In the comment section of these videos, I’d often hear about another lithium power station maker called EcoFlow. Several people even asked if I could do a review of one. So when EcoFlow contacted me recently asking if I would like to test out their Delta Max power station, I replied yes. The specs look fantastic, and I was interested to see why there is a good buzz around their products.
For the EcoFlow, I’m planning, as I did for the Bluetti AC200P and the Lion Energy Safari ME, to split the review into three videos. First, up will be the intro and features, then an in-depth video testing the power station charge/discharge and power capacities. And third, a real-world review using it as we boondock around the USA desert southwest this winter.
EcoFlow Delta Max Review PT1 – Introduction and Features
PT 2 – In-Depth Demos and Tests + 400W Solar Panel
In this second of a three video review, I perform in-depth testing/demos of the EcoFlow Delta Max portable power station. First, I test the battery capacity using the AC inverter output. Then I try a fast charge test using my 2000W gas generator for power. Next, I try to power multiple appliances in our RV, including our 13K BTU air conditioner. The video finishes with a brief look at EcoFlow’s 400 watts folding solar panel and a pair of solar charging tests.
After several weeks of dry camping tests, I’m pleased with the Delta Max’s performance and ease of use. Stay tuned for a third video next month, where I’ll give my final impressions and a complete list of pros and cons as I see them.
Pt3 (Conclusion) Likes & Dislikes after 2 Months of Boondocking
In this video, I’m back after two months of off-grid camping with the EcoFlow Delta Max portable lithium power station and the EcoFlow 400W folding solar panel. I go through all my pros and a few cons as I see them for this power station. Overall I’m pleased with the performance of the Delta Max and now consider it my favorite portable power station that I have ever tested.

Update: (EPS 30MS vs. UPS) Causes Power Glitch for iMac and Starlink
Just a quick review update for the EcoFlow Delta MAX portable lithium power station. I’ve discovered a minor glitch to it that showed up while I was boondocking this past week. Its EPS “Emergency Power Source” functionality has a 30 milliseconds delay. This is long enough for our iMac computer and Starlink Internet Dish system to reboot when I power off my generator after recharging.
