Just plug the USB cable to an available device and it will fully recharge the power bank. The portable power bank is build to power all kinds of devices that use Micro-USB ports. Its lightning Port Adapter is somewhat hidden inside the power bank. However, it is just to the left of the area where the Micro USB attaches. The portable power bank is fairly simple to operate and light will stop blinking once it is fully charged. Normally smartphones can be fully charged in no more than 30 minutes. The number of blinks indicates the charge level, from one slow blink to fully blue. When you need extra juice for your phone, just remove the cable and plug it again. The USB cable in the package is only about 1.5 inches long, but it is sufficient to work. I was able to get anywhere from 1.0A to 1.2A on my phone. The main body of the portable power bank did not get warm when it was fully charged.

Cons & Using reminders

Well this portable power bank is really good for smartphone charging. However, it seems that when charging tablets, such as iPad, the power bank did not operate as good as when the portable power bank was charging phones. You may feel a little warm or a few lags when using the portable power bank to charge tablets. Actually, it is not what it was designed for.
