Odd that there would be no solder…thought that was pretty much mandatory for any port. I’d first make sure that the board hasn’t been damaged, and then if the port is actually intact, solder it (assuming there are actually pads and solder connections to join?). There are literally dozens of different ports so trying to locate the correct one can be a real challenge. I might just ask Nitecore about getting a part or a warranty replacement. If there’s no solder-fix, board is good, and you just need a port, you can hunt down the right one but you may have to buy multiples and/or not like the total landed cost. There’s a big youtuber in Californa (Northridge Fix, I think?) who sells ports individually on his company website but he’s geared more toward phones and computers…worth a look, though, and he’s got a handy comparison image that shows a good chunk of the port styles that are available (but not nearly all of them). But Nitecore might just take care of you for free or cheap.
