Portable power station / UPS

[tgw]

I need to be able to run a rather beefy laptop during blackouts, my laptop's power supply is rated for an output of 19.5V, 11.8A and 230W.

I need to be able to run the laptop for at least 6 hours.

 

I looked into UPS, but these are usually providing power just for a handful of minutes.

 

Then there are portable power stations, such as Jackery and a few other brands.

 

Does anyone here have experience with this kind of setup?

The Jackery website offers calculators and simulators, which say for example that a certain power station size can recharge a laptop 20 times while being able to power it for 4 hours straight, for example.

 

I don't know which size to choose or if I should go with number of charges or continuous draw, and I don't exactly know my laptop's average draw while working but not using the GPU, but powering an LTE aircard (USB dongle).

Check the restrictions of the maximum power outputs of the unit if you intend to  carry in a plane.

When, where, why, and how frequent are the blackouts?

A typical UPS has a 8Ah battery. The time it can run  depends on the load, but basically intended for enough time for short black outs (brown out)  or time enough to safely close down.
