Specifications

Full specifications for Watti Pro Gen2 Slim, 80 A
Charging
Output power what this means: Output power The maximum power the charger delivers. Higher power means a faster charge. This figure is the unit's own amperage times its supply voltage, which is what power means on a single phase AC circuit, so it can read slightly below a maker's marketing figure: a 40 amp charger on 240 volts is 9.6 kW even where the box says 10.	19.2 kW
Max output current what this means: Max output current The maximum current the unit draws. It sets the circuit breaker and wire size the install needs.	80 A
Charger level what this means: Charger level The EVSE class. Level 2 runs on a 240 volt circuit; Level 1 uses a standard 120 volt outlet.	Level 2
Charging outputs what this means: Charging outputs How many vehicles the unit can connect to at once. Most home units have one.	1
Connectivity what this means: Connectivity How the charger connects for app control, scheduling, and firmware updates, or whether it runs offline only.	Wi-Fi or Gigabit Ethernet, Cellular
Extra features what this means: Extra features Additional hardware the model ships with, such as a display, an RFID reader, or a card reader.	High Resolution Display, Radio Frequency Identification (RFID)
Idle power draw what this means: Idle power draw Power the unit draws while plugged in but not charging. Lower means less standby waste.	10.3 W
Installation
Form factor what this means: Form factor Portable units are cord sets that plug into an outlet and can travel in the car. Wall-mounted units install in one place, hardwired or on a dedicated outlet.	Wall-mounted
Input voltage what this means: Input voltage The supply voltage the unit runs on. Level 2 home chargers use 240 volts.	240 V
Cable and connector
Cable length what this means: Cable length Length of the attached charging cable. A longer cable reaches across a driveway or to a second parking spot.	25 ft
Connector what this means: Connector The plug that connects to the vehicle. J1772 (also called Type 1) fits most non-Tesla EVs; NACS (the Tesla style plug, SAE J3400) is the emerging North American standard. Some models are sold in both, so you pick the version when you order. Verified from manufacturer specifications, and left blank where it is not yet confirmed.	J1772 or NACS
Cable gauge what this means: Cable gauge American Wire Gauge of the charging cable. A lower number is a thicker conductor.	6 AWG
Identity and provenance
Model number what this means: Model number The manufacturer model number, useful for cross checking listings and permits. In some model numbers, x and # stand for variant positions such as color or cable length options.	EAWPG2SL80-####****
Manufacturer what this means: Manufacturer The ENERGY STAR partner that makes or private labels this model, which can differ from the brand name.	Electric Avenue Manufacturing
Sold in what this means: Sold in Countries where the model is certified for sale.	United States, Canada
On the market since what this means: On the market since When the model became available for purchase.	January 2025
Warranty what this means: Warranty The manufacturer's stated warranty. Terms can differ by country. Some warranties require product registration or professional installation; the manufacturer's page has the conditions. Verified from manufacturer documentation.	3 years
Safety listing what this means: Safety listing Independent safety certification for the unit. UL Listed and ETL Listed entries are confirmed against the public UL and Intertek directories where possible, otherwise against the manufacturer's own documentation. A blank means we have not verified a listing, not that none exists.	CETLus Listed

Practical numbers

Minimum circuit breaker: 100 A; the electrical code sizes circuits at 125 percent of a continuous load like EV charging
Full charge, 75 kWh battery: 3.9 hours if the vehicle accepts 19.2 kW AC; many cap at 9.6 to 11.5 kW
Full charge, 60 kWh battery: 3.1 hours if the vehicle accepts 19.2 kW AC; many cap at 9.6 to 11.5 kW
Cost per full charge (same for any Level 2 unit): $15.49 at the national average residential rate (May 2026); your electricity rate decides this, not the charger
Standby electricity cost: About $16.64 a year at the national average rate, drawn while the unit sits plugged in and not charging

A charger is a continuous load, so code sizes its circuit at 125 percent of the charger's rating: that breaker figure is the minimum, not a suggestion. On an older panel the wire run and any service upgrade can cost more than the charger itself, so price the electrical work before settling on an amperage. How big a charger actually finishes the job.
