About RVPowerFit

Check a 12 V RV or van house-power setup (lithium battery, converter, DC-DC charger, solar, inverter) against your loads: days of power and a compatibility checklist, from published maker specs.

How it works

Specs come from maker product pages, spec sheets, and manuals. Every number shows where it came from. See the methodology and the safety page.

Independence

RVPowerFit is an independent site.

We do not test products and hold no electrical certifications. Verdicts compare published specs; they are not installation advice.
