I need two rechargeable battery packs that I can charge at any power outlet. I have a pretty good idea about electrical safety and believe that I can fit each into its own backpack for transport to and from power sources. Each batter pack needs to last for around 12 hours at 150-300 watts. I need to be able to charge it in around 8 hours and then it needs to last around that same amount of time if not longer. If need be I can make 3 packs so I can charge two at a time while one is in use.
These battery packs are going to power a thermo electric cooler and a computer fan while I am living in my car. The computer fan circulates air while I'm sleeping since I cant idle the car all night just to circulate air and I dont want to roll my windows down since its a small car and anyone can easily reach inside to rob me. The thermo electric cooler is to keep my supplements cool and keep them from degrading due to getting to hot. Amino acids and other supplements are delicate and decline in potency over time when not kept cool.
I know that home depot sells 6 volt rechargeable lithium light ballast batteries but im not sure if these are suitable for long term daily use.
