Glossary
Fault detection
A diagnostic system capable of detecting faulty batteries, disconnecting them from power and notifying the user. The fault detection function is useful not only for checking the performance as such: a battery malfunction that is not detected in time is fraught with equipment damage, and in some cases even fires.
USB output charging gadgets
The ability to use the charger to charge portable electronics - smartphones, tablets, players, etc. As a rule, for this, a USB port is provided in the design, for connection to which an appropriate cable is required; in fact, you can charge from such a device not only mobile gadgets, but also any equipment that can be powered from USB. True, it is worth noting that some manufacturers do not recommend using third-party devices for their equipment if they are not officially approved.
Mains plug on cable
Chargers with a plug for connecting to a socket on the tip of the mains cable. Models with a plug on the wire provide freedom of placement of the “charger” (especially in cramped free space near the outlet). So that the cable does not get tangled at hand, in many models it is made removable, which makes it easy to store the charger.
