One of the things that you do not like at all when you are on vacation is having the restrictions of the autonomy that the smartphone or tablet you use has. If we are very aware, it is possible to be unable to use the device in question at the worst possible time. Well, thanks to cheap external batteries this is no longer a problem since they are a lifesaver and, also, very effective.
These accessories are very useful devices since inside they include a waterproof battery that conserves the charge until the cable is connected to use them, so they are ideal to carry them in the backpack as in the pocket of the jacket. In this way, whether sitting at a bar or on the rock you are sitting on when you go hiking in the countryside. The point is that, once they are used, going on vacation without one of these accessories is not the same.
Minimal charge for cheap external batteries?
If we take as a reference that current smartphones, both mid-range and high-end, have a battery that is between 4,000 and 4,500 mAh, the ideal is that the model selected allows the component to be filled in at least a couple of occasions for not having restrictions of any kind when using the smartphone to play games or watch series in any place where there is an Internet connection.
Therefore, the brand that we consider ideal is the following: 10,000 mAh , since with it the aforementioned is solved and, due to the good miniaturization that these types of devices currently have, the dimensions and weight of external batteries The cheap ones we are talking about are more than adequate to carry them from one place to another without any hassle. In addition, as we will indicate later, what you currently have to pay for these models is not exactly unreasonable .
Connectivity, key in these accessories
This is very important when buying one of these accessories, since at least one USB type A input must be included, in order to use the cable that is included with the smartphone or tablet. But, the truth is that the inclusion of a second port seems essential today in case you need to charge two devices at the same time (if one of them is type C , better than better since all the needs that are they can have). The fact is that here the more the better, it is fulfilled.
It is important to check that the charging port of the cheap external battery itself must be USB, since otherwise you can have compatibility problems. In addition, if this is the case, in the case of not having the original cable at hand, it is always possible to get one without much difficulty.
By the way, we must not fail to check that different protection technologies are included so that the charging of smartphones and tablets does not have any danger. An example are those of overvoltages or temperature control. It is also positive that there are different information LEDs to know at all times how much charge the accessory has left and not have unpleasant surprises.
