You are on I-5 with a dead battery. You open two apps on your phone. One is for a tow. The other is for mobile charging. Which do you tap? The answer depends on why the car stopped, how far you are from infrastructure, and what you actually need to happen next. Here is the honest framework for choosing, from a referral line that connects you with operators who do one of them and not the other.
We connect drivers with operators who run mobile charging. If your situation needs a tow, we will tell you on the phone. Here is the logic the operator uses to decide.
The first question: can the car drive once charged?
This is the only question that really matters. Everything else is secondary.
If yes, the car is mechanically fine, no collision, no warning lights, just empty, mobile charging almost always wins. Cheaper, faster, simpler.
If no, there is a fault that prevents driving even with a full charge, and a tow is the only real option.
Faults that require a tow:
- Collision damage (front end, suspension, airbags deployed)
- High-voltage warning triangle on the dash
- Smoke, burning smells, fluid leaks
- Dead 12V and dead main pack simultaneously with no response to jumps
- Flat tire with no spare (tow to a shop)
- Transmission or motor fault codes that block driving
Everything else is a candidate for mobile charging.
The freeway scenario
You ran the pack to zero on I-5, I-405, I-90, or SR-167. The car coasted to the shoulder. Hazards on. Nothing damaged, nothing leaking, no warning lights beyond charge immediately.
This is the classic mobile charging call. The variables:
| Option | Time | Cost | Result |
|---|---|---|---|
| Mobile charge (referral line) | 15 to 30 minutes charge once connected | Set by the operator | 15 to 20 miles added, drive to Supercharger |
| Tesla roadside tow | 45 to 120 minute arrival plus 20 to 40 minutes to load plus tow plus wait for charge | Free in warranty, billed out of warranty | 1 to 3 hours door to Supercharger |
| Paid tow | 45 to 90 minute arrival plus load plus tow | Set by the operator | Same as Tesla tow but on your dime |
For freeway strandings where the car will drive once charged, mobile charging is usually 30 to 90 minutes faster than any tow option. Our out-of-charge freeway guide walks through the same decision tree for the I-5 corridor specifically.
The dead in my garage scenario
You plug in at night. Something misfires. Morning comes and the car has no charge, the 12V is dead, and the screen will not wake. The car is safe, it is in your garage, there is no rush, but you need to get to work.
Mobile charging wins here for a different reason: it is cheaper than a tow to a Supercharger followed by an Uber home. An operator comes out, jumps the 12V, tops off the pack with 15 to 20 miles of range, diagnoses whether your home charger is the problem, and leaves. One call covers the jump and the charge. Much simpler than the tow pathway.
If you live in an apartment building without a charger, this is also where the referral line has a real answer. Operators carry the same gear they would use on a freeway shoulder, and the same 240V bed outlet can top up a pack in a parking garage. The operator confirms whether the parking garage allows the work, and the quote covers the trip plus the charge time.
The dead at a charger that broke scenario
You arrived at a fast charger with 4 percent left. The charger was broken, or your CCS connection handshake failed, or the next station was 50 miles away. You cannot leave, cannot charge, cannot cover the distance to the next station.
Mobile charging handles this cleanly. An operator comes out to the broken charger’s location, plugs into the car directly, bypassing the broken station, and adds enough range to reach a working station. One stop instead of three: no flatbed wait, no ride, no charging session at the other end.
A tow would haul you to the next working station. Longer, more expensive, and you have still lost the trip time.
The Snoqualmie Valley and east of North Bend scenario
This one is where the calculus changes. If you are out past North Bend, Snoqualmie, or on US 2 east of Monroe:
- Snoqualmie Valley and US 2 runs take longer, and the operator says so up front.
- The nearest tow might be further, rural flatbed coverage is thinner.
- Daylight and weather matter more.
For in-range Snoqualmie Valley calls (North Bend, Snoqualmie, Fall City), mobile charging still often wins. For truly remote scenarios (deep back roads past Gold Bar or up to Stevens Pass), a tow with winch capability may be the only practical answer. Call the referral line and we will be honest about whether an operator can reach you fast enough.
The I do not know what is wrong scenario
The car will not move. You do not know if it is the 12V, the pack, a firmware thing, or something mechanical. Warning lights may or may not be on.
Call the referral line first at (206) 202-7018 to reach a local operator. The operator does free phone triage. Tell them the symptoms and they will tell you whether mobile charging solves it or whether you need a tow.
If it turns out to be a mechanical fault that cannot be fixed on site, the operator does not charge you for the diagnostic call. They will say this needs a tow to service and give you a number.
Cost breakdown
Mobile charging is priced to be the cheap answer for the scenarios it fits:
- Priced by the operator. Includes the roll and the first 15 minutes of charge, about 10 miles added.
- Distance is the main cost driver. Most calls add 10 to 20 miles of range.
- Overnight calls usually cost more. The operator sets that, not us.
Compare to flatbed tow pricing in the Puget Sound:
- Flat rate: Set by the operator for a hook.
- Per-mile: Set by the operator after the included miles.
- Realistic out-of-warranty tow to a Supercharger or charger: depends on distance and operator.
For a typical empty pack, need 15 to 20 miles situation, mobile charging saves time and money versus any tow option.
Corridor patterns we see most
Working the referral line long enough shows patterns. The places we get the most calls:
- I-5 between Federal Way and Olympia. Long gap between fast chargers, climbing terrain south of Tumwater, range anxiety triggered.
- I-90 east of North Bend. Similar, the climb to Snoqualmie Pass eats more charge than drivers expect, and chain requirement events can sit traffic for hours.
- I-405 from Renton to Bellevue. High volume, dense stalls, but empty-pack arrivals happen when drivers leave home at 10 percent.
- US 2 east of Monroe. Rural, limited fast charging, Gold Bar corridor.
- Stevens Pass tourist runs on weekends. Drivers head up for skiing, realize the on-mountain charger is the only one for miles, and panic.
If you are planning a trip in any of these corridors, leave with more charge than feels necessary. 80 percent minimum for I-5 south past Tumwater, 70 percent for I-90 east past North Bend.
How to decide in the moment
Ask yourself three questions:
- Can the car drive if it had 20 miles of range? If yes, mobile charging. If no, tow.
- Is a fast charger within 20 miles? If yes, mobile charging adds just enough range to reach it. If no, mobile charging to home or a Level 2 charger, or a tow.
- Is there damage, smoke, or a warning triangle? If yes, tow. No exceptions.
Three questions. Ninety seconds. You will know which to call.
When to call the referral line
Call (206) 202-7018 to reach a local operator if:
- Your pack is empty and the car is otherwise fine.
- You need a 12V jump and the pack could use topping up too.
- You are stranded between chargers and need 20 miles to reach one.
- You are at a broken public charger and cannot complete a session.
