Welborn Usb C battery for Nikon

[Sayangupta]

Anyone here have any idea on welborn Usb C batteries for Nikon? If any one have used them? I am looking for one EN EL 15  battery. Both small rig and K&F concept make usb C batteries but they don't ship to India due to lithium ion battery regulations. The only cheap option I am getting  is of welborn on Amazon. Please suggest

Quick update- Since no one in the forum commented on this , I had no other option and bought the battery to check. To my surprise this was well packaged , charges quickly and in my last 3 wildlife trips lasted for entire day when used with my D850. Overall I am happy with the purchase till now not sure what will happen in long run. But for the price they are offering nothing to complain here. I am getting these batteries at 1.7K only where as the original ones are close to 4K and don't offer USB C charging as well. I will update late after long term usage.
