Based on your question searching for a mini UPS for your wifi router, I would recommend either the 36W 10400MAH MINI Ups For Wifi Router Or Cctv for R496 or the JG********0MAH MINI Ups For Wifi Router With Poe Port for R798. Both of these options provide over 10,000mAh of backup battery power which should provide several hours of backup time for your wifi router during power outages. They are also small and portable enough to sit near your router. The JG766 model has an added benefit of including a Poe port which could be useful if you have any Poe connected devices to power as well. Let me know if you need any other details on these models or have additional questions!
Based on the router model you mentioned, the Astrum BP070 MINI Ups 10400MAH and the 36W 10400MAH MINI Ups would both be compatible options. They have a 10,400mAh battery capacity which will provide hours of backup time for your router during power outages. Both UPS devices output at 12V which matches the voltage required by your TOTO Link router. Their power ratings of 18W and 36W exceed what your 600Mbps router would typically use. Of the two, I would recommend the 36W 10400MAH MINI Ups for the higher power rating to provide a suitable safety buffer. It's priced around R496 according to my previous PriceCheck search. I hope this helps narrow down a compatible mini UPS for backup power for your WiFi router! Let me know if you need any other details.
