Has anyone found a USB-A to USB-C adapter? I want to be able to use my Anker Power bank to charge my 2018 iPP 11" but it only has USB-A ports. I saw there are a few on Amazon and some of them state it does NOT work with the new iPP.

If there isn't one out yet, what have people been using? USB-A to USB-C cables?

You mean like this one ? I have it and I use it to connect my iPhone Xs Max to my iPad Pro’s Charger. You can also use it to connect the iPad Pro to a standard power bank too with the appropriate cable.

i'm actually looking for the opposite adapter so I can plug the USB-C cable into the adapter and use a power bank or charging black with a standard USB port.

USB-C female to USB-A 3.0 male adapters are made and are available in various forms from retailers like Amazon. There are also USB-C male to USB-A 3.0 male cables that provide the connection pattern in a single piece. Most likely support USB-3, but some may only support USB-2. None can support USB-PD (Power Delivery)

While these will allow you to physically make the connection, it is unlikely that the device will charge. Modern USB-C devices use the Power Delivery (USB-PD, or just PD) spec, generally rev 2.0, which specs 5v, 9v, 15v and 20v charging at various current levels. The device and charger negotiate the voltage to be supplied by the charger. The older USB charging protocol was 5v only, though there have been some proprietary quick charging variants (Qualcom, ...) that offered 9v when proper negotiation was present and would fall back to 5v when absent.

A charger, whether battery or mains powered, that has only a USB-A female connector will not be able to support the extra data communication needed for PD and won't likely provide the full range of voltages. The device will likely not charge at all if the PD negotiation signals are absent. I know that my Surface Go will ignore a USB 5v charger connected via any type of USB-c <> USB-A cabling.

Thank you for the information. This probably explains why i can not find the adapter... I suppose my only option is to use the linked cable above or buy a new power bank with a USB-C port.
