Looks like this may be a South African domestic brand though (and you probably don't want to order from a South African site unless you're living in the country to be honest). If it's just PoE you're looking for there are other options available - e.g. https://www.amazon.com/Battery-Uninterruptible-Security-10000mAh-Batterypack/dp/B07PHQNLFY https://www.amazon.com/Battery-Uninterruptible-Security-1000... One thing to be wary about though is max power if you're trying to run a raspberry pi with hard drive attached off one of these devices. A lot of these devices cap output on the USB ports at ~5V/2A (which I think was the USB2 max whereas USB3 allows for more). If you're running off an SD-card or SSD you should be fine, but 2A isn't enough to start a pi from an attached 2.5" HDD in my experience.
