GIZZU GUDP36W Mini 36W 32Wh 8800mAh Dual Voltage DC Black UPS

I use four of these units to keep my modem and mesh routers alive during load shedding and power outages. Be sure to read the manual and set the voltage switch to the correct output.

This little monster lasted almost 8 hours during a power outage in my area, granted my router is very basic, only thing to note is that the cable that charges the unit is short, only 1m, but the wire coming from the unit to the router is about 2m, just make sure you set the correct voltage for your router,

All in all this is a very good investment if you just want to power your router.

4 stars for the short cable

Solid little unit. Has been performing well for me. Have it running the fiber and my router and it lasts for more than 4 hours.

I'm quite impressed.

Very good device!
Easily handles powering both a 12 V Optical Network Terminator (ONT) unit plus a 12 V WiFi modem/router.
Survives the nasty 4 hours double-load shedding sessions that we experience
Longest I had it operating while disconnected from mains before it shut down due to low battery, was just over 7 hours.
It does not have an external power brick, making a neat solution with battery and charger all inside the one compact unit.
Easy to recommend if you are looking for a solution to stay connected during the dark hours.

The little monster packs a solid battery life running my Asus router as well as my pi server. Very happy with this purchase. Would definitely recommend this.

This Is a awesome product for your fibre internet at home and the battery last quite a while too

Product works perfectly as advertised.
If I loose power during a video conference my meetings will continue unaffected even when the power comes on again.
