Router Battery Backup

Thanks all for the suggestions!
I was hoping for a cheaper solution than the mini-UPSes, as power banks tend to be quite cheap - Was hoping one may support passthrough.

Same cable yes. Not sure about the ratings. Will have to check.
Wonder what @Shr1k3 wants to power.

I've recently setup HomeAssistant, and I've powered an Intel Compute stick with my Gizzu Mini-UPS that's already in place by splitting the DC 5.5x2.5 output with this:

and a modified a 5.5x2.1 to USB cable, adapted to micro-USB for the Compute Stick:

Next I would like to have my Google Home Mini powered with a UPS, however I'm not too keen to spend more than R600 on a power solution for that.
 
As mentioned before I have a small charger board. I have the battery and the router connected to the output of the board which has a set output of 12.58 Volt, don't want to push it higher.the board has an 18v transformer on the input. When power is on the board charges the battery and powers the router, when power is off the router runs from the battery.

The downside here is that I don't want to set the output higher than 12.58 v as my router is a 12v unit. So that's a bit low for charging the battery.

To get around that I am going to get another board, they are very cheap and connect that between the battery and router.

Care to share what board it is?
 
I have been wondering whether I could provide a solar panel as input to this board and have it connected to the battery, cannot see why not? The solar controllers and regulators help with protecting the battery from over charge. This device if it's set to say 13.8V , it will only charge the battery if the battery is below 13.8V.

The little board has adjustable amperage output as well, up to 5A. Input up to 35V and output up to 35V, which suggests it could charge a 24V/26V battery as well.

I have used simialr step up and down buck converters in our CCTV systems to backup 24V , and 9V radios and switches. They seem quite sensitive little things, but the ones we have installed already have un for many months already without glitch.

I have a 12v 1 amp Huawei Telkom ONT and a Netgear 12v 5 amp router
How do I calculate how many hours a mini UPS will last? I find the 10400 mah ones from TL, just make it for 2 hrs in spite of reviews stating it lasts longer
I bought the

Gizzu 100W DC 46Wh Mini UPS Black https://www.takealot.com/gizzu-100w-dc-46wh-mini-ups-black/PLID73887358​

from TL and it lasts 4 hours, yet with Level 6 load shedding it does not seem to have enough time to charge between the cycles to last another 4 hours
What type of specs must I look for? I am confused by the wh and mah and watt to evaluate the mini UPS

Rather replace your router for a lower powered one. I have the same UPS & the Asus router I had, used 19v 1.75A. (I ran it on 12V from the UPS) My new router uses 12V 1.5A & after 4 hours loadshedding is still around 75% charge & takes less than an hour to charge back to full.

Thanks Which one are you using? Or suggestions?

I went with the Asus rt-ac58u, it's a pretty good budget router. I'll probably setup the old one in mesh mode when I have time, it's been gathering dust for months now.

Have an Ultralan 32Wh unit exactly like that which has served us really well over the last 18 months. Very happy with it considering the number of cycles it's been put through.

Been wanting to order a slightly larger unit that can get the router/ONT through the longer outages which are becoming more frequent, and have been holding out for the new Gizzu 60W/69Wh GUP60WPRO model as it has LiFePO4 batteries unlike their older 60W/65Wh model. Not much stock around though, seems like everywhere sold out a month or so ago, although their other models are available. Finally saw it pop up on Takealot yesterday with a "shipped in 5-7 days" note and managed to order one before it sold out again... now to see if I get sent the right model!

I was looking at getting the 60W/65Wh model? What batteries are you saying it has? on the takealot description it says lithium as well?

Glad I saw this

With their new 60W/69Wh/21600mAh model they've moved to LiFePO4 batteries (which per the Syntech interview recently they'll be doing with many of their Gizzu UPS products this year). The older 60W/65Wh/17600mAh model just states 'lithium-ion' as many of these small UPSs do, I assume it's NCM chemistry but not 100% sure. I pretty much only get LiFePO4 batteries these days so thought it was worth waiting for stock of the new model to arrive, seems it's widely available now and mine is set up and working well. Should be good for more cycles over its lifetime which is why they're moving their products to LiFePO4.

The new 60W model has 12*1800mAh LiFePO4 cells, the older one 8*2200mAh 'lithium-ion' cells, the LiFePO4 cells have slightly lower voltage hence the significantly higher mAh figure but only slightly higher Wh. The smaller Ultralan unit I used to use had four of those 2200mAh cells and is still useful after 18months and probably 1000+cycles, but has lost some capacity and with the frequency of outages these days the more durable the battery the better obviously - worth paying a bit more imo but you'd still get good use out of the older model which is being discounted it seems.

Thanks for the detailed response! <3 I will go with the newer LiFePO4. And yeah I also noticed the older models are now on discount. Edit: just listened to the syntech interview very interesting.

For anyone reading Serval tracker is a awesome takealot price tracker. To see if you getting a good discount. Similar to Keepa / camelcamelcamel for amazon. Just found out about it recently.

Going to try one of these:

I went for it because it's relatively cheap for a LFP model. I'm hoping it will last longer than the NMC models in terms of charge cycles.

Not so cheap for a 10000mah power bank but you can leave this plugged in. Its basically a charger and a power bank in one.

This charger is loadshedding proof! - South African Consumer

It happens from time to time, it's been a long day at work, you just got home, your phone is almost dead, you take your shoes off, plug your phone in so that it doesn't die while you check the notifications and poof: LOADSHEDDING! Wouldn't it be nice if your charger could charge even after

I use my phone a lot for work and can't get stuck with a dead phone so i got one and so far it works great i mostly use it in the car not heavy or bulky no more worries to make sure everything is charged.

Thanks for sharing :thumbsup: been looking for a pass-through power bank for a while.

I also have one of these that I keep plugged in by my bedside. It's great to know that I can charge anything at any time.

The only slight issue I have found is that it doesn't always switch automatically. I.e. I would sometimes plug something in and it may stop charging the device when the power goes out. Then I have to unplug the device form the usb cable and plug it back agian and It will start charging.

This is not a train smash for me but it may be a problem for someone that is looking to use it as a UPS that always remains on.
