Portable detectors include detectors that can be powered by built-in or rechargeable batteries (see below); this allows them to be used regardless of whether there is a power outlet nearby. But the shape and size of such devices can be different; in fact, this means that not all such models are convenient for constant carrying.
Types of power supply provided in the design of the counterfeit detector. There are models that have several types of power supply — usually they combine the mains with built-in or a rechargeable batteries.
—
Mains powered. Powered by a conventional 230 V power outlets. Such devices have an almost unlimited operating time (as long as there is mains power) and can be equipped with any set of additional functions. On the other hand, the freedom of movement is limited by the availability of outlets and the length of the power cord.
—
Removable battery. Powered by replaceable elements of a standard size — for example, AA-battery. Such elements can be produced both in the disposable type and in the form of rechargeable batteries, they allow you to work regardless of the outlet, and an empty battery can be quickly and easily replaced with a charged one (unlike a built-in battery — see below). Among the cons of this option, it is the need of additional expenses — disposable batteries are inexpensive, but you still have to buy them regularly, and you will have to spend a lot on batteries with a charger.
—
Built-in battery. In this case, it means counterfeit detector operates with original battery — often non-removable. Compared to the removable batteries described above, this option is convenient in that the power does not have to be purchased sepa
...rately. On the other hand, an empty battery cannot be quickly replaced — the only option is to charge it, and this takes time.
— Car charger (12 V). Powered by a 12-volt car on-board power circuit, connected to the car charger (or a separate power socket with the same connector). According to the main features, it is similar to the connection to conventional mains described above. This option may come in handy if the detector is intended to be used frequently in the car, for example, in a mobile store. It should be noted that models with this type of power supply are not always packed with a car charger — sometimes it needs to be purchased separately.
