What's a suitable fuse for New 3DS XL?

I've got a faulty New 3DS XL which I bought as dead. I switched the battery and it runs fine, but the issue is that it won't charge or power on when connected to the mains. I swapped the daughter board, so the issue isn't the fuse on that, at least not exclusively. I connected a charger and read 5V on the inside of the power connector, so that isn't damaged. I assumed at this point that the issue is the fuse on the mainboard, but couldn't find any info on what fuse would actually be a suitable replacement. Anybody know?
