I dont see them mentioning about removing USB cable when not charging. I remove it from adapter anyway...so I dont think circuit completes anyway, so as good as removed.
And even after 5-6 full recharges.. its still giving max 7000 mAh
According to my observation, the led lights still flash when removed from the phone. Also, I have accquired a Sonypower bank where it is specifically mentioned in the manual to remove USB cable when not in charge.
Like any other product with a rechargeable battery, you should disconnect power supply after the batteries are fully charged. I am not sure what the confusion is?
actually after charging the phone through usb cable, people are leaving the usb cable connected to the power bank. so op wants to know whether battery will be used when usb cable is connected at one end to power bank and other end left free.
Yes, the LED keeps blinking sometimes even after disconnecting. Doesn't bother me much though. After all it's just a powerbank. I never really use the power button (or whatever that button is called).
