Use-case guide · 2026
An EV doesn't need a block heater or jumper cables for the traction battery, but it has a small 12V battery that runs the computers and door locks — and when that dies, the car is a brick. Cold also cuts range by 20–40% and makes tire pressure drop like any car's. The winter kit for an EV is smaller, but it's not nothing: a compact jump starter, the visibility basics, and the warmth kit for a roadside wait that doesn't end with a tow truck bringing gas.

Compact, safe clamps, and more than enough to wake an EV's 12V system. Keep it in the frunk or glovebox and top it off a few times a year.

For an EV that sits for weeks (second car, winter storage), a maintainer on the 12V battery prevents the most common EV 'dead car' call.

You can jump the 12V system — which is usually all that's needed to wake the car and let the high-voltage battery take over. Use a compact jump starter or cables at the manufacturer's designated 12V jump points; never touch the high-voltage system. Check the manual first.
Typically 20–40% at freezing temperatures and below, more with cabin heat running. Preconditioning while plugged in, using seat and wheel heaters, and keeping tires inflated recover some of it.
