The compact power bank by Poweradd is suitable for emergency charging for a variety of mobile devices up to two times. This power bank has a cylindrical design; it is small 11 cm in length, and lightweight, 99 grams, being very easy to carry in pockets, handbags, backpacks, etc.
It can be used on the go for travelling and for any outdoor activities. The power bank has a 5000mAh Li-ion rechargeable battery and can charge fast one mobile device at a time.
At one end of the cylindrical shape of the power bank, there is a USB port (output 5V/2.4A) to charge mobile devices and a micro USB port (input 5V/2.0A) for charging the power bank using the micro USB cable provided.
A storage pouch included with the power bank is useful to protect the power bank from dust and scratches, making it also easy to carry it.
I tested this power bank with Android phones and tablets. My phone was charged fast twice and my tablet once.
The power bank is protected against short circuit and overloading while charging. I find this power bank very useful during the day keeping my phone charged while away from home, so I can use it as often as I like.
