As of October 16, 2026, EcoFlow’s DELTA 3 Ultra deal requires a live-page and checkout check. The company’s detailed US sale terms list the 3,072Wh portable power station at $1,349, down from a stated $1,599 non-member price (a $250 saving), but those terms ended October 5. A later EcoFlow announcement describes selected Prime Big Deal Days offers running through October 18, so the $1,349 price should not be treated as guaranteed without confirming the exact listing and final cart total.
What the advertised $250-off deal includes
EcoFlow’s US Prime Day Fall Sale page identifies the product as “DELTA 3 Ultra (3072Wh) Portable Power Station.” The advertised final price is $1,349 versus a $1,599 non-member price, with “SAVE$250” shown on the listing. The same listing states 3,600W output and promotes readiness in 89 minutes. These are EcoFlow’s published specifications and offer claims, not independent test measurements.
The promotion is for the 3,072Wh DELTA 3 Ultra power station. The listing information does not establish that solar panels, an extra battery or another accessory is included. Treat it as a standalone-unit offer unless the product page or cart explicitly names a bundle and lists its contents.

Why the timing is confusing
EcoFlow’s detailed promotion terms say the offer began September 20, 2026, at 12:00 a.m. PDT and ended October 5, 2026, at 11:59 p.m. PDT. Eligibility was limited to residents of the continental United States; Alaska, Hawaii, Puerto Rico, Guam and the US Virgin Islands were excluded.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
In a September 21 announcement, EcoFlow described Prime Big Deal Days savings on selected products as running September 20 through October 18, with selected products reaching lower prices on October 6–7. EcoFlow’s September 30 guidance identifies Amazon’s 2026 Prime Big Deal Days as October 6–7 and tells shoppers to verify the model, any coupon and the final checkout price. Those statements create a genuine difference between the expired detailed terms and the broader promotional window.
How to check whether $1,349 is still available
- Open the current EcoFlow US product page and confirm the title says DELTA 3 Ultra (3072Wh) Portable Power Station.
- Check the displayed price, membership or Prime requirement, and whether a coupon must be selected.
- Confirm the package description: standalone DELTA 3 Ultra or a bundle with named accessories.
- Review shipping eligibility for your continental-US address and any delivery charge.
- Place the item in the cart and verify the final pre-tax total. A banner or list price is not enough if the coupon does not apply at checkout.
- Repeat the checks on Amazon if you are comparing that listing with EcoFlow’s own store. Match capacity and model name exactly before comparing prices.
EcoFlow store versus Amazon
EcoFlow says selected Prime Big Deal Days offers are available through both its website and Amazon. The two listings can differ in coupon rules, membership qualification, shipping, returns, warranty presentation and included accessories. Compare the delivered checkout total rather than relying on the headline discount.

The DELTA 3 Ultra is most relevant if you need a high-capacity portable battery and can use its stated 3,600W output. Before buying, list the devices you intend to run, their wattage and the required runtime; 3,072Wh is a capacity rating, not a promise that every appliance will run for a fixed number of hours. If you need solar panels or expansion batteries, price those items separately unless the cart clearly includes them.

Bottom line on October 16, 2026
The $1,349 price is a documented EcoFlow offer for the 3,072Wh DELTA 3 Ultra, but the detailed terms ended October 5 while a later announcement extended selected Prime Big Deal Days savings through October 18. Check the live EcoFlow or Amazon listing and the final checkout total on the day you buy; only then can you establish whether the $250 reduction, membership conditions and standalone-unit configuration still apply.
