Can a regular outlet put those 32 electric miles back overnight? For most plug-in hybrids it’s close — it depends on your outlet and your parking.

Cost per mile: electric vs. gas mode
Plugging in vs. letting it run on gas
A plug-in hybrid gives you the choice every day. Here’s the same 40-mile day priced both ways — charged at home, or never plugged in. Drag the slider above to set your day.

EIA state-average gas price · EPA combined mpg with the battery depleted
Per mile, gas mode costs roughly 1.4× what electricity costs at home. Every mile inside the battery’s range is the cheap one — which is why a plug-in hybrid only pays off if you actually plug it in.
Level 1 vs. Level 2: can your outlet keep up?
The cost per kWh is the same either way. What changes is how much of the Mazda CX-70 PHEV’s 32-mile electric range comes back while it’s parked — and whether the rest of your day runs on gas.
Level 1 · standard outlet
~2 mi/hour
120V · no installation needed
Plugged in 6pm–6am: about 24 of 32 electric miles by morning (75%). Full electric range from empty: ~19 hours.
Level 2 · 240V circuit
~12 mi/hour
240V · typical 30A home circuit (7.2 kW)
Full 32-mile electric range in ~2.6 hours. Plugged in overnight, it’s full by morning every day.

If your daily driving stays under ~24 miles, a regular outlet refills the Mazda CX-70 PHEV every night. Drive more than that and the rest of the day runs on gas — not a problem, just a cost — unless you add Level 2 or a longer plug-in window.
Does a Level 2 install pay for itself?
A home Level 2 setup — 240V circuit plus charger — typically runs $800–$1,800 installed. For a plug-in hybrid the question is different: a regular outlet already puts back about 24 of the Mazda CX-70 PHEV’s 32 electric miles overnight (75%). Level 2 only earns its keep on the electric miles the outlet can’t cover — and the gas engine is the fallback, not a public fast charger.
Those 8 extra electric miles a night are worth about $0.29/day vs. running them on gas. At a mid-range install cost of $1,300, that’s a payback of roughly 12.4 years — and every night after that is pure savings.
Winter in Colorado
Colorado 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 Mazda CX-70 PHEV’s numbers at a 20% efficiency loss:
Cost per mile
~11.9¢vs. 9.5¢ in mild weather
Electric range
~26 mivs. ~32 mi
For a plug-in hybrid the range cut isn’t about getting stranded — the gas engine takes over. It’s about which miles you pay gas prices for: a day that fit inside the battery in summer (up to 32 miles) fits only ~26 in deep winter, and the rest runs on gas.
These prices assume you can charge at home. Can you?
Every number on this page depends on plugging in where you park. Most people underestimate what a regular outlet can handle — and some overestimate it. Answer 5 quick questions and get a clear answer for your home, your driving, and the Mazda CX-70 PHEV.

How much does it cost to charge a Mazda CX-70 PHEV at home in Colorado?
At EIA state residential average of $0.16 per kWh, a full charge of the Mazda CX-70 PHEV's 17.8 kWh battery costs about $2.88 — good for about 32 electric miles, or 9.5 cents per mile.
Is it cheaper to run a Mazda CX-70 PHEV on electricity or gas in Colorado?
Electricity. In Colorado, electric mode costs about 9.5 cents per mile versus about 13.1 cents per mile for its own hybrid (gas) mode (26 mpg) at $3.41/gal — roughly 1.4x cheaper. Every mile inside the battery's 32-mile range is the cheaper one, which is why a plug-in hybrid only pays off if you plug it in.
Can you charge a Mazda CX-70 PHEV on a regular outlet?
Yes — a plug-in hybrid is the best case for a standard 120V outlet. The Mazda CX-70 PHEV recovers about 2 miles of electric range per hour, so plugged in overnight (6pm–6am) it gets back about 24 of its 32 electric miles (75%). Restoring the full electric range from empty takes about 19 hours.
Do you need a Level 2 charger for a Mazda CX-70 PHEV?
Usually not. A regular outlet restores 75% of the electric range overnight; Level 2 fills it in about 2.6 hours. Level 2 adds about 8 electric miles a night, worth about $0.29 a day vs. gas — at a typical $1,300 install, that's a payback of roughly 12.4 years.

**Electricity rate is the EIA state residential average, Electric Power Monthly Table 5.6.A. Gas-mode cost uses the EIA state-average gas price ($3.41/gal) and EPA combined mpg with the battery depleted. Charging cost assumes home (Level 1 or Level 2) charging; efficiency and battery figures from the EV guide. Rates last reviewed AUG 2026.
