Most quality portable EV chargers are weather-resistant rather than fully waterproof. A control box rated IP65 or IP66 is protected against dust and against water jets from any direction, so rain is not a problem. They are not designed to sit submerged in a puddle, and the grid plug and outlet are usually the weakest points, not the charger itself.
What IP Ratings Mean
| Rating | Dust | Water |
|---|---|---|
| IP54 | Dust protected | Splashing water |
| IP65 | Dust tight | Low-pressure water jets |
| IP66 | Dust tight | Powerful water jets |
| IP67 | Dust tight | Temporary immersion up to 1 m |

Where Water Causes Problems
- The wall outlet. An outdoor outlet needs an in-use (“bubble”) cover rated for weather while plugged in.
- The grid plug. Most household plugs are not sealed. Keep the plug-to-outlet joint off the ground and out of standing water.
- The vehicle connector when unplugged. Use the protective cap or holster so water and grit do not collect in the pins.
Safe Charging in Wet Weather
EV charging systems are designed for rain. The connector carries no power until it is fully seated and the car and charger have completed their safety handshake, and the charger’s ground fault protection cuts power if leakage is detected. See can you charge an electric car in the rain.
- Hang the control box or keep it off the ground.
- Inspect the cable and plug for cuts or cracks before use.
- Never use a damaged charger or an extension cord in wet conditions.
Weatherproof Portable Chargers
EVDANCE portable chargers such as the EVDANCE EV-ACS4005T 40A NACS portable charger, the EVDANCE EV-AC04001U 40A J1772 portable charger and the EVDANCE EV-ACS3210E 32A Type 2 portable charger use IP66-rated housings and operate from -30°C to +50°C.
