low power router/switch needed or?

[Westbranch]

I have a NetGear router that will run on 12V DC 1A from a power brick..

I am going to use it on 120V AC power for the interim but would like to use a lower power device to hook into 2 separate Classics for (simultaneous) monitoring over Cat5 connection, hooking both into one computer .

I am looking for suggestions for a lower power replacement, doesn't have to be a router, just use less power, as the connection will be hardwired.

thanks

so far found a Linksys switch at 6 watts, still looking.

One suggestion was to use a USB to Cat5 dongle. 
Anyone know if this will work? 
Can the PC 'see' both units at the same time one via USB and one via LAN?

ADD:  reviews I just read were for MacAir and Android systems though listed most of the MS OS packages up to W8

wb,
Forget the USB to Enet dongle, waste of time and money.
What you should look for is an ethernet hub, 3,4, or 5 ports NOT a switch or router of any kind.
My 4 port hub connecting two Classics, OB AXS and Linksys WET54G bridge, uses under 90ma at 12v,
the wart is rated 12v at 250ma.
