Ottawa’s Cantec Systems offers a portable jump-start cart that’s powered by the company’s own Can-Crank capacitor. It can be fully recharged from its own internal battery, so it can be used in remote applications where there’s no readily available service vehicle or other power source. That full recharge takes less than a minute even from depleted on-board vehicle batteries.

The cart is said to have more power than four group 31 batteries, and can crank a dead vehicle’s engine repeatedly to higher rpm much quicker than batteries. Connection to the disabled vehicle is done by jaw clamps or a quick-disconnect plug.


The cart is available in 12- and 24-volt models, weighing 140 and 170 lb respectively. It’s 48 in. high, 20 wide and 26 deep. The capacitor is in an epoxy resin sealed case to protect from corrosion and it does not vent or leak because it’s without free liquid electrolyte, making it suitable in places with strict safety and environmental requirements. It’s also maintenance free, Cantec says, and its operating-temperature range is from  -45 to + 50 C.
