3C power supply, input 100-240V AC, output 12V 2.5A, suitable for routers below 12V 2.5A,Adopt 5.5×2.1 interface, full protection.
The choice of router power supply:
A. If you want the router to be stable and uninterrupted and use it for a long time, you should first choose a certified adapter, such as 3C/ UL and other certified power supplies use high-quality components because of their high standards, and they also add anti-interference and filtering components, with stable output voltage and low current ripple, which can provide the router with an optimal working environment.
B. You need to choose the same output voltage. For example, if the router needs 12 volts, it must be equipped with a 12 volt adapter.
C. Need to choose the same or larger output current(Don’t worry about burning the router when it’s too big. The router consumes current on demand. If you don’t use that much, it’s just reserved in the adapter. The router will not always have the maximum current.)For example, the router is originally 12 volts and 1 amp, and the adaptation is at least 1 amp. Of course, it is better to choose a larger output of 1.5 amps or 2 amps. Because the reserve power is large, the router occasionally transmits a relatively high-power signal adapter It can also guarantee the power supply, and the adapter will be more durable if the margin is large and the heat is small.
D. The current is not as large as possible. Although it will not burn the router, the high-current adapter is expensive, so there is no need to waste too much to choose a larger one.
