Router Battery Backup

But the current would matter when it wants to draw more than you have available, right?

Lets say it can recharge at 12V, 2A so 24W but you give it 12V, 1A so 12W. It will recharge at 1/2 the speed that it is capable off.
And then lets say the device that you plug into needs 24W, you'll drain it faster than you charge it...

This is why I say the "same or slightly more" current than what is required.

Yes that makes sense.

Some people use split cables on these ports . If you split them, I guess the voltage stays the same but the current is split between the 2 devices if the 2 devices both pull the same amount of current. Is this correct?

Yes I think so. Well, not sure about the Voltage, but current should split according to how much is being drawn by each device. After all that's how any power supply works eg. multiport usb chargers have a total current that they can handle across all the ports.
 
Eish! That sounds dangerous. If you use a charger/transformer rated at 1 amp to supply a unit that draws 2 amps, then you are overloading the 1 amp device. It will probably get hotter and hotter until it....

more likely the unit just won't switch on

If it’s a pos it will get hot and eventually fry but if it’s made correctly it’ll be just fine. In general with power supplies and battery chargers you pay for the amperage they provide, like a car battery charger could be 4A or 8A and the only difference between charging a 100Ah battery with either is the time it will take to complete the charge, using the 4A charger on it won’t damage the charger.
 
Hi. Hope you guys are well. I am looking for some assistance. When it comes to router back up just need to make sure I purchase the correct one.
Power rating :
ONT: 12VDC - 1A
WiFi: 12V - 1.5A
Router :12V - 0.5A

Poduct I'm interested
Gizzu 60W DC 65Wh Mini UPS - Black

Will this work, is it enough. What other information do I need to provide?

Wait watt was your question again?

I noticed this is a 56wh while the one I linked is 60wh. What difference does that play and what are the drawbacks

I have one of these. It does ONT and two routers way over 4 hours.

Well it is cheaper. And does not involve scam-alot so i would give it a go.

Just a question on battery degradation. If I understand correctly dropping a battery below 50% and then charging it to 100% degrades it quicker than if it was say above 50% or is that a myth?

It's lithium (LiFePO4). You can drop it to almost 0% without any harm.
 
Hi All,

Any recommendations for a backup that will last at least 3 hours, just looking at keeping fibre and switch going, these are the power requirements :

Switch - 9V/0.6A
Router - 5V/3A
ONT - 12V/1A

TIA!
