Baseus PrimeTrip VJ1 1200A Supercapacitor Jump Starter

The Baseus PrimeTrip VJ1 is a different kind of jump starter: instead of relying on a regular lithium battery, it uses supercapacitor technology. That means it does not need to sit fully charged in the trunk for months, and it is better suited for extreme temperatures than standard lithium-based jump starters. The idea is simple: even when the car battery is too weak to start the engine, it may still have enough residual energy to charge the supercapacitor. After a short charge, the VJ1 can deliver a strong starting current of up to 1200A. If the car battery is extremely low, the device can also be charged from another car battery, a phone charger, or a power bank. It is rated for petrol engines up to 4.0L and diesel engines up to 2.5L, with operation from -20°C to 70°C and multiple built-in safety protections.
