The Webasto Go Dual Voltage Portable EV Charger offers Level 1 and Level 2 charging (120V & 240V), ideal for home or on-the-go use. UL and IP67 rated for safety and durability, it delivers up to 7.7kW of power, charging up to 30 miles per hour. Compatible with all J1772-equipped EVs, including Tesla with an adapter.
The Webasto Go Dual Voltage EV Charger is a portable, dual-voltage EV charger with a strong reputation for quality and safety. Approved by top automakers like Ford, BMW, and Chevrolet, this charger meets rigorous automotive standards. It’s built to last, featuring advanced safety measures such as thermal detection, auto-restart, recovery, and ground fault detection, ensuring your peace of mind during use.
The Webasto Go is designed for simplicity, offering a plug-and-play experience. It supports both Level 1 (120V) and Level 2 (240V) charging, with adjustable current options from 12A to 32A. At maximum power, it delivers 7.7 kW, providing up to 30 miles of range per hour for most electric vehicles. The 20-foot cable length offers flexibility, and the included NEMA 5-15 and NEMA 14-50 adapters make it compatible with standard household and high-power outlets.
Installation is easy, with a wall-mounting option, but it lacks cable management. It also comes with a basic installation guide and no drywall anchors for mounting, which could be an inconvenience for some users. The unit’s price point is relatively high, and its two-year warranty may not be as long as some would prefer.
How the Webasto Go Dual-Voltage EV Charger Works
Architecture of a dual-voltage EV charger, illustrating the “logic hub” control system that enables safe operation across 120V and 240V power sources via intelligent adapter sensing and multi-threshold safety monitoring.
The Webasto Go Dual-Voltage EV Charger automatically switches between Level 1 (120V) and Level 2 (240V) charging using its Smart Plug adapter system. Each official adapter contains an embedded microchip that identifies the connected outlet, allowing the charger to automatically configure the correct voltage and maximum current without requiring manual settings or a mobile app.
When connected to a NEMA 5-15 household outlet, the charger delivers up to 12 amps (1.4 kW), adding approximately 2-5 miles of range per hour. Switching to the included NEMA 14-50 adapter enables 32 amps at 240V (7.7 kW), increasing charging speed to up to 30 miles of range per hour, making it well-suited for overnight home charging.
The Smart Plug system also includes built-in temperature monitoring at the wall plug. If the outlet begins to overheat, the charger automatically reduces power or stops charging to help protect the electrical circuit and improve safety.
Compared with the Lectron Level 1/Level 2 EV Charger, both products automatically switch between Level 1 and Level 2 charging, but they use different approaches. Webasto relies on microchip-equipped Smart Plug adapters to determine the available power, while Lectron chargers detect the incoming voltage internally through their control electronics. Another notable difference is charging capacity: the Webasto Go is limited to 32 amps (7.7 kW), whereas compatible Lectron dual-voltage chargers can deliver up to 40 amps (9.6 kW) on a 50-amp circuit, providing faster charging for EVs that support the higher power level.
Webasto Go Dual Voltage EV Charger Versus Other J1772 Chargers
The following chart compares key specifications (charging power, weight, operating temperature range, cable length, and warranty) of the Webasto Go Dual Voltage EV Charger with other EV chargers using the same J1772 connector type (direct competitors).
Webasto Go Dual Voltage EV Charger NEMA 14-50 Installation Guide
The diagram below shows the wiring configuration for installing a NEMA 14-50R outlet with the Webasto Go Dual Voltage EV Charger. It includes a 50-amp double-pole breaker, a main breaker, and neutral and ground bus bars in a 120V/240V panel. Components are labeled: L1 (Hot 1), L2 (Hot 2), Neutral, and Ground, using 6 AWG 90°C copper wire. Conduit sizing (¾”-1¼”) and grounding with a ground rod are also specified, ensuring compliance with US-NEC standards for a safe, reliable installation.

Webasto Go Dual Voltage Rebates & Tax Credits
The Webasto Go is a portable dual-voltage charger that qualifies for the 30% federal tax credit and handles both 120V and 240V outlets. Without connected smart software, it typically won’t qualify for utility ‘smart’ charging cash back, so your savings come from the credit and its low installation cost.
