What’s in the Package
Before you get started with the setup, take a moment to make sure everything has arrived. The EcoFlow Delta Pro comes with a specific set of components, and understanding what each one is for will save you time later on.
Here’s what you’ll find in the box when you purchase the EcoFlow Delta:
- The Delta Pro Unit: This is the main power station.
- The User Manual & Warranty Card: It’s worth reading this for safety instructions.
- An AC Charging Cable: You’ll use this for wall outlet charging.
- A Car Charging Cable: This is for 12V vehicle charging.
- A DC5521 to DC5525 Cable: You’ll use this for compatible DC devices.
- A Handle Cover: This protects the handle during transport.
Accessories like the EcoFlow 160W Portable Solar Panel, Smart Generator, and Extra Battery are sold separately. You can add these as your setup grows. If you ordered a bundle, double-check your packing list against what’s in the box before you get started.
Charging the EcoFlow Delta for the First Time
Your Delta Pro will probably arrive with some charge already in it. However, EcoFlow suggests that you fully charge it before using it for the first time. This will calibrate the battery management system and ensure that the battery readings displayed on the LCD screen are accurate right from the start.
There are three primary methods to charge the Delta Pro, and each one is ideal for a different scenario.
Charging with an AC Wall Outlet
This method is the quickest and easiest. Plug the AC charging cable that comes with the Delta Pro into the input port, then into a regular wall outlet. One key point: your wall outlet needs to supply more than 15A of current. If it doesn’t, you’ll have to slow down the charging speed with the AC Charge Speed Switch on the back of the unit, or you could trip a breaker. You can also adjust the charging power through the EcoFlow app once your unit is connected.
Charging with Solar Panels
The EcoFlow Delta is a real standout when it comes to green energy, as it can be charged using solar power. The Delta Pro model can handle up to 1,600W of solar input, which makes it one of the top-ranking portable stations for solar power input. You can hook up suitable panels, such as the EcoFlow 160W Portable Solar Panel, straight into the solar input port on the device.
Here are some tips for effective solar charging:
- Place the panels at a right angle to the sunlight for the highest output
- Ensure that no part of the panel is shaded — even a little shading can greatly reduce output
- The Delta Pro can handle up to 1,600W PV input with a DC voltage range of 11–150V
- You can connect several panels in series or parallel depending on your configuration
- Charging doesn’t stop completely in cloudy conditions, although output is reduced
On a sunny day with the panels positioned perfectly, the Delta Pro can charge from 0% to 100% in about 5.6 hours using only solar power — which is quite impressive for a 3,600Wh battery.
Charging with a Car via the 12V Input
The car charging cable that comes with the package can be connected to the 12V cigarette lighter socket of your car. This method is a bit slower, usually providing about 12.5V/8A, but it’s handy if you’re traveling and need to recharge the battery in between uses. It’s best to use this as a backup charging method rather than the main one.
How Much Time Does it Take to Fully Charge
The time it takes to fully charge the Delta Pro can differ greatly depending on the method you use. If you’re using a standard outlet for AC wall charging, it will take roughly 1.8 hours to reach full charge. This is one of the fastest charging times in its category, and it’s all thanks to EcoFlow’s unique X-Stream charging technology.
Understanding the LCD Display
The LCD screen on the EcoFlow Delta Pro is your command center. It displays battery percentage, input wattage (the speed of charging), output wattage (the amount of power being drawn), and the estimated time to full charge or depletion — all in real time. You don’t need the app to get this information; the screen provides all the details you need to make quick decisions about power management.
Here’s what you’ll find on the EcoFlow Delta’s display:
- Battery percentage — This large number in the middle of the display shows you how much battery you have left.
- Input wattage — This shows you how fast the battery is charging from any active sources.
- Output wattage — This is the total amount of power being drawn from all the active output ports combined.
- Time remaining — This gives you an estimate of how long until the battery is fully charged or fully discharged.
- Active ports — These indicators show you which types of output are currently enabled.
When you turn on the unit, the display will automatically activate and stay on while you’re using it. The display is bright enough to read even in direct sunlight, which is important when you’re using the Delta Pro outside.
For more detailed information, such as usage by port or past usage, you’ll need to use the EcoFlow app. The LCD provides basic information, while the app provides all other information.
X-Boost: Power High-Wattage Devices Without Overloading the System
One of the most exciting features of the EcoFlow Delta Pro is X-Boost, and it’s easy to see why. It addresses a common issue that plagues most portable power stations — the strict wattage limit that renders certain appliances unusable.
The Role of X-Boost
X-Boost is a smart power management technology developed by EcoFlow. It enables the Delta Pro to power devices that require up to 4,500W, despite the fact that its AC output is rated for 3,600W. It accomplishes this by cleverly controlling the voltage and current provided to the device. This effectively “fools” appliances that draw a lot of power into operating at a lower, sustainable wattage. This prevents them from being damaged or causing the system to shut down. It’s not about pushing the hardware beyond its limits, it’s about delivering power in a smarter way.
What Devices Are Best Suited for X-Boost?
X-Boost is perfect for devices that have high startup draw but don’t require full rated wattage to operate. Examples include hair dryers, electric grills, space heaters, angle grinders, and air compressors. These devices often cause portable power stations to display a fault error, but the Delta Pro can handle them with ease when X-Boost is enabled.
Setting Up the EcoFlow App
You can download the EcoFlow app on either an iOS or Android device. Once you have the app, you can connect it to your Delta Pro, turning it into a power management system that you can control right from your phone. You can check usage, change settings, and even control the Delta Pro remotely.
Setting up Wi-Fi and Bluetooth on the Delta
First, download the EcoFlow app and set up a free account. Then, turn on your Delta Pro. Open the app and click on “Add Device.” The app will look for EcoFlow devices close by using Bluetooth. Ensure your phone’s Bluetooth is turned on and you’re close to the device when you first connect.
After you’ve paired the Delta Pro with your device using Bluetooth, you can then connect it to your home’s Wi-Fi network using the app. This allows you to monitor it remotely even when you’re not in the same location as the unit. If you’re using the Delta Pro off-grid and don’t have Wi-Fi, you can still use all of the app’s features within range using Bluetooth.
Keeping an Eye on Battery and Output from Anywhere
Once you’re all set up, the app dashboard will give you a live look at everything your Delta Pro is doing. You’ll be able to see how much battery is left, how much charging input it’s getting, how much total output is being drawn, and which ports are currently in use. You’ll also get a real-time breakdown of power consumption that you can’t get from just the LCD screen. This includes data for each individual port and a usage history over time.
It’s particularly handy in home backup situations where the Delta Pro may be operating in a different room or garage. You don’t have to walk over to look at the LCD, a quick look at the app will tell you exactly how much runtime is left based on current usage.
Modifying Charging Speed and Settings
With the help of the app, you can determine the top AC charging speed, which is handy if you’re on a circuit that can’t manage full draw. You can also schedule charging times, set a top charge level (some users like to keep it at 80% for prolonged battery life), and arrange X-Boost and EPS mode settings without needing to touch the unit itself.
EPS Mode: Automatic Backup Power When the Power Goes Out
EPS is short for Emergency Power Supply, and it’s one of the Delta Pro’s most useful features for home use. When EPS mode is turned on and the device is connected to your home’s circuit with the correct adapter, it keeps an eye on grid power all the time. The Delta Pro switches to battery power in less than 30 milliseconds as soon as grid power goes down — so quickly that most electronics, including sensitive devices like desktop computers and medical equipment, don’t even notice the interruption. Standard UPS (Uninterruptible Power Supply) devices usually switch in 20–30 milliseconds, so the Delta Pro is on par with dedicated backup hardware but much less complicated.
Increasing the Capacity of the EcoFlow Delta
EcoFlow made a brilliant choice with the Delta Pro by making it expandable. You are not restricted to the basic 3,600Wh capacity — the system is designed to evolve with your power needs over time, whether that means increasing storage or scaling up for whole-home backup.
Connecting Additional Batteries
You can attach up to two Smart Extra Batteries to the EcoFlow Delta Pro, each of which will add another 3,600Wh of capacity. This means that when fully expanded, the setup can have up to 10,800Wh of capacity — enough to keep a typical house powered during a multi-day power cut. The additional batteries are connected via a special port on the side of the main unit, and are automatically detected, with the total capacity displayed on both the LCD and in the app.
Unlike traditional batteries, the Smart Extra Battery does more than just store energy. It communicates with the main Delta Pro unit to intelligently balance the charge and discharge across the entire system. This feature prevents one battery from draining while another remains full. It’s this type of detail that distinguishes a well-engineered system from a basic power bank with extra cells attached.
Connecting Two EcoFlow Delta Units
The Delta Pro also allows for two units to be connected together. This doubles your AC output to 7,200W and your capacity to 7,200Wh before you add any additional batteries. This is done using a Double Voltage Hub accessory (available for US and Canada), which connects both units and allows them to work together as a single, unified power system. This is a real game-changer for anyone using power-hungry appliances like electric dryers, EV chargers, or workshop equipment, something that most portable power stations simply can’t match.
How to Keep Your EcoFlow Delta in Good Shape
Keeping your Delta Pro in good condition isn’t hard, but a few simple routines can greatly extend the life of the battery. The Delta Pro uses a high-quality LFP (Lithium Iron Phosphate) battery, which is naturally more stable and durable than standard lithium-ion cells — but it still benefits from good maintenance.
Best Storage Temperature and Conditions
Store your EcoFlow Delta Pro in a dry area with temperatures ranging from -20°C to 45°C (-4°F to 113°F). If you’re not going to use the unit for several weeks or months, EcoFlow suggests keeping the battery charged between 30% and 60%. Storing it fully charged or fully drained for long periods speeds up battery degradation. Don’t expose it to direct sunlight during storage and keep it away from moisture — the Delta Pro isn’t waterproof.
How Frequently Should You Charge and Discharge for Battery Health
For everyday users, you don’t need to drain the battery completely before recharging — this is an outdated practice from the days of nickel-cadmium batteries that doesn’t apply to LFP chemistry. The Delta Pro’s battery management system takes care of most of the hard work automatically. However, EcoFlow suggests performing a full charge and discharge cycle approximately once every three months if the device is in storage, to maintain the cells balanced and the battery percentage reading accurate. Daily users don’t need to worry about this — regular use is actually beneficial for LFP battery health.
When using the app to set a maximum charge level, it’s a good idea to aim for 80–90% for daily use if you’re interested in prolonging the life of your unit. While the difference in usable capacity is minor, the decrease in battery stress over hundreds of cycles can significantly increase the lifespan of the unit.

Common Questions
Even after going through the setup process, it’s completely normal to still have a few questions. The EcoFlow Delta Pro is a feature-rich device, and it can be a bit overwhelming at first. Here are some of the most frequently asked questions from beginners.
Is it possible for the EcoFlow Delta to charge and discharge simultaneously?
Indeed. The EcoFlow Delta Pro has the ability to charge and discharge at the same time, so you can keep your devices powered while the unit is charging via AC, solar, or car input. This is referred to as pass-through charging, and it functions smoothly without any manual switching or setup. Just remember to keep an eye on the total wattage — your charging input and output draw are controlled automatically, but if you have a high output load and are charging via AC, the total charging time will be longer.
How many appliances can the EcoFlow Delta power simultaneously?
The Delta Pro comes with a total of 15 output ports: 5 AC outlets, 2 USB-C ports, 4 USB-A ports (2 standard, 2 fast charge), 2 DC5521 ports, 1 car power output, and 1 Anderson port. All of these can be used at the same time. The number of devices is not the limiting factor, but the total wattage draw is. The system runs smoothly as long as the combined load does not exceed the 3,600W AC output limit (or 4,500W with X-Boost).
Can I use the EcoFlow Delta indoors?
Indeed, the EcoFlow Delta Pro can be safely used indoors. Unlike generators that run on gasoline, it doesn’t produce any emissions while it’s running, so it’s perfectly safe to operate it inside your house, garage, recreational vehicle, or any other enclosed space. There are no fumes, no combustion, and no risk of carbon monoxide.
During heavy use or fast charging, it’s normal for the Delta Pro to get a bit hot. The unit’s internal cooling fans handle this heat. When the system is working hard, you’ll hear the fans spinning — this is a sign that everything is working as it should, not a sign of an issue. To allow for proper airflow, make sure the vents on the unit are not blocked during operation.
Here’s a quick guide for indoor safety:

Is it possible to bring the EcoFlow Delta on an airplane?
Unfortunately, you cannot bring the EcoFlow Delta Pro on a commercial airplane, whether as a carry-on or checked luggage. This is a common aviation rule that applies to all lithium-ion and LFP batteries that are over 100Wh. The Delta Pro’s capacity of 3,600Wh greatly surpasses the FAA’s limit of 160Wh per battery for passenger flights.
The smaller models in the EcoFlow Delta lineup, including the original EcoFlow Delta at 1,260Wh and the EcoFlow Delta Mini at 882Wh, are too large to be approved for flight. So, none of the Delta series units can be taken on a plane. If you need portable power for air travel, you’ll need a much smaller battery pack that falls within the 100Wh limit (or up to 160Wh with airline pre-approval).
The Delta Pro is easily portable by land, whether by car, truck, RV, or boat. It’s compact enough to fit in the cargo area of most SUVs and has a built-in handle for carrying short distances.

These can vary, so you’ll need to check
If you’re taking a road trip with the Delta Pro, you can use the car charging cable to slowly recharge the battery while you’re driving. This way, you’ll arrive at your destination with more power than you had when you started your trip.
How can I tell when the EcoFlow Delta is done charging?
While your Delta Pro is charging, you can look at the LCD screen to see the battery percentage. This updates in real time. When the battery hits 100%, the input wattage reading on the screen will go down to zero or almost zero. The charging indicator lights will also show that the battery is fully charged. The Delta Pro doesn’t make a sound when it’s done charging, so you’ll have to check the screen if you’re close by.
Once you’ve paired the Delta Pro with the EcoFlow app, you’ll get a push notification on your phone once it’s fully charged. This is a lot easier than having to check the unit yourself. Plus, you can set up custom charge limit alerts. So, if you’d rather stop at 80% instead of 100%, the app will let you know when you’ve hit that mark.
