As someone with a Model 3 on order, I hate this decision to ditch the portable charger.
But as a Tesla investor. I'm loving it. Let's do some napkin math with round numbers and some guesswork for 2023:
Portable charger unit cost to Tesla: $100
2023 deliveries: 2 million
Shares outstanding: 1 billion
Tesla saves $200,000,000 ($0.20 per share)
But now assume 50% of customers buy the portable charger at checkout. That nets Tesla an extra $100 profit per car on 1 million cars (50% of 2 million).
So now we have $200,000,000 + $100,000,000 = $300,000,000 ($0.30 per share)
Now assume that with 100 million less portable chargers built, Tesla can use those precious chips to make 5% extra cars (100,000).
Average selling price: $60,000
Profit margin: 30%
Extra profit: 100,000 x 60,000 x 0.30 = $1,800,000,000
So now we have $1,800,000,000 + $200,000,000 + $100,00,00 = $2,100,000,000 ($2.10 per share)
Is my math right?
If so, based on my extra shareholder equity, I've made a lot more than I need to buy a charger for my Model 3.
