How Long Does Mobile EV Charging Take?
Short answer: for most locations in our area, the quickest emergency option works out to under two hours from request to done, including the technician’s drive to you. That number comes from the same math that builds your quote, and you see your own exact estimate before you commit. A full charge from empty, done entirely on-site, takes longer, several hours once the technician is plugged in, because on-site charging runs at roughly the speed of a home Level 2 charger, not a public DC fast charger.
What determines the time
Two things, and they’re independent of each other. First, how far a technician has to drive to reach you, which depends on your location. Second, how much charge you choose to have delivered once they’re there, which depends entirely on which option you pick.
The four options, side by side
- Just enough. The fastest and cheapest: the minimum charge needed to safely reach a real fast charger.
- Recommended. The default. A bit more buffer, a bit more time on-site, for when you’d rather not cut it close.
- Full confidence. More buffer still, one step further than Recommended.
- Full charge on-site. Fills the battery the rest of the way. This is the longest option, since it’s compressing what would normally happen overnight into one visit.
Every option shows its own price and estimated time before you choose, right up until you pay. See How Our Pricing Works for the full breakdown of what’s in a quote.
How fast the charger really is
On-site charging is built around roughly 7.68 kW, in the same range as a typical home Level 2 charger. That’s an assumption we’ve since tested, not just quoted: a generator-powered session in August 2026 measured a steady 7.49 kW delivered into the vehicle, with voltage holding flat under load even with the car’s air conditioning running in 94-degree heat. The 7.68 kW figure we use to estimate on-site time turned out to be, if anything, slightly conservative next to what we actually measured.
That’s also why Just enough tends to be the fastest way back on the road after a mobile visit: a short top-up at Level 2 speed beats waiting through a full charge on-site, when the plan is to finish charging later at a public DC fast charger anyway.
Weather and timing
Cold weather affects EV batteries in general: range drops and charging can slow down in freezing temperatures, the same as it would at any charger, home or public. It doesn’t stop a technician from reaching you. If anything, cold snaps are exactly when a service like this matters most, because winter is when EV range runs out fastest.
Common questions
How long does mobile EV charging actually take?
For the quickest emergency option, it works out to under two hours total, including the time it takes a technician to reach you, using the same math that builds your quote. A full charge from empty, done entirely on-site, takes longer: on-site charging runs at roughly the speed of a home Level 2 charger, so filling a battery the rest of the way can take several hours once the technician is plugged in.
What determines how long a visit takes?
Two separate things: how far a technician has to drive to reach you, and how much charge you choose to have delivered once they're there. Drive time varies by location. On-site charging time depends entirely on which of the four options you pick, since each one delivers a different amount of energy.
What are the four charging options, and how do their times compare?
Just enough is the fastest and cheapest: the minimum charge needed to safely reach a real fast charger. Recommended, the default choice, adds a bit more buffer and takes a little longer on-site. Full confidence adds more buffer still. Full charge on-site fills the battery the rest of the way and takes the longest, since it's doing what would normally happen overnight at a full charging speed compressed into one visit. Every option shows its own price and estimated time before you choose.
How fast is the charger itself?
On-site charging is built around roughly 7.68 kW, in the range of a typical home Level 2 charger, not a public DC fast charger. We've measured this on our own equipment: a generator-powered session in August 2026 delivered a steady 7.49 kW into the vehicle, with voltage holding flat under load even with the car's air conditioning running in 94-degree heat. That's why the fastest way back on the road after a mobile charge is usually a short top-up (Just enough), not a full charge on-site.
Does weather affect how long charging takes?
Cold weather affects EV batteries in general: range drops and charging can slow down in freezing temperatures, the same as it would at any charger, home or public. It doesn't stop a technician from reaching you. If anything, cold snaps are exactly when a service like this matters most, because winter is when EV range runs out fastest.
Do I have to wait for a full charge?
No. Most people in an emergency pick Just enough or Recommended precisely because they don't want to wait for a full charge on-site, they want to get moving again and finish charging somewhere else, like a public fast charger. A full charge on-site is there for the times it's genuinely the better option, not the default expectation.
