The problem: a battery that was fine yesterday clicks and dies on the first cold morning, and your only option is waiting for someone with cables.
The fix: a jump starter that fits in your glovebox, starts your car on its own, and fills a low tire while you're at it. No second car, no stranger, no waiting.
What it does
Starts your car by itself – 1500A peak, up to 15–20 starts per charge on gas engines up to 4.0L or diesel up to 2.0L.
Fills tires – built-in 400PSI pump with a digital pressure display. Works for car, bike and motorcycle tires and sports balls.
Charges your phone – 20,000mAh power bank with USB-C output. 3-in-1 cable included.
Lights the way – LED flashlight with steady white and two flashing red emergency modes.
Built-in protection – guards against reverse connection, short circuit, over-current, over-charge and over-voltage.
Will it start my vehicle?
It's rated for 12V gas engines up to 4.0L and diesel up to 2.0L – most cars, crossovers, small SUVs and many V6s. It is not rated for large V8 trucks or heavy-duty diesels. Not sure? Check your engine size in your owner's manual, or email us and we'll tell you.
Getting the most out of it
Charge it fully when it arrives (about 4 hours), then top it up every 2–3 months.
It works from -4°F to 140°F. On nights colder than that, keep it indoors and take it with you – a warm battery starts cars, a frozen one doesn't.
It gives a weak battery the boost it needs. A battery that's completely failed or damaged needs replacing.
Get the ColdStart 1500 jump starter, the ThawSeat cushion and the Pocket Ember hand warmer together for $139.99 (save $19.98). Add all three to your cart and the kit price applies automatically.
