Don't have any information about a list, but I'm certain you'll have no issues if you buy one of the popular brands. Aukey, Anker, and Ravpower come to mind but there are others. All are available from Amazon and can be returned for any reason.
Personally, Insignia is not a brand I'd buy. They're a mixed bag; some products are fine, others are garbage. Insignia is not OEM. BB sells many different products under this name and all are private labeled from the manufacturer. Some manufacturers may supply a decent product, others not. Also, many Insignia items aren't discounted that much.
There are universal specs for all USB chargers. Of course, there is someone out there selling substandard product, but any products that have substantial sales will be made to the specs. Google has no unique spec that isn't available from other sellers.
This all pertains to plug in chargers. Wireless can be a bit different.
