Cost per mile by charging method
Yearly home-charging cost
Based on the Subaru Trailseeker’s efficiency (3.1 mi/kWh) at EIA state residential average. For comparison, a 30-mpg gas car at $3.50/gallon runs about 12¢/mile.
Home vs. public fast charging
Costs below are for a 10%–80% charge — the usable fast-charge window, about 52 kWh of the Subaru Trailseeker’s 74.7 kWh battery. That’s the range most owners actually use, since charging past 80% slows down sharply.

Typical public network pricing — varies by operator
Charging the Subaru Trailseeker on public DC fast chargers costs roughly 3.3× more than at home — about $18.30 extra per 10→80% charge. Most owners charge at home and only use fast charging on road trips, so your real average lands much closer to the home number.
Level 1 vs. Level 2: can your outlet keep up?
The cost per kWh is the same either way. What changes is how fast the Subaru Trailseeker recovers range while parked at home.
Level 1 · standard outlet
~3 mi/hour
120V · no installation needed
~13 hours to recover 40 miles of driving. Plugged in 6pm–6am, that’s about 36 miles overnight.
Level 2 · 240V circuit
~22 mi/hour
240V · typical 30A home circuit (7.2 kW)
~2 hours to recover 40 miles. Plugged in 6pm–6am, that’s up to 268 miles.
Most people assume they need a $2,000 Level 2 install. About 59% of people who take this check are already covered by a standard outlet.

If your daily driving stays under ~36 miles, a regular outlet may be all the Subaru Trailseeker needs. Drive more than that, and Level 2 — or a workplace charger — becomes the difference between an EV that fits your life and one that doesn’t.
Does a Level 2 install pay for itself?
A home Level 2 setup — 240V circuit plus charger — typically runs $800–$1,800 installed. If the alternative is relying on public fast chargers, home charging the Subaru Trailseeker in Washington saves about $112.90/month at 12,000 miles a year.
At a mid-range install cost of $1,300, that’s a payback of roughly 12 months — and every month after that is pure savings.
Winter in Washington
Washington averages about 3 months a year cold enough to cut EV efficiency — typically 15–25% in deep winter. Here’s what that does to the Subaru Trailseeker’s numbers at a 20% efficiency loss:
Cost per mile
~6.0¢vs. 4.8¢ in mild weather
Full-charge range
~225 mivs. ~281 mi
The cost bump is minor — a few dollars a month. The range cut matters more: if your daily driving is close to the Subaru Trailseeker’s limits, winter is when a marginal charging setup stops working.
