I bought this Circle CLI 10000 power bank and have been using it for a week, and it’s really an exceptional value for money product.
Pros: - The build quality of the product is very good and seems very durable - Fits into the purse very well, but it is little bulky and thick. - It has a torch LED light which comes handy in the dark. You press the button twice to turn it ON and also get to know the Power bank's charge. Press the button again to switch the light off. - Has charging indicator, the indicators go off but the charging of the mobile/table continues as long its plugged in. One thing which I loved about the product is it starts charging the device the moment you plug it in, no need to switch it ON. And turns off automatically after 10-15 secs of removing the USB wires. - Charging power
Input : 10.5W [5V / 1.5A] - Micro-USB
Output Power: USB Type A sockets power output below, Socket 1 - 5W [5V / 1A] - USB 2.0 Socket 2 - 10.5W [5V / 2.1A] - USB 2.0
To be honest, the charging power surely gonna drop if you charge 2 devices simultaneously, so to charge a device faster, try to charge a single device and use the 10.5W [5V / 2.1A] port.
- It can charge my S7 edge 2 times, when using the 5V 2.1A port with super fast speed.
Cons: - Charging the power bank to full charge takes a lot of time, I usually leave it for charging through the night. product.
Overall a very nice product by Circle, highly recommended for purchase as it comes with 1 year warranty.
