Electric vehicle owners looking for a dual-voltage portable charger have many options today. However, in our opinion, not many good options, because many products are neither safety-certified nor well-made by an established company, and will likely fail well before you sell your EV or your lease is up, if you use it for daily charging.

The Webasto Go doesn't fall into that category because it is both safety-certified and well-made. It comes from a company that has sold more than 125,000 EVSE and is currently offered as the standard portable charging equipment for the Volkswagen ID.4, Vinfast, and both the Ford Mustang Mach-E and the Ford F-150 Lightning. So we ordered one, used it for a few weeks, and then put it through our rigorous EV charger tests.

The Webasto Go dual-voltage portable EVSE is the supplied charger for Ford and Volkswagen's electric vehicles.

The Go is a dual-voltage EV charger and that means it can plug into both 120-volt and 240-volt outlets. It comes standard with two adapters that enable dual-voltage charging, a NEMA 5-15 plug for 120-volt charging, and a NEMA 14-50 plug for 240-volt fast charging.

Charging from a 120-volt outlet, the Go will deliver up to 1.4 kW, and when plugged into a 240-volt outlet, the 32-amp charger will deliver up to 7.7 kW. In addition to the adapters, the Go comes with a wall-mounting cradle and a carrying case.

The unit passed our cable deep freeze test, the automatic restart test, and the connector and charger drop tests. It did, however, fail the submersion test. We only conduct the submersion test on units that are IP67 (NEMA 6) or higher rated. Those ratings mean the unit should be capable of being submerged in up to 3 feet of water for 30 minutes without any water intrusion.

Unfortunately, as soon as we lowered the Go into the bucket of water it immediately entered into a fault state and shut off. The good news is the Go wasn't permanently damaged and did work again once the adapter inlet was dry. That wasn't the case when we tested the Pergear P2 portable charger. In that test, water poured into the body of the unit and it suffered a catastrophic failure.

The Go faulted when submerged in a bucket of water, but worked fine once the adapter inlet dried out.

We gave the Go a final rating of 4.4 stars out of 5 and added it to our recommended charger list. If it didn't have the problem with faulting in the submersion test it would have probably finished with 4.6 stars. It's a very good overall charger, especially for those looking for a lightweight, portable solution.

The other two issues we have with the Go are the price ($549.00) and the fact that Webasto only offers a two-year warranty. Three years is the standard warranty length for quality charging equipment, and we're disappointed that Webasto doesn't support the product with a three-year term.

The cost is also a little higher than some competing portable chargers, but it is safety certified and very well built, so paying a little extra is sometimes the least expensive way to go over the long term.
