Pros:
1.Charging time with 18W charger is 7 hours. With 10 watt charger it takes 10.5 hours to charge completely.
(If your charger is 15W , it will still take 10.5 hours to charge).
2. It doesn't have a power on/off button. There is a battery level indicater button on side. When you press it once, it will show the battery level remaining.
If you press it twice, it will go on low- current discharge mode when you can charge devices like Bluetooth headphones and smartbands.
When you connect...
