YES — Fully Compatible
This power station can reliably run your appliance.
The EcoFlow DELTA 2 Max is fully compatible with a Rotary Hammer Drill. It delivers 2400W of continuous power, giving you a 1200W safety margin over the 1200W draw. Under typical conditions, expect around 1.5 hours of uninterrupted runtime, or approximately 9.7 hours with real-world duty cycle factored in.

⚡ Power Math & Safety Analysis
The EcoFlow DELTA 2 Max delivers 2400W of continuous power, which comfortably exceeds the Rotary Hammer Drill’s 1200W operating draw. This gives you a 1200W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 1741Wh. Dividing this by the appliance’s power draw yields approximately 1.5 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 15% duty cycle, expect 9.7 hours of elapsed time before depletion.
