AC power bank to power laptop

[Ags]

Can anyone suggest a power bank capable of powering a laptop. My laptop by the way is a Dell G5 (nice graphics card and hexacore processor), so a bit overspecced and power-hungry for running Sharpcap and Synscan. The power bank I can think of is the Bresser one...

I think that using 230V is not necessary and you'll only loose power in conversion.

Laptop usually requires around 18V for charging but is capable of running of 12-14V (not charging).

See if you can find device that powers your laptop from car 12V plug and then just use led acid battery to provide you energy?

Note: This adapter can also be used to connect the laptop directly to a 12V battery. It also works if your laptop battery is dead or without internal battery.

This one will definitely run your laptop from an AC- powerbrick, i ran my fridge with this during a blackout for a test and it does work under heavy loads admirably. Though it wont power a laptop for long probably since the inverter side of the powerbank wastes fair bit of energy.

I have seen a lot of love for this powerbank previously on some threads before
