When it comes to deciding on the best power banks, there are many factors to consider such as weight, size, capacity, output power and input charging time, number of ports, versatility and ease of operation.
When it comes to the time required to recharge the power bank, the input rating is crucial, the higher the input rating the more quickly the power bank will charge. When it comes to using the power bank to charge other devices, the output rating is the important figure, most power banks offer 5V outputs ranging from 1A to 3A – the higher the rating the faster they can potentially charge your devices. However there are limits, smartphones and other devices will only charge as fast as is safe, this is set by the manufacturers, so higher outputs are generally more useful for tablets and laptops. While we are discussing charging, another feature worth mentioning is passthrough charging. This allows power banks to essentially function as a type of hub so you can simultaneously charge both the power bank itself and other devices, this is incredibly useful as you can just plug everything in at night and charge all your devices plus the power bank at the same time.
The best power banks will have several outputs and will charge all your devices, including smartphones, tablets such as iPads and even notepads. They will also support auto on and off functionality. The more expensive power banks will also offer LCD displays so you can to tell exactly how much capacity is remaining, whereas cheaper units will use a number of led’s instead of a dedicated display. Another useful feature in some power banks is a built-in torch and/or emergency beacon. The ideal power bank will offer the best compromise between capacity and portability, price, fast charging/recharging, and other features such as pass-through charging and LCD displays.
