Powerbank Choice: 3 Main characteristics, to be considered
The prospect of staying with a shrunken smartphone in your hands away from home and a power outlet for many mobile device owners no longer seems scary. They have an external battery - powerbank. And all, who doesn't have it, actively studying the range of available devices, going to buy. In order not to make a mistake and choose a truly practical power bank, worth exploring, what main characteristics to pay attention to, what exactly to consider when choosing.
3 main parameters
A must before purchasing a portable charger (PHU) you need to compare the models available on the market and select the most practical one, taking into account specific operating conditions. Among the technical characteristics, which are decisive, in the matter of choice it is worth noting:
- Battery Type.
- Capacity.
- Current strength.
Let's take a closer look at each point.
Differences by Battery Type
Each power bank contains a battery inside the case., assembled from several individual elements. They come in two types:
- Li-polymer. In such batteries, the role of electrolyte is played by a special polymer with low weight.. Energy density indicator per 1 meals. area is the number, superior to the similar characteristics of ion batteries.
- Li-ion. The main characteristics of these devices include capacity indicator (from 2 500 mAh), recharge cycle life (to 500, to 1 000), weight (about 50 g).
More common are power banks with lithium-ion batteries. Link https://itlook.ua/catalog/power-bank/c80 external batteries of this type are available for order online with delivery throughout Ukraine.
Deciding on the capacity
This parameter indicates that, how many times can the ROM charge the phone before, how he sits down himself. optimally, so that the capacity is enough for 2–4 cycles.
You can understand the performance of a device by mAh. The characteristic must be at least 10 000 (Modern smartphones have batteries from 3 000).
worth considering, that not all declared units are suitable for powering a mobile device. During the operation of the power bank, a certain amount of energy is spent to ensure its operation. To understand more precisely, How many smartphone charging cycles will an external battery last?, can be done using the formula:
Phone battery capacity x 1,5 = X. You need to divide the performance of the power bank by the resulting number.
If you want to purchase an external battery with maximum capacity, then it is worth considering one point: These devices are quite large and heavy., charge longer.
Current strength
For modern ROMs, this parameter varies from 0,5 to 2 BUT. Preference should be given to devices with higher performance. This affects the charging time of the power bank itself., especially if it has a solid capacity and is equipped with several USB- connectors for connecting various devices and gadgets.
When purchasing, you should also consider the current level, supplied by the network power supply to the ROM. It is better to choose models with standard charging parameters. If they are less than the declared characteristics of the smartphone, then the feeding process will take longer.
Useful options
When choosing powerbank, in addition to basic technical characteristics, It's worth paying attention to additional features. Equipment may differ for different models, but many external batteries come with the following features:
- LED flashlight. Some devices also feature a reflector for a brighter glow. The flashlight is turned on and off using the control button;
- charge indicator. Modern power bank models are equipped with an LCD display, which displays information about the power level for all USB channels;
- the presence of several ports with different current parameters. This separation is convenient for connecting gadgets and devices with different technical characteristics.
The most advanced models of external batteries are equipped with built-in solar panels, due to which they are charged not only from the network, providing savings in electricity consumption.
