## Description

Product Description 3 choices available for recharging There are 3 choices for recharging the battery pack phone charger, which is more adaptable and supports charging cables and adapters for most mobile phones on the market. Bi-directional charging/recharging via USB C The USB C port supports bi-directional input and output, meaning you can charge your battery or mobile phone via the USB C port. Power bank with LED display Precise percentage display of battery level for easy reminders to recharge on time. Streak pattern With a non-slip pattern, it prevents your hands from slipping and causing the usb c power bank to fall off. Multi-protection The power bank is equipped with overload protection. Package contents Power Bank 30000 mAh × 1 USB A to USB C cable × 1 Storage bag × 1 Manual × 1 About rated capacity Throughout the market, the total battery cell capacity of the power bank is generally described on the product page, and is usually measured in the lab at a nominal voltage (generally between 3-4V). When a power bank charges a device, it needs to be boosted and converted into energy according to the needs of the device and the charging protocols before charging the device, and at the same time, through the loss of charging cables and the impact of different temperatures, this conversion will lead to natural energy loss (Joule's law). Conversion efficiencies are generally in the range of 50-70%, and the higher the power output, the lower the conversion rate will become, which is a common feature of all batteries on the market. The actual capacity released after conversion is the rated capacity of the batteries.

Review: Great - Fantastic power bank. On the heavier side but worth it for the capacity.

## Questions & Answers

**Q: Would this one be ok to take on an Aircraft**
A: I think it would be ok to take on an aircraft but a little bit heavy

**Q: Has anyone actually measured how long it takes to charge the power bank from 0% to 100% ?**
A: Hello
The charging time of the power bank depends on the charger you are using, if your charger is compatible with the 9V-2A PD fast charging protocol, it will take about 9-10 hours to fully charge the battery; if you are using a 5V-3A charger, then it will take about 13-14 hours to fully charge the battery. If you use a lower power charger such as 5V-2A or 5V-1A, then the charging time will take longer. We therefore recommend that you use a charger that is compatible with the 9V-2A PD fast charging protocol, then it will greatly increase the charging speed of the portable charger.
