That panel is way too small. 7W cannot charge a modern smartphone/tablet by itself (those are usually 10W+) and will take forever just to charge up the battery pack. For the MSRP of $120 you can get a 28W panel and still have $50 left over for a good battery bank, type C or otherwise.
This is just stupid marketing, don't fall for it.
