There are 3 different categories on external power adapters:
1) Adapters which are sending different tensions. They are mostly provided with a special multipolar plug. The purchase of an original-power adapter is absolutely wise!
For the following power adapter it is possible to use surrogate power adapter. But important is the mentioned operating voltage, which is stated in volt (V), this should be identical with the original power adapter as possible. Both sorts of power adapter may provide more power without a problem. The connected device does only admit the needed power. But in the other case, if the power adapter provides less power than it should, the connected device won’t work. The power is mentioned by ampere = ‘’A’’ or milliampere = ‘’mA’’…..1000 mA = 1.0 A.
2) AC- voltage (alternating voltage) power adapter.
These power adapter provide an alternating voltage; the power supply connector has no polarity, this means that you don’t have to pay attention on other values than the right plug, the spend voltage (V) and the maximum power release (mA / A)
3) DC- voltage (direct current) power adapter
These power adapters provide a direct current voltage.
It is important to pay attention not only on the correct form of the power supply plug as also on the polarity.
If you activate a device with the wrong polarity it comes to an error and oftentimes the power adapter destroys! Shall it happen that you search for a surrogate power adapter but don’t know which one is the right one, please do not hesitate to contact us via e-mail (perhaps with a picture of the plug and the info print) we will offer you a keen alternative.
