Some features to keep in mind when choosing backup charger

Size and capacity

In general, the larger the backup charge, the larger the capacity and the larger the number of ports. Medium-sized standby chargers can often be used to fully charge the phone once or twice while backup chargers are designed to be able to use the device all day more often.

Pocket portable chargers usually have smaller batteries with a capacity of 3,500mAh or less. When the battery is over 3500mAh, the battery size increases and no longer fits your pocket, but it still fits into the jacket pocket. There are even backup chargers that you can charge your tablet and have enough power to supply your phone 10 times more. Of course, these types are usually the largest and heaviest and you definitely need a bag to carry it with.

Input and output ports

The second thing you need to consider is the redundant charging port to see if it is compatible with the device you want to charge. At a minimum, most backup chargers have standard micro USB ports for inputs and USB-A ports for output.

USB-C usually allows you to charge faster, merge input / output in one port and many new phones have this port. Note that some backup chargers have USB-C inputs but no USB-C outputs.

Lightning is Apple's proprietary technology, so companies need to pay Apple when they use it. This makes it less popular.

Fast charger

Another factor to consider is the charging speed of the backup charger. Redundant charging capacity is measured by voltage and amperage. The current is the amount of electricity flowing from the battery to the connected device, while the voltage is the amount of potential energy. Multiplying the voltage by the intensity of the current you will have. To make the 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 standard fast charging and the battery and cable must support the same charger.

The two most commonly used fast charging standards are Samsung's Adaptive Fast Charging and Qualcomm's Quick Charge. Both of these standards operate in the same way, which increases the voltage rather than increasing the current. Samsung's Fast Charging standard only works with certain Samsung devices, while Qualcomm Quick Charge requires that your device has a compatible Snapdragon chipset. These standards allow you to charge your supported phone up to 50% in 30 minutes.

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

Charging pass-through and wireless charging

There is another problem you need to consider when choosing backup charger. Pass-through charging feature allows you to charge the device connected to the battery, while the battery itself is also charged. If both the phone and the battery are fully charged, this feature is very useful.

Wireless charging is also very popular because it allows you to charge compatible devices without cables by simply putting it on the backup charger. Qi is the dominant standard on Apple and Samsung phones.

Should you buy the phone cover to charge the battery?

If you often forget to bring a backup charger when you need it, you might consider using a battery cover. It combines portability and protection with integrated current so your phone can charge at any time. However, its disadvantage is lower charging capacity than dedicated battery and you cannot charge anything other than that phone.
