EcoFlow 4G Dongle for DELTA Pro Ultra, a small black module with a USB plug

The EcoFlow 4G Dongle for DELTA Pro Ultra Portable Power Station (PPS) Connects Your Inverter to the EcoFlow Web Portal Over 4G

The EcoFlow 4G Dongle PPS is a plug-and-play communication module for the DELTA Pro Ultra. It plugs into the inverter's 4G dongle port and uses a 4G network to connect the inverter to the EcoFlow Web portal.

It is for DELTA Pro Ultra owners who want a mobile network connection, such as where Wi-Fi or Ethernet isn't practical. A nano SIM card is included.

EcoFlow 4G Dongle for DELTA Pro Ultra Portable Power Station (PPS) Features

Plug-and-Play Installation

Insert the nano SIM card, then plug the dongle into the 4G dongle port on the DELTA Pro Ultra inverter. It connects through a USB 2.0 Type-A interface with a 5 V input.

Included SIM Card, Activated in the App

Activate the included data SIM card in the EcoFlow app by entering the APN details from the card and tapping Save. The SIM works only in this dongle, not in other 4G modules or third-party devices.

Clear LED Status

With the inverter on, the LED blinks white slowly while dialing or when there is no signal. It blinks white rapidly when the inverter is communicating with EcoFlow Web through the dongle.

Small and IP54 Rated Once Installed

The dongle measures 3.4 x 1.7 x 0.6 in (87.5 x 44 x 16.3 mm) and weighs about 35.1 g without the SIM card. It is rated IP54 once installed in the inverter's 4G dongle port.

Real-World Applications

No Wi-Fi at the inverter. Where there is mobile signal but no Wi-Fi or Ethernet, the dongle connects the inverter.

Checking in from afar. Reach your system through the EcoFlow Web portal over 4G.

Alongside your home network. When Ethernet, Wi-Fi and the dongle are all connected, the inverter uses Ethernet first, then Wi-Fi, then 4G.

How It Compares to Common Alternatives

Versus Wi-Fi or Ethernet. Both need a home network that reaches the inverter. The dongle uses the mobile network instead.

Versus a third-party SIM or 4G module. The included SIM works only in this dongle. EcoFlow warns that non-standard or incompatible SIM cards can damage the card and the dongle.

Is This 4G Dongle the Right Fit

Inverter model. EcoFlow lists the DELTA Pro Ultra inverter model EFYJ751-PCS-US.
Mobile signal. EcoFlow suggests a 2G signal of at least 4 bars or a 3G/4G signal of at least 3 bars.
LTE bands. It supports FDD-LTE Bands 2, 4, 5, 12, 13, 25 and 26.
Handling. Don't remove the SIM card while in use. Avoid high heat and humidity.

This may be a good fit if

You own a DELTA Pro Ultra
Wi-Fi or Ethernet isn't practical at your inverter
You have a stable mobile signal where it sits

Common Questions

Does It Come With a SIM Card?

Yes. A nano SIM data card is included. It works only in this dongle.

How Do I Know It Is Connected?

A rapid white blink means the inverter is communicating with EcoFlow Web through the dongle. A slow white blink means it is dialing or has no signal.

What Temperatures Can It Handle?

It operates at −20°C to 45°C.

Doesn’t work

Instructions are very vague and can’t get it to work

Hi Chris,

I’m sorry to hear the 4G dongle didn’t work out for you. I’ve tried reaching out a few times via text, email, and phone to offer assistance, but I understand you’ve likely been busy these past couple of weeks.

If you decide to revisit setting up the dongle for your Delta Pro Ultra, here’s a quick guide to help you get started:

Step-by-Step Setup
1. Use a data-only SIM card plan from any carrier that provides service in the U.S.
2. To access the SIM card slot, press both side buttons on the dongle and remove the cover plate.
3. Adjust the SIM card to fit the pre-cut slots as needed.
4. Insert the SIM card and slide the cover plate back into place.
5. Connect the dongle to the top-left tab of the Delta Pro Ultra inverter. This should enable 4G functionality.

Note: Some carriers require the SIM card to be activated by contacting their support team before use.

Here’s a helpful video tutorial that simplifies the process:

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!
