I need to get a setup going to run my laptop out of my car for a full workday (8hrs).
Strangely i cant find a lot of info on this.. (well nothing long term). But the thing to do seems to get a separate deep cycle marine battery, get a connection for a cig lighter and an appropriate ac adapter and use that. no inverter needed. Im thinking with a mix of plugged in & on battery, looking to get 3 days out of it. Laptop needs 20v & 90w.
Is that all I need?
How long will the battery last?
What/how about battery recharging?
Any help/insight is appreciated
