Why we chose it
  • Meet the all-new GENPRO10X2 – Similar to our GEN2, only better. It’s 19% smaller and delivers 33% more power. It’s one of the best performing onboard marine battery chargers we have ever made.
  • Enjoy precision charging – An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
  • Charge dead batteries – Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts.
  • Charging modes – Independently charge and control each battery bank with selectable charging modes – including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode – for all types of lead-acid and lithium-ion batteries.
  • Redefined mounting – A simplified mounting system allows for quick and easy installations in any direction – even up-side-down – with an integrated anti-vibration backing to isolate shock, vibration, and noise.
  • Designed for water – A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater.
  • Multiple banks – A two-bank onboard battery charger rated a 20-amps – 10-amps per bank – for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries.
