I recently acquired the EF ECOFLOW Portable Power Station DELTA 2 Max and it has been nothing short of a game-changer for my sailboat maintenance and outdoor adventures. 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.

In conclusion, the EF ECOFLOW Portable Power Station DELTA 2 Max is an outstanding product that I highly recommend. It’s a perfect fit for anyone in need of a powerful, fast-charging, and durable power source for outdoor activities or marine use. A solid 5-star rating from me!

So, two parts:
1: The Echo Flow Delta 2 Max
I had initially just gotten this to be the power station for my camp setup. But thinking about it, it's a lot more than that. It can be used to recharge my RC batteries while at the RC field. It can power appliances at home. If you need to power a light system for the backyard. Power a projector and laptop while out at the park. It's portable power...

This is 50 lbs. It is heavy. But the handles are sturdy. Packing it into my SUV I can put things on top of the station and it won't slide off. The handles are study, if this is the only thing you are carrying at the moment, no problem. For the amount of power it stores, 50 lbs is about right. 85" TV and 350W speaker bar/sub 13 hrs run time. Yeah, I like this thing!

2: The Echo Flow 400W Solar Panel
So, in full sun light, if you line it up to the sun exactly, I get about 389W of power coming through. to line it up close to what's needed to get max wattage, get the Solar Angle Guide. Changing the angle with the Solar Angle Guide 10 degrees, increased output from 326W to 384W. Well in that particular instance. In the evening shade, no direct sun light, I was getting about 36W of power. I've only completed one full charge during various times of the day. So I can't give you an exact how long it'd take from 30% or less with good sun light to charge with this panel. But I would say about 9hrs at least for a 70% charge? I need to play around with the charging more to a have a better idea on how long and what level of sun light.

Bought the ecoflow delta 2 max for power for my vendor tent at live events. Have only tested at home so far but I will be taking it to a 2 day festival next week and I think it will do great. Charges crazy fast through AC outlet. Charging with solar panel is obviously slower charging but it does charge up just fine. AC outlet will charge it with like 1650 watts and gets to 100% in a bit over an hour. With the 220w solar panel I got, I set it to charge from 60% and it said about 11 hours till full, but I also don't think my panel was at an optimal angle because it was only outputting about 150w. Love how the panels fold up into the case, very portable, and for the most part I feel like the case offers some good protection during transport.

Performance is impressive, for what I need it for. I need to run 1 3d printer on display, lights, charging for my phone and other electronics of course.
at 100% charge, I ran 1 of my 3d printers off of it for over 11 hours and the battery was only 60%. I think this setup will work PERFECTLY for a vendor booth. This is going to make my setup really pop.
