Can the battery capacity (mAh) be greater?

It is possible to use higher capacity batteries. The battery capacity is expressed in miles of ampere-hours (mAh), the higher the value of the capacity, e.g. 3000 mAh, the longer the working time can be achieved with one battery charge, which increases our mobility and efficiency.

How to choose Power Bank?

  1. Battery capacity in the phone The most important thing we need to check is the battery capacity in our phones, and this can vary from just over 1000 mAh to as much as 4000 mAh. Please note that there is an inevitable loss of energy during the charging process, which can reduce the actual performance of the Power Bank by up to 75%. This is a completely natural phenomenon and must be taken into account.
  2. Power Bank for smartphones - What parameters to consider? If you have a phone that can charge quickly, it's worth choosing a power supply that supports 2.1A or QC 3.0 charging, so you can charge up to twice as fast as other models. Please note, however, that the quick charge option is useless if the phone is not compatible with it.

Power bank - the perfect device for any travel

Does the battery indicator flash at the wrong moment? Your charger is not efficient enough? In such situations, it is worth having a good power bank with you! Use the cable to connect your power bank to your phone and power up the battery without a power socket. A power bank is an ideal companion for every journey. You can use it to charge smartphones, notebooks, smartwatches, game consoles, MP3 and MP4 players, car navigation and all other devices which have a suitable port. The modern Jump Starter power bank will start the engine in your car thanks to its high starting power! Discover all the advantages of external batteries and buy the best power bank with fast charging function.

In the Battery Empire shop, you will find a wide range of high quality and high-performance power banks. The devices we present are equipped with cells from renowned manufacturers, which will ensure mobility and freedom of work. Powerbanks differ not only in capacity but also in additional functions, number of ports, performance, design, size and weight. In our assortment, you will find external batteries of renowned manufacturers. This is the best guarantee of excellent quality and 100% satisfaction with use.

Powerbanks can be divided into three basic categories:

● lightweight and compact models that are ideal for charging your phone on the go,

● flexible models with multiple ports,

● high-performance devices for special tasks.

Important features in a good power bank

When choosing a good power bank, it is essential to pay attention to the capacity offered. Also, check the energy density of the device that will be powered by the external battery. Every power bank has a certain capacity, which is created by converting the low voltage of the battery cell to the 5 volts required for the chargers. For most devices, the actual capacity is 70-90% of the specified capacity. The actual capacity of a 10,000 mAh power bank is between 7000 and 9000 mAh. If your smartphone has a 4000 mAh battery, be sure to choose a power bank with a higher capacity. Check out our shop and buy a power bank with fast charging function with a capacity of up to 30,000 mAh!

Undoubtedly, an external battery will make you independent of the power grid and will power your mobile device wherever you are. Depending on the model, you can use it to charge your smartphone, tablet or notebook or several devices at the same time. A power bank with a 12-volt socket, i.e. an additional DC input, can be used to charge even large and demanding equipment.

The basic versions of power banks usually offer one input for connecting a suitable USB cable. Larger models have up to four ports, so you can charge multiple devices at the same time. A great example is Green Cell's Power Play Ultra Charge model with four USB inputs. The power bank features fast charging and can be successfully used to fill the batteries with your laptop, Macbook, iPad, iPhone, Nintendo Switch and more. In addition to connectors in the widely used USB 2.0 standard, good power banks offer a USB-C interface type. In some models, you will also find a Schuko socket, to which you can connect electrical devices up to 100 watts.

Wireless charging - buy a battery power bank and forget of your faulty charger

If you want to charge your mobile device without a cable, choose a power bank with wireless charging. Such an option is offered by the external battery of the brand Xiaomi, among others.
