The EcoFlow Alternator Charger Custom Fit Output Cable Links Your Alternator Charger to the Extra Battery Port on DELTA Pro and DELTA Pro 3

The EcoFlow Alternator Charger Custom Fit Output Cable is a 2m cable that runs from the Portable Power Station Port on an EcoFlow Alternator Charger to the extra battery port of a compatible EcoFlow power station or extra battery.

It is for drivers and RV owners who pair an EcoFlow Alternator Charger with one of six EcoFlow models.

EcoFlow Alternator Charger Custom Fit Output Cable Features

Made for Six EcoFlow Models

EcoFlow lists the cable as compatible with EcoFlow DELTA Pro, DELTA Pro 3, DELTA Pro Smart Extra Battery, DELTA Pro 3 Smart Extra Battery, DELTA 3 Max Plus and DELTA 3 Ultra Plus.

Connects Through the Extra Battery Port

It plugs into the Portable Power Station Port of the charger and the extra battery port of the power station or extra battery.

Same Operating Modes as the XT150 Output Cable

EcoFlow says the charger's usage and operating modes are the same as with its XT150 Output Cable. With that cable, the charger supports Charge Mode, Battery Maintenance Mode and Reverse Charge Mode.

2m Length

The cable is 2m long, which gives you room between the charger and your power station.

Real-World Applications

Charging while you drive. In Charge Mode, the charger uses your alternator's spare power to charge the power station as you drive.

Keeping a starter battery charged. In Battery Maintenance Mode, the power station keeps the vehicle starter battery charged over an extended period.

Helping a depleted vehicle battery. In Reverse Charge Mode, the power station charges the vehicle starter battery or RV house battery.

Practical Comparison

Custom Fit Output Cable Versus the XT150 Output Cable

The XT150 Output Cable is for EcoFlow power stations or extra batteries with an XT150 extra battery port. The Custom Fit Output Cable is for the six models above. Both give the charger the same modes.

Custom Fit Output Cable Versus the XT60 Output Cable

With the XT60 Output Cable, the charger connects to an XT60 input port and supports Charge Mode only. The Custom Fit Output Cable adds Battery Maintenance Mode and Reverse Charge Mode.

Buyer Guidance

How the Modes Work

Power on the power station or extra battery first to use Charge Mode. To change modes, use the device detail page in the EcoFlow app. EcoFlow's manual for the 500W Alternator Charger lists up to 500W in Charge Mode and Reverse Charge Mode, and a default maximum of 100W in Battery Maintenance Mode.

This May Be A Good Fit If

You own an EcoFlow Alternator Charger
Your power station or extra battery is one of the six models
You want all three charger modes

Exactly what I ordered

Exactly what I ordered. Great quality and the updates that are given as to when it was shipped and when it should arrive is amazing.

Generator works

Generator works. Have yet to try solar panels. Will have to wait for a sunny day! Just wish I was more tech-savvy. Feel a little overwhelmed… but I am satisfied w purchase

It charges the battery on a cloudy day

This battery charges lightning fast has a light and multiple charging ports and two sockets. It has 2 way power, from the solar panel and the wall outlet. Definitely purchasing from this seller again

Trusted Since 2025 – Highly Recommended!

The generator cord looks longer in the pictures than in real life. It is 18” long from tip to tip. I received the cord on time and in excellent condition. I have not used the cable at this time as it is for power outages only. I’ve recommended Outboundpower.com to everyone for a vender of solar and power station equipment. They have been a favorite of mine since 2025.

Hi Homer, thanks so much for the kind recommendation and for trusting us for so long! We’re glad your adapter arrived on time and in excellent condition. Thank you for your note about the length and hope it’s ready when you need it. We appreciate you!

Was wrong about last review

Email discomunication and other led to my last review,when spending a lot on solar equipment I was lead to believe what my sales person had told me,,they said they would send a email where I could get a discount for my purchase,I waited patiently and it never came,so I thought I could trust them and made the purchase anyway hoping for the adjustment,I finally got it,but they have reach out to me,and because they do so much business they get tided up with other things,I believe that are the best people to buy solar from,things just got of hand,please know that they have done an excellent job for me and others

Hi Todd, thank you for updating your review and for your kind words. We’re sorry for the email miscommunication, but glad we were able to follow up and get it sorted out. We truly appreciate your patience and trust, and we’re grateful you chose us for your equipment!

Excellent work

Jam sales agent did a first class job, products and prices were better than I could get anywhere. They did a great job. I miscalculated some things, but found out that they were all in my favor. Thanks to the team at Outbound Power.

Hi Todd, thanks so much for the kind words! We’re delighted that everything worked out in your favor. We truly appreciate your support. You are the best!

First class treatment by Outbound Power

I give this a five star rating because of the service that jam help me with,, generators, batteries, solar panels, wires, breakers, shut off everything, and I am not an expert at putting this all together, but she straightened me right out. Oh, I had to do is get my electrician to hook up to my breaker box which wasn’t a big deal rest was very easy,, and jam also helped me with the pricing and it was just the first class Five Star Job by Outbound Power I love him and if I get anything else, it will definitely be from jam and Outbound power company.

Hi Todd, thank you for the wonderful five-star review! We’re so glad Jam made choosing and putting together your backup system easy and helped you find the right options and pricing. We’ll be sure to share your kind words with her. Thanks for choosing Outbound Power — we’re here whenever you need us!

My second purchase with Outbound Power

My second purchase with Outbound Power. I wanted to expand the capacity of my Delta Pro 3, and they gave me a really good price on the Delta Pro 3 extra battery. It was shipped quickly and for free! Got it connected easily to the Delta Pro 3 with the included cable and it began charging immediately. Very pleased with the battery and with Outbound Power!

Hi there, thanks for choosing Outbound Power again! We’re glad you had a such a great experience. We truly appreciate you!
