In brief: Smartphones like those from Samsung's Galaxy line have long shipped with a power-sharing feature that lets you share juice with other handsets, watches or earbuds in a pinch. Ford's new all-electric F-150 Lightning also affords similar functionality as one new owner recently learned.

While going through the vehicle's included accessories, the user stumbled upon a mobile power cord, a 14-30 to 14-50 adapter and a J1772 Tesla adapter. Other forum members had a field day with the prospect of coming to the rescue of stranded Teslas.

"We can help all those poor dead Teslas," the original poster said. "I'll add a bumper sticker "Tesla Rescue Squad"," another user quipped.

When pinged for comment, a Ford rep told The Verge that the F-150 Lightning can charge other EVs using its bi-directional charging capability. "We're shipping our first Lightnings with adapters so F-150 Lightning customers can lend a hand if needed," the spokesperson added .

Depending on the trim model , the F-150 Lightning can put out 2.4 kilowatts or 9.6 kilowatts from a variety of connectors in the cab, bed and front trunk.

Tesla sells a J1772 charging adapter on its website for $50. According to the listing, it is compatible with most Level 2 public charging stations and supports charging speeds up to 19.2kW. The adapter comes standard with the purchase of any Tesla, we're told.

As Electrek highlights , including the adapter with Lightning trucks is probably just a marketing ploy by Ford and a jab at rival Tesla. Still, it could come in handy in rare instances.
