How buying this works
Roam Wired does not stock this item. The button above hands you over to the seller's own shop, where you place the order, pay and arrange delivery directly with them. Nothing is added to a Roam Wired basket, and we never see your payment details.
We list it because it is the part our calculator would specify for a build like yours, not because we make the most on it. How we make money
Delivery and returns
Delivery cost, delivery time and the returns window are set by the seller, not by us, and Roam Wired's own £10 / free-over-£250 UK delivery does not apply here. Check their delivery and returns terms on their product page before you order.
Your consumer rights, including the 14-day right to cancel a distance sale, are against the seller who took your order.
Warranty and support
The manufacturer's warranty is handled by the seller you buy from. If something fails, raise it with them and quote their order number — we cannot open a claim on your behalf.

Overview
REGO 12V/24V 30A DC-DC Battery Charger
30A, 450W, and it works on 12V or 24V at either end. The REGO 30A is the flexible one: 12V to 12V, 24V to 24V, or across the two. Add RS485 and Renogy CAN, and a five-year warranty, and it is the charger to pick for a system you expect to change.
- 30A maximum output, 450W
- 12V or 24V input and output, 9–32V DC out
- ≥94% charging efficiency
- RS485 and Renogy CAN
- IP43, heat-sink cooled, 2.0kg, 239 × 156 × 69mm
- 5-year material warranty
Why 24V capability is worth having
Most van conversions are 12V and will stay that way. But if you are working on a larger vehicle, a 24V chassis, or a build where a future move to 24V is plausible, a charger that handles both saves buying twice. It also means the same part number works across a fleet running mixed voltages.
Talking to the rest of the system
RS485 and Renogy CAN let this charger share information with compatible Renogy batteries, controllers and displays rather than working blind. Where the BMS reports a real state of charge, the charger can act on it. Mixing brands, you fall back to voltage-based charging, which still works — just less cleverly.
Before you order
IP43 is dust-protected and splash-resistant, not sealed — mount it inside the habitation space rather than underfloor. Recommended operating range is −35°C to 65°C, and it is cooled by heat sink alone, so leave air around the fins.
