Pros
  • Galvanic isolation keeps the starter and house circuits separate, which suits boats and mixed-ground systems
  • Detects when the engine is running, so it works with smart alternators without an ignition wire
  • Set up and monitor it from your phone over built-in Bluetooth
  • Add more units in parallel later if you need more current
  • Five-year warranty
Cons
  • Only 87% efficient, so more alternator power turns into heat than with newer chargers
  • No solar input
  • Heavy and bulky for 30 A next to the Orion XS
