Hey, dude. If you want to use a USB-C charger, the system will support up to 140W in either USB-C port, but if you want to be conservative, technically, as low as 5-10W can charge the battery. However, since the system's intended power input is 230W, this is under 10% of the desired power input. This not only could compromise the system long-term, but you can also experience battery drain while the device is charging and drops in performance. For a decent substitute, sticking closer to the 140W max is optimal for charging with this system.
