Two battery power supplies aimed at tool users are the Milwaukee ROLL-ON 3301R and the EGO POWER+ Nexus PST3042, and they target the same job as a small gas generator without exhaust. Milwaukee has not listed a price or Canadian availability for the ROLL-ON, while RONA lists the EGO Nexus at $1,599 CAD.

What does the Milwaukee ROLL-ON 3301R offer?

Milwaukee’s product page gives 7200W starting power and 3600W running power from a pure sine wave inverter. The 6.0kWh REDLITHIUM battery is built in and cannot be removed.

It has two 20A GFCI duplex outlets with circuit breakers, plus one USB-C and one USB-A port. Milwaukee says it charges to 100% in 8 hours and to 25% in under 100 minutes, and that pass-through power lets it charge and run loads at the same time.

Other listed details are an IP54 rating, 9.5” all-terrain wheels, a 3-year warranty, ONE-KEY integration and PACKOUT compatibility. The page shows no weight, no price and only a US country selector.

What does the EGO Nexus PST3042 offer?

RONA lists the EGO POWER+ Nexus PST3042 at $1,599 CAD, with two 56 V, 7.5 Ah batteries included. It delivers 2000 W continuous with 3000 W peak through three 120 V AC outlets and four USB ports.

It weighs 44.31 lb (20.1 kg), carries a 5-year limited warranty and a 3-year battery warranty, and accepts EGO 56 V batteries, up to four at a time. RONA gives no runtime figure, only an LED display for remaining time, and said stock must be ordered through a store.

How do they compare with a gas generator?

The main difference is exhaust. CBC quoted PEI Fire Marshal David Rossiter saying generator exhaust contains carbon monoxide, which you cannot smell or see. He advised pointing exhaust away from the house, never running a generator in an attached garage, and installing carbon monoxide detectors in every home.

Both products describe quiet, emissions-free operation. EGO says the Nexus is meant for indoor or outdoor use, though the weather-resistant build is what it highlights for outside. Neither maker’s page gives a total runtime, so match your loads to the stated watts and check the manual before you rely on either for an outage.

Who it suits

  • Tradespeople on the Milwaukee platform: the ROLL-ON is the larger of the two on paper, so check price, weight and Canadian availability before you plan around it.
  • Homeowners with an EGO 56 V kit: the Nexus reuses your existing batteries and comes with two, but 2000 W continuous will not run everything at once.
  • Crews that work indoors or in enclosed spaces: no exhaust is the clearest benefit, per both product pages.
  • Anyone on a tight budget: the stated Canadian price for the EGO is $1,599 CAD, and Milwaukee has not published one.

What to check next
