Introduction
In the past I have done dedicated trips to review individual networks in the area. For this trip I combined stops at many new or significantly upgraded sites. This stop is like a local review of the same provider at Hampton Inn. Site reviews from July 7, 2026
Napa Valley Beverage Co
35030 Mound Rd, Sterling Heights, MI 48310
EV Charging LLC (EVGateway)
4 Stalls (2 dispensers with 2 ports; each dispenser rated for 240kW)
$0.45 per kWh
This small store at the corner of a busy intersection is also trying to cram in EV charging. I stopped by to see if the hardware and site layout here was any different than my previous review of a EV Charging LLC site. (Site opened in March 2026).
Accessibility
The Napa Valley Beverage Co is at the intersection of Mound Rd and 15 Mile Rd. The site is on the eastern edge of the parking lot, most easily accessed from 15 Mile Rd. M-53 is one mile to the east and I-75 is 4.5 miles away. Not well placed for long distance travel support. Four ports, each dispenser having one CCS and one J3400/NACS cable. No signage for usage of these parking spots in any accessible way, with both credit card readers mounted above a standard accessible height. No stall designed for pull thru parking.
Amenities
Dining options include: Burger King, Johnny’s Coney Island
Shopping options include: None
Car-related services (windshield cleaning, air): BP across 15 Mile
Concentration
Four ports across two dispensers. Each dispenser seems to be able to output 240kW, however the right-side unit was not well marked. That 240kW of power does seem to be able to split, again no clear indication of exactly at what power level this splitting is supported.
Location
While this is a destination charge point designed to support those who live locally with no at home charging, it can be used for some travel. To the north Flint is 55 miles away, to the west Lansing is 100 miles, and to the south Toledo, OH is 80 miles.

Speed
Searching based on the name plate, this unit seems to be made by Chinese company Teison; their DC Pro series. From the name plate available this unit can output up to 350A per port. I am not sure if the right unit is paired or separate from the left unit, as it seems to be from a different manufacture. At this site there is a 300kVA transformer, hopefully these units have been configured to split the power and manage this input power limitation.
Both units use different cables and connectors. The left uses Sinbon and the right uses Amphenol. In all cases all the cables/connectors appear to be rated at 350A.
Summary
Seeing this site changes my feelings on the previous site of this type. Apparently, the cable management on these units doesn’t prevent the cables from laying on the ground, or the installers haven’t figured out how to enable this. To this end, they have opted to just place a mat for the cables to lay on and get dirty. I am sure that dirt will quickly get on anyone trying to maneuver thick and heavy air-cooled cables, not to mention snow and ice in the winter time. At least while I was there the parking lot was quite busy and not a lot of room to turn around for various charge port locations.
I did not charge at this location.
