- Fits the opening of the Parallax/Magnetek 6345, Parallax 7345 and 8345, and WFCO 8945 power centers, so the breakers and fuses stay put
- Charge Wizard picks boost, normal and storage modes so a stored RV does not boil its batteries
- Wizard mode button lets you force a boost charge or check that the converter is working
- Lead acid only; for lithium you need the separate LIV model
- Costs more than a WFCO or PowerMax converter of the same output
- Two year warranty
