Its stated 26800mAh capacity, up to 85 jumps, 12-litre diesel capability, temperature range and 1000LM output are manufacturer claims, not independently verified.

Before relying on it for a particular vehicle, check the vehicle's requirements and the selected listing's exact configuration.

Customer feedback describes the unit as good quality and good value, but reports mixed experiences with battery power and functionality, including that it may not feel as powerful as advertised. That matters if dependable starting performance is the priority: the advertised 8000A peak and engine-size claims do not resolve the conflicting current figures or replace checking compatibility with a specific vehicle. Ratings are mostly five-star, but a notable one-star share points to a range of customer experiences rather than a guaranteed outcome.

Positive themes

Mixed feedback
