Anker is above average, but the bar for average when it comes to Chinese electronics is, "might not burn down your house immediately."
For reasons probably bordering on OCD, I watch a LOT of teardown videos of various electronics. And one thing that always strikes me is how a company with a product will routinely and often change what's inside, while the model number and exterior appearance stays the same.
For example, I wanted to buy a big 12V LiFePo4 battery and all of the cheapest ones are on Amazon. Amazon reviews are generally garbage because they're all borderline fake (from useless Viners, or wanna-be useless Viners). The only "honest" reviews of these I could find were YouTube teardowns where they basically have to destroy the case in order to take it apart. I would watch a teardown of one popular battery, and then run across a different teardown of the same model from someone else and the internals of each would be completely different. Completely different cells, battery management board, wires, construction everything. But they both looked identical on the outside.
Finished product manufacturers in China rarely have a consistent supply chain. They are negotiating suppliers and batches of components constantly, and are constantly re-engineering everything about the product, except for the external appearance of the case. This Luma Field article confirms what I've already run across myself.
This is also obvious if you think about installing OpenWRT on a router. You'll quickly find out that there's often various versions of the same product; it used to be that they would mark it somewhere, but that doesn't always happen anymore, and only some versions are compatible.

Samsung goes a bit further. Depending on where you buy e.g. a S23 FE, you'll get entirely different SoC architectures - the US model ships with Qualcomm Snapdragon, the international model with Samsung Exynos.
