For fleet operators or long-haulers needing a compact safety net, this unit bridges the gap between convenience and capability.

In real-world testing, the YESPER consistently fired up 8L diesel pickups and 12L gasoline trucks from dead batteries, even after sitting idle for weeks. Its pre-heating technology proved a game-changer in sub-zero conditions, successfully starting engines at -40°F without hesitation—a rare feat for lithium units. Charging is equally impressive: the 145W AC adapter refills the 36400mAh battery in just 60 minutes, while a 5-minute top-up provides enough juice for an emergency start. However, it begins to show limits on larger Class 8 rigs with dual-battery 24V systems—where sustained cranking demands exceed its output. The 27.5-inch cables, though well-insulated, struggle to reach deeply recessed terminals on some heavy-duty chassis.

Compared to brute-force units like the ODUKAKO CAT797, the YESPER trades raw power for ultra-portability and rapid recharging, making it ideal for drivers of medium-duty trucks, RVs, or service vans who prioritize ease of storage and quick recovery. It’s not built for mining trucks or 50L diesel monsters, but for the vast majority of over-the-road and regional haulers, it offers unmatched versatility in a palm-sized package. While the ODUKAKO dominates in sheer output, the YESPER delivers smarter, faster, and lighter performance—perfect for those who value preparedness without bulk.

Don’t let its modest footprint fool you—the Gillaway V10-1 is a cold-weather champion with a 10,000A starting surge that punches well above its price tag, making it the smartest budget play for medium-duty truckers.
