Do Apple devices support Anker?

What do you mean by "support"? Apple doesn't provide warranty service for Anker products.

Anker does make products that work with Apple devices. I've seen Anker charging adapters recommended by a lot of people on these forums, ones whose opinions I trust.

You have that backwards.

It's not up to Apple to support cable, charger manufacturers.

It's up to them to build compatible cables and chargers.

If you have any questions about Anker products and what devices they support, best ask them.

any charger that is 5volt DC and have a connector that fits

would be support enough
