This battery is perfect works great long run times I use it to run a paint sprayer on in remote locations run saws recharger batteries and lights for my tool shed and a coffee pot ran my refrigerator for 6 hours when the lights went out I will buy another

I bought this along with a set of solar panels to power a powerful laptop, cameras, drone and laser scanner on a very remote job site in Death Valley. It worked great and I never got close to running out of juice. I've powered an entire wedding (two 40' tents with lighting, as well as a sound system and a band) with it! It gave me an 8 hour run time for that. However, you should know that in cold weather, like with all lithium batteries, it's performance is severely impacted. I've tried to use it in an off grid cabin while plugged into the solar panels but it will not take a charge from the panels when it is cold out. If it is charged to 100%, but cold, I get a very short use cycle before it dies. If you are planning to use a battery generator in cold weather you'll have to work out a way to keep the unit warm. I've thought about trying to put it into a cooler with a couple of hand warmer packs, but I haven't tested that yet.

A very functional Easy to Use unit. It charges quickly with two 100 watt solar panels in series, the mppt charge controller usually gets 180 or better watts in on a sunny day. The inverter has no problem outputting 1400 watts to charge my Nissan Leaf ( I usually only charge in 'steps' of .25 to .5 kw at a time keeping the Delta 1300 charge between 35% and 90% ). It has no problem powering an induction cook-top or microwave. The display is clear and bright with all the necessary information you need. Am very happy with this unit ! ! RH

Just used it for Hurricane Zeta - 5 th storm to hit Louisiana this year. Relied on it as our sole source of power for about 5 hours. Used it to keep phones and flashlights charged and ready then a fan and usb powered light. We were at about 65% battery life or about 6 hours running the fan and light. Used a rice cooker to warm up some food and it handled it no problem. Have solar panels to charge in about 4 hours but planned or finding a 110 current to charge in an hour Very portable and easy to use. Seems you need to know it's limits however as there are stern warnings about getting the batteries wet or overheated.

We love this thing! Bought it to power our bus conversion but we have used it routinely at our home now for powering everything from the instant pot to an air compressor to a paint sprayer to our house water pump! Super impressed... technology is outstanding. The fact that it can recharge so quickly from the house power is AMAZING. It's very user friendly, hooking it up to a car or the solar panels is a piece of cake. Would definitely recommend.

This baby is the ultimate portable Beast! Pretty easy to put into the back of your car or even onto a bike basket to take to the beach to power a DJ party. I also like that it charges quite fast, and you can also use it while it's charging. I have not encountered any problems with the one I've gotten recently.

Bought the EcoFlow Delta 1300 as a remote power supply for my work. It has the highest surge and operating for its size of any portable power bank I looked at. All others were too large, too heavy, or low power for AC. It runs my large fan with inrush as high as 21A with no problem. The Lithium Ion battery will give very limited life. It charges fast(almost too fast on AC), is lightweight, powers most AC appliances that can plug into a 15A outlet, and has other charging options. It would not run my HF air compressor with 20gal tank though. Look at other online reviews so you understand the limitations of the product. If it used LiFePO4 battery it would have twice the expected life. My first unit had a defective MPPT charge controller and would not charge correctly from a 12V power supply or vehicle. I contacted EcoFlow CS and was instructed to provide a video of the problem. The unit was deemed defective and I was sent a return label. Keep your box with the Hazmat labels as FedEx does not always have them. I was not happy with the two week turn around time. The replacement works as it should. Overall, I am satisfied with the unit as it meets the needs for which I purchased it. Customer service was responsive, but could use a better method to upload videos.

Great Item! Perfect for just about all power needs. Great for back up for recharging special needs medical equipment CPAP, Feed pumps, etc. Great to keep Routers and Modems up and running, If you got power you should have internet. Power tools, microwaves, the list is endless. Use in conjunction to complement small gas generators for recharging.

My unit was a lemon and didn't work out of the box. When I contacted Ecoflow support with video of the inoperable unit, they chose to ghost me. Based on the hype around this product, I assumed this would be good purchase. I was so wrong! Inferior product and horrible customer service. Suggest you look elsewhere- I have found much better. Wish I had done more extensive research prior to this purchase.

It charged up the battery last night and used it today. Battery was at 100%, I use it on my fridge and after 3 1/2 hours the battery was down to 36%. Everything works great. I recharged the battery again in only 45 minutes. Only thing I would changed would a way to add more batteries.. So far it a Great solar generator !!!
