A supercapacitor jump starter stores energy electrostatically instead of through a chemical reaction. It needs no internal lithium battery, can be recharged in minutes, tolerates very high discharge current and is rated for a far longer cycle life, making it suitable for fleets, workshops and cold-climate markets where lithium packs degrade or self-discharge in storage.
Yes. Because supercapacitors do not rely on electrochemical reactions, they keep delivering burst current at sub-zero temperatures where lithium batteries lose output. Exact operating temperature ratings differ by model and are listed in each SPKSTAR datasheet in our product catalog.
The SPKSTAR 1000A supercapacitor jump starter fully recharges in about 3 minutes. Models such as the 12V 1500A unit support PD 140W fast charging, and supercapacitor units can also harvest residual energy from a weak vehicle battery to start the engine.
The 12/24V 3000A heavy-duty model is dual-voltage and designed for cars, pickups and commercial trucks with engines up to 13L displacement.
Yes. SPKSTAR provides turnkey OEM/ODM services including DFM review, mold development, logo and color customization, packaging, firmware and custom PCBA design for jump starters, inflators, battery management systems and other automotive electronics.
SPKSTAR products are tested to CE, FCC, UL, UKCA and RoHS requirements. Certificate coverage varies by model and target market, and test reports are available to verified buyers on request.
