Comment on Thinkpad for the win
Mcdolan@lemmy.world 3 weeks agoThe “best” would be some kind of DC to DC converter, but I’m not sure there’s anything plug and play atm because there’s a wide range of specs laptops want. If your laptop happens to change with USB c PD or whatever the spec is that’d be the most efficient that I’m aware of. No sense in going dc->ac->dc if it can be helped.

Modern laptop chargers can actually run on DC current, and with as little as 48 volts. Here is a german guy demonstrating it. So if your battery bank runs on 48 volts, I think you might be able to just connect it directly to the input of a laptop charger and it will work.
