Review: Excellent Customer Service - EDIT: Excellent Customer Service! The company reached out to me and issuued a replacement powerbank which was delivered very promptly free of charge. Fantastic service and great to see a company willing to go the extra mile to help their customers with any issues. Received the replacement powerbank today and it is brilliant! Thank you! Original review: Worked very well until the red USB port became detached from the board and ended up inside of the powerbank. Now it does not charge on any port and is slowly discharging itself, possibly due to the detached port causing a short inside the casing. Very good powerbank until this happened, but don't know if I was just unlucky.
Review: Great product, but not as fast charging and charging devices as I hoped for - Been very happy with this and the life it offers. Problem us fast charge in and fast charge out sits at about 11 watts and rarely goes above that using USB C to C. But as long as you don't mind it being a bit longer C to C than most chargers, it does the job

## 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.
