EcoFlow|DELTA 2 Power Station + DELTA 2 Smart Extra Battery Bundle

EcoSystem

Portable power was once a choice between clunky DIY arrays or small capacity. EcoFlow developed an all-in-one battery with an intimidating capacity that you can wheel around and stow away. Let’s take a deep dive into DELTA Pro by going over both the features you can see and the ones you can’t – plus the ecosystem of add-ons that let you do more with DELTA Pro. If you’re not really sure what a portable power station is, check out this page first.

Delta Pro Power Station

Structure

If you’re somewhat familiar with portable power stations, the fact that it has wheels might come as a surprise, but a telescopic handle on the front gives it the maneuverability of a suitcase. The body is made from rigid ABS plastic that has been infused with metallic particles so it’s both lightweight and resistant to abrasion. Commonly used outlets like USB and wall outlets are on the front, technical ports are under the front corner panel, and input ports are on the back. Four powerful fans on the top keep the battery cool to maintain high cycle life and top performance. 

Battery

We picked the LiFePO4 battery chemistry because this industry favorite has a long cycle life, long shelf life, and high stability. Since DELTA Pros will be used around the world in every scenario imaginable, we paired it with an all-star battery management system to handle atypical temperatures, voltages, and currents, while simultaneously preserving the battery’s cycle life.

X-Stream
EcoFlow"s proprietary X-Stream technology delivers one of the fastest AC recharging rates on the market. Using a built-in smart inverter, DELTA Pro can recharge its full 3600 watt-hours in 2 hours and 40 minutes at 1800W.

X-Boost
When the combined wattage of everything drawing power from DELTA Pro exceeds 3600 watts, EcoFlow’s X-Boost technology lets the unit accommodate 4500 watts worth of devices. Some devices will run at a lower wattage during this period – toasters may take longer and power tools may be less powerful, and some devices may not work at all. X-Boost shouldn’t be seen as a way to get 4500W out of DELTA Pro, but rather as a safety net so that a temporary surge in usage doesn’t overload the inverter.

Near, Far, Wherever 

DELTA Pro has physical buttons and switches for when it’s accessible, but the EcoFlow app lets you adjust, control, and monitor more. Connect at close range with Wi-Fi-based pairing or Bluetooth, or connect it to a home network to manage it from anywhere around the world.

LCD Screen

The oversized numbers and auto-brightness are designed for maximum readability at a distance, and the generous size of the display fits in key information for energy management.

USB Ports

The USB ports on the front are for powering everyday devices in DC, which is more efficient than charging from the AC ports. The USB-C ports are at 100W and can charge newer laptops.

20A Outlet

Anything that plugs into your home’s wall outlet can be plugged into these four NEMA 5-20 outlets, even professional 20-amp devices. These outlets vary by region to match what is used in the home.

30A Outlet

Mid-sized RVs and trailers need a higher amperage than a regular wall outlet can provide, which means most all-in-one batteries can’t be used as a battery backup. With DELTA Pro, the cable on your RV that normally plugs into a campground’s shore power box plugs into its built-in NEMA TT-30 receptacle. (Not to be confused with the NEMA 10-30 receptacle used for dryers and welding machines)

Solar/Car Charging Input Port

Recharge DELTA Pro on a DC current through this XT60 cable. It supports 12V/24V charging from a car outlet for when you’re on the go and up to 1200W from solar input when you’re where you want to be. Charging from a car outlet for a few hours will provide a relatively small amount of power that is better suited to keeping your DELTA Pro topped off than for meeting your energy needs. Three 400W solar panels linked in a series can fill all of DELTA Pro’s 3600 watt-hour capacity in 4 to 8 hours with the right conditions. It might sound like a long time, but remember, 3600Wh is a whole lot of power.

X-Stream AC Charging Port

X-Stream is an EcoFlow technology capable of recharging 3600 watts hours of capacity in 2 hours and 42 minutes. That number can drop to below 2 hours when charging from solar and AC simultaneously.

AC Charge Speed Switch

The Speed Switch toggles between fast charging and the speed you set in the app (or 400W by default).

Overload Protection Switch

If you do manage to exceed the output DELTA can handle and “trip it’s breaker” so to speak, press this button before continuing.

Extra Battery Ports

These two ports connect with EcoFlow’s Extra Battery or Smart Generator. Read more about them in the EcoSystem section below.

Anderson Port

Like the 30A AC outlet, the Anderson output port is another way for RVs and trailers to get 30 amp service. Some swear by it for its versatility and efficiency, though it may require some know-how to set up if your outfit doesn’t have it integrated yet.

Car Outlet and DC 5521

Why is it that as the automotive industry is dropping 12V accessory outlets, portable power stations are picking them up? Car outlets are still a great way to get power from the battery without losing energy to DC to AC inversion – things with a car outlet are more efficient. The same goes for the two DC 5521 outlets for 5.5mm barrel plugs that appeal to a techier audience.

Remote Control Port

EcoFlow’s Remote Control shows DELTA Pro’s screen from a wired or wireless connection (see the Ecosystem section below for more info). Since the wired connection uses an Ethernet cable, it’s possible to run the cable for long distances and install Ethernet wall jack.

Standby Switch

DELTA Pro normally powers off after two hours of not being used, but when switched to standby mode, it can power on when something tries to draw power or remotely from the app or the Remote Control.

Infinity Port

We came up with this port because we needed something that was as smart as USB with the power of AC. Why? It lets DELTA Pro connect to another DELTA Pro or to the Smart Home Panel for home integration. It’s also how you can charge DELTA Pro from an EV charging station, just like you would an electric vehicle.

THE ECOSYSTEM

It’s hard to talk about DELTA Pro without looking at the ecosystem surrounding it. By ecosystem we mean all the add-ons that are compatible with a DELTA Pro so you can do more with it. Charge from an EV charging station, integrate DELTA Pro with your home circuitry, use a smart gas generator for worst-case scenarios, or connect a second DELTA Pro for the highest output available from a portable power station.

Smart Home Panel

Essentially a second breaker panel, the Smart Home Panel connects the battery capacity of one or two DELTA Pros to your home’s light fixtures and wall outlets. Decide which rooms get battery power either from the panel’s interface or from the EcoFlow app. The panel is how DELTA Pro can get used year-round both as an energy management solution.

Backup: Using the panel cuts out the need to bring your portable power station inside or run extension cords to different parts of the house. It also makes it possible to power things that don’t have plugs like lighting, alarm systems, well pumps, bathroom vent fans, and ceiling fans. 

Energy management: The Smart Home Panel’s second potential benefit is for capturing cheaper energy when electricity prices are lower, and running your home on stored power when rates are higher*. You can set all this up on the EcoFlow app so the switch to battery backup happens seamlessly and automatically.

Double voltage: With one DELTA Pro connected to the Smart Home Panel, any 120V wall outlet in your home becomes battery powered. With two DELTA Pro units, the Smart Home Panel combines their voltage to power both your 120V and 240V wall outlets for things like dryers, ovens, water heaters, and even HVAC systems.  

 *Savings are dependent on an electricity plan where prices vary throughout the day and are not at fixed rates.

Double Voltage Hub

For insanely high wattage devices when you’re not at home, the Double Voltage Hub – like the Smart Home Panel – connects two DELTA Pro units to output 7200 watts. You probably don’t own anything that would draw that much, but multiple things used at once could. The hub is suited for both mobile workstations using heavy-duty power tools and off-grid living spaces with all the amenities. Power 240V devices through the NEMA 6-20 outlets and NEMA L14-30 outlet, whose twist-lock design makes it ideal for any situation where there’s risk of pulling the cord loose.  

EV Station Charging Adapter

DELTA Pro is the first portable power station capable of recharging from an electric vehicle charging station. With an adapter in the Infinity port, DELTA Pro can recharge from 0–100% in less than 2 hours at any Level 2 EV charging station.

Remote Control

A screen that mirrors DELTA Pro’s at a bigger size makes it easier to manage energy usage when DELTA isn’t right in front of you. Connect by Bluetooth for convenience or Ethernet cable to cover longer distances and added certainty.

Extra Battery Unit

DELTA Pro’s Extra Battery has the same look and the same 3600Wh capacity, just without the ports. Two Extra Battery units can triple a DELTA Pro’s capacity, and this trio can connect to another DELTA Pro with two Extra Batteries using the Double Voltage Hub or the Smart Home Panel. That’s 21.6kWh of portable power!

Smart Generator

It may seem we’ve become the very thing we meant to destroy, but keep in mind that gas generators and portable power stations have their own strengths. The reality of portable power stations is that you can’t just pour in more capacity during emergencies, and some scenarios may exhaust your battery capacity faster than solar can recharge it. EcoFlow’s Smart Generator plugs into DELTA Pro’s extra battery port and automatically turns on when DELTA Pro’s battery drops below a certain level. The Smart Generator runs until DELTA Pro is charged up to a level you set in the app, and then powers off. That’s added confidence knowing DELTA Pro always has a fallback for the worst case scenario. If that day should ever come, the Smart Generator can charge DELTA Pro during the day, so you can sleep peacefully while DELTA Pro powers on through the night.
