Luckily, I’ve had a chance to try out and review several portable lithium power stations throughout the last couple of years. I’ve tested various Jackery, Himcen, Bluetti, and Lion Energy offerings.

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.
