My car won't start no noise no clicking nothing?

Have a 98 honda accord its been about a month since i've driven it today i tried to crank it and nothing happened i don't get a clicking noise no lights come on or anything i connected to a charge box and when it was done we tried again with the same result please help

I know its annoying getting obvious solutions but sometimes charge boxes don't always do the job have you tried to give your battery a good full charge or tried another battery
