I unpacked the part and wanted to charge it in the description. But lo and behold not go, only a charging plug for car power outlet is. Where should I stick it to when but the battery is empty? It would be better to have the charger packed for a 220 volt outlet. Not everyone has a home charger for mobile phone, pad or laptop. Is therefore only recommended for people with a fully charged car battery or someone who has a charger for electric appliances. From the description of Artickels is not apparent.
