Power Bank Buying Guide

Battery packs are all the rage now. They come in numerous sizes and shapes, and there is a wide range in price.

It can be tricky to pick the best portable charger for your needs. It’s not always clear how the various standards translate to actual performance in your unique use case.

There is a wide range of power banks available, each with its own unique combination of form factor, capacity, and battery technology. Given these considerations, it’s important to shop carefully for the best portable charger to meet your needs.

How to Choose the Most Effective Portable Charger

Parity the voltage levels:

When shopping for or deciding on a portable charger, one of the most crucial factors to think about is the capacity needed. Consider what needs charging, as different devices have different charging requirements. Moreover, there are cellphones that require more juice than others. Just check your phone’s specs to see for sure. If you look under the battery section, you’ll see the battery’s capacity listed.

The amount of power is expressed in milliampere hours (mAh). This is expressed in mA h. So, a 1000 mAh battery can deliver 1 A for an hour at a current of 1000 mA. In contrast to today’s smartphones, which can have a 3000 mAh battery, older models likely had a capacity of under 1000 mAh. The iPhone X’s battery, for instance, has a capacity of 2716 mAh.

Power bank charge current output:

Consider the charging speed of a power bank’s output before making a purchase. The charging time is affected by this.

The included power adapters should give you a good sense of what’s required. In general, 0.5 A is sufficient to charge most USB devices, 1 A is typical for charging a smartphone, and 2.5 A is the maximum charge current for most tablets.

More power, up to 3 amps, will be needed to rapidly charge an item. As more and more gadgets get this capability, it becomes increasingly important to take note.

Count of available ports:

As more and more people began using power banks and saw the convenience of being able to charge numerous devices at once, manufacturers began including extra output ports on larger power banks. See if the available current output from each port is sufficient. Be aware that the power bank’s maximum current output may be shared across the outputs if numerous devices are charged at once, resulting in slower charging for all of the devices.

Mass and dimensions:

It’s crucial to think about portability while shopping for a power bank. The bigger and heavier the power bank, the more juice it can store.

Connectors for recharging:

It’s important to note that while the output connector of power banks is nearly always a USB Type A (the huge USB connector used to communicate with USB chargers, flash memory drives, etc.), the connector used to charge the power bank is different.
