What is a power bank?
A power bank is a portable charger designed to recharge your electronic gadgets when you’re on the move. Ranging in size from slim, pocket-sized devices up to larger, higher-capacity power banks – they can be used to charge cell phones, tablets, GoPros, portable speakers, cameras and even laptops.
As technology keeps on improving, we are increasingly finding that running out of battery can be a big problem. Smartphones now come with large, energy-sapping screens, popular apps like Waze, Tinder and Google Maps all place large drains on our batteries.
That’s where purchasing a portable charger can really be a life-saver! If you’re traveling or out and about and you won’t have a chance to recharge your device, simply plug in your power bank and charge it right back up again.
How to charge a power bank?
Most power banks and portable chargers come with a USB input port which you can use to connect to a wall socket, or a USB port on your computer to charge their batteries. Some also come with a supplied adaptor to be able to plug into a wall socket. There are some products that use a micro, or mini-USB socket to charge their batteries.
What are the different types of power banks?
Phone case chargers
Power banks come in many different shapes and sizes to suit different budgets and power needs. There are portable chargers for just about every device. Most people use power banks for their cell phones, tablets, and laptops.
New external chargers are coming out every day with new technologies. Some portable chargers work by harnessing solar energy from the sun while others double as a case that also charges your phone.
How long does it take to charge a power bank?
This is largely dictated by the size of your power bank’s batteries. The larger the capacity of the power bank you decide to purchase, the longer it may take to charge. For instance, a smaller portable charger with a capacity of 1500mAh will charge in about the same time as a typical smartphone. A larger device suitable for laptops may take up to 4 times as long. Charging via a wall socket is also generally quicker than connecting your power bank to the USB port of your computer.

How many times can a Power Bank charge my device?
This comes down to the capacity of your device and the power bank/portable charger. A power bank is measured by its capacity, which is rated in mAh (milli Ampere hour.) Generally, the higher the mAh rating of your power bank or portable charger, the more power it will have to recharge your devices. A good rule of thumb is to look at the mAh rating of the devices you want to charge, and purchase a power bank that has an equal rating (preferably higher).
