Hard to find a more capable battery at this price

This is the slightly higher specced version of the Elite 200 v2. The only difference is probably in the software limitations.

Anker SOLIX EverFrost 2 40L

We have only used it once since owning, but works great. We can wait to use on our longer family trip. No more need to get ice, no more water dripping from the coolers. Ours had no issues when it arrived. FedEx tucked it up next to our garage to keep it out of the rain. Thank you to everyone.

Hi James,

Thank you for your kind review! We’re so glad to hear the Anker SOLIX EverFrost 2 is working well for you — and that it arrived safely and without issue (props to FedEx for keeping it dry!).

It sounds like it’s already making a great impression, and we hope it makes your upcoming family trip even more enjoyable — no more ice runs or soggy coolers sounds like a win!

If you have any questions as you continue to use it, feel free to reach out anytime. We’re always happy to help.

Mistakes made but corrected!

While the bag is nice enough. The size description was way off. What they have now is closer to correct. They have since reached out to me and issued an RMA. The bag has been returned and a refund issued. Mistakes happen, but this company made it right!

Hi William,

Thank you for your honest review. We truly appreciate you giving us the opportunity to make things right. While we regret the initial issue with the product sizing, we're glad we could resolve it promptly with the return and refund.

Your understanding means a lot, and your feedback helps us continue improving. If there’s ever anything else we can assist you with, we’re always here to help.

Outstanding service

Just wanted to let you know that the Anker Solix F3800 plus, with an expansion battery, and the generator cable arrived promptly and in excellent condition. I want to mention that your company does the right thing, even though the customer may not know it. When I ordered the equipment, I did not know that there was a promotion for a free solar panel based on the amount of the order. I was happily surprised when the free solar panel was delivered.
Rest assured that I will recommend your company as it has the best prices around, and because it does the right thing for it's customers.
Thank you!

Hey Jesus,

Wow, thanks so much for sharing this — it made my day! I’m really glad everything with your Anker SOLIX F3800 Plus, the expansion battery, and the generator cable arrived quickly and in perfect shape. And I love that you were pleasantly surprised by the free solar panel — we always try to take care of our customers, and it’s awesome to hear it made a difference for you.

Thanks a ton for your kind words and for planning to recommend us. If you ever have any questions or just want to chat about your setup, you know where to find me!

Shipping and packing

The batteries shipped and delivered a day early.
They were packed very well.
Installation went well.
Need a longer batery cable to hook up the batteries in series.

Power cord exactly as I expected

This power cord functioned exactly as one would expect it would, and was receive in good time.

Thank you for your review! We're glad to hear the power cord worked as expected and that it arrived on time. If you ever need anything else or have questions, feel free to reach out — we're always here to help!

took a chance & pleasantly surprised.

I wish my ecoflow 800 watt alternator generator came with the proper cable for my ecoflow delta pro. I even checked on a question and answer on this same potential issue and the response said is was compatible. but it turns out that it's not and know I need to order an adapter for it. so in essence your response was via ecoflow stated information, but their info is not as model specific I guess. just a general, blanket response across the board?

still on your end 5 starts, this is a tech info issue on their side if you ask me. another way to generate more money instead of adding the go between attachment in case of these scenarios or just making a 1 standard cable/plug in for their entire product line ;)

Thank you so much for the thoughtful review and the 5 stars — we really appreciate it. You're absolutely right to point out the confusion here. The compatibility information provided by EcoFlow can sometimes be too general, and unfortunately, it doesn’t always highlight the specific adapter requirements between different Delta models and the 800W Alternator Charger.

We completely understand your frustration, and we agree, clearer, model-specific guidance would make things a lot easier. We're actively working to improve the accuracy of the compatibility details we provide and are passing your feedback along to EcoFlow as well.

If there's anything we can do to help expedite your adapter order or make things right in the meantime, just let us know. Thanks again for your support and for helping us improve!
