For common chargers, the input power is 100-240 V and 50/60 Hz. The designation Hz describes the frequency from the mains.

For this purpose, the USB cable is simply connected to a USB interface, for example PCor laptopand connected to the tablet or smartphone with the micro USB interface. Already photos, videos and music can be transferred to the respective terminal. It is particularly convenient that the paired terminal is charged when connected to a laptop or PC at the same time.

USB chargers with quick charge function
A quite new variant in this segment are chargers with a quick charge function. This feature has the advantage that tablet, smartphone, ebook and Co. can be charged significantly faster than with a classic charger. The charging current is kept very high in this variant, so that the charging time is enormously shortened. Those who decide for this variant should first make sure that the battery of the respective device has a fast-charging function. If this is not the case, this type of USB charger can not be used either.

Important safety equipment: The control electronics
Modern chargers are now all equipped with a control electronics, which prevents the battery is still charged, although it is already full. This avoids damage to the battery. If a non-manufacturer USB charger is purchased, it should be ensured that the new model also has control electronics. Thus, the respective terminal can safely remain connected to the charger all night without damaging the battery.

Pay attention to different connector types
If you want to buy a new USB charger for a particular device, you should definitely pay attention to the type of plug. Small devices usually have instead of a USB port, a mini-USB port, which, as the name suggests, something smaller fails. Smartphones and digital cameras usually have a micro or a mini-USB port. If you are unfamiliar with this area and you are not sure which type of plug is needed, you should take a look at the operating instructions of the device. Here is usually listed, which plug type it is.

Well-known manufacturer or NoName product?
Whether the USB charger comes from a known manufacturer or is a so-called NoName product is absolutely irrelevant. The important thing is that the strength, voltage and current flow are right. However, it should always be noted whether a CE mark for tested safety can be found on the housing. This ensures safe handling. All electrical appliances sold in the EU must have this mark. If this symbol does not exist, the charger should not be used.
