Cable length

The length of the cable used to connect the surge protector to the network.

The longer the cable, the farther from the outlet you can install the device. On the other hand, a long cable can be inconvenient over short distances. Models on a coil are deprived of this drawback (see "Type"), this moment is compensated by the actual presence of the coil, but they differ in large dimensions and heavy weight. So when choosing, it is far from always worth chasing the maximum length of the wire.

USB A

The number of USB ports for charging, provided in the design of the surge protector.

Such ports do not perform any other function than powering and charging external devices such as smartphones or tablets. The presence of such connectors in the surge protector can be especially convenient when there is no “230-to-USB” adapter at hand, and there are few USB ports in a computer or laptop and using them for charging is “an unaffordable luxury”.

Max. charging current

The current output by a USB connector when a charging gadget is connected to it.

The higher the current, the faster the battery can charge. However, when choosing, note that in order to use a high current strength, the connected device must also support it. Basically there are USB with a current strength of 2.1 A, 2.4 A and 3 A.

It is also worth noting that when using several USB ports at the same time, the current strength is significantly reduced.

Power (with 1 device)

The maximum power that a USB port can produce when connecting only one gadget.

Higher power output speeds up the charging process. At the same time, there are a number of nuances associated with this parameter. Firstly, the appropriate power must be supported not only by the port, but also by the gadget being charged - otherwise the speed of the process will be limited by the characteristics of the gadget. Secondly, to take full advantage of the capabilities, you may need to support not only the appropriate charging power, but also a specific fast charging technology. Thirdly, in filters with several charging connectors, the maximum power per device can only be achieved if the other ports are not used.
