Serious power, single-hand portability.
POWER WELDERS. START COMPRESSORS. CARRY IT TO THE WORK.
VoltFlex 3600 delivers 3,600 W continuous output and up to 20,000 W peak surge for welders, pumps, compressors and other demanding equipment — in a 24 kg package one person can carry. .
20,000 W
Peak surge power
Handles demanding startup loads from motors, compressors, welders and other high-inrush equipment.
2,354 Wh
Energy capacity
12% more energy than the leading hand-carry battery.
IP44
Rugged protection
Built to withstand dust and water spray on real jobsites.
Grid-level power without the generator.
Run demanding corded equipment without bringing a gas generator along. VoltFlex 3600 delivers the sustained power and startup surge needed for pumps, grinders, saws, compressors, welders and more.
A load curve built for real startup draw.
VoltFlex 3600 doesn't just advertise a big peak number. Its tiered surge capability delivers 9,000 W for 10 seconds, 7,200 W for 50 seconds and 5,400 W for 500 seconds — giving equipment the headroom it needs to start hard and settle into steady-state operation.
One person, no equipment.
No forklift. No cart. No second set of hands. VoltFlex 3600 goes where the work goes.
Silent, zero direct emissions.
Zero direct emissions and virtually silent operation make VoltFlex 3600 ideal for indoor work, confined spaces, occupied buildings and noise-sensitive environments.
Protected against dust and water spray.
The aluminum enclosure is protected against dust and water spray and designed to operate from –15°C to +55°C. This is portable power built to get used — not babied.
Recharges between jobs, not overnight.
With up to 1,200 W charging from a standard 120V outlet, VoltFlex 3600 can recharge between jobs instead of sitting overnight.
Cleared for professional use.
Cleared for professional use across North American jobsites, production environments and fleets.
Built for the jobs that can't wait for power.
Construction
Take power into upper floors, interior spaces, remote areas and noise-restricted sites. Run saws, drills, pumps and other corded tools without a gas generator or long extension-cord runs.
Welding & Fabrication
High surge capacity gives welders the startup headroom they need. Take welding power into fabrication areas, service bays and confined spaces where conventional generators aren't practical.
Industrial & Field Service
Bring serious power directly to the equipment. Ideal for maintenance, testing, commissioning and service work where grid power isn't available — or where running a generator isn't an option.
Film & Live Events
Quiet, clean power for lighting, monitors, production equipment and other sensitive applications. Put power where you need it without putting a generator in the shot.
Emergency & Backup
Keep critical equipment running when grid power isn't available. Load it into a vehicle, take it where it's needed and power up without fuel or complicated setup.
Portability without sacrificing performance.
VoltFlex 3600 goes head-to-head with portable battery alternatives — and brings more power and more energy in essentially the same hand-carry class.
