In some countries like Greece(there I live and) we have really usually power failures (I don’t know if you have the same problem in USA)
That’s a big problem especially when you are working on the computer.
To avoid that you can use a laptop , tablet or your smartphone , but what about the internet connection ?
Step 1: Watch the Video

Step 2: Battery Pack
To solve this problem I make a common AA
batteries power supply for my internet router !
In my case I need 12 volts and 1 amp, so i need 8 AA batteries (8*1.5 = 12 V)
To connect all thaws batteries together I have joined together two battery packs from old R/C cars radio controllers
Step 3: Connections
Now for connecting the self-made battery pack with the router I chose this wire that from the one side has two alligator clips and from the other it fits nicely on the router .
(You just have to connect the positive side of the battery pack to the red clip and the black to the negative)
Step 4: That's It
And that's it ! Now you can enjoy internet connection whit Ethernet cable or wireless with Wi-Fi in any situation like power failure !
