Price What Charging a Mobility Device Costs — Free, From Your Own Tariff
Charger watts, hours on charge and your rate become a daily and annual figure, with a replacement battery or charger priced against the same usage. The free tier is the whole tool: every field, every state, the state link and one complete un-watermarked run. The one-time layer adds the printable copy and the local history shelf; it never removes or degrades the free result.

GratisAI priced charging my power chair from my own overnight tariff — about 46 a year, with the replacement charger never paying back.
Boundary: This estimates a running cost from figures you enter; it is not an energy audit, a benefits assessment or a maintenance check on the device. Battery condition, charger safety and any equipment that connects to the mains are matters for the device's supplier or a competent person — never modify a charger or a battery yourself.
