Huge battery to charge your tesla on the go?

The new mobile battery purports to act as a mobile Tesla charger. Thoughts?

With a 2 kWh capacity, virtually useless.

Yep... 2 kwh. Roughly the same as three car batteries, and enough to move a Tesla about 8 miles. I bet it costs a mile or more of range to move the ~300 miles it took to run down the HV battery to the point where you need to charge it.

LMAO, maybe 6-7 miles worth of range at best; don't forget 110V L1 charging inefficiencies and the fact that the damn thing needs its fans on during charging. So not even that ... You'll use more charge lugging the damn thing around in your trunk

A use case would be, if you plan going for hiking or trekking in the wilderness,
to be able to drive away from any public charging station located more than half the range of your EV.

I was considering doing some type of camping or boondocking in the National Glacier park,
but just crossing the park would be already a chalenge with any EV.
So getting some portable solar panels could be handy if you plan to drive off road.
