Anker Power Bank - needs bit more power to use something (Adafruit PiTFT 2.4" HAT Mini Kit - 320x240 TFT Touchscreen)

[MarkIpswich]

I've got an Anker Power Bank 26,000mah (not the Power Core +)

Input: 5V ⎓ 4A (5V ⎓ 2A Max Per Port)
Output: 5V ⎓ 6A (5V ⎓ 3A Max Per Port)

I've been using that to try and install a Adafruit PiTFT 2.4" HAT Mini Kit - 320x240 TFT Touchscreen on a PI 3B+ model. I am unable to as I get the low voltage warning, as it needs a bit more power to use it (3.3a)

I could use a plug but I just want to use a power bank with it.

I do believe I need a dual USB and micro USB cable so I can get enough power from the bank to the PI board for it to work.
Is that correct?

I need someone to be 100% sure it will work with using it.


If yes, then would this be the correct one that I need?

I realize you need to know before you order and I get that, but perhaps you might be able to cheat a bit.
You can power the Pi3 B+ through the GPIO pins, applying the 5V directly to them. Depending on how comfortable you are with a soldering iron and some splicing.

You would need to cut up a few random USB cables to obtain the USB A male plugs, though.
Sadly that's all I've got.

I would rather not do that. I just want only to get a working cable for it (if there is one that does work) and nothing else. I do not need anything else as I have what I need for it.

Or even this one which I forgot to add.
