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. Review: Great Backup Power Station - I bought the Eco-flow Delta 2 Max power station a couple of weeks a go and I am completely satisfied with my purchase. The unit is very well designed and a solid build build. It's very easy to setup and charge. In fact the fast charging feature allows you to fully charge the batteries in under two hours when plugged in to a wall outlet. There is an excellent app that you can download from the Apple App store. The app gives you up to the minute information as to the status of the device. You can see when it's charging and adjust rate. You can also see the wattage of of a connected device drawing down the battery as well as an estimate of how long the battery will last at a given rate. You can monitor the device remotely using the app even when you are out of town. I also like the 10 year battery life of the LFP batteries and the 3,000 charging cycles as compared to other similar devices. The device weighs in at about 50 lbs which is not light but easily manageable. We have a lot of power outages in my area and my main reason for the purchase was for backup power for our refrigerator and wifi modem and router. I tested it on our Samsung refrigerator and could monitor the discharge rate and time. It worked beautifully and will help us avoid losing a lot of food from our fridge and freezer in the future when there is a power outage. Overall, this was an excellent purchase. I like the company and the support they provide on their website. I also purchased the solar panels to go with it for times of extended emergency power failures. ## Features - Fuel up 80% in Only 43 Mins: With DELTA 2 Max's upgraded tech, combine up to 1000W solar input with AC for world-leading charging speeds.

If you don't know the answer, please do not reply. Thank you.** A: As far as I know yes, it is pure sine wave. **Q: Can it be connected to a car cigarette light? And if so how long do you think it'll take to reach full charge?** A: I have a Tesla model y Long range and I have mine connected to the rear 12 volt “cigarette” jack. On my vehicle it puts 111 watts of power into the ecoflow so the answer to how long, depends on how much do you need. If you used up 1000 watts hours or about 1/2 it would take about 10 hours to refill it. The amount of energy will vary for each type of vehicle but the eco flow will tell you how much and how long to charge in those particular conditions. **Q: When using extra battery with power station can you continue charging the extra battery when power station reaches 100%** A: Yes but mine stay close to the same percentage and seem to hit 100 percent around the same time. **Q: Can you input from a powerwall battery? I have some 5kw server rack lifepo batteries. Can they feed juice to the delta max 2 to run appliancsz** A: Yes , with the right adapter ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's a great product, just not as an EPS (always connected Emergency Power Supply) *by C***H on March 28, 2026* It's a great product for what it's designed to do: act as a nearly silent standby power source.
