| Nov 10, 2020 at 20:01 | comment | added | Jon Custer | Inverters are pretty efficient, so just go with Watts and get amps on the 12V side from that (i.e. 11W for the laptop is 1A@12V). Also remember that even for an AGM battery you should not discharge much below 50% of the rated Amp-hours, lithium may be better but has its issues as well. Finally, a dc-dc converter (e.g. RedArc) may act as a battery isolator as well (and some stand alone battery isolators won't work well with modern alternators, which would include your vehicle). | |
