Power that works where you do
TRUE PORTABILITY MEETS RUGGED UTILITY
Goes where you go—through dust, downpours, and everything in between. The hand-carry power unit that delivers portability without sacrificing rugged performance—built for demanding job sites. .
WHY VOLTFLEX 2.5
Built for the location. Primed for the job.
Operate where generators can't
No exhaust, no noise, and no permits required. One-person portability for confined spaces, enclosed structures, and noise-restricted sites where combustion isn't an option.
Keep working through harsh conditions
Built to withstand dust, driving rain, and tough job sites while meeting rigorous safety standards for construction, film production, utilities, and government projects.
Scale power as the job grows
Connect additional units in series to expand capacity without replacing hardware. Start with 2.5 kWh at the point of work and grow your power only when you need it.
APPLICATIONS
One unit for multiple use cases & environments
01 · Construction
Power exactly where the work is
Gets power to confined spaces, upper floors, and crane heads that cable runs can't reach. No exhaust means no permitting delays, no Fire Marshal sign-off, no shutdown risk on enclosed build-outs.
02 · Film & TV Production
Closer to the shot than any generator
No noise, no fumes, no cable back to base. Positions on camera carts, inside heritage buildings, on vehicle sets — anywhere a generator is physically disqualified from the take. UL 2743 certified for studio lots.
03 · Industrial & Field Service
Certified for the confined spaces that matter
OSHA prohibits combustion in confined-space entry. The VoltFlex 2.5 is UL 2743 certified, zero-emission, and hand-carriable — the only powered option that satisfies the requirement and fits the space. Keeps service trucks self-sufficient in the field.
04 · Live Events
Power at the position, not the perimeter
Distributed, silent power for venue-restricted positions where cable runs are impractical and generators are banned. One person repositions between setups without waiting for logistics support.
THE VOLTSTACK DIFFERENCE
Portable power without the workarounds
IP65 rated. Built for the realities of the job site.
Starts at 2.5 kWh and grows with the job
Take power where the job is
Power without the upkeep
HEAD TO HEAD VS. HONDA EU2200
When the go-to can’t get in
| Portable gas generator | VoltFlex 2.5 | |
|---|---|---|
| Weight | ~21 kg — fuel adds carry weight and a second trip | 25 kg, self-contained — carry in and go |
| Noise | Engine noise prohibits use near crews, cameras, or buildings | Silent — no noise restrictions, no exclusion zones |
| Compliance | Exhaust and fumes rule out indoor, enclosed, and noise-restricted sites | UL 2743 certified — approved for construction sites, confined spaces, and studio lots |
| Output | 1,800 W continuous / 2,200 W peak | 2,400 W continuous / 3,600 W peak |
| Fuel | Requires fuel cans, refuels mid-shift, spill risk on site | Recharges from any 120V outlet in less than 3 hours |
| Maintenance | Oil changes, spark plugs, carburetor servicing | No maintenance — battery-electric platform |
| Visibility | No data — someone has to physically check it | LTE via NeuronOS — state of charge and location from anywhere |
