EcoFlow Delta Pro Power Station

The EcoFlow Delta Pro is not a camping gadget — it's a serious power station built around a 3,600Wh LiFePO4 battery with a 3,600W continuous output inverter (7,200W surge). That's enough to run a full-size refrigerator, a microwave, a laptop, charge your phone and camera gear, and power LED lighting throughout your van — simultaneously. The built-in inverter outputs clean, pure sine wave AC power that's safe for sensitive electronics like laptops, CPAP machines, and camera equipment. No separate inverter purchase, no wiring, no installation.

Capacity is expandable. Each Delta Pro unit accepts an EcoFlow Extra Battery module, doubling your storage to 7,200Wh. Need more? Two Delta Pro units can be linked together for up to 14,400Wh — enough to power a small apartment, let alone a van. The system scales with your needs without rewiring anything. Add capacity by plugging in another unit. Remove capacity by unplugging it. Try doing that with a traditional battery bank bolted into your van's floor.

The 800W DC-DC alternator charger is the component that transforms the Delta Pro from a portable power station into a true van electrical system. Hardwired to your vehicle's alternator, it delivers up to 800 watts of charging power to the Delta Pro whenever the engine is running. A typical four-hour drive puts over 3,000Wh back into the battery — enough to fully recharge a depleted unit. The charger includes intelligent voltage regulation that protects your vehicle's electrical system and battery, drawing power safely without stressing the alternator beyond its designed capacity.

OZK Customs installs both EcoFlow portable systems and traditional hardwired electrical systems built around RedArc battery management and Epoch lithium batteries. Both approaches work. Both deliver reliable off-grid power. The right choice depends on how you use your van, how long you plan to keep it, and how much flexibility matters to you.

A traditional RedArc/Epoch system is the choice when you want a fully integrated, permanent electrical backbone that's wired into every corner of your van. It's ideal for full-time van lifers, complex builds with multiple circuits and dedicated loads, and owners who want their power system invisible — built into the walls and floors like a house. The RedArc Alpha manages solar, alternator, and shore power with fine-grained control, and Epoch batteries can be configured in any capacity and mounted in custom locations. It's the ultimate in customization and integration.

The EcoFlow Delta Pro is the choice when you value simplicity, portability, and flexibility. It's ideal for weekend warriors, part-time van users, and owners who want serious power without permanent vehicle modifications. You can remove it when you sell the van. You can take it into your house during a power outage. You can upgrade capacity by plugging in another unit instead of rewiring your entire electrical system. The 800W DC-DC charger gives you alternator charging — the one feature that used to require a permanent installation — while keeping the rest of the system portable.

The Delta Pro doesn't exist in isolation — it integrates with the rest of your van build. OZK installs a dedicated, ventilated compartment for the unit, typically in the garage area beneath the bed platform or in a rear cabinet bay. The compartment is designed with airflow channels that keep the unit within its operating temperature range, tie-down points that secure it during transit, and easy access for removal when you want to take it out of the van.

The 800W DC-DC charger is permanently installed in the engine bay with a clean, protected cable run to the Delta Pro's charging port. When you park and plug in the Delta Pro, it starts charging from the alternator automatically the next time you start the engine. When you unplug the Delta Pro, the charger sits dormant — no power draw, no impact on your vehicle's electrical system. It's the one permanent component in an otherwise fully portable setup.

For owners who also run solar panels, the Delta Pro accepts solar input directly — up to 1,600W across two input ports. Your roof-mounted Renogy panels connect to the Delta Pro without any additional charge controller. The unit's built-in MPPT controller handles solar optimization automatically. Combined with alternator charging from the DC-DC unit and the option to plug into any standard wall outlet at campgrounds or at home, you have three charging sources with almost zero permanent wiring.
