It started out great. Then 4 months in the were occasional drops in the battery power. Now only 9 barely months after first purchased. It's completely failed and stopped working. Cannot get it charge the battery and it won't stay on for more than 30 seconds.This device will let you down. Don't bother unless you want to be disappointed.

None of the connectors seem to fit a BT Hub

Upon opening the box, you are met with a small white electronic box which is a very similar size to the Apple TV box but it’s white.The unit is powered from either a USB adaptor (not included) however there is a USB to 12v lead, or you can power it directly from a 12v power supply (not included).The battery system consists of 3 18650 batteries with numerous outputs, see photos included.The output tolerances in terms of volts is within +/- 0.5v which is very good for a product of this price.In terms of what it’s good for, I would certainly use this for an internet router or CCTV cameras, or even a 12v door bell.
