Introduction
I happened to be on the southern stretch of I-75 and decided to make a couple of stops for charging site reviews. Site visit was conducted on June 27, 2026.
Admiral
747 S Telegraph Rd, Monroe, MI 48161
Red E Charge
2 Stalls (1 CCS and 1 J3400; split 360kW site power)
$0.50 per kWh
The Admiral – Monroe station was the 2nd charging stop on this trip. I elected to stop and charge here instead of the nearby Tesla location because it should be faster and cheaper. This small gas station is soon to undergo major renovation with the EVSE potentially being moved and unavailable as part of the process. (Site opened in December 2025).
Accessibility
The Admiral site is an intersection corner location with the EVSE furthest from the major road. The site is 3.1 miles from I-75 at exit 13. West of the highway along slow speed city streets brings you to Telegraph Rd (M-24). South a bit at the intersection with 7th St. This single unit has one CCS and J3400/NACS that can be used at the same time. No dedicated accessible parking location. Pulling a trailer through this parking lot would be a challenge with no easy way to interact with the charger.
Amenities
Dining options include: Don Larson’s Bar
Shopping options include: Auto Value, Finishers Unlimited
Car-related services (windshield cleaning, air): Admiral gas station
Concentration
This is a single dispenser with one CCS port and one J3400/NACS port. Both can be used at the same time and the power will split. Angled parking would mean getting both vehicles positioned to connect easily would be challenging.
Location
This site supports I-75. Along this highway to the north are Detroit at 40 miles, and Flint at 100 miles. To the south are Toledo at 25 miles, and Dayton, OH at 180 miles.

150 Mile Range Estimate:
Speed
The Autel MaxiCharger DH480 unit used here can go up to 480kW. The power can be split and dispensed in 80kW increments. This unit was capped at 360kW total power. Cables are 400A nominal with a boost to 500A, enabling even 400V architecture vehicles to get their best speeds. At this site there is a 300kVA transformer, which means they are depending on the transformer to be able to oversupply to reach the peak power levels.
(150kW at 60% is average charging speed in the Ioniq 6)
Summary
This site is quite off the beaten path, and I would not recommend using it while on a road trip. This site is more of a local community support or opportunity charge location. In addition to the not great location, the amenities are not great either. Maybe with a gas station facility remodel this will become a more pleasant stop. The real highlight of this stop was the chance to use the ‘new to me’ Autel DH480. The implemented screens on this model are great and a step up from the already good MaxiCharger screens. They have now added the available current/power to show what the car is asking for, with the onscreen notes that power delivery is in this case limited by the car. The screen updated as the unit did the normal bring up the first 80kW unit and then bring more power as requested. During my session there remained 270kW available to the NACS connector.
What I paid for this stop:
Total Cost: $10.30 = $9.72+$0.58 tax
Total kWh: 21.61 kWh
Time: 10.2 minutes
Average Charge Speed: 127 kW
Cost per kWh: $0.45
Alternatives:
Burger King - 1975 Welcome Way, Monroe, MI 48162 - $0.57/kWh – 325kW x 12 (Tesla)
BP – 8733 Swan Creek Rd, Newport, MI 48166 - $0.45/kWh + $1 – 160kW x 4
