The EA chargers in Barstow (next to Walmart / Panda Express) worked great going and returning. Did not stop in Henderson, but the EA charger at the Las Vegas Outlets on the south side of the strip also worked flawlessly.
I drove from Camarillo to DTLA to Vegas with a GT (21”) and would have made it if I was daring. There is an EA station in Barstow next to a Panda Express, so food won out. Fully charged in 45 minutes.
