It's difficult to get large battery packs right. In order to limit the possibility of catastrophic runaway of the pack you have to have extremely robust inter-cell or inter-module thermal isolation and heat rejection. These features are basically non-existent at the handheld power bank scale. It'll be interesting to see Anker enter this space of large batteries. Either they'll work really well and you'll see them quietly get installed in lots of places, or they'll be in the news when they have a series of runaways and light some balconies on fire. That being said, a lot of the risk gets taken out with lower charge and discharge currents vs a vehicle application.
