Style: DELTA 2 Max 2048Wh
It's a great product for what it's designed to do: act as a nearly silent standby power source. It's powerful and well-built, but has too many features for it to be used as I intended. I purchased this mainly as an EPS backup for our sump pump. After using it for one day, I can say with a high level of certainty that it's not a good idea. 1) It does NOT act as a simple pass-through. While your grid power is ON, if anything goes wrong with the EcoFlow's configuration, or inverter failure, misc. electronic failure, etc., it will no longer pass the power through to your pump. Grid power ON + EcoFlow issues = flooded basement. 2) The unit has a manual power switch. Again, when the unit is powered off, power is not passed through. 3) The unit has an AC toggle switch (also in the app). If the AC is toggled OFF, power is not passed through. 4) There's a device timeout. If power isn't drawn during the timeout, then the EcoFlow will time out and not pass power through. It can be set to "Never Timeout". 5) There's an AC timeout. If AC power isn't drawn during the timeout, then the EcoFlow will time out and not pass power through. It can be set to "Never Timeout". 6) Firmware upgrades will cause the unit to revert to the default settings. There's a notice indicating this when you upgrade the firmware. This morning, I upgraded the firmware. After the upgrade, the AC was toggled OFF. OFF is the default. I recognized this within 30 minutes of the firmware upgrade (the sump pit was nearly full). I toggled the AC back ON, then the pump ran. What if they decide to push a firmware upgrade out automatically? I believe the timeouts were also reset to default, which is less than "Never Timeout". The question I asked myself was, "How reliable is our grid power?" My answer is about 99.999%. In 15 years, we've been without power for about 12 hours total. The final question is: how reliable is the EcoFlow? Given the five points above, it's certainly under 99.999%. I'm plugging the pump back into the wall.

I just received the DELTA 2 Max, and right out of the box it made a strong impression. The charging speed is the first thing that stood out to me. When I plugged it in for the first time, the percentage jumped so quickly that I actually double-checked the display. Getting to 80% in under an hour is not an exaggeration — it really does it. The overall build quality feels premium. The LFP battery chemistry was a major reason I chose this model, and even as a new owner, you can tell it’s designed for long-term durability. It gives a sense of confidence that you’re not buying something that will fade out after a handful of uses. I immediately tested it with several of my own devices — my computer setup, my monitor, some studio gear, a few household items — and it handled everything without even blinking. Seeing it push out clean power to multiple things at once reassures you that the 2400W rating is not just theory. The number of outlets also makes it practical; I never felt limited or cramped trying to plug in several items at the same time. The quiet operation is another pleasant surprise. When it’s charging, it’s barely noticeable. I had it sitting a few feet away, and it never became a distraction. The expandable capacity is also a smart feature. Even though I haven’t added extra batteries yet, just knowing that I can turn this into a much larger backup system if needed is a big plus. Overall, as a new owner, everything about this unit feels solid, fast, thoughtfully designed, and genuinely capable. It delivers exactly what I hoped for when I ordered it.

As an individual who frequently works on a sailboat, the need for a reliable, robust power source is paramount, and this power station has exceeded all my expectations. Firstly, its impressive 2400W output and 2048Wh capacity have been instrumental in running a variety of equipment. From power tools essential for boat repairs to lighting that extends my working hours, it handles everything with ease. Moreover, I’ve even used it to power a small heater, which speaks volumes about its versatility and power. The rapid charging feature is another highlight. Being able to fully charge the power station in just about an hour is incredible, especially when time is of the essence. This feature has saved me a lot of time and hassle, allowing me to focus more on my work and less on power management. Its portability is a huge advantage. Despite its high power output, it’s compact enough to be carried around easily, which is crucial for someone who is constantly moving around on a sailboat or outdoors. Lastly, the durability and build quality are top-notch, ensuring that this power station can withstand the challenging marine environment. It feels robust and reliable, which is essential for any equipment used in such settings.
