Okay so I need some community help with this one. I ordered a Anker Power core 20100 Portable charger, but I noticed that the one I got didn't have a USB - C port. It has 2 USB 2.0 and Micro USB. So I wasn't sure what I should do with it. I had got it for my nintendo switch and my Laptop which both have USB - C ports. So I was wondering, is it safe to use a USB adaptor with it or just get another one with the proper USB port? I read from a flow chart that direct USB - C to USB - C is the best result for charging the system and not a USB 2.0/3.0 to USB C or any kind of Adaptor. People reported that playing games like Breath of the Wild will still drain the battery but just slower, instead of charging it, unless the system is fully inactive, in sleep mode or shut off. The one I got was $40, but the one with usbc is $65 so I would like some insight on what I should do.
