Hi! I also couldn't decide between a thermoelectric and compressor cooler before, but I finally decided on the
electric cooler. It keeps the cool even in the heat, and, what was important for me, it doesn't drain the battery too quickly. It has a system that doesn't overload the battery, so I can use it on trips without any problems. The only thing is that if it's very hot, it can take a little longer to cool, but it still works great.
