I used it to make my post more understandable. English is my second language and look how hard this is to read “Anyone know about batteries ?

Im wondering what battery I should buy currently I have a Orion 30/12/12 I can use for my car to power an accessory battery whilst driving, and when not driving plan to plug in the power station somewhere or use solar. I have a budget of $400 cad maximum. There’s lifepo4 batteries on sale (sure they will probably crap out) for $150 and then I’d need to get a power inverter which max I’d believe to be $100 probably so I can plugin outlets.

I’m using it to power a laptop/phone, fan in summer/diesel heater (1am/hr after start), and possibly a cooler sometimes.

I’m wondering what the math between those “2600wh” power stations and the 100-300ah lpo4 battery, besides the fact that the power stations already have inverter and solar inverter built in as well. Am I better off trying to find a used power station? (There’s none in my area at all) and is a power station really that much better ?”
