A small 30 amp level 2 charger can put another 10 miles of range in a 450 Wh/mi car in 40 minutes.
A 15 amp level 1 charger can put another 10 miles of range in a 450 Wh/mi car in 2.5 hours on paper, but practically it takes longer, over 3 hours if it downrates itself to 12 amps, and almost 5 hours if it chickens out to 8 amps.
Another 4.5 kWh of battery gets another 10 miles of range without charging.
Having a level 2 charger at home means any time you go home for just about any reason you can always take just about any trip again right away, without an expensive vehicle with an oversized battery.
