In most cases, people going to buy a power bank face the same questions: Which to choose an overbank? What to look for?
I’ll try to give some tips on choosing a very bank based on your needs and what to look
for. First of all, you should think about whether you really need a storm bank?

And only if you really need it, start choosing the right model for you. And so, what to pay attention to when choosing a power bank:

 

6 Tips: How to Choose The Right Power Bank

Compatibility

Compatibility

Be sure to note that the input voltage required to charge your devices is the same as the chosen power bank model’s output voltage. You can see it either on the network charger equipped with your device or in the accompanying instructions. Most modern gadgets such as smartphones, tablets, action cameras, GPS navigators, etc., the most common voltage will be 5B DC (5V DC) that fits USB specifications. The current force requirements are usually not as stringent. So, if you connect the device with a requirement for a current less than can provide a believe bank, nothing terrible will happen; the charge controller will not allow the excess of the charge. On the contrary, if you connect a device that requires more current to an overbank or charger, in the output parameters of which the maximum current is declared below the required, for example, a tablet that consumes current in 2A in time for the charge to reach 1A, either the charging process will be longer, or the device will not be charged at all due to lack of power. However, usually, this happens only with particular devices like the iPad.

 

Manufacturer

Manufacturer

Choosing a manufacturer, first of all, you should keep in mind that Power Bank is a high-tech device, which consists of lithium-ion batteries and certain protective systems not to destroy your gadget, not to burn yourself and please you with long-term and trouble-free work.
That’s why Power Bank is often called not just a battery but an “autonomous charger.”
Often buyers make the same mistake – buy chargers from unknown manufacturers, which do not even label their products with logos, flattered by the low
price. Unfortunately, in such cases, the real capacity will often be several times smaller than stated.
So, the first thing you need to choose is well-known
manufacturers. But there is a downside: the more popular a model, the more likely it will be forged.

 

Capacity

Next, you need to determine the required capacity of the bank. Think about how many charge cycles your device should provide? And multiply this figure by the battery capacity of your device and by the factor of 1.5. I do not believe those tables where divide the bank’s capacity on the battery capacity.
A 10,000mah can never charge three times a smartphone with a 3100mAh battery.

After all, the voltage of the bank’s batteries, in most cases, is 3.7B (or close to it) and depending on the current level of battery charge, it may differ in a larger or smaller
way. And so first must be upgraded to 5B, to meet the standard USB, a special scheme. Then it will flow through the cable into your smartphone, after which the charge controller in the smartphone will again reduce it to the required for the immediate charge of the battery. And at each of these stages, there will be big or smaller losses.

 

Functionality

It can also be functional. Here’s a small list of convenient, but
in my opinion, non-binding features: – Second USB port.
– AN LED flashlight can be useful to you, for example, to make it easier to find a slot charging your smartphone or tablet in the dark.
– a digital indicator of the level of charge because it can more accurately estimate the exact percentage of the charge level of the pervert back than on flashing LEDs.

 

Weight and size

Weight and size

The size and weight of the bank are proportional to its capacity. The more capacity the batteries are installed in the very bank, the greater its weight and size. Also affected by the weight and size of the battery installed in it, the lithium-ion battery (Li-ion) will be slightly larger and slightly heavier than a lithium-polymer battery (lipo) battery of a similar capacity.
The weight will also be affected by the material from which the body of the power bank is made: the aluminium body of the bank will be heavier than the similar one from
plastic.
It is also necessary to consider the correspondence of the stated capacity and weight of the
bank. Often it makes it easy to identify the majority of over banks with clearly inflated “Chinese optimism” capacity because a bank with a capacity of about 10,000mAh will weigh 200-260g. And twice the capacity (20,000mAh) respectively, about twice as heavy. So if the capacity is clearly not suitable for weight – do not buy such a power bank.
However, the weight does not guarantee that inside are not batteries with a capacity less than indicated in the characteristics, but at least, it makes it easy to identify a clear discrepancy in the
characteristics.

 

Design

The overbank design can also play not an unimportant role in the choice because someone is important characteristics, and for someone,” he is red!”© http://bash.im/quote/394311 so there are released not only different colours and shades but also different shapes, up to the characters of anime films, for example, Poverbank the character of the anime film”My NeighborTotoro ” (My Neighbor Totoro). Different people have different needs, including in the riverbanks: someone needs a small new bank, which they carry with them”just in case” such as more lavo 2500mAh, thin, light, easy to fit in a purse, and which will easily help in the situation”home will get soon, the phone sits down, and I wait for an important call” and which will easily replenish the charge of your smartphone to a level sufficient to avoid missing an important call. Well, for someone, you need to repeatedly charge their gadgets away from the outlet, for example, in the campaign to charge GPS-navigator, radio, etc. You here already need more capacious models, such as Teclast T200E at 20,000mAh, or even a few.
