It has been a cold winter. My only source of heat is a Monitor heater. Although it runs on kerosene, the ignition and fan run on electricity. We have periodic power outages, so I have the Monitor hooked up to my Delta. When the power goes out, the Delta takes over and my house stays nice and warm. This is my second year with the Delta. I also have the EcoFlow River Max for my small space heater in the back of the house. Just received my second Delta so if the power is out for a long time I can keep the refrigerator running.

I just spent time comparing my ecoFlow Delta to another like sized unit I have from a well known manufacturer. The EcoFlow is smaller The EcoFlow has much better handles The EcoFlow display us inrivaled The EcoFlow charged fully in 2 hours vs 9 hours for the other unit. The EcoFlow is lighter. The EcoFlow doesn't require a HUGE external charge block I could go no but, you get the point! I'm ordering my 2nd unit to have two in my RV to go with my 4 100 AH AGM batteries and solar panels. I'll then run all my electronics through the EcoFlow operating as a UPS. I'm waiting to order the EcoFlow generator and might get the EcoFlow Pro.

I just received my Delta 1300. The build quality is excellent. It's operation is intuitive. I was able to charge it from 29% to 100% fully charged in approximately an hour. I like the protective bag that came with it but I do wish that it had an attached pouch to hold the cords. Overall I would rate it as excellent.

I received the delta unit last week as it took awhile to receive due to popularity ,the unit was packaged extremely well and looks very sturdy and made very well,also ordered the solar panels but will need another set as 1 set won't be enough to charge solar fast, the wall charge is extremely fast pushing 800 to 900 watts,the solar is only 92 watts so another set is required ordered the mc cables for additional panels. I keep the unit plugged into outlet when not in use per owners manual,2 Year's warranty for peace of mind,I researched hard on this product and canceled the blueetti to go with this purchase,so far very happy as only time will tell,Jeffrey from Wisconsin:)

I love it! My power went out in my apartment and the the Delta kept my food nice and cold in the fridge for 9hours and still was able to watch and charge up my laptop and cell phones. I charge it up every chance I get. Thank you to all those big brains who invented the delta!

Small but powerful! Bought this as a backup because we have threats of power outages due to heat, fire, and earthquakes. I wanted something small I could move myself but was powerful enough to keep our refrigerator going. I wanted batery and not gas so it could be used inside. The Delta 1300 is perfect in all respects.

I love this I really didn't think it would run my refrigerator....but it can and it can run it for 9 hours. I just love this machine. I would recommend this to anyone. I love the fact that even the cover is padded when you pick it up. It will run a coffee maker for 1 hour, and it seems to stay charged up even months later. I plan on using this to go off the grid this winter just as much as possible. Thanks EcoFlow!!

I own 2 Delta 1300s purchased Sept & Nov 2020. Giving it/them 4 stars, I'm fairly impressed with the relative small size, quality of (visible) materials & manufacturing (craftsmanship), display functionality and general functionality and performance. What could be better: 1) As I primarily use these outdoors (often on beach- on sand, close to water), I wish ALL electrical outlets had caps/covers (like the 12v "car" outlet, and like the electrical inputs) to protect from git and oxidation. (To keep my units grit and moisture-free when in use, I place them in sealable plastic storage bins prepared with drilled holes for cables and ventilation.) 2) Once unit is fully charged, I wish display would EXPLICITLY indicate full charge instead of "hanging" on "01" minute remaining (better to indicate "00," (no time remaining to charge) or "FULL." 3) Master/Slave mode: I wish master display would indicate the COMBINED TOTAL power remaining & time remaining of the SYSTEM (of the linked units). 4) Master/Slave mode: I wish the "swith-over" time from master to slave was faster. (Most of my audio/PA equipment is not effected by the switch; one unit turns off for a audible second or so.) 5) Manual could be better; it seems it's written by folks for whom English is not their first language; so, it's not always clear. Also, manual could be more explicit, eg.: While manual explains HOW to hook up units in master/slave mode, it does not inform user of the operational BEHAVIOR of units once operating in this mode; it would be nice to know -- in advance of use -- how each display will function, and how the system handles "paying out" power. 6) From my perspective, as a consumer, it's a shame the internal batteries are not replaceable once spent- It's not "green & clean," in fact, it's wasteful to dispose of an otherwise functional unit simply because the internal batteries are spent; surely this is not cost-effective to the consumer. All said, I'm fairly pleased with my 2 Delta 1300s this far.

We made this purchase after researching several options. We camp and this will be an opportunity not to use a gas generator. Occasionally we have power outages so this will put us at ease. Haven't had the opportunity to use it just had but we are very optimistic ?

very versatile machine. unbelievably easy to use. this unit will save me a 100 mile round trip that accompanies power outages where I live. overall I give this unit an A+ and I speak with previous experience with battery components for IT and GPS satellites. not to mention besides powering my BIPAP machine you can hook up refrigerators or whatever!
