Finally a product that performs as advertised. Bought my first Delta Pro in March ‘22 and it is solidly constructed using quality parts and cutting edge technology. Purchased mainly for temporary backup power during brief power failures. My Delta Pro charged quickly upon receipt and performed perfectly during a recent outage powering my Fridge, freezer, tv, lights, 2 pellet stoves and even my garage door openers. I’ve also power my paint sprayer, pool pump, and power tools in the field. So pleased I purchased a second Delta Pro and a Double Voltage Hub so I can connect to my transfer switch as I begin to build out a whole home backup system. 5 STARS all the way.

I was excited for this product. Basically, it is the modularity that makes it a winner. Since, owning it, i have had multiple situations in which it has come handy. Took it camping with the tow hauler, GTG. A plane crash locally and caused a power outage, back up power GTG. Helped a bud with a project with no AC power: no problem as external power was GTG. Attached 1200W of solar panels , GTG.
I do have a few gripes that do not impact my overall rating: (1) cable between Delta Pro and extra battery should be a tad bit longer, (2) USB plugs on extra battery (or a connector, similar to the generator connector, that had usb/12volt/etc.) would be great, (3) better instructions for setting up the Smart Home Panel. These gripes are minor and can easily be implemented/updated in the future.
Since getting the smart home panel, it has made it super easy to configure circuits in the house (I keep the network and garage refrigerator on battery back up and other circuits (lights and kitchen items) ready to easily switch), I can easily move the Delta Pro while not disturbing other items plugged in (before the smart home panel, my network would kill all firmware and software updates when the network dropped), and have confidence of a battery back up solution.
All of this is due to the Delta Pro, its modularity, and mobility.
Usage of this item will be based on your lifestyle and need. It's tremendous as a power back up solution. It pretty good for off grid and or camping (limitations due to weight). I would ( and have) recommended this product and ancillary components to others.

GTG - Tri

We've been wanting portable batteries for a long time so we purchased two Delta Pros to run our 240V pump, once we receive the Double Voltage Hub - due tomorrow, and to act as back-up during CA Public Safety Shut-offs and winter storms. With a L14-30 cable we will connect directly to our manual transfer switch to run the house.
Recharging the unit can be set from 200W - 1800W AC but I haven't tried the fast charge yet. To stop charging before fully recharged you must disconnect the AC plug. Note also that you need to unplug the AC to the unit to turn off the Delta Pro. EcoFlow recommends you do not leave the unit(s) plugged in all the time as this may cause degradation of the battery over time.
This 70 year old is able to wheel the Delta Pro around - portable but a bit heavy at ~100 lbs. My husband and I can lift it into the SUV and take it on trips. Solar panels are on the way. The fan is a little noisier than I expected when recharging, but not bad. Delta Pros are a great value for the price!

The DP really is excellent for Vanlife. I'm using it connected to a 760W solar array on the roof and a additional 500W inverter to charge via the cars alternator. The option to charge with solar and AC therefore is just ideal. As I'm using a normal AC fridge and the idle draw of the inverter is quite high i added a small inverter to the Anderson port to reduce losses. This setup is perfect for me with my inductive cooking plate!

We purchased the Delta Pro and extra battery last winter as a backer on Kickstarter. We initially planned to use this device as a backup in case we lost power to our home. I work from home and need to have internet and power to my home office at all times. We recently lost power for four hours and the battery handled all of my home office equipment as well as other appliances in the home with ease. Since these are portable, we plan to use these on our next camping trip along with a 300w solar panel. Highly recommend the Delta Pro.

I originally bought the Delta for my van conversion but quickly realized that I needed greater DC output than it would provide for my 2 high power DC uses-diesel heater and water pump. I ended up replacing the Delta for the Delta Pro which allows for 30 amp output DC. Love, love , love it. (even though it may be a bit overkill for my little van). Setup was so easy with an Anderson plug to the fuse box and charging is fast through an AC outlet. The Delta Pro is a bit of a beast though and difficult to load in and out of the van as it weighs about 100 lbs. The app is really helpful in monitoring the usage as I have trouble moving it around in the tight space to see the display.
