I have a wrt54g with dd-wrt v24 sp2. I live off grid and power generation is currently limited and I try to minimize it's use. I am searching to find what ranges of voltage and amperage the wrt54g can handle. Read on the forum it can deal with 6 to 17 volts. Somewhere I have read that amperage draw is only what a device needs so a relatively higher amperage availability shouldn't bother. I have a 12v/ 5amp automotive power supply so as to go directly from DC To DC rather than DC/AC/DC which I'm thinking robs a little power in conversion. I can also bypass the inverter. Any insight if the wrt54g can tolerate the excess amperage? Or lesser amperage than the 1000ma supplied by the OEM supply?
