What this listing states. Six protections and cooling fan stated, so safety scores 6 of 10. 2-year warranty stated. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 4 of 5. See How We Pick.

Inverter limits. Stay within the stated continuous watts (surge watts last only a moment), use the cable size and fuse the manual gives, ventilate it, and never connect an inverter to home wiring yourself; that is work for a licensed electrician.
