EcoFlow DELTA Max Portable Power Station
Home emergency power DELTA Max expands up to 6kWh with smart extra batteries, keeping your home powered on in any emergency.
Rapid dual charging Charge up from 0-80% in 65 minutes. Or get up to 3400W speeds by combining AC charging and the EcoFlow Smart Generator.
Power multiple devices Looking for something to power heavy-duty devices like your fridge and dryer? With X-Boost, DELTA Max handles devices up to 3400W with ease.
Best solar powered generator Stay powered on no matter what. DELTA Max connects with up to 2x 400W EcoFlow solar panels to deliver 800W Max solar charging speeds.
Live eco-friendly Use it as a solar powered generator for your home by powering appliances and tools on renewable energy.
Expandable home backup power.
A single DELTA Max unit packs a 2kWh capacity that is expandable up to 6kWh with DELTA Max smart extra batteries. This means when a blackout hits, you can continue to power your important home devices such as your fridge and lights for hours on end.
Convenient and fast dual charging.
DELTA Max charges up safely and rapidly from 0-80% in just 65 minutes. And it gets even better. If you’re looking for an even faster way to charge up DELTA Max, you can combine AC with the smart generator to get up to 3400W, AC with solar to get up to 2600W, or the Smart Generator with solar to get up to 2600W.*
Power 99% of your home devices.
With EcoFlow’s X-Boost technology, DELTA Max can power heavy-duty devices up to 3400W. That means during a power outage or blackout, you can continue to power your fridge, dryer, and more. That’s the industry gold standard for a portable power station of this size and capacity.
Harness the power of the sun.
DELTA Max connects with up to 2x 400W EcoFlow solar panels to deliver 800W Max solar charging speeds. With a voltage range from 11-100V and the Solar connector, you can also connect other solar panels to your DELTA Max. Even during cold or cloudy days, our smart maximum power point tracking (MPPT) algorithm automatically detects voltage and current in real time to give you optimum solar generation throughout the day.
Emergency backup power.
Disasters can occur at any time of the year, sometimes lasting longer than we ever expected. When extended blackouts hit, the EcoFlow Smart Generator serves as an emergency option that integrates with DELTA Max. It auto-starts when your DELTA Max hits a low level of charge, recharges your DELTA Max, and stops the engine all by itself once your DELTA Max hits a full charge. This gives you a reliable emergency backup option that relies on minimum use of a generator.
Control, monitor, and manage your energy use.
Control and monitor your DELTA Max with the EcoFlow app. Dive into the settings to customize your power use or control DELTA Max remotely.

Please include the following information:
- Order #
- The item(s) you would like to return
- Reason for your return
- Serial number of your item(s) (If applicable)
- Photos/Videos (If damaged and/or defective)
If you are requesting a return due to your item(s) being damaged and/or defective, then you may be required to also include photos and/or videos and go through reasonable troubleshooting to determine if the item is indeed damaged and/or defective.
If your request is approved, the return procedure will be as follows:
- We will either send you a Return Merchandise Authorization (RMA) along with the return address or a Prepaid Shipping Label depending on your reason of return.
- Securely pack all the returned items in the original packaging and include any other paperwork requested in the return approval email.
- We recommend taking a picture of the package and/or the item before shipping.
- Ship the package. We will either provide you with a return shipping label or you will have to arrange the shipping yourself. You can use UPS or FedEx Ground if your order was delivered by one of these carriers. If your item is larger and was delivered with one of the LTL freight carriers you need to make sure the box is put on a pallet and schedule a pickup with an LTL freight carrier.
- Once you ship the return package(s), please provide us with the tracking number(s) so we may monitor the status of your returned package(s)
- Once your return is received and inspected, we will notify you of the approval or rejection of your refund.
- If your return is approved, then your refund will be processed, and a credit will be automatically applied to the original method of payment within 10 business days.
In many cases if the item arrives and is not working, reasonable troubleshooting steps will need to be taken with the manufacturer to determine if the item is defective so we can proceed with an exchange if necessary and if approved by the manufacturer.
Please note, you will be responsible for all return shipping charges in cases of buyer's remorse. We define buyer's remorse as “an order that is returned because the customer changed their mind, didn't like the item (when nothing was physically wrong with it), the item didn't fit (when proper measurements were given), found a better price elsewhere, and/or ordered the item by mistake”.
For non-buyer’s remorse returns, shipping will be paid for by us. These include items that arrived damaged, items that don't work or are defective, or when the wrong item is sent.
Only after we receive your return and inspect the condition of your item or items, we will then process your refund for your return. Please allow up to 2 weeks for us to process your refund. After processing, it could take up to 5 business days for the refund to appear on your credit card statement. We will always notify you by email when your refund has been fully processed.
Deductions from your refund may include the following:
- Restocking Fees: For returns of "buyer's remorse" (defined above), there will be a 10% restocking fee.
- Shipping Charges: Original and return shipping charges will not be refunded unless the return is the result of our error.
- Returns cannot be accepted without prior authorization. Products must be new, resalable, and in the original packaging (some restrictions apply).
- It is the customer’s responsibility to return the product to the correct address in new condition and in the original packaging. For this reason, we strongly suggest that you obtain a tracking number for the returning item(s) and purchase shipping insurance.
- Avanquil does not guarantee your return request will be approved, if your request is not approved, then we will send an email with an explanation why your return request was denied.
- Returns cannot be accepted after 30 days from the date of delivery. If 30 days from the date of delivery has passed, then all requests will need to be directed to the manufacturer and your item(s) will be subject to the manufacturer's warranty policy.
- Returns need to be mailed back to the instructed location within 10 days of being approved, unless otherwise noted.
