6 Must-Know Technical Terms When Shopping for a Power Bank

Do you want to buy a power bank for your smartphone, tablet, and other mobile devices? If you do, there are certain terminologies that you will often encounter when you go shopping for this portable power source. Knowing what they mean can help you understand and determine the right power bank you should purchase for your devices. Let's take a look at some of them.

Technical Terms Related to Power Bank Use

1.mAh

mAh stands for "milli ampere hours." It is basically the unit for measuring the amount of stored energy in a battery. The mAh rating you'll see on power banks tells you how much energy they can transfer to the device that you want to recharge, like a mobile phone for instance. The higher the mAh rating of a power bank is, the longer or the more energy it can provide to the device to be recharged.

2. Volts and Amps

Volt is basically the electrical pressure or strength of an electrical current. Amp, on the other hand, is the amount of electrical volume that moves through an electronic device. When buying a portable powerbank, it is more important to consider its amp because it can affect how fast or slow the power bank can charge a device. The lower the number of outputted amps, the longer it will take it to recharge an electronic device.

3. Output and Input Current

Output current is expressed in amps (as explained above). It tells you how much the charger is capable of producing the power you need and how quickly. Input current is expressed in volts. It indicates the amount of power coming into the power bank.

4. Standby Time

Standby time tells how long a power bank can hold its change when it is not being used.

5. PCB

PCB stands for Printed Circuit Board. The PCB basically controls the flow of electricity inside the power bank. A PCB with excellent quality will enable the power bank to charge more electronic devices and help ensure its durability.

6. Li-ion and Li-poly

Li-ion and Li-poly refer to the components used in battery packs. Li-ion is usually much cheaper and it has a higher energy density as compared to Li-poly. Li-poly, on the other hand, is a newer innovation and is used in the batteries of many mobile electronic devices today. Li-poly is usually more expensive because it is safer to use.

When you go for shopping, be sure to look out for these terminologies so it will be much easier for you to find the externalbattery charger that you need.
