Dolphin Charger DC-DC Booster Dual Output 12V 25A/18A Fan — Built for Euro 6 & Euro 7 Vehicles
Our new double-output DC/DC booster is engineered for modern Euro 6 and Euro 7 “smart” alternators found in recreational and special-purpose vehicles. It delivers a stable, controlled charge to your service battery while simultaneously powering critical 12V loads—all without upsetting vehicle electronics.
Compliance you can trust: This unique, European-patented design is E-marked to ECE R10, confirming automotive EMC compatibility and simplifying approvals for OEMs and converters.
Why it matters for Euro 6/7
Smart alternators use variable voltage and regenerative braking to reduce emissions, which can starve auxiliary batteries of charge. Our booster stabilises input, lifts voltage as needed, and enforces the correct charge profile—so your service battery charges fully and predictably while driving.
Boost your charge!
True double output: Charge the leisure/service battery and power a fridge or heater at the same time, from one compact unit.
Consistent performance: Maintains correct charging even with fluctuating alternator voltages typical of Euro 6/7 systems.
Battery-chemistry friendly: Works with Lithium (LiFePO₄), AGM, Gel, and Flooded batteries (configure to suit your chemistry and manufacturer guidance).
Scalable power: Need more capacity? Parallel operation lets you increase available current for larger builds or multi-appliance vans.
Boost your manufacturing process!
Industrial Plug-and-Play connectors: Speed up installs, reduce wiring errors, and improve repeatability on the line.
Converter-friendly layout: Clearly labelled I/O and keyed connectors support rapid QC and reduce rework.
Compact footprint: Frees up space in tight services areas and under-seat installs.
Documentation-ready: ECE R10 certification and straightforward wiring schematics make approvals and handover packs easier.
Boost your stock management!
One SKU, multiple use-cases: Compatible with the most common battery chemistries and appliance types (compressor or absorption fridges, heaters, etc.).
Parallel-ready: Cover a wider range of van specs and upgrade paths without proliferating part numbers.
Future-proof choice: Designed around current Euro standards and typical converter requirements to minimise obsolescence.
