After all, everyone has a smartphone Navigator, where you can find your way even in the forest, where there is no cellular connection. Now imagine that you get lost, as the smartphone "safely" villages. Road in the forest can accurately find only a very few, who know the terrain.

Power Bank: principle and an external energy storage device

In appearance, sometimes even impossible to understand what it is. Believed bank may have different shapes, but all have the internal structure similar accessories almost equally. Inside the plastic or metal body is located one or several batteries in a certain capacity. On the body there is a socket for charging (generally micro USB), and the output jack (jacks) - USB-outs. They charge the device connects.

Besides the number of ports, external batteries have capacitive characteristics, the current power. The battery itself is also different, as well as on mobile phones, but on this we will focus a bit more detail later.

External Battery Power Bank: its positive and negative qualities

Power Bank merits of course greater than the disadvantages. Let's consider them in detail. Let's start with the advantages of using an external laptop battery, including:

• Compatibility with gadget and the number of charging ports;
• Battery type Power Bank;
• capacity;
• Output current;
• Additional features that are equipped with an external battery;
• size and weight;
• design.

Let's try to analyze in detail each item to the reader selection algorithm was understandable.

How to Choose a Power Bank for compatibility and number of ports

The main thing you should look for when choosing - Compatibility external battery and the voltage of the gadget - they must match. Otherwise inevitable problem with a phone or tablet, until its failure and even battery ignition.

The number of ports. Here we must proceed from the requirements of the Bank believe. If you have one device and is scheduled to sole use, it is worth paying attention to the external battery with one port - their lower cost. It is believed Banks with multiple ports, allowing to charge two devices at the same time, and more.

How to Choose a Power Bank for your phone or tablet on battery type

Banks believe equipped with two types of batteries: lithium-ion (Li-ion) and lithium polymer (Li-Pol). We will understand, what is the difference between them.

Lithium-ion - shaped like a penlight batteries. They have a lower cost, but it affects the durability. These batteries can withstand about 1000 cycles "charge / discharge". Self-discharge them higher than that of lithium polymer counterparts.

Lithium polymer - plastic battery, which in the production of the manufacturer can be given any shape. By all indications Li-Pol better than Li-ion. Self-discharge is virtually absent, and as for the durability, these batteries withstand from 1000 to 5000 "charge / discharge" cycles. Naturally, the banks believe in such batteries have a higher cost.

The capacity of the Bank to believe: what does it affect

Before as choose to believe the Bank smartphone or tablet to capacity, should make some some simple calculations. For example, you often go on business trips. During a trip you need to charge your smartphone 2-3. We look at the battery capacity gadget (take for example 2500 mA / h). Then purchased an external battery capacity should be at least 9000 mA / h. Consider how to obtain this figure. 2500 mA / h (smartphone battery capacity) × 3 (number of chargings) 2500. The latter figure is added due to the fact that every Power Bank is automatic, does not permit the full discharge of its batteries. 2500 mA / h - this is precisely the "cushion" that allows the gadget to charge for the third time in full.

What is an external battery for your phone better by the output amperage

Before you choose to believe the Bank on this parameter, note the "native" gadget charger - on it the permissible current. In simple terms, the higher the output current, the charge will be made faster. However, a surplus on this indicator to quickly bring down the battery of the gadget.

• support fast charging technology;
• solar panels, allowing an external battery to obtain energy from light.

Of course, the presence of additional features increases the cost. If you are not afraid, you can consider these options.

Which to choose Power Bank, considering the size and weight

These parameters will depend on the selected capacity external battery. External battery large capacity will have a large size; weight - a physicist from it can not escape.
