The Joey unit is interesting. I assume the screenshots are from a companion cellphone app? And being a “smart” device, I suppose it needs access to all the features on your cellphone, it needs to be connected to the internet and it wants you to setup an account? 
I bought all my powerbanks-cum-chargers because, being a vaper, I’m always hunting for 18650s with juice in them - particularly when I travel. But they’re from vaping supplies companies, made in China, and somewhat rough on the edges and feature-poor if I’m honest. Their only claim to fame is the replaceable batteries thing.
