Power bank is a gadget that has become a staple for many of us – we use it not only while we’re on the go. It comes in handy when you’re at work or at school, too. You can also use it when going for a long walk or heading for a weekend trip. Power banks are good not only when you need to recharge your phone –  high capacity models can even charge a laptop or a portable console!

In this article you will find out:

  • when high capacity power banks are especially useful,
  • what are the advantages of the best power banks,
  • what models you may want to explore in Battery Empire.

The best power banks and when to use them

If you’re looking for a portable power bank to recharge your phone in case of emergency, you will need a model with a capacity of up to 10000 mAh. Such a device is perfectly enough to extend the working time of your smartphone or other small electronic devices (e.g. wireless earphones or a speaker). If you want to choose a power bank with a capacity of 20000 mAh or more, you will be able to use it for other equipment, too. What exactly do we mean by this?

Power bank  with a capacity higher than 20000 mAh is a staple for all those who work outdoors with electronic devices. If you need constant access to your laptop, but don’t always have access to the mains, a high capacity power bank  is exactly what you might be looking for. It will also be useful when  you keep using a few phones or other devices  (e.g. cameras) – this makes a power bank an essential accessory for influencers or those who work with multimedia.

A portable power bank with a capacity over 20000 mAh is a good idea also when you’re out in the open and cannot access a source of electricity for a longer time. If you’re going on a faraway trip into the wild to shoot photos or movies, you should definitely have a high capacity power bank with you.

The advantages of a high capacity power bank

High capacity means you can recharge a laptop or other advanced devices, but there’s more to it. The best portable power banks come with a  fast charging option (e.g. Qualcomm Quick Charge), so you can quickly replenish virtually any battery. Most powerful power banks have different USB ports, which allows you to charge several devices at the same time.

When looking for a new, high-capacity power bank, make sure you pick a product by a well-known brand. Take some time to explore the opinions about  the construction and durability. Remember, portable power banks often have to withstand difficult conditions and are exposed to a variety of factors. It’s good if your device is resistant to mechanical damage and weather.
