Mini portable uninterruptible power supply

Recently i received this mini portable uninterruptible power supply (UPS) that i ordered after seeing a YouTube video of this interesting device. On AliExpress it is advertised as "Mini Portable UPS Router 5V 9V 12V Uninterruptible Power Supply for WiFi, Router Large Capacity Backup Power Adapter Ups Backup"

From the title you and seeing two Ethernet connectors you could think it contains a router or Wifi, however Ethernet connectors ar only available as this small power supply also can provide power over Ethernet (PoE). With a small switch you can select between 15V or 24V PoE.
Is also has a 5V USB outlet and 3 sockets providing  5, 9 and 12 Volt. It has a lithium battery and a circuit to act as UPS when main power stops. On top is an on and of switch and an indicator showing charging level. A European and USA type cable are provided for the main power voltage. Also included are a 'normal'cable and a 'split' cable for the 5,9 and 12 volt connectors.
It is a nice device that maintains power in the event of a power failure and provides some often used voltages. The 5V USB connector is also useful to have. It is not possible to draw all the advertised power at the same time and the power output is somewhat limited. For example it is not possible to power my FritzBox router using this device. If it could power my FritzBox i probably would have ordered immediate a second one to keep my network on in case of a power failure.
