Hardkorr 12V Control Hub with 40A DC-DC Charger
High-Output 12V Power Management for Serious Tourers
The Hardkorr 12V Control Hub with 40A DC-DC Charger is the heavy-duty version of Hardkorr's best-selling power panel — designed for builds with larger lithium battery banks, high solar input, or demanding accessory loads. With a 40A DC-DC charger and MPPT solar regulator built in, this hub can push more charge into your auxiliary battery faster, meaning less time waiting and more time adventuring.
Like the 25A model, it features 17 inputs and outputs, a 500A battery monitor with shunt, 6 backlit rocker switches, full USB charging suite, Anderson plugs, and a pre-wired fuse block. The entire unit is pre-wired and fully fused — mount it, hook up your accessories, and you're ready to roll.

Who Needs the 40A Over the 25A?
If you're running a 100Ah+ lithium battery, a large solar array (200W+), or frequently doing long-distance runs where faster alternator charging matters — the 40A DC-DC is the better choice. It'll fully charge a 100Ah LiFePO₄ roughly 40% faster than the 25A model when driving.
