Hi I purchase the Anker Power Core Slim 1000 But ....

However, I thought it would work for my cellphone, only the smaller side of the plug in didnt fit my A 20 Samsung Cellphone, I need a cord with USB on one side and a smaller plug that will fit into a A20 Samsung Cellphone Can anyone help??? See, I go to the hospital A LOT, but im not able to walk so getting to a plug once im in a bed is impossible for me, if I have the power bank I could then use it to keep my cellphone from dying while im in the hospital. Please let me know ASAP squeeky472@outlook.com

Is this your phone?

Is this your power bank?

Then what you need is a USB-A to USB-C cable, something like this:
