20A DC-DC CHARGER
40A DC-DC CHARGER
The 20A DC-DC Charger has increased charging efficiencies compared to previous
models from 85% to 95% and charges your battery quicker. Compatible with a large
range of vehicle and solar panel combinations, the compact unit allows for easy
fitment.
The Thunder 40A DC-DC Charger with MPPT solar regulator allows an increase in
your battery capacity while still charging smoothly and faster than the 20A DC-DC
Charger. The inclusive MPPT solar regulator gives you the benefit of extracting
maximum power out of your solar panels, rather than relying solely on your
alternator and resulting in hitting the tracks sooner.

What’s the difference between the 20A and 40A?

Physically larger unit = larger capacity

40A has twice the capacity of 20A = quicker charging

Larger 550W solar input = quicker charging
