EcoFlow DELTA Pro*2 + Double Voltage Hub
EcoFlow DELTA Pro + Double Voltage Hub
Note: This Product comes with 2 EcoFlow DELTA Pro and 1 Double Voltage Hub.
Introducing the world's first portable home battery with an expandable ecosystem for home backup, smart energy management, lower energy bills, and more. It's the next leap in portable power technology.

Power for any situation: DELTA Pro delivers up to 10.8kWh of capacity. With that, you're covered for any situation. That's the industry gold standard.
All the AC output you’ll need: A single DELTA Pro unit packs a 3600W AC output, which can be expanded up to 4500W with X-Boost technology. Power 99.99% heavy-duty devices at home, outdoors, or at work.
The world’s fastest charging portable power station: To reach record-breaking charging speeds at 6500W, combine AC, solar and smart generator together for multiple charging.
Fully charge in 1.8 hours: The battery management system ensures safety and longevity, while you charge DELTA Pro from a standard AC wall outlet within 2.7 hrs, and from 240V outlet within 1.8 hrs*.
Charge up at thousands of EV stations worldwide: For the first time ever with a portable power station, you can charge up at thousands of EV stations worldwide. This unique charging method gives you up to 3400W fast charging on the go.
Go renewable with 1600W max solar charging: You can use solar energy to charge DELTA Pro in just 4-8 hours. DELTA Pro has a wide voltage range from 11-150V, which makes it compatible with 90% of third-party solar panels with MC4 connectors.
Emergency power with Smart Generator: The EcoFlow Smart Generator serves as an emergency option that integrates with your DELTA Pro ecosystem. It auto-starts when your DELTA Pro hits a low level of charge, re-charges your DELTA Pro, and stops the engine all by itself once your DELTA Pro hits a full charge
A battery that last for years on end: DELTA Pro sports a brand-new LFP battery with 6500 cycles, which means you can use DELTA Pro for years and years before your unit reaches 50% of the original capacity.
Multiple ways to control & monitor: The new EcoFlow app gives you full control over DELTA Pro. You can access your power settings, such as charging and discharging levels, AC charge speeds, and more.

The Double Voltage Hub is a great addition for DELTA Pro owners needing more power. Connecting two DELTA Pro units together, this accessory lets you use electronics that are up to 240V or 7200W off the grid.

Double your capacity: Plans for using tons of energy off-grid? Link two DELTA Pro units and their battery management systems will distribute capacity evenly to anything plugged into this hub.
Even more output: House battery backup never had this much output. Chain two units together and your DELTA Pro’s will output a whopping 7200W, enough for even the most heavy-duty of appliances.
Portable & lightweight: The double voltage hub is easy to carry, and pairs with your DELTA Pro to bring even more versatility to your portable battery set up. Charge up, link your power stations and you’re good to go.
Three more outlets: The hub has two NEMA 6-20 outlets that power regular electronics as well as 20-amp power tools. It also has a NEMA L14-30 outlet, making it that much easier to switch out your old gas generator.
