Ever wondered how those very small power banks are providing the electrical juice to our cellphones, well you have come to the right place to learn from the basics of what a gadget like a power bank is made up of.

Reminder, to  open only a power bank with the help of qualified technicians as they pack a small amount of power and could jolt you a bit especially those with higher mAmp settings.

I personally like the heavy duty chargers as they can be use several times to charge a phone so there is no need to constantly re charge your batteries.

Other materials you can find inside the charging battery includes the following items

  1. Lithium Ion battery
  • Charging control (integrated circuit)
  • Circuit board – this is the holder of the integrated circuit
  • USB ports- so we can plug our charger in our laptops or cellphones. So depending on the type of system your phone is using, special USB ports for Apple products or android phone is needed to match the charger and the phone
  • LED lights – sometimes the charger is design to contain indicators rather than displaying numbers for its charging status. Of course the fancy looking the charger is, the higher its price
  • Voltage regulators – this is already a part of the integrated circuit we mentioned

Normally it is divided in three categories, you should be able to select a power bank charger depending on your requirements.

7,500mAh range power of batteries are good for quick charing of small gadgets including phone of course but you can charge up to a maximum of three times only

7,500- 15,000mAh range power are called medium range battery power bank charges, these are a bit heavier than at  7,500mAh battery but it packs a stronger punch because you can charge your phone up to five times.

15,000mAh or more range can charge more than 5 times but are a little bit heavy to carry around so this is necessary only when you are going to long commuting or hiking activities that will have no immediate power source in outdoors.

Can Power banks damage your phone?

Make sure your power bank’s capacity is more than that of your device, first. For example, if your phone has a capacity of 2500 mAh, a power bank with a capacity of 2000 mAh won’t be able to fully charge it from 0% to 100%, however a power bank with a capacity of 10,000 mAh will be able to charge your phone from 0% to 100% multiple times.

Second, whenever purchasing or utilizing a power bank, keep in mind the voltage rating of your phone. Today’s cellphones typically operate at a 5V rate. Ensure that your power bank has a 5V output rating. The power bank will not charge your phone if the voltage is less than 4.2V. Instead, it will discharge the battery. If there are more, too
