Pros
- Built-in 30 A transfer switch hands loads to shore power automatically
- Doubles its output for 5 seconds, enough to start a small fridge compressor
- ETL listed to UL 458 with a marine supplement, so it passes RV and boat inspections
- Ignition control shuts it off with the engine so it cannot drain the battery
Cons
- Idle draw is not published, so overnight battery use is a guess
- App monitoring needs the Bluetooth remote panel, sold separately
- Hardwire only unless you buy the GFCI version or kit

#8 in Up to 1,000 WFull review
For a van, boat or truck cab that only needs to charge laptops and run small electronics. Very low idle draw and a five-year warranty make it a better long-term buy than a cheap 300 W unit.
