Strong Reliability
Power On, Hope On.
On a freezing Christmas Eve, our founder Leo was stranded on a deserted road: car battery dead, no signal, no help.
Hours in the dark, one idea struck—drivers need a tool that delivers hope instantly. That’s how Joltekon began.
With a team of engineers, Leo built a jump starter defined by performance, safety, and rugged design.
Today, it’s more than a jump starter—it’s an emergency solution for batteries, flat tires, drained phones, and roadside lighting.
Need help? Product not working or car won't jump-start?
We suggest checking the user manual first. If that doesn’t fix the issue, don’t hesitate to reach out—we’re happy to help!
Why can't I get this jump starter fully recharged? Only stuck at a certain battery percentage?
The battery self-discharges during storage, so the first charge may take longer (at least a few hours). Alternatively, drain the battery fully before charging.
Tips for using the air pump
6X faster pumping speed than other pumps, 5 inflation modes, 3 optional units, 5 nozzles for all your pumping needs! If you use inflator for a longer period of time, it is recommended to stop every 10 minutes to cool it.
