I've had Amazon Basics cables that weren't up to spec, yes. In fact most Amazon Basics electronics products have been poor quality of those I've purchased (mostly cables and a couple sets of speakers) so much that I won't even buy anything labelled as such now.

Not directly addressing your question, but Amazon did a recall on their own chargers included with UK and Ireland Fire tablets, and recalled over quarter of a million portable AmazonBasics chargers.
