Estimate a charging stop's full cost

1. Check compatibility and usable access

Compare connector type, access hours, app or membership requirements and parking restrictions. A station's advertised power is a maximum capability, not the power your vehicle will sustain throughout a session. Check the operator's own instructions before relying on an unfamiliar location.

2. Separate energy and time charges

Write the unit next to every price: per kWh, per minute or per session. Add the car park's own charges and any idle rules separately. Do not compare a time-based tariff with a per-kWh price until you have stated an assumed charging rate and duration.

3. Keep a fallback stop

Availability is a current observation when supplied, not a reservation. A parking space being vacant does not establish that its charger is working. Save a compatible fallback and recheck the provider before travelling; keep promotional free-parking conditions separate from ordinary prices.

Work through a decision

Illustrative arithmetic, not a live tariff: 20 kWh at HK$3 costs HK$60 for energy. Two parking hours at HK$25 add HK$50, making HK$110 before any other fees. Replace every assumption with your operator's current terms.
