Router Battery Backup

Okay so I did open the unit as I do have a couple of extra 18650's. However, you have to somehow solder them or get them connected in parallel to make it work and I have tried twice now and struggling to get them connected, not the best electrician out there. Also don't think the device is a solid charger, or maybe it is. Just don't wanna try and save money and after getting it to work, it turns out exactly the same as the previous one.

Which one do you have?

Morning all..

Need your personal opinion...

This : https://www.takealot.com/elecstor-100w-mini-dc-ups-24000mah-75wh/PLID91634884
Or this : https://www.wootware.co.za/gizzu-gup60wpro-60w-69wh-21600mah-black-mini-poe-dc-ups.html

Also had one of the cheapies, lasted for 3 years and did a good job but barely making 5 minutes now so batteries obviously depleted and degraded.

They are roughly the same price.

I have that Gizzu 60W/69Wh model and am very happy with it so far, other reviews seem positive too.

Looking at the specs they both have LiFePO4 batteries and you get a slightly higher 75Wh capacity on the Elecstor. On the other hand the Gizzu has (gigabit) POE functionality, as well as some odds and ends like a better selection of adapters/cables and a 20W 'solar input' so one could charge from one of those little emergency charging panels in a pinch.

I guess it may come down to whether you may use the POE functionality or not...

How long does it support a laptop for?

I use one of the Netogy units for my HP Pavilion laptop (ditched the battery a couple of years ago when it swelled up). The original power supply for the laptop is rated 19.5V and 2.31A (45W). The Netogy handles the 2-hour slots without dipping below 50% and mostly manages a 4-hour slot, occasionally shutting down about 15 minutes shy of 4 hours.

That is decent - thanks.

re 4 hours: Not sure how it would manage that. Are your actively using the laptop during the 4 hours? Your laptop would need to draw only 11w in order to last 4 hours on one of these.

What cpu does it have?

Probably excel with the screen brightness turned down to minimum with wifi disabled using a lan cable. It like how long is a piece of string question.

Netogy is 14 400mah, my laptop has a 4400mah battery and that lasts about 2 hours, so with that is should last at minimum 4 hours.

Depends on how much power your laptop draws. It only has 46wh if I am not mistaken. (I.e 46 watts for 1 hour)

I have a Lenovo G50-80 with i5 CPU, and at a guess, would be close to his HP Pavilion.

So with it's battery that lasts about 20 minutes, that should get me over the 4 hour line.

Although the mAh figure is only really comparable if the voltage on the cells is the same, so using Wh is generally a better way to compare. I think the laptop batteries I have are all substantially higher voltage than the LFP cells in my mini-UPS, so to put it another way one gets more Wh from a given number of mAh from the laptop battery. Your laptop battery may well have a similar Wh capacity to the Netogy.

This ^^^ mah is not a good way to determine capacity *unless you have the cell voltage (volts x amps = watts)
