What are mobile phone chargers?

Portable chargers save modern electronics.

I think you will agree with me that the weakest link in today's phones are their batteries. Also, the batteries in the tablet are not a source of pride for electronics retailers. Manufacturers try to ensure consumers that their products can work for many hours. Unfortunately, the truth is different, today's phones are very energy intensive. 

Electronic gadgets need frequent charging. An increasing number of phones even require daily charging. Not only that the market can find models that need charging every few hours when operated very intensively. Modern smartphones have many interesting features. Cameras, flashlights, phones can also be radio receivers have a word with many functions. 

These devices are very interesting, but also more and more energy.
It is, therefore always have the charger and power outlet handy.

Banks of energy, of which it is composed?

The unit will charge just connect it to the electronic device (smartphone, tablet, or, for example, a camera). In the majority of mobile phone chargers are very small, you can wear them for example in your pocket. 

Weight average energy of banks varies between 69 and 160 grams. Today, we also slightly heavier device company DOCA. This equipment is fully professional. It has an electronic power meter.

Power banks and their most important parameters.

Very important parameter, power banks, which pay special attention to the capacity of the battery. The size of this is determined within a mile of ampere-hours (mAh). In general, mobile phone chargers oscillate between 2600 - 50 000 mAh. 

We sell a wide range of different models. It is worth considering which model to choose. Contact us and we will help you choose the right model. If you want to protect against emergency situations is sufficient to have a small footprint, for example those with a capacity of 2600 mAh. If you use often with electronic gadgets (electronic games, often playing on your smartphone, you're shooting with a digital camera), you should use the 'monster' of 50 000 mAh

Mobile Phone Charger, consider a model.

Following this path would seem that the higher the portable charger, the better. There is always needed at the moment a large battery charger is sometimes enough to entirely, for example, 2600 mAh. However, whether it is big or small equipment, pay attention to energy losses. Various models of mobile phone chargers have different energy. Tend to be models, where losses are up to 28%, there are also those that are losing only 4% of the energy. Also, energy losses occur when the devices are inappropriate electronic controllers. So, if your bank energy heats up as significant, this means that large energy losses occur.

Part portable charger has two USB outputs. If you want to charge the iPad at such time as is done loading from the network must be connected to the output of 2.1 A. When we use the second USB output or 1 A charging time will be increased twice. Remember, however, that sometimes you use frequently exit! And, as mentioned, the charging time is true is longer but less destroys the battery - less hot. So you may want to load from your computer. The computer has an output of about 0.5 A, the charging is longer but safer for your battery.

Mobile phone chargers, can heat up when charging. The principle is simple, the more heating device the worse. If the temperature during this process exceed 40 degrees, it means that the power bank has lost a lot of energy. You might want to invest in a more expensive but more reliable hardware. If you long to enjoy the reliability of equipment, always choose wisely.


After discharging the portable power banks to load. It should have a means of indicating the level of energy, whether through the LEDs indicating the amount of energy, or are counter. Fill your device can be in two ways. First, connect the battery to the computer and thus charge the energy bank. I recommend this charging method, since the USB output of a computer is only 0.5 A, charging Power bank is longer, but much more friendly to him (your portable charger will no longer serve you). Another way is to use a charging charger from your phone or tablet.
