PortaGrid vs a Leading Alternative: Which Portable Battery Power Unit Is Better?
Professional portable battery power is changing how contractors, maintenance teams, event organisers and film crews work without a mains connection.
The DyMac PortaGrid 3600 offers quiet 230V power without petrol, diesel or exhaust fumes at the point of use. But how does it compare with a leading alternative—and which features matter most for Irish customers?
Our comparison looks at battery capacity, continuous output, peak power, portability, expansion and after-sales support.
For buyers who prioritise stored energy, demanding equipment and accessible support in Ireland, PortaGrid presents a strong commercial proposition. The competing alternative offers a lower carrying weight and more extensive connected monitoring features.

Specifications, accessories and supported configurations should be confirmed when ordering.
Which Has the Larger Battery?
PortaGrid has a nominal battery capacity of 2,304Wh, compared with 2,074Wh for the competing alternative.
That is 230Wh more stored energy, or approximately 11% greater nominal capacity.
Additional battery capacity can be useful when powering site lighting, tool chargers, dust extraction, pumps, film equipment and other loads over an extended period.
Under equivalent operating conditions, a larger battery offers the potential for longer runtime. Actual working time depends on the connected equipment, system efficiency, temperature and operating cycle.
Estimated Battery Runtime
The following calculations illustrate runtime based on nominal battery capacity divided by a constant electrical load.
| Continuous load | PortaGrid: 2,304Wh | Competing alternative: 2,074Wh |
| 250W | 9.2 hours | 8.3 hours |
| 500W | 4.6 hours | 4.1 hours |
| 1,000W | 2.3 hours | 2.1 hours |
| 2,000W | 1.15 hours | 1.04 hours |
| 3,600W | 38 minutes | 35 minutes |
These are theoretical figures before conversion losses and other operating factors. They are not guaranteed runtimes.
Tools used intermittently may deliver considerably longer working sessions than these continuous-load examples suggest.
Continuous Power and Peak Power: What Is the Difference?
Both units provide 3,600W of continuous output.
PortaGrid has a stated peak output of 20,000W, compared with 18,000W for the competing alternative.
Peak power helps accommodate brief starting demands and temporary load surges. It can be relevant when assessing equipment with electric motors, such as pumps, compressors and dust extractors.
However, peak ratings must be considered alongside their permitted duration and the equipment’s starting characteristics. A higher headline peak figure alone does not guarantee compatibility with every machine.
PortaGrid’s 20,000W peak rating does not mean it can operate a 20,000W load continuously. Its continuous rating remains 3,600W.
Which Is Better for Professional Tools?
The best choice depends on the equipment being powered and how it will be used.
PortaGrid is particularly worth considering when you want:
- More nominal battery capacity.
- A higher stated peak output.
- Additional stored energy through a multi-unit system.
- A route to three-phase operation.
- Product advice and support through a Dublin supplier.
The competing alternative may appeal when you prioritise:
- A lower carrying weight.
- Connected location tracking.
- App-based monitoring.
- Digital oversight of equipment across multiple sites.
Before choosing a unit, check the combined running load, starting demand and expected operating time of your equipment.
Can PortaGrid Be Expanded?
PortaGrid can be used in an expandable system with the appropriate approved connection equipment.
The combined nominal battery capacities are:
- One unit: 2,304Wh.
- Two units: 4,608Wh.
- Three units: 6,912Wh.
This gives businesses a way to increase available stored energy as their requirements grow.
The connection arrangement determines the available output and operating mode. Additional units should not be assumed to increase power automatically in every configuration.
Can PortaGrid Supply Three-Phase Power?
Three PortaGrid units can be configured with the appropriate connection system to provide 400V three-phase power, approximately 11kVA combined output and 6,912Wh nominal battery capacity.
This expands the potential applications beyond standard single-phase equipment, including suitable construction, maintenance, workshop and event loads.
The competing alternative also supports three-phase operation through its own approved connection system. In the three-unit configurations compared here, PortaGrid provides 690Wh more nominal stored energy.
Suitability depends on the connected machine and the limits of the complete system.
Charging and Portability
PortaGrid has a stated maximum charging input of 1,200W, compared with 960W for the competing alternative.
Charging input is only one part of the comparison. Battery size, charging controls, temperature and the available supply also affect recharge time.
PortaGrid weighs approximately 24kg, while the competing alternative weighs approximately 20kg.
That 4kg difference may matter when carrying equipment upstairs, moving between work areas or accessing remote locations. Buyers should weigh this portability advantage against PortaGrid’s additional battery capacity and local support.
PortaGrid’s Irish Advantage: Local Product Support
For professional users, after-sales support deserves the same attention as power output and battery capacity.
PortaGrid is available through A-Z Hire in Walkinstown, Dublin 12, giving Irish customers a local contact for product advice, sales enquiries and support coordination.
DyMac Global also has an Irish base in Dublin 12.
When comparing suppliers, ask practical questions:
- Who handles technical enquiries?
- Where are inspections and warranty assessments carried out?
- Can the proposed configuration be demonstrated?
- What repair and replacement arrangements are available?
- Who can help match the unit to your equipment?
Local access to advice can help businesses make a better purchasing decision and manage problems when equipment is needed for a scheduled job.
Can PortaGrid Replace a Petrol or Diesel Generator?
For suitable loads and operating periods, PortaGrid can provide a practical alternative to a small combustion generator.
Battery power offers:
- No exhaust emissions at the point of use.
- No engine noise.
- No refuelling during operation.
- No engine oil changes or routine engine servicing.
- Portable power for locations without a convenient mains supply.
Potential applications include indoor maintenance, occupied buildings, urban construction, filming, events and work where engine noise or exhaust fumes would cause disruption.
Whether PortaGrid can replace a generator depends on the required output, runtime and access to recharging.
Our Verdict
PortaGrid offers greater nominal battery capacity, a higher stated peak output and more stored energy in a comparable three-unit configuration.
The competing alternative offers a lower carrying weight and more extensive connected monitoring.
For Irish customers who value battery capacity, expansion options and an accessible Dublin supplier, PortaGrid is a compelling choice.
The right purchase is the unit that meets your equipment’s demands and comes with the support your business needs.
