Jonhon's reliable electric vehicle chargers are built for long-term performance. Constructed with die-cast aluminum enclosures and powder-coated finishes, they resist corrosion and impact. Internal components use industrial-grade parts (capacitors, relays) rated for 10+ years of operation. The chargers undergo 100% burn-in testing before shipment, and field data shows failure rates <0.5% over 5 years. With redundant power supplies and remote diagnostic capabilities, they minimize downtime for users.
