Hello everyone! I have a question about my laptop.
I have a rather old HP laptop with a round charging connector. The charger has an output of 19.5 V. I'd like to be able to use the laptop outside the house.
What kind of portable charger do I need to charge my laptop? And most importantly, are there any adapters to connect it to a laptop?
I will be grateful for your help!

Just get a cheap inverter, DC > AC, from a auto parts store and use a car
battery to power the inverter.

You can get power supplies that work directly for a car power socket that output 19.5V directly without first converting to AC.


If you're not in a car then a portable power pack isn't as practical as just purchasing a spare battery and carrying that with you to swap out when the original dies. For most (new) batteries, they last 4-6 hours off-charge so unless you plan to use the laptop for 12 hours continuously (or more) then one spare battery should suffice.
