Inverter question

Oh and also I'll add my problem is while I used 4G wire my strands were small.. the longer your power cable the larger strands you need as the 1000 watt pointed out in its manual.. and my jumpers are 12 foot but just wires not stranded I have 4g stranded with 18g strands but to connect to gators requires welding..

 

My problem with that is I tried it and the reviews all said cig lighter don't work with it because it can only pull 100 and both the tv and ps4 use more individually.. another trucker told me to replace the fuse to allow more but I'm worried like wires get hot so do cig lighters.. to pull to much through it for 10 hours could cause melting and fire.. but also I think I have some crap batterys if i turn truck off it isn't long till I hear it beeping at me about 10-30 minutes varies from time to time

 

Well I think first inverter was hitting a safety amount is why it wouldn't work with ps4 and tv and controller and headset all hooked up its pulling over 100 first inverter rated at 115 output... so bottom line it just had a low output.. now to figure out wifi hotspot lol
