If floodwater reaches your EV charger, keep the power off, stay clear while water is present, and have it inspected before any reuse.
Yes – keep a smart charger’s firmware current for bug fixes, security patches and new vehicle and tariff support. Update on Wi-Fi, never mid-charge.
A home EV charger needs little maintenance: a monthly look-over, a seasonal cable and holster check, and a periodic test. Here is the routine.
Store a portable EV charger dry, loosely coiled and capped. How to coil the cable, where to keep the unit, and what to avoid in a trunk or garage.
A soft hum while charging is normal; loud buzzing, crackling, heat or a smell is not. How to tell charger sounds apart and which ones need an electrician.
Rain-only GFCI trips mean moisture is reaching a live part. Where water gets in, what you can check safely, and why the protection must never be bypassed.
An EV that stops charging before full is usually obeying a setting — a charge limit, a schedule, or a heat pause. How to read the pattern and fix it.
Repeated clicking with no charge starting means the charger and car keep failing their start-up handshake. The likely causes, safe checks, and when to call an electrician.
A granny charger has no surge protective device of its own. Real surge protection for a plug-in charger sits at the panel or consumer unit, not in the cable.
