What is the lifetime of a Power Bank?
Lithium-Ion batteries used in Power Banks and smartphones will eventually lose their capacity over time (around 500 – 1,000 cycles depending on the battery size). This means that the larger the capacity of the battery, the less amount of times you will need to charge it, therefore, helping it last longer.
Why do some Power Banks take longer to charge?
Many Power Banks are only chargeable through USB ports, and depending on the Power Banks capacity, the longer it can take to charge. The larger the capacity, the longer the Power bank will take to charge.
What is the best capacity for me?
This is always a tough question as it depends on the device that you would like to charge. You will always need a Power bank that has a higher battery capacity to the device that you are wanting to charge. For example, an iPhone 6 Plus has a capacity of 2915mAh (milliAmpere hour*), for this, we would recommend a Power Bank with a capacity of 3,600mAh.
Promotional Power Banks are currently the best selling gadget to help you rise above your competitors, and I think that it’s safe to say that they aren’t going anywhere anytime soon.
*It is a measure of a battery’s energy storage capacity. If you think of a battery as a small fuel storage tank, which in a sense it is, mAh a measure of how much “fuel” the battery holds.
