Power Without Compromise at the Finish Line
Road marathons present an unusual power challenge. Medical aid stations, timing equipment, communications infrastructure, and event lighting must all run reliably for the full duration of the race — often twelve hours or more — at fixed positions along a route that crosses streets, parks, and underpasses with no access to grid power. For a large-scale marathon event held in a major Japanese city, diesel generators had been the standard solution for years. But as the event grew in profile and urban noise restrictions tightened, race organizers began looking for an alternative that could deliver the same reliability without combustion engine noise, exhaust emissions, or the fuel logistics required to keep generators running across eight separate locations simultaneously. Conssin's KPS-0202 mobile power station was selected following a trial deployment at two aid stations during a smaller regional event the previous year, where it ran continuously for fourteen hours without incident.
Silent Operation Across Eight Aid Stations
Eight KPS-0202 units were deployed to medical aid stations spaced across the full 42km route, each powering a defibrillator, portable lighting array, communications radio charging station, and timing display board. Total load per station averaged 1.2kW — well within the KPS-0202's rated continuous output. Units were transported in event support vehicles and positioned by a two-person crew at each station in under ten minutes, requiring no tools and no fuel handling. Over the course of the event — from pre-race setup at 05:30 through the final runner's finish at 17:45 — all eight units operated without interruption. Battery state of charge at the end of the event averaged 34% remaining across the eight units, confirming the runtime margin was sufficient even if the event had run significantly longer than scheduled.

"We eliminated eight diesel generators from the route and didn't lose a single minute of power at any station. The race medical director said it was the cleanest setup we've ever had." — Event Operations Manager, Marathon Organising Committee, Japan
The event organiser has since standardised the KPS-0202 across all outdoor events in their annual calendar, replacing diesel backup at every site where grid access is unavailable. Total fuel and logistics costs for temporary power have been reduced to zero for these deployments, and the transition has been highlighted in the event's sustainability reporting for two consecutive years.
The Right Power for Time-Critical Events
Events where medical equipment must not fail — and where a generator starting up mid-race draws the wrong kind of attention — demand a different class of power solution. The KPS-0202 was designed for exactly this kind of deployment: rapid setup, silent continuous operation, and enough capacity to outlast any single-day event without mid-day intervention. It charges from a standard AC outlet overnight, arrives on-site fully charged, and handles the full load of a professional event station without fan noise, exhaust, or fuel management. For event organizers, sports federations, or emergency response teams who need reliable off-grid power that disappears into the background, the KPS-0202 is available with no minimum order quantity for trial deployment.
