EcoFlow Power Kit 48V Cable

No more complicated wiring diagrams, no need for bus bars – with the new 48V Air Conditioner Cable you can immediately pair your EcoFlow Power Kit with a 48-volt RV air conditioner.

When we first learned of EcoFlow’s magical Power Hub and how all the typical camper van power electronics — inverter, charge controllers, DC/DC charger, DC/DC converter, transfer switch — were combined into one compact package, we also learned the Power Hub could, theoretically, have a 48V RV air conditioner connected directly to a battery port. We couldn’t stop until we tested it ourselves.

Our 48V air conditioner cable is designed to plug directly into the EcoFlow Power Hub. On one end, the cable has an integrated EcoFlow battery port plug, the other end has two bare 4 AWG conductors. To connect to your 48V air conditioner, the cable requires an inline fuse along the positive wire, but the bare ends allow you the flexibility to use butt connectors, Anderson connectors, or whatever connectors you choose. With our 48V cable you don’t need tools like king-size hydraulic crimpers, cutters, heat guns, or any of the other usual difficulties with building large-gauge DC cables.

The 48V air conditioner cable plugs into one of the Power Hub battery ports, so you’ll still have the two other battery ports free on the Power Hub, enabling you to have either a 4 kWh system (with 2 x  2 kWh batteries) or a 5 or 10 kWh system (with either 1 or 2 x 5 kWh batteries).

NOTE: A new EcoFlow firmware update — available now (Updated: October 22, 2023) — incorporates the new 48V cable’s power draw.

The 20 ft 48V Air Conditioner Cable plugs directly into the EcoFlow Power Hub, receiving 48V power supply directly and allowing you to choose the DC output from your Smart AC/DC Distribution Panel to either be 12V or 24V as needed. Once you know what DC loads you will be connecting to your distribution panel, you’ll set the DC voltage to either 12V or 24V.

To keep it simple: power efficiency. A 48V system uses less current to supply the same appliance than 24V and 12V systems, meaning thinner wires can be used and less heat generated in the system.

Additionally, the voltage will not affect the cooling BTU rating. All A/C units with the same BTU rating will operate with the same cooling efficiency; however, the voltage rating will affect the power consumption.

12V appliances typically will pull more power vs. 24V appliances and the same is true for 24V over 48V, so adding in a 48V air conditioner directly to your Power Hub lets you have a maximum power rating — and — a Smart AC/DC Distribution Panel that offers a built in step-down for either DC 24V or 12V loads.
