Things to Consider When Buying a Portable Charger

When choosing the best power bank, it’s important to check if the features of the models that you’re eyeing match your needs. Some of the factors that you need to take into consideration when buying a portable battery charger are its size and capacity, port types, and charging options.

Size and Capacity
One of the important things to consider is the size and capacity of the portable phone charger. These two features are usually interrelated since the higher the capacity, the bigger the size and the heavier the model. Portable chargers typically come in 5,000mAh, 10,000mAh, and 20,000mAh.

Chargers with a 5,000mAh capacity are usually small in size and can easily fit inside their handbag or pocket but they’re only good for a complete charge or two. Those with a 20,000mAh capacity can charge multiple devices numerous times but are usually bulkier and heavier.
Many people prefer to get something in between: a mid-sized portable charger that’s capable of a handful of charges. This type usually belongs in the 10,000mAh range and is good for general use.

Ports
Charging ports are another important feature to look out for when choosing a wireless portable charger. These determine how many and what kind of devices you can charge with your power bank, as well as determine the charging speed. Most chargers today have a USB-A port connected with a Type B connection for input and output.

With more and more devices utilizing USB-C, you may also find this port type in chargers available today. USB-C typically charges faster and combines the input and output functions. While some portable chargers may have USB-C input, not all of them have a USB-C output so check out the ports carefully.

Another port type is called Lightning and it’s used by Apple products. When looking for an iPhone portable charger, you need to make sure that it has the Lightning port. It used to be difficult to find chargers with Lightning but nowadays, many models offer it on top of the other port types.

Charging Options
Many power banks today are designed to give you the quick charge you need using various technologies, like fast charging. To be able to fully utilize fast charging, you need a battery, a cable, and a device with a charging circuit that meets the right standards.

Two of these standards are USB Power Delivery and Quick Charge. USB Power Delivery negotiates between the two devices to find the fastest charging option while the Qualcomm Quick Charge works by increasing voltage or the potential energy of the battery output. Quick Charge, as its name suggests, can power up supported devices up to 50% in just half an hour.

Another aspect of charging that you may want to consider is the power bank’s ability to charge devices while being powered up itself. This is called pass-through charging and can be very helpful when both your phone and charger are running low or when you simply want to keep your power bank at full capacity even when charging.

Wireless charging is another type of charging that’s been gaining popularity, with Qi as the most commonly used standard. With this, you don’t need to worry about which cables to use with which device. You simply have to place your device on top of the wireless portable charger and you’re ready to go.

Which power bank is better: 10,000mAh or 20,000mAh?
