Mobile battery PowerBank

Powerbanks are very popular, we use them more and more often and we increasingly appreciate the possibility of charging an electronic device anywhere, outside the home or work, without access to an electrical outlet. It's a kind of portable power source, an electricity store that allows us to replenish it when our smartphone or tablet is not charged to a high enough level. Powerbanks prevents the mobile device from being completely discharged and helps us avoid unpleasant situations when we lose contact with the world, when we are away from home, during a trip or an important meeting. The verbose products differ in appearance and capacity. Today, we can choose from universal accessories, as well as mobile batteries with a distinctive design. Moreover, it is possible to charge one or more electronic devices with them, which significantly depends on battery capacity. The Powerbank consists of a battery and a cable, with which we connect the mobile device to the battery.

For which devices is the powerbank useful?

Powerbanks have at least two connectors. One is a micro USB for charging the powerbank and the other is a USB that transfers energy from it to the device being charged. Most often we use them to charge smartphones and tablets, i.e. portable devices, which are present in our everyday lives and it is hard to imagine that we could function normally without them. However, we need to know that this is not the only area to which powerbanks are limited. We will also use them to charge cameras, cameras, e-book readers, smartwatches and car navigation. If we use an iPad or iPhone, we will only use the powerbank if we have an adapter with a Lightning connector.

So, with a powerbank you can charge: smartphone, tablet, camera, camera, e-book reader, car navigation, smartphone and game console.

Powerbank capacity, the basic parameter of a portable battery

It is the capacity that we should focus on in the first place when choosing a power bank for everyday use. It is capacity that determines whether we can fully charge one, two or even several devices. A power bank should have enough energy to charge at least two batteries, only then it will be really useful. The minimum capacity of the powerbank is 5000-6000 mAh and should be treated as an absolute standard. It should be remembered that the powerbank is exposed to an automatic energy loss. It usually loses about 20%. Powerbanks available in our shop have a capacity of 1000 mAh to 20000 mAh. So you can adjust them individually to your own needs, range and frequency of use, as well as the devices for which they will be used.

Sizes and materials used for powerbanks

When choosing a power bank, you have to be aware that we will use it primarily outside the home, so often in difficult conditions. It will be exposed to adverse external factors such as low and high temperatures, water and moisture, as well as mechanical damage caused by impact, scratches or falls. It is important that the powerbank housing is robust, tight and well protected against such effects. The powerbanks are manufactured using, among other things, water-resistant plastics. Aluminium works well, which is a lightweight material, but very resistant to water, rust and corrosion. Moreover, portable faucets use non-slip surfaces that prevent them from slipping out of hands.

Powerbank shouldn't be big, either. It has to be a handy gadget that fits in the pocket of a bag, backpack, blouse or trousers. So we pay attention to its compact size and shape. The edges should be rounded so that they are not pointed.
