Modified or true sine wave inverters
Gord & the group:
"Many consumer batteries, chargers, & adaptors, such as computers, battery drill motors etc, require a true sine-wave input for safe/effective long-term reliability."
I have heard this for the last 5 years, yet have not found it to be at all true. We use a Freedom 10 modified sine wave inverter/charger and, over the last 3 years, have relied on it full-time to operate an amazing breadth of chargers & motors plus 2 laptops - how DID all these things get on my boat!? - and have had zero problems. My guess is that this is heritage advice based on earlier designs. Our Freedom is now 5 years old, so it''s certainly not state of the art...but we find it truly good gear, and quite versatile.
