This is my first order from outbound and I must say will certainly not be the last. Constant, relevant communication throughout the order process and fast delivery. Outbound has become my “go to” for all my EcoFlow needs.
Thank you, Josh! We're thrilled to hear that your first experience with Outbound Power was a great one. Providing transparency, fast shipping, and great service is what we aim for. We appreciate your trust and look forward to being your go-to for all things EcoFlow!
The river 3 plus is a great power station. I’m very happy so far. It does what I want it to do. I like the app. It’s quiet. It’s very nice looking too.

Ease of use, veteran discount, personalized customer service
Personal touch via email. Easy to use veteran discount. Some sites offer a veteran discount but you have to dig for it and/or it's hard to use. Price matching made quick and easy. Since I've had such a positive experience why should I chance another store when you all will price match lowest price?
Thank you, Terry, for your detailed review. We're glad to hear that our personal email service, easy-to-use veteran discount, and quick price matching have made a positive impact on your experience. Your loyalty and trust mean a great deal to us, and we're honored to be your go-to store. We'll continue to work hard to provide you with the best value and service possible. Thank you for choosing Outbound Power.
Thank you for your feedback! We're glad to hear that your Anker SOLIX BP1000X Expansion Battery arrived on time and that you had a great experience with our customer service. Your satisfaction is our priority, and we're here if you need any further assistance.
I bought my dual fuel 3000 to basically charge my other EcoFlow solar generators when they run low. Solar is very slow so this is a good solution. It was a great price from outbound power performed. Well I prefer to use the propane as it’s much cleaner, also, it does not use the carburetor so the less trouble with the carburetor to me the better. it’s a really good product very well built very easy to use and got a great price.
Hi Jerry,
Thank you for sharing your detailed feedback about your dual fuel 3000. We're pleased to hear that it's a great solution for charging your EcoFlow solar generators when solar alone isn’t enough. It’s great that you appreciate the propane option, especially since it’s cleaner and avoids the complications of a carburetor. We're glad you found a good price with Outbound Power and that the product is working well for you.
If you have any questions or need further assistance, please don't hesitate to reach out.
I ordered the F2600 and it has been great so far. I ordered the BP2600 as well and had a few issues but Anker customer support has been really excellent with responding to my questions. I will continue to monitor for issues but for my home backup situation I feel much more confident for emergency scenarios. Also, Outbound Power was absolutely excellent and I highly recommend you make your power station purchases there.
Hi there,
Thank you for sharing your experience with the F2600 and BP2600. We're glad to hear that the F2600 has been working great and that our service has met your expectations. It's good to know that Anker's customer support has been responsive in addressing the BP2600 issues—you deserve a seamless experience, especially when it comes to your home backup needs.
We appreciate your trust in Outbound Power and your recommendation. If you encounter any further issues or have questions, please don't hesitate to reach out. We're here to help ensure you're always prepared for emergency scenarios.
Love mine. The feature that attracted me most was the water resistance. I mostly use this dry camping with my camper. I have other power staions with a ttr 30 plug, which is important to me, and take great pains to keep them sheltered and dry but worry about the unforseen. Stuff (rain) happens! I'm less worried about this unit. I've seen YouTube reviews of people spraying these with water and leaving them in the rain without mishap. I don't plan to do that but glad to know should it happen, it should be fine.
It runs all my camper AC appliances just fine, microwave,
Keurig, etc. I've even run my camper's 13,500 btu ac unit to see if it would. I don't plan to use it for that because it probably wouldn't go more than an hour. Just nice to know I could. I've tested it on my home refrigerator and upright freezer without problem. I figure about 16-24 hours on the fridge and maybe a couple of days on the freezer with a power outage (without expansion battery) but haven't tested it to that extreme yet. Probably some YouTube videos out there that test that more thoroughly.
The video reviews I've seen give battery capacity an efficency around 85% which is considered good. I do have the expansion battery but haven't really tried it too much but figure it will significantly increase my runtimes. I plan to add more expansion batteries over time.
Seems to charge well on solar but there are voltage limitations. I'm waiting for Bluetti to release their PV voltage regulator which as I understand it allows you hook up an array of solar panels and it will maximize the input. AC charging is adjustable with 3 modes and can charge it up pretty quickly if you want.
It's heavy but seems on par with other brands of the same capacity.
My experience with Outbound power has been exemplary. They answer my emails quickly. Ship quickly and offer a hassle free veteran discount through GovX. They've priced matched for me twice. I've made 4 purchases from them far and have consistently gotten excellent customer service. These things are expensive and it's good to know you're dealing with someone who's going to stand behind the sale. Ymmv
It suites my needs well
Hi Terry, Thank you for sharing such a detailed review. We're delighted to hear that the BLUETTI AC240P is proving to be a great fit for both camper and home backup use, and that its water resistance gives you added peace of mind during dry camping. Your insights on its performance with various appliances and the potential for future expansion are truly appreciated. It means a lot to know that our customer service—whether through quick email responses, hassle-free veteran discounts, or price matching—has met your expectations consistently. We strive to stand behind every sale and ensure our customers feel confident in their purchases. If you have any questions or need assistance as you add more expansion batteries or explore solar charging options, please don't hesitate to reach out. Thank you for your continued trust in Outbound Power.
