger. But since it doesn't work with the aftermarket 61W charger, I am stumped.

Anyone know what could set the OEM Macbook Pro charger apart? Or maybe someone who has purchased a USB-C charger that works with their Swift3 be able to suggest something?

I've replaced the AC component twice now (charges fine once replaced initially but eventually gets loose again and fails to charge - is this a possible flaw in the design?) and the only reliable means of charging has been through the USB-C port.

Thanks

Wattage shouldn't matter as long as the charger is rated for 45W or higher, since the actual load is determined by the charged device, not by the charger. You likely do need to have 20V output, those older 6th gen machines aren't as forgiving with the input voltages in the port. 5V, 9V and 15V likely won't work. I don't see anything more in the spec, they don't even say the port supports charging the laptop, only providing power delivery to charge devices on the port.
