Can the Blade 15 handle 230V?

Check the details on your PSU of course but most laptop PSUs work over a range of voltages. For example, my RC30-024801 (PSU for Blade 15 2022) works from 100V-240V. I recently travelled from the UK to NA and had no problems with NA voltages at all. One would assume the opposite to be true but happy to be corrected. No point manufacturing different types of PSUs if you can just make one single type to fit all. I would buy a fused UK power cable when you get here though instead of using the adapters to get a solid connection but I will leave that on up to you!
