    Power Outages - If your power goes out during a storm you can use DELTA to keep your heater/AC running in your home or greenhouse. You can also plug in lights, chargers for your devices, and power for cooking appliances to keep things comfortable. 

    Multiple Charging Options - If there is no sun you can charge DELTA using a regular outlet or a car charger if you are off grid or the power is out.

    Fastest Charge on the Market - DELTA can go from 0% to 80% in one hour which is 10 times faster than other solar generators on the market.

    Get Rid of Your Gas Generator - Gas generators are loud, heavy, cause pollution, and you can't use them indoors. With DELTA you won't have to worry about any of those things.

    Chaining Ability - You can chain DELTA to another DELTA to increase capacity.

    Shelf Life - DELTA has a ONE YEAR shelf life when fully charged so you can be prepared for anything.

    Off Grid Living - DELTA can be used while it is charging, attach solar panels to power your RV, van, tiny house, or campsite anywhere you are!

    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:

    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. 

    How long does it take DELTA to get fully charged by a 110W solar panel?

    - DELTA supports solar input ranges from 10V to 65V with a maximum allowed current of 10A and maximum input of 400W. At perfect sunlight it takes:
    a. 1x 110W solar panel: 16h-32h
    b. 2x 110W solar panel (in series): 7.5h-15h
    c. 3x 110W solar panel (in series): 5h-10h
    d. 4x 110W solar panel (in parallel): <4h 

    Can I charge my DELTA through the DC and the AC port at the same time?

    Yes, and when DELTA is charged through the AC and DC port at the same time, it will prioritize taking in power through the AC port. After you unplug the AC cable, DELTA will start taking in electricity through the DC port.

    What is the charging time when DELTA is charged with an AC cable?

    - DELTA can be recharged to 0%~80% in 1 hour, and be fully recharged in 1 hour 40 minutes.

    Can I use DELTA to charge my devices while it is plugged into the car port?

    - DELTA can be recharged through your car port and power your devices simultaneously.

    What is the water proof level of EcoFLow solar panels?

    - The solar panels are IP67 rated so they can still function in the rain but the performance of the panels depend on how much sunlight is available. You can rest the solar panels on the car roof, the boat roof and the roof of your house for efficient and convenient solar power (You can purchase EcoFlow's suction cups separately to help attach the panels to flat surfaces).

    Can DELTA be used inline as a UPS for uninterrupted power?

    - DELTA supports an entry-level UPS function. But please perform multiple tests to confirm compatibility before connecting such devices as data servers and workstations with DELTA. EcoFlow will not be responsible for any loss of data or equipment damage caused by customers’ failure in following the instructions.

    Do the AC ports support pure sine wave or modified sine wave?

    DELTA's AC ports support pure sine wave. As a result, when you plug your electronics in DELTA, they are well-protected with less generated electrical noise and longer-lasting motors.

    Is DELTA equipped with an MPPTT controller?

    DELTA is equipped with the EcoFlow patented fast-tracking MPPT controller, which is supported by EcoFlow's unique tracking algorithm. This algorithm helps maximize the solar input under any weather condition. DELTA supports any solar input ranges from 10V to 65V with a maximum allowed current of 10A and a maximum input of 400W. You can chain your solar panels in series or in parallel to maximize the solar input.

    Can DELTA charge EV?

    DELTA support charging most of the models from Tesla (Model X, the new version of Model S, Model 3) except the old version of Model S.
    *Please note: In order to meet the UL2743 standard, DELTA's sockets are not grounded. However, after conducted hundreds of tests on different electronic vehicles, the results is that only Tesla needs a grounded cable, others with grounded chargers can all be charged by EF DELTA properly.

    What is the noise level of DELTA?

    In the Noise Test Chamber

    Test condition:
    1. Noise Tester: TES-1357
    2. Ambient noise: 33.8dB
    3. Test outcome: the average outcome from the front, back, right, and left

    Test results:
    Condition 1: AC outlet: <500W; the fan: 10% full speed, <40DB, 2-meter distance; Condition 2: AC outlet: 500W-1200W; the fan: 30% full speed, <45DB, 2-meter distance;
    Condition 3: AC outlet: >1200W; the fan: 100% full speed, <50DB, 2-meter distance

    Can I use DELTA for my off grid house?

    Yes, you can! If your house is not off-grid, please cut off the connection between power grid and your house before powering your house using DELTA.

    What type of cables can be used to connect solar panels to DELTA?

    The cable that can be used to recharge your DELTA by solar panels is MC4 to XT60 cable, and this cable is included in the packaging of DELTA.

    Can I charge DELTA using the RIVER series AC cord?

    DO NOT use RIVER series portable power station AC charging cables on DELTA series power stations. EcoFlow takes no responsibilities for any damages caused by customers' failure to follow instructions. Doing so will void the warranty.
