A commercial charger is a long-term asset. Weigh these seven factors before you buy.

1. Power and charging speed

Match power to your use case: 7–22 kW AC for workplaces and destinations; 20–60 kW DC for compact sites; 120–480 kW for fleets, highways and high-traffic hubs.

2. AC or DC

AC suits longer dwell times; DC suits fast turnover. Many sites benefit from a mix. (See our guide, AC vs. DC EV Chargers.)

3. Connector standards

Ensure the connectors match your market — Type 2, GB/T, CCS2 or CHAdeMO. Dual-gun units serve two vehicles at once.

4. Certification

Insist on the right approvals — CE, GB/T, J1772, TELEC/PSE/JATE — for your region.

5. Protection and durability

For outdoor sites, look for IP54–IP65, wide operating temperature and full electrical protection.

6. Connectivity and management

OCPP support, app control, RFID and remote diagnostics keep your network manageable and future-proof.

7. Manufacturer and support

Choose a real manufacturer with 10+ years' experience and dependable after-sales — like DHES.
