## Can be charged with a single 100V home outlet
Charging the LBIRD's battery is as simple as plugging it into a standard 100V home outlet. No dedicated charging stand or construction is required. It's designed to seamlessly integrate into your daily routine—just plug it in before bed, and it's fully charged by morning. Charging time is approximately 7-8 hours. A full charge allows for a maximum range of 50km.
## Estimated cost per charge
The LBIRD's battery capacity is 48V・13Ah (approximately 0.624kWh). Based on an average household electricity rate of about 27 yen per kWh, the electricity cost for one full charge is estimated to be around 17 yen (this is an estimate; actual costs may vary depending on electricity provider and plan).
## No need to charge almost every day for short-distance travel
Typical daily travel distances—such as shopping, hospital visits, or accompanying walks—are usually a few kilometers to just over ten kilometers per trip. A full charge of 50km can cover several days of such daily movements. There's no need for a full charge every day; connecting to an outlet a few times a week is sufficient for daily use.
## Economic rationality of electric mobility
Electric propulsion, which does not require gasoline, is unaffected by fluctuations in fuel prices. Our company designs products not based on 'low purchase price' but on 'overall value that allows for long-term, worry-free use after purchase.' The low charging cost is one aspect of this overall value.
