(Mini DC UPS (7800mAh) Backup Battery Power Bank Supply (28.86Wh) - 12V + USB: Router, CCTV, Wifi Backup) :
Excellent service and product
I'd like to first of all comments on the excellent service, communication and delivery time from Geewiz.
As for the product itself, it comes with various sizes of DC tips with the cable so it fit my router and my fibre ONT. I'm assuming it arrived almost fully charged since it took less than an hour for it to indicate that it is fully charged.
I then (since there is no load shedding currently), intentionally switched off the wall AC outlet and it indeed keeps the devices powered seamlessly, 0 downtime. It's now been about 4 hours with the outlet switched off and my connection is still going strong.
I personally bought 2 of them, one for the fibre ONT and one for the router since they are both rather high power models. If yours are not very power hungry you should be able to use a splitter cable at the output and have one power both devices for s couple of hours.
