# 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.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

## What's free
