Some features to consider when choosing a power bank

Size and capacity

Generally speaking, the larger the power bank, the larger the capacity and the more ports it has. Pocket-sized power banks can usually be used to fully charge your phone once or twice, while power banks designed to last a full day of use are usually larger.

Pocket-sized power banks typically have smaller batteries, with a capacity of 3,500mAh or less. Once the battery gets above 3,500mAh, the battery size increases and will no longer fit in your pants pocket, but will still fit in your jacket pocket. There are even power banks that can charge a tablet and still have enough power to charge your phone 10 times. Of course, these are usually the biggest and heaviest, and you'll definitely need a bag to carry them around.

Input and output ports

The second thing you need to look at is the power bank's charging port to see if it's compatible with the device you want to charge. At a minimum, most power banks have a standard micro USB port for input and a USB-A port for output.

USB-C generally allows for faster charging, combines input/output in one port, and many new phones have it. Be aware that some power banks have a USB-C input but no USB-C output.

Lightning is a proprietary Apple technology, so companies need to pay Apple when they use it, which makes it less popular.

Fast charging

Another factor to consider is the charging speed of a power bank. Power bank capacity is measured in voltage and amperage. Amperage is the amount of electricity flowing from the battery to the connected device, while voltage is the amount of potential energy. Multiply voltage by amperage and you get the power. To make a device charge faster, most manufacturers change the voltage or increase the amperage to increase the overall capacity.

Basically, when you want to buy a backup charger with fast charging capability, you need to see if the charger uses any fast charging standard and the battery and cable must support that same charging.

The two most popular fast charging standards in use today are Samsung's Adaptive Fast Charging and Qualcomm's Quick Charge. Both work in a similar way, increasing voltage rather than current. Samsung's Fast Charging only works with certain Samsung devices, while Qualcomm Quick Charge requires your device to have a compatible Snapdragon chipset. These standards allow you to charge a supported phone up to 50% in 30 minutes.

Power Delivery is a newer protocol where two compatible devices "negotiate" for the fastest charging option available, up to 20V/5A (with EMCA cables) if possible.

Pass-through charging and wireless charging

There is another thing to consider when choosing a power bank. Pass-through charging allows you to charge a device connected to the battery while the battery itself is being charged. This feature is useful if both your phone and the power bank are dead at the same time.

Wireless charging is also popular because it allows you to charge compatible devices without a cable by simply placing it on top of the power bank. Qi is the dominant standard on Apple and Samsung phones.

Should you buy a charging phone case?

If you tend to forget to bring a spare charger when you need it, you might consider using a charging phone case. It combines portability and protection with a built-in power supply so your phone can charge at any time. However, the downside is that it has a lower charging capacity than a dedicated battery and you can't charge anything other than your phone.
