    I am building an ultra compact HF go box and have been looking at installing an rf amp because the radios output is only 10w. I have seen small 100w amps on ebay and other sites for $100-$200 but do companies make amps that are 30-40w and therefore less drain on the batter

    I would like to know if you have seen small RF amps or have one for sale.

    You're talking about building a "go box". Do you plan on having to carry it or are looking at storing it in the back of a car and driving someplace? It the latter, you might want to think about a 100W 12V Solar Panel Kit Battery Charger like this:

    This would allow you to charge your battery while running the rig and allow you
    to use a bigger amp. In addition, you can cut back on your drive from your exciter thus cutting back on the outpower.

    I found a solar charger that works with lithium iron phosphate batteries' like the bioenno battery. I want to make my box as small as possible so I am going to try and find a cheaper folding solar panel.

    The inexpensive amps I have seen are absolutely not type-accepted and should not be considered.

    There is one called the "Hardrock 50" which will work with under 5 watts drive and has a clean output.
