This is the unbranded high-capacity option, and like the Charmast it leads with built-in cables: four of them, alongside a 27000mAh battery and fast charging. The combination of a large cell and no cable to remember is the pitch.

The listing does not carry a brand name, which means the evidence has to do the work instead. It carried 5,795 ratings at 4.5 stars at the time of collection, a small but solid sample. As always, the rated capacity is measured at the cell rather than at the port. Everything here comes from the Amazon listing rather than our own testing.
