Features & Benefits:

The world's first portable home battery ecosystem - DELTA Pro's expandable ecosystem provides you with power during blackouts, customizable energy around the clock, and lower energy bills. How does it achieve all this? With a selection of extra batteries, smart generators, solar trackers, wind turbines, a smart home panel, and more. From backup power to reducing your reliance on the grid with green alternatives, the DELTA Pro ecosystem can be customized to your needs. (accessories sold separately & coming soon)

All the AC output you'll need - A single DELTA Pro unit packs a 3600W AC output, which can be expanded up to 4500W with X-Boost technology. Power 99.99% heavy-duty devices at home, outdoors, or at work. You can even pair two units together to achieve 7200W.

Fastest charging portable power station - DELTA Pro can charge via one of 6 methods. It's the first that can be charged from an EV station, and can even Multicharge by combining methods to achieve a rapid 6500W charge. That’s the industry gold standard. 

Harness the power of the sun - EcoFlow's suite of solar products give you a cost-effective renewable energy source to stay powered. You can use solar energy to charge DELTA Pro in just 2.8-5.6 hours (1600w). DELTA Pro has a wide voltage range from 11-150V, which makes it compatible with 90% of third-party solar panels with MC4 connectors. And when the weather gets unpredictable, the smart maximum power point tracking (MPPT) automatically adjusts, maximizing your solar generation at any time of the day.

Emergency backup power - Disasters can occur at any time of the year, sometimes lasting longer than we ever expected. The EcoFlow Smart Generator serves as an emergency option that integrates with your DELTA Pro ecosystem. It auto-starts when your DELTA Pro hits a low level of charge, re-charges your DELTA Pro, and stops the engine all by itself once your DELTA Pro hits a full charge. Compared to a traditional gas generator, the EcoFlow Smart Generator delivers less energy loss, faster charging and higher efficiency. (sold separately & coming soon)

RV living made easy - With DELTA Pro, you can take home with you, wherever you go. It features wheels and a suitcase-esque extendable handle that makes transport easy. And if you’re looking for a complete power solution for RV road trips and outdoor adventures, DELTA Pro comes with dedicated 30A Anderson port and AC outlet.

A battery that lasts for years on end - DELTA Pro sports a brand-new LFP battery with 6500 cycles, which means you can use DELTA Pro for years and years before your unit reaches 50% of the original capacity. EcoFlow’s battery management system provides real-time analysis and regulation of voltage, current, and temperature. This unique protection mechanism makes DELTA Pro an incredibly safe and efficient home battery.

Control, monitor, & manage your energy use - Control DELTA Pro either on the unit itself, using the remote control accessory, or unlock a ton of customization via the EcoFlow app. On the app, you can access your power settings, such as charging and discharging levels, AC charge speeds, control the Smart Generator and a whole lot more.

Expandable capacity - With its add-on battery, it allows you to connect with a DELTA Pro to double total capacity to 7200Wh. Connect two of them to DELTA Pro for a staggering 10.8kWh to use off-grid.

Convenient recharging - Recharging from solar panels, AC outlets, EV charging stations, or our Smart Generator is easy. Plug the Extra Battery into DELTA Pro and they will recharge and discharge in tandem.

More watt-hours at home - The Extra Battery can be integrated to your home’s wiring when connected to DELTA Pro. These battery units become part of your home’s peak shaving and emergency power solutions.

Ready for emergencies - The Extra Battery can recharge directly from EcoFlow’s Smart Generator outdoors, giving you another option for emergencies.

What is Affirm?

Affirm is a financing alternative to credit cards and other credit-payment products. Affirm offers instant financing for online purchases to be paid in fixed monthly installments over 3, 6, or 12 months.

Why buy with Affirm?

  • Buy and receive your purchase right away, and pay for it over several months. This payment option allows you to split the price of your purchase into fixed payment amounts that fit your monthly budget.
  • If Affirm approves your loan, you'll see your loan terms before you make your purchase. See exactly how much you owe each month, the number of payments you must make, and the total amount of interest you'll pay over the course of the loan. There are no hidden fees.
  • The application process is secure and real-time. Affirm asks you for a few pieces of information. After you provide this information, Affirm notifies you of the loan amount that you're approved for, the interest rate, and the number of months that you have to pay off your loan -- all within seconds.
  • You don't need a credit card to make a purchase. Affirm lends to the merchant directly on your behalf.
  • You may be eligible for Affirm financing even if you don't have an extensive credit history. Affirm bases its loan decision not only on your credit score, but also on several other data points about you. 
  • Affirm reminds you by email and SMS before your upcoming payment is due. Enable Autopay to schedule automatic monthly payments on your loan.

What is required to have an Affirm account?

To sign up for Affirm, you must:

  • Be 18 years or older (19 years or older in Alabama or if you're a ward of the state in Nebraska).
  • Not be a resident of Iowa (IA) or West Virginia (WV).
  • Provide a valid U.S. or APO/FPO/DPO home address.
  • Provide a valid U.S. mobile or VoIP number and agree to receive SMS text messages. The phone account must be registered in your name.
  • Provide your full name, email address, date of birth, and the last 4 digits of your social security number to help us verify your identity.

How does Affirm work?

1. At checkout, choose Pay with Affirm.
2. Affirm prompts you to enter a few pieces of information: Name, email, mobile phone number, date of birth, and the last four digits of your social security number. This information must be consistent and your own. 
3. To ensure that you're the person making the purchase, Affirm sends a text message to your cell phone with a unique authorization code.
4. Enter the authorization code into the application form. Within a few seconds, Affirm notifies you of the loan amount you're approved for, the interest rate, and the number of months you have to pay off your loan. You have the option to pay off your loan over three, six, or twelve months. Affirm states the amount of your fixed, monthly payments and the total amount of interest you'll pay over the course of the loan.
5. To accept Affirm's financing offer, click Confirm Loan and you're done.   

After your purchase, you'll receive monthly email and SMS reminders about your upcoming payments. You can also set up autopay to avoid missing a payment.  Your first monthly payment is due 30 days from the date that we (the merchant) processes your order.

How does Affirm approve borrowers for loans?

  • Affirm asks for a few pieces of personal information: Name, email address, mobile phone number, date of birth, and the last four digits of your social security number. 
  • Affirm verifies your identity with this information and makes an instant loan decision. 
  • Affirm bases its loan decision not only on your credit score, but also on several other data points.  This means that you may be able to obtain financing from Affirm even if don't have an extensive credit history.

Does Affirm perform a credit check? Does it impact my credit score?

Although Affirm performs a credit check when you apply for a loan, this won't impact your credit score. However, if you're approved and decide to buy with Affirm, your loan and payments may affect your credit score.  Paying on time can help you build a positive credit history. 

Why was I denied financing by Affirm?

The merchant has no information regarding a customer's financing denial. Affirm strives to offer all credit-worthy applicants financing with Affirm, but isn't able to offer credit in every case. Affirm will send you an email with more details about its decision. Unfortunately Affirm's decision is final.

Why was I asked to verify my identity?

If Affirm has difficulty confirming your identity, you may need to provide more information. Affirm uses modern technology to confirm your identity, including verifying your address or full SSN, or requesting a photo of your ID. Affirm takes these steps in some cases to counter fraud and provide the most accurate credit decision they can.

Why was I prompted to enter my income?

Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. Your income gives Affirm additional insight into your ability to repay.

Why was I prompted for my checking account?

Affirm may sometimes need more information about your finances and your ability to repay in order to make a credit decision. If you are prompted to link your checking account and would like to proceed, please provide the login information for your online bank account. Affirm does not store your online login credentials---they are transmitted securely to your bank.

If Affirm asks you to link your checking account, Affirm won't be able to offer you credit if:

  • Your bank is not listed
  • You choose not to link your checking account
    You don't use online banking
    The username and / or password you provide is incorrect
    *You're unable to successfully connect your checking account

Why is my bank not listed?

Although Affirm is continually adding support for additional banks, they aren't able to connect to every bank at the present time. We apologize for the inconvenience. If you're unable to connect your bank, you'll need to complete your purchase with another payment method.

Why was I prompted for a down payment?

Affirm isn't always able to offer credit for the full amount you request. In these cases, Affirm asks you to make a down payment with a debit card for the remainder of your purchase. The down payment amount can't be changed and must be made upon confirming your loan and before the loan offer expires.

Will I see how much interest I am paying prior to accepting my loan?

Yes! Affirm works hard to be completely transparent. You'll see the amount of interest you'll owe on the terms page and again on the loan confirmation page. If you pay off your loan early, you'll receive a rebate for any interest that hasn't yet accrued.

Why can't customers outside the U.S. use Affirm?

Affirm is available only to shoppers residing in the United States. Affirm hopes to expand its services to customers outside the U.S. in the future.

What are Affirm's fees?

The annual percentage rate (APR) on an Affirm loan ranges from 10% to 30%. Affirm discloses any required fees upfront before you make a purchase, so you know exactly what you will pay for your financing. Affirm does not charge any hidden fees, including annual fees.  

Why is my Affirm interest rate so high?

When Affirm determines your annual percentage rate (APR), it evaluates a number of factors, including your credit score and other data about you. If you finance future purchases with Affirm, you may be eligible for a lower APR depending on your financial situation at the time of purchase.

This APR calculator will give you an idea of how much interest you actually pay: https://www.affirm.com/apr-calculator/

When you consider Affirm financing, carefully evaluate the loan terms that Affirm offers you and determine whether the monthly payments fit your budget.  

How is interest on an Affirm loan calculated?

Affirm calculates the annual percentage rate (APR) of a loan using simple interest, which equals the rate multiplied by the loan amount and by the number of months the loan is outstanding. 

This model differs from compound interest, in which the interest expense is calculated on the loan amount and the accumulated interest on the loan from previous periods. Think about compound interest as "interest on interest," which can increase the loan amount. Credit cards, for example, use compound interest to calculate the interest expense on outstanding credit card debt.

Excellent for Vanlife

The DP really is excellent for Vanlife. I'm using it connected to a 760W solar array on the roof and a additional 500W inverter to charge via the cars alternator. The option to charge with solar and AC therefore is just ideal. As I'm using a normal AC fridge and the idle draw of the inverter is quite high i added a small inverter to the Anderson port to reduce losses. This setup is perfect for me with my inductive cooking plate!

Outstanding Ecoflow products!

I started with the Ecoflow Delta Pro, and after seeing the quality and the real use case scenarios, I decided to get another with the Extended Batteries as well as the Smart Home Panel. With the 22KW I can now run my fridge, freezer, lights, outlets, microwave, mini split AC unit and more for about 6 days in case of an outage! In addition adding solar panels will help top off the batteries if needed and the Ecoflow gas generator is also ready to be used if needed. Completely love everything about this system, easy to set up and works like a tank! Thank you Ecoflow!

On wheels, lots of inverter capacity,& expandable.

After owning an EcoFlow R600 Pro when looking for a larger capacity watt hour power station and larger inverter my husband & I looked at all options available and selected the EcoFlow Delta Pro. Living in Florida we get lots of hurricanes and this power station was purchased to handle the power outages that happen. We've done a test run for a few days and we're all set when the power inevitably goes out next time. At the moment we're deciding whether to add on an extra battery to handle a longer outage. We've already purchased one EcoFlow 400W foldable solar panel and we're considering a second one as well. Living in a condo a solar generator fits the bill as gas & propane aren't allowed onsite here. Great product. Performs exactly as desired.

Delta Pro after 6 months

Preppers would love this unit. I purchased this to charge via my roof solar panels should the power go out for an extended period. I hope to get some more portable panels in the near future. I'm confident this until will meet my power needs in an extended grid down scenario. Things like a refrigerator, lights and maybe even the microwave. Thanks for such a great product. Tried to get a smaller unit 2 years ago from another company via indiegogo...disaster. Still waiting, and may never actually see the product and even if I do, I'm not sure I'll have confidence it won't burn my house down.

Secretly waiting for the next power cut!

After a few wildfire prompted power cuts and hassles with gas generators, I started looking for a battery-based unit to keep the essentials going without the gas smell, noise, and carbon monoxide risk. There seemed to be so many new options, but the EcoFlow Delta Pro really stood out. It is amazing how much they fit into this thing, not to mention the battery capacity and power output. The 400W solar panels are also really impressive — a bit heavy to carry around, but perfect for us to have ready here at home.
Now I find myself secretly waiting for another power cut so that I can connect up the EcoFlow!
