On the Big Island, it's nearly inexistent; there are Tesla destination chargers at the three main resorts, 5 level 3 chargers from the statewide electric power company, poorly maintained (rarely more than half working), and a couple of charging spots at the Costco, Target, Walmart, etc. Not an issue for me, as I charge at home only, using my PV array, and the range of 350mi of my LR RWD Model 3 will get me anywhere on the island and back, but a more serious problem for Leaf drivers and probably for owners of a base Model 3. Completely unsuitable for Cybertruck and I doubt it will get much better within the next 2 years. Better on Kauai (the one island not served by the statewide company, but by a coop). The only Tesla superchargers in the state are in Honolulu.
