Battery Tender® eCharge 48 AMP, Level 2 Mountable Indoor Outdoor EV Charger

The fastest charger in the Battery Tender® eCharge lineup. The eCharge 48 Amp Level 2 delivers approximately 11.5 kW at 240V — adding roughly 30–36 miles of driving range per hour and fully charging most long-range EV batteries in 6–8 hours. For drivers of high-capacity EVs, households with multiple EVs sharing a single charger, or commercial and fleet charging applications where throughput matters, 48 Amps is the maximum output available in the eCharge line. Energy Star certified for maximum efficiency at full output.

Why 48 Amps

Vehicle onboard charger capacity varies significantly by make, model, and trim level. For vehicles that can accept high charge rates — many current long-range EVs accept 9.6 kW, 11 kW, or higher — 48 Amp Level 2 charging maximizes speed and minimizes the time the vehicle needs to be connected. For commercial applications and fleet operations where multiple drivers and vehicles share a single charging station, higher-output chargers reduce wait time and maximize utilization.

eCharge Level 2 Speed Comparison

• eCharge 32 Amp Level 2: ~7.7 kW · ~20–25 miles of range per hour
• eCharge 40 Amp Level 2: ~9.6 kW · ~25–30 miles of range per hour
• eCharge 48 Amp Level 2: ~11.5 kW · ~30–36 miles of range per hour

Actual range added per hour varies by vehicle onboard charger capacity and battery efficiency. Vehicle onboard charger capacity is always the limiting factor — a vehicle with a 7.2 kW onboard charger will charge at a maximum of 7.2 kW regardless of the station's output rating. The eCharge 48 Amp unit will deliver at the vehicle's accepted rate without issue.

J1772 Standard Connector

Compatible with all J1772 non-Tesla electric vehicles and plug-in hybrids sold in North America. The J1772 standard covers all major domestic and international EV and PHEV manufacturers.

RFID Access Control

Built-in RFID card reader enables access control and usage tracking for residential, commercial, or fleet charging applications. Restrict charging access to authorized users, track individual charging sessions, and manage utilization across multiple vehicles sharing a single station.

Energy Star Certified

The eCharge 48 Amp Level 2 is Energy Star certified — meeting EPA energy efficiency guidelines for EV charging equipment at full 48 Amp output. Energy Star certification ensures minimized standby power draw and optimized charging efficiency throughout every session, reducing the total cost of operation over the unit's service life.
