On-Track Electrification: SparkCharge’s Mobile Battery Charging Trailer Powers Out of Spec's $5K EV Endurance Race
Revolutionizing EV Charging—One Race at a Time
What happens when three electric vehicles (EVs), a race track, and a cutting-edge mobile charger come together? You get an electrifying display of how SparkCharge’s Mobile Battery Charging Trailer is redefining fast charging—anywhere, anytime.
Recently, Out of Spec Reviews, a leading YouTube channel in the EV space, invited us to support their latest series: a $5,000 EV endurance challenge. The twist? Each vehicle was a low-cost budget buy with limited range and outdated charging capabilities. Our role? Ensure they could keep driving, all without missing a beat.
The Setup: Mobile Charging Delivered Trackside
For this unique project, we provided Out of Spec with a Mobile Battery Charging Trailer loaded with our self-contained, rechargeable battery-powered chargers. The trailer was towed throughout their journey by a Tesla Cybertruck, offering full mobility and independence from grid infrastructure.
This setup gave their team the flexibility to charge wherever and whenever needed. Highlights included:
- 125kW DC Fast Charging (DCFC) delivered directly to vehicles
- Self-service operations via an onboard interface that’s simple, safe, and ready to use
- Rechargeable battery packs that can be topped up at any public DC fast charger
Real-Time Energy, On Demand

In this video, the Out of Spec team pushes three budget EVs—each under $5,000—to their limits at the NCCAR circuit. Running continuously in high-heat conditions, all vehicles were nearly depleted by race end, with some showing range estimates in the single digits.
That’s where SparkCharge stepped in.
With our trailer already on-site, the Out of Spec team pulled up, plugged in, and recharged—no delays, no infrastructure hassles, no downtime. Our batteries, capable of delivering 125kW of DCFC, made it possible to recharge all vehicles simultaneously, getting them powered up for the next leg of their adventure.
This kind of deployment illustrates SparkCharge’s mission in action: bringing energy to the EV—not the other way around. Whether it’s a race track, fleet yard, or remote site, SparkCharge delivers fast, flexible charging exactly where it’s needed.

Before the racing began, the Out of Spec crew needed a dependable recharging solution for their lineup. Enter SparkCharge. We provided them with a Mobile Battery Charging Trailer, which they towed using a Tesla Cybertruck—giving them complete control and flexibility throughout their test.
The trailer is powered by our battery-based EV charging technology, with each port capable of delivering 125kW of DC fast charging. Once parked, setup was quick and seamless. There’s no complex infrastructure or external support required—just roll in, power on, and plug in.
