Wireless charger
The presence in the design of the holder or stand of a special inductive surface through which wireless charging of the installed mobile device is provided.
Wireless charging eliminates the hassle of wires and reduces wear of connectors. Also in this section, the charging power is indicated, expressed in watts (W). Note that when choosing the appropriate device, it is important to make sure that the smartphone also has support for the wireless charging function.
Gadget mount
- Clamp. The simplest mechanical lock: two spring-loaded jaws that compress the device from the sides. The compatibility of those with a specific phone is limited only by the size of the phone; at the same time, the design of the spring jaws itself allows you to adjust the width within certain limits, and in some models, additional adjustment in width is also provided. Thus, the clips are compatible with a large number of gadgets, while they are very simple and inexpensive. The disadvantages of this option include a somewhat lower reliability than, for example, in gravitational devices: the device located in a conventional clamp, usually, is not supported by anything from below.
- Gravity clamp. A latch of this type covers the smartphone on the sides and bottom, while the bottom support works as a trigger sensor: when it goes down under the weight of the gadget, the side jaws converge and compress the device from the sides. Accordingly, to remove the smartphone, you need to slightly lift it. Compatibility in such clamps is also limited only by the size of the device; at the same time, they are noticeably more reliable than conventional clamps, and they are somewhat easier to use, which is why they are more common.
— Magnet. Holder in the form of a strong permanent magnet. Such clamps are very easy to use, as well as reliable and durable (there are no moving parts in the design); in addition, they have no restrictions on the size of the rechargeable gad...get. On the other hand, two other restrictions are relevant for magnets - by weight (it should not be too large) and by materials (not every case, even a metal one, can be effectively magnetized). And although these points are taken into account in many devices with wireless charging, however, the possibility of using it with a specific smartphone (and especially a massive tablet) should be specified separately.
- Proximity sensor (touch clamp). Automatic latch with an electronic sensor that recognizes the proximity of the gadget or the user's hand. “On the way”, the jaws of the latch diverge by themselves, and when the device is installed, they are compressed; when the smartphone is removed, respectively, the clip reacts to the user's hand and disables the fixation. Such holders are very convenient, but relatively complex and expensive; In addition, the mechanism needs power to operate.
Work indicator
An indicator indicating the operation of the charger; in some models it also provides additional information about operating modes, malfunctions, etc. Most often, such a light indicator is in the form of a separate light or a clearly visible backlight system. And additional information can be provided by changing the color of the backlight, by blinking, etc. However, even without these functions, the operation indicator provides additional ease of use. In particular, it allows you to determine whether the charger is receiving power and operating normally - this can be useful when diagnosing various problems.
