“We could cut roof tiles and run our lift—with no limitations and no time lost.”




Find PowerRock 4000 solutions for different contractor workflows.
Power jackhammers, concrete saws or submersible pumps with stable 4 kW output. IP65 protection keeps power moving through dusty, wet work zones—without bulky generators or long cable runs.


Power jackhammers, concrete saws, and submersible pumps with stable output.

Bring power directly to each work point, reducing generator moves and cable rerouting.

Protection against dust, rain, and water spray keeps you working.
*For optimal performance and operational stability, it is recommended to connect no more than three PowerRock 4000 units for chained charging or discharging.

Top up from AC during loading, with the EcoFlow Alternator Charger on the road, or from a generator during breaks.

Portable design helps crews move power between work areas with less setup time.

IK10 All-metal construction helps withstand accidental drops and daily transport across demanding jobsites.*

Monitor battery status, shut down remotely, and schedule AC charging around your workday.
See how PowerRock helps crews work beyond the limits of traditional jobsite power.
Beyond the Jobsite
Save more over time compared with a 6 kW diesel generator.

PowerRock operating costs remain nearly flat while generator expenses compound over time
≈ €4,000 saved after 1 year
4.3 L/day × €2.37/L + (6 h × €0.24/h) maintenance
≈ €11.63/day
Daily electricity cost
≈ €0.77/day
(€11.63 − €0.77) × operating days
= €10.86/day saved over time
*Estimated savings for illustrative purposes only. 6 h/day generator use · under equivalent load conditions · Diesel €2.37/L (CBS, Aug 2026) · Off-peak electricity €0.21/kWh · Generator maintenance €0.24/h. Actual costs may vary.

1. On this website, "EcoFlow" and EcoFlow's product and product-series names, such as "RIVER", "OCEAN" and "GLACIER" (collectively, the "Names"), are used solely as trade marks, brand names or other commercial identifiers. The Names, in and of themselves, are not used to make any environmental claim regarding EcoFlow or any of its products or services. In particular the Names alone do not indicate that EcoFlow or its products or services have a positive or zero impact on the environment, are less harmful to the environment than other products, product categories, brands or traders, or have improved their environmental impact over time. 2. "Grid-level power" refers to the high-capacity, stable AC output capable of powering demanding commercial and jobsite tools. "Work anywhere" is subject to the product's operating specifications, recommended operating temperature ranges, and safe operating guidelines in the user manual. 3. 7.2 kW peak power output is based on lab testing under optimal temperature and battery charge conditions; actual peak duration and output may vary based on remaining battery capacity and operating temperatures. 4. Compatibility with specific tools depends on the individual tool's actual rated and starting surge wattage. Please check your equipment specifications before use. 5. IP65 rating is tested under controlled laboratory conditions. Water and dust resistance is not permanent and may decrease with normal wear. All port covers must be securely closed to maintain resistance. 6. 1 m Drop Resistance based on lab testing under controlled conditions. Actual impact resistance may vary depending on drop angles, surface types, and environmental factors. 7. "Move power anywhere" refers to off-grid portability across typical jobsite work areas. Actual placement and operation are subject to the product's operating temperature range, environmental specifications, and IP65 conditions. Do not use or store the device in hazardous, potentially explosive, corrosive, or submerged environments. Always adhere to local safety regulations and guidelines in the user manual. 8. 1-hour fast charging requires maximum AC input under optimal ambient temperatures. Actual recharge time may vary depending on input voltage, grid capacity, and ambient temperature. 9. RCD stands for Residual Current Device. 10. Tool performance figures are based on EcoFlow lab testing under controlled conditions. Actual results may vary by tool, material, usage, and operating conditions. 11. The 200× faster heat dissipation and 250× longer overload duration claims are based on EcoFlow lab testing against an EcoFlow portable power station under controlled conditions. Actual performance may vary. 12. Estimated savings are for illustrative purposes only and are based on 6 h/day generator use under equivalent load conditions, diesel at €2.37/L (CBS, Aug 2026), off-peak electricity at €0.21/kWh, and generator maintenance at €0.24/h. Actual costs and savings may vary. 13. The metal housing is rated IK10, while the front panel is rated IK08. Based on data from EcoFlow’s internal laboratory testing.
