according to the reviews the hot logic uses 4 amps and takes hours to heat up food. Thats too long when your hungry. If you got alot of time to wait for the food to be ready or need something that is low amp usage it might work for you.
My advice is get a roadpro lunch bucket (use 12 amps) I been using the one I bought in 2013 and its still running perfectly (minus the broken latch) . I can't wait an hour or more for the food to be ready. A can of ravioli,chili,soup or beef stew will be ready in 15 minutes. To heat up some fishsticks or taquitos takes about 30 minutes.
It might use about 4 to 5 amps in the 15 minutes it cooks, not bad. Its my only means of heating up food and never let me down. It doesnt have an on/off switch, when you plug in it starts heating up, I just set a timer for 15 minutes and unplug when its done. If you forget and leave it on, it wont burn anything down, it will just drain your battery. It has a seal so if it tips over it wont spill as long as the latch is working.
If you get the hot logic, I would replace the 12 volt connector with an xt60 or some other connector that can handle high amps. I read some reviews of the 12 volt connector heating up and melting.
I was also thinking about getting a hot logic because it looks like you can heat up more food then the roadpro, but ultimately I like my food to be ready fast.
roadpro lunch bucket. I use aluminum foil to line the cooker and put the food on there, never makes a mess. Notice how I cut the wire short and use an xt60 connector (handle 60 amps) instead of the cheap 12 volt adapter it came with ( they arent design to handle 12 amps and heat up tremendously). I cut the wire short because they used 14 gauge wire (maybe 16 gauge) and it gets very warm while in use, too thin and long for 12 amps.
