    I bought this unit for two reasons: 1. Power for a remote toolshed for lighting and powering tools. 2. As a backup power source in case of outages.For #1 drills, sawz-all, shop-vac and lights work just fine. Large circular saw did not and I knew that would be iffy. Just keep in mind the watt hour limit of the battery. Nice readouts for power consumption. Do the math and you have a pretty good idea of how long it will last.For #2 haven’t tried the fridge in kitchen but the dorm style fridge works just fine. Definitely enough to power a cale modem and router. Even during Superstorm Sandy there was no power but cable was working. Go figure. It isn’t enough to power a house or large appliances but other creature comforts are covered. At least there are options.The unit is heavy but that was expected. Remarkably compact too. No surprises there. An additional feature that maybe i missed is a cover for the unit. It looks like its water resistant or proof. I guess so it can be left out doors. Not sure I’d do that. Plpus there are slots to handle the grounding prong on three prong plugs.The three methods of charging are great. I tried the wall outlet and soalr panel. Haven’t tried the cr lighter option yet.May seem expensive but its like insurance. When you need it you’ll be glad to have it.

     I’m using two 100w flexible solar panel with it and at a cloudy day it takes in about 120w and max out at 180w of power!!! It is astonishing that it can also run my table saw and miter saw with 1800w output! What a monster! This is by far the most powerful power bank I own.I plan to mount those panels on my roof so I can use the power bank in my office. Please click helpful if you find my review useful. Thanks!

    Do your research on youtube.. most everything published is spot on. The only things I saw where people had a problem was covered in the manual or faq. The unit has more safeties on it and it keeps you from making mistakes. Sometimes this was reviewed as a flaw … and it truly wasnt in my opinion. Example.. It actually does easily charge from zero to full in about an hour and half. What it does not do is immediately after you do a heavy discharge charge back this quickly. This is a protection circuit kicking in and throttling back the charge rate to half.. in order not to overheat the unit. It gradually increases as the unit cools. Even so.. it charges faster than anything I have ever seen. One thing pointed out and I agree is the stated capacity is actually about 1000 vs what is advertised. HOWEVER, if push came to shove, the battery is probably exactly as advertised. What I am referring to is what I can actually get out of it. I am a picky anal geek that is seldom satisfied. This fits the niche of if you want to wait till the last minute for a weekend get away, throw the charger on house charge whild you are packing and gasing up.. it will be 100% ready to go. NO looking for inverter.. no looking for cables.. no looking for extra fuses.. etc etc. Grab it and go and plug in.. If I were younger I woud try and sell the things.. Hope this helps. I hate putting crap reviews or reviews that are “paid for” by the manufacturer etc and then being disappointed. I certainly am please..

    It does everything as advised, charges off my one panel (270 Watt, 24 volt Renergy) in about 3 hours in full sun. It will also power all my garage power tools and will run my huge fridge for 15 hours. Tested it. Will pack it for my Army field TDY’s.

    I was looking for a portable battery that could handle 15A power tools so I could use a lawn vacuum and pressure washer in places that were too far away from an electrical outlet. I was getting frustrated having to unwind and wind increasingly longer extension cords and make sure they didn’t fall into the pool. I also wanted to have something I could hook up to a solar panel and keep as an emergency backup power source. I looked into a couple of options like Ego Nexus (no solar input) and Goal Zero (never in stock). I saw that the Ecoflow had good reviews and bought it.It took almost a month to get to me due to the shipping company losing it. Customer support was great, though, and they of a replacement unit. They were very friendly. I’ve only had the unit for a couple weeks, but it’s done everything I’ve asked of it. It runs all my high amp power tools, even the 15A ones. I hooked it up to a 110w solar panel, and now I’m charging all my battery powered garden tools like my lawnmower, string trimmer, blower, and hedge trimmer off grid!The packaging was excellent, and it comes with all the cords you will need, including a car charger and a solar connector. While not light, the handles provide for a sturdy grip so you can carry it anywhere. The display easily tells you time remaining to charge, input, output, and charge level. I do wish that all the AC and DC outlets were on the same side of the unit, but that’s minor.Overall it’s an excellent battery at an attractive price.

    Recently picked up the Delta and was super skeptical about it because of its bold claims, long warranty, and the price tag being over $1,000. I can say over the past few weeks of using this Power Station, it was totally worth the cost. Here have been my use cases and how the Station has done. Btw, as I’m typing this review, my video editing desktop setup is plugged into the Delta, running at full speed ;)Also before I talk about the use and functionality of this Power Station, can we talk about the boxing?! EF ECOFLOW really impressed me with the boxing of this product. When you receive it, it looks exactly how Apple would box their products. Once you get the box open, there’s more than enough custom molded foam to keep the Power Station, its instructions, and accessories all safe. Look for this in my video review coming soon 😉Now onto using the Power Station!A full campsite Power Source, enabling Glamping at its finest. The main reason why I’ve gotten into these portable power stations is that during Coachella last year, someone in our group had brought a smaller unit and used it to blow up our mattresses, charge our phones, and camera batteries, and it worked the entire weekend. It did recharge during the day with a solar panel, and I was damn impressed. I tried these smaller units myself, but I guess I’m a bit more glampy with my needs.Test #1 – Setting up a full campsite in my bedroom to get an idea for what my campsite will look like once we’re all able to get outdoors and go camping again (damn you COVID19). This Station effortlessly powered some Edison bulbs, a projector, two MacBook Pros, air pump, two smartphones, Sony a7iii battery charger, 42” 4K TV, and an Nvidia Shield. This was after using the Power Station for some photo lights I used to light the room extra bright (to really stress test this unit) while setting everything up.This Power Station powered everything flawlessly! We had it hooked up to most the items listed above all night long, and when we woke up, still had enough juice to fire up my hot water kettle and make a French Press full of coffee. I would say Test #1 was a huge success.Test #2 – Working on photo/video projects anywhere I want. I’ve always had the dream of #vanlife, but I’ve never pulled the trigger. So, in a way to emulate it, I’ve always wanted to setup my editing desk in a scenic spot, looking over an ocean, lake, or some mountains. With the Delta, I had to give this a go. As you’ll see in my video, the location was stunning, the weather beautiful, and my entire editing setup was being powered by a battery! This was just a dream, and the Delta enabled me to make it happen. I worked outside for about three hours, then packed up and headed home. The Delta had only used about 20% of its charge.Test #3 – Recharging from the wall outlet and a solar panel. This unit can indeed go from a few % charge to 80% in an hour when plugging into the wall. When I first plugged it in, I thought it was going to take hours. Fast forward 30 minutes, and this thing had steam rolled through the 40% mark and was damn near 50%. It took just about an hour twenty to full recharge this station.Solar Panel recharging time. I have a 60w solar panel from another brand and seeing that with an adapter (not included) I was able to run it, I did. The panel is supposed to be able to charge at 60W, but in reality it gets closer to 25-30W. Because of this, even after a full morning and afternoon, I was not able to get to a full charge, but it was exciting to see that I could recharge from solar at all, especially with a different branded panel. If you’re going to go this route, get a significantly bigger panel, or just concede that solar will just stretch your charge out.After all this praise, I think its important that I touch on the negative pieces of this unit. Two things come to mind. One is the weight, but it’s kind of expected when you can carry around this much juice in a well-constructed unit. For me it’s totally fine, but for my girlfriend who is smaller, it’s tough for her to move around.The other item is the fan sound. This Power Station does have some pretty aggressive cooling fans that kick on under heavy load or when charging. With the amount of electricity pumping in and out of this station, I kind of understand it, but I’m sure some clever engineer could solve this problem, maybe install larger slower moving fans?All in all, this is a very happy purchase, and I’m excited to get my test video live later this week!

    I ran a line from the ECOFLOW 1300 to my RV Refrigerator/Freezer. I took off the external Refrigerator/Freezer cover. At the stud where the AC power outlet is, I drilled a hole in the stud. I used an extension cord with 14 gauge wire. I cut off the male end and pushed the wire into the hole. Now there is the female end of the cord just under the AC outlet. I just unplug the Refrigerator/Freezer from the AC outlet and plug into the female end of the cord. The exit location is in the cabinet under the oven. Your location may vary. I purchased a male 120 inlet and mounted it under the refrigerator. I could then run a cord from the ECOFLOW to the inlet. It will power your unit for about 4 hours before depleting the batteries. I recently made a 9 hour trip using this device. After disconnecting from shore power, I turned off the Refrigerator/Freezer. I then travelled for 1.5 hours. Stopped and turned on the Refrigerator/Freezer for 1.5 hours. I alternated in this pattern for the whole trip. When I got to my destination, everything in the freezer was frozen and the refrigerator was cold. I also had a 12 V cord plugged into the RV and then into the 12 V inlet of the Eco/Flow. This allows your 12 V system to recharge/maintain the EcoFlow while the it is providing AC, although it is very slow, it does help a little.
