The compressor runs ≈ 15 min per hour and starts by itself, the saw ≈ 10 min per hour, the lamps all the time.
Light, compressed air and wood cuts in a workshop or garage with no mains power.
Estimated values for one full charge, depending on the equipment and the working conditions.
With smaller loads, one charge lasts several hours (estimated values).

For work with 230 V electric tools, nomadX replaces the engine-driven generator: no fuel, no fumes and no engine noise.
| Criterion | nomadX | Diesel generator |
|---|---|---|
| Fuel | None needed: charges from a 230 V socket in about 2.3 h | Diesel, bought, transported and stored |
| Emissions at the work site | Zero | Exhaust fumes |
| Noise in operation | Under 30 dB | Engine noise |
| Enclosed spaces and tunnels | Suitable: produces no exhaust fumes | Exhaust fumes must be vented |
| Maintenance | No engine and no fan: natural cooling | Oil, filters and engine servicing |
| Socket voltage | 230 V pure sine wave, 230 ± 5 V | Depends on the model |
| Monitoring | App via Bluetooth, alerts and history | Depends on the model |
The nomadX values are those of the official datasheet. The capacity is 2.3 kWh per charge. For continuous work at high power, rotate several units: one works while another charges.
The price is applied automatically in the cart, based on the number of units.

Connect your phone over Bluetooth and see everything happening inside the generator.
Quiet operation
Under 30 dB, with natural cooling and no fan.
Zero emissions, zero diesel
Charges from a 230 V socket, with no exhaust fumes.
Shock-resistant metal structure
IP54 enclosure, protected against dust and water splashes.
An alternative to the diesel generator
3600 W continuous and 20 kW peak for heavy-start tools.
Datasheet (PDF) Specifications may be changed without prior notice, as a result of continuous product improvement.
About 2.3 hours for a full charge, from an ordinary 230 V socket (176-264 V, 45-65 Hz). The maximum charging power is 1200 W, at a current of 6 A (maximum 8 A), so a household or site socket is enough. Charging takes place at temperatures between 5 and 40 °C.
It depends on the power of the devices switched on at the same time, which can be at most 3600 W. As a guide, on one full charge, 1800 W of devices run for about one hour, 300 W for about 5 and a half hours and 100 W for about 14 hours. Send us the list of your devices and we will tell you how long it runs.
Yes. The peak power is 20 kW, with a peak current of 140 A, and the inverter sustains 4000-5400 W for over 500 seconds, 5400-7200 W for over 50 seconds and 7200-9000 W for over 10 seconds. The datasheet shows, for example, a 3.2 kW core drill or a 3 kW welding machine powered directly. If you have a specific tool, send us the model and we will confirm.
The enclosure is protected against dust, which does not enter in a quantity that would affect operation, and against water splashes from any direction. nomadX can work outdoors, on a construction site; it must not be submerged or exposed to a powerful water jet.
nomadX has no engine and produces no exhaust fumes, which is why tunnels and mining are among the uses listed in the datasheet. Cooling is natural, with no fan, and noise stays under 30 dB.
It weighs 23.8 kg and measures 526 × 211 × 485 mm, so it fits in a car trunk or in the site van. The structure is metal and shock-resistant, and the battery holds UN38.3 certification, the safety tests required for shipping batteries safely.
Working with tools (discharging) is possible between -15 and 55 °C, and charging between 5 and 40 °C. In storage: between -20 and 60 °C for up to one month, between -20 and 45 °C for up to three months.
On the housing, the indicator shows the battery level in 10 steps. In the mobile app (Bluetooth) you also see the input and output power, the cell temperature, the history and the alerts.
Yes. The price per unit drops automatically in the cart from 5 units and again from 10 units; the exact prices are in the "Volume prices" table on this page. For larger quantities or delivery to several sites, please request a quote.
