Will a car jump starter with supercapacitor really work in extreme cold like -45°C?
Cold weather significantly reduces lithium battery performance. However, the JS629 is engineered as a portable emergency supercapacitor jump starter capable of operating in temperatures as low as -45°C (-49°F). Because capacitors are not dependent on chemical reactions like lithium-ion batteries.
• No capacity loss in freezing temperatures
• No slow discharge issues
• No cold-related swelling risks
This makes it ideal for SUVs, and professional roadside assistance in harsh winter climates.
How long does it last, and how do I use it properly?
Unlike lithium jump starters that gradually lose capacity over time, this ultra-capacitor jump starter supports up to 500,000 charge/discharge cycles. So when your car won’t start on a freezing cold morning, you can rely on it immediately — even after long periods of non-use.
Simply follow these four steps to get back on the road:
Step 1: Attach the Clamps
Step 2: Power On & Self-Charge
Step 3: Start the Engine
Step 4: Detach & Drive Away
