Almost any digital gadget requires periodic replenishment of the energy spent. When buying a phone, camera or tablet, you do not need to purchase a special device for such purposes, since it is always included in the kit. Nevertheless, in the process of active operation of several units of such equipment, confusion may arise. In addition, taking a gadget with you on a trip with a service headset is quite expensive and inconvenient. A universal network charger capable of replenishing the energy supply of various types of digital equipment can become a solution to the problem. Of course, each product has its own range of devices suitable for servicing, but even standard models are quite suitable for most portable devices.
Main characteristics
The main operational parameter that you should pay attention to when choosing such devices is the current strength. The standard range varies from 1000 to 3000 mA. So, for small mobile devices, players, and certain categories of digital cameras, a network charger with a current strength of 1000 mA is suitable. For tablets, laptops and other types of equipment that use more resources, you should purchase such accessories with a potential of at least 2000 mA. It is important to consider that the charge speed depends on the number of amperes. Other characteristics relate to the weight, dimensions and configuration of the interface for connection. These parameters are quite diverse, so every user can find the best option on the market for the needs of their portable gadgets.
USB Charger
The idea of combining the small size and function of a universal charger has long been mastered by manufacturers of digital technology. In particular, attempts have been made to create multi-plug models that fit multiple devices. However, the use of such devices did not guarantee complete independence from individual charges. The solution was found during the widespread adoption of the USB interface. Both mobile devices with cameras and tablets with laptops were supplied with a connector. So there was a network charger, the USB port of which provided the ability to service all models of equipment with a similar interface. Of course, this gave only the possibility of a correct connection, because the charging intensity and, on the whole, the possibility of its implementation depended on the electrical compatibility. Modern USB-chargers for convenience are equipped with whole groups of connectors, which allows you to recharge several gadgets with energy at the same time.
Types of devices
There are no special classifications, but it is possible to conditionally divide the devices according to their purpose. The most common are network chargers for phones, the features of which include the presence of a micro-USB interface. The user in this case receives the connector and the connector itself. It is important to note that charging time also depends on connecting cables and adapters. The better the wire, the faster the process of replenishing the feed element.
Also worth noting are chargers for more energy-demanding equipment. This is a segment in which tablets, powerful cameras, some laptop models, etc. are presented. In terms of design, they do not stand out, but the current in this case can reach 3000 mA. However, the network charger for the tablet may be limited to 2000 mA - another thing is that the process will take longer.
Car Chargers
To begin with, it is worth saying that the very principle of an alternative charger arose from the need to free the user from a conventional power supply. Most efficiently, solar batteries and external batteries perform this task . Network devices focus on another aspect of ergonomics, but car models of this type combine two concepts. The fact is that the network charger can work from on-board wiring 12V directly in the car. Of course, compared to 220V, this is not much, and the process efficiency may be minimal, but as an additional feature this option suits many. Especially when it comes to emergency situations.
LG Model Reviews
Devices of this brand are praised by many users for the quality of the case, the stability of the main function and attractive appearance. Some LG models can also be used as a means of synchronizing a mobile device with a PC. The safety concern of the manufacturer is also noted separately. As users themselves emphasize, the microcontroller independently stops the power supply if there are signs of overheating. A similar reaction is provided in cases where the network charger works with strong fluctuations in voltage. As a result, the device extends its operational life and minimizes the risks of unpleasant consequences for the power grid.
Samsung Model Reviews
Samsung products are well known in the mobile market. For its smartphones, for example, the manufacturer produces multifunctional and easy-to-use chargers. Almost all models of this line are provided with a micro-USB cable. According to the owners of such accessories, they are characterized by a high speed of replenishing battery energy and durability. Of course, the Samsung AC charger is not only suitable for products of this brand, but also applies to portable equipment from other manufacturers. There are many positive reviews from modem owners who also use Korean chargers. In the operation of such devices, care and stability are especially important, which is provided by products from Samsung developers.
Sony Model Reviews
As one of the leaders in the market of smartphone manufacturers, the manufacturer Sony also focuses primarily on servicing this kind of device. In particular, users of Xperia devices note the high efficiency of chargers, which is combined with reliability and safety. Protection against overheating and power surges is a mandatory function of such devices. Many note the ergonomic advantages that a Japanese charger has. The network adapter is notable for its easy-to-use housing and a long cable - on average, about 80 cm. The disadvantages of such devices are the high cost. So, the basic models are estimated at 800–1000 rubles.
Conclusion
Despite the seemingly modest function that the chargers perform, every little thing in their design has significant practical value. Replenishment of the energy of the battery today is not complete without special devices, so manufacturers strive to make them as convenient as possible. For this reason, the network charger is sometimes supplemented with auxiliary functions. For example, few of the users of modern gadgets can be surprised at the possibility of connecting a mobile device and a computer through communication systems of chargers. In addition, protection and energy conservation tools are being developed. Many manufacturers strive not only to give charging devices optimal indicators of voltage and current strength, but also to make them universal. As a result, the USB interface itself is developing, as evidenced by the spread of its modern configurations, in particular the micro version.
