1. In order to fully activate the battery, charge by an outlet or computer for 10 hours for at least the first 2-3 uses.
2. The energy transformation from solar to electricity is rather slow and the solar charging speed is subject to sunlight intensity and panel conversion rate. From day to day use, we highly recommend to charge charge your devices via wall outlet. Save the solar charger for those emergency uses.
3. Fully charging the solar unit by outlet takes approximately 10 hours. Do not over charge the unit by leaving it to charge all day or night.
4. For safety, DO NOT leave the power bank charging in a car in case of high temperatures and avoid crushing the unit.
5. Do not charge a device while the solar unit is charging itself.
