Response time

We aim to reply within 2-3 business days. ChargeTimeCalculator is run by a small team, so please bear with us during busy periods.

Scope

We can help with: corrections to device data, methodology questions, API access and pricing, and general feedback. We can't provide device-specific technical support or warranty service — for that, please contact your device's manufacturer.
