A:AnswerThe usb type C is Male, the usb type A (micro) is Female. I have search for a female C everywhere & have yet to find it in anything other than a hub. They don't want you transfer backwards, so you really have to hunt down an adapter to go from the newer standard to an older version they're trying to make obsolete so you have to buy new everything. And when you do find one, it may not work if it's just an adapter & not a powered unit, so check that out when you think you've finally found it!
I'm currently losing my mind searching for lightning hubs or a female C (thunderbolt) to male lightning. Sometimes it's easier to transfer it onto something else where it can then be transferred via cable, adapter, cable + adapter, sd card (usu with reader) or thin air (like text, email, Bluetooth, airdrop). Good luck! They really hate us not changing over so be creative :)
A:AnswerIt should but I have not tried it. I am planning to use it in reverse for my spare battery packs. However, the one I got through Best Buy did not work on my photo stick it seems that they are not all compatible. But that was the nice thing buying it from Best Buy I was able to return it and try different ones.
A:AnswerI use this on a Samsung Galaxy S10+ which uses a C type charger. Works great. So, if the Samsung A21 uses the C connector then this should work.
A:AnswerIf you have an older Micro USB (not mini USB) charger in your car, yes, this adapter will convert it to a USB-C charger. If the charger has a low amperage output (under 2.5 amps), it will take longer to charge your phone or your battery may still discharge while in use during a slow trickle charge.
A:AnswerThere is no cord with this adapter. It's just an adapter to work with all normal micro usb chargers so you can charge the new style fast charge.
