Windows 7: Battery Backup For Laptop When Power Outage?

4 Weeks Ago   #11

Windows 10 Pro

Okay i looked through this thread again.

So im on my laptop and use 2 monitors. But when power outage happens, i only use my laptop and have maybe 1 hour battery because laptops shut off.

So if i want to have a few hours on my laptop, do i get a power bank or the UPS? I will not connect it to a desktop or monitor. But i connect it to monitor, that uses power very quickly right?

So if i get the power bank i linked, how long can i get with that with my laptop? If i get a power bank, would it be longer? Example 1 hour of battery i have on my dell xps 15 9550, then when power goes out, i connect to the power bank. How long would i have on it before i have no more power? What about the UPS? So its actually possible to get like 5 hours of battery on my laptop if i buy like 2 or 3 of these UPS? So all these UPS is compatible with my dell xps 15 9550? So what if i get a power bank like the one i posted? How long would i get with that?

Did you read my post #8?
12000mAh is only 12Ah. Very little capacity.
You have to tell us what equipment s you want to stay on and for how long.
Do you live on a house or on an apartment?

Small apartment.

A dell xps 15 9550 laptop. Example there is a power outage. Then im on the laptop battery only and i get between 1 hour to 1 hour 15 minutes no it. Now when im almost out of battery on my laptop battery and plug it in, how long would i get on my laptop assuming the 18000 mAh?

You can use a UPS like CyberPower UPS
When the main power goes out, it will begin to use the UPS battery. When the UPS battery discharges, it will automatically begin to use the laptop battery.
If you want to extend the time, you can replace the UPS battery with one or more car batteries (70Ah)


A small generator. Quiet Portable Generator
With the generator you don't need the UPS. When the laptop battery is bellow 40%, start the generator and (with an extension cord) plug the laptop charger on it. You must place the generator on a window (exhaust pointing out). The generator noise can be a problem with your neighbors.

Of course don't run a generator in a house. You'll die of carbon monoxide poisoning.

Same for using gas heaters in a tent without adequate ventilation.
