I wonder if a hack would be - just like a USB power bank to power your phone away from an outlet - to have a portable lithium ion battery (something like Jackery, the only name I know since I watched an LTT video about it[1]) to charge your car. You fill up the Jackery at home, and you drag it to your car when it's time to charge. Optimally you could leave it in inside your car while charging (otherwise it'd be stolen), and route the cable in a weatherproof way to the charger port. Alternatively, cars should start having a charging port inside the car. [1] https://www.youtube.com/watch?v=W1hZ9zJAd2s https://www.youtube.com/watch?v=W1hZ9zJAd2s

There's no way this can work when you consider that the battery packs in cars are massive. Wikipedia says that the long range version of the tesla model 3 weighs 1060 pounds. Assuming that energy density of your "portable lithium ion battery" is similar, you'd need to lug around a 200 lb battery pack just to charge your car 20%.

  Hmm, true. Plan 2: like a tanker truck (well maybe the dimensions of an F-150 truck or a U-Haul) but it's batteries . Your car park has no charging infrastructure? We place the truck there and electric cars can park around it and be charged. Just don't read the fine print about how explosive it'd be if the battery catches fire.
