USB-C charger for EN-EL15 batteries?

I traver very light and my pet hate is my Nikon's charger. Big, bulky, requires figure-8 cable and often a travel adapter.

Are there any USB-C chargers for EN-EL15 batteries worth recommending? I see a few dual ones on Amazon UK, but I would ideally want a single one that is as small as possible and won't burn my house down.

Anyone ever tried one?
