A MUST have for travel!

I am using the PLB40 to keep our dometic CFX 35 cold when we are not driving. I keep it connected to our plug in the bed of our truck and the CFX35 so that when we are driving I can charge the PLB 40 and then when we stop the PLB 40 takes over. Works like a champ!

Initial Review

A few things after a several 1,300 mile road trips: My setup looks like this in my 4Runner: - Secondary Battery - Always hot 12V outlet in back, connected to the PLB40, connected to a CFX3-45. This way, the cooler would always be on until I run out of battery (which would be a remote possibility). I hope that makes sense. - One trip 1, the problem is that it all worked intermittently and I troubleshooted every single combination down to cords, fuses, my own 4Runner connections, AC/DC, etc. I'm pretty sure that I diagnosed it down to a faulty cord (the one with the Anderson Connector. It's a little disconcerting if you can't trust your systems. -HERE'S THE GREAT NEWS: I sent a note note into Dometic Support, told them I needed a new cord. Three days later I had a whole new PLB40 unit. Hooked everything up, took another trip and it all worked as planned. The CFX functioned continuously for a week. Minimal driving during the day, everything worked!!! Thank you Dometic, for great Customer Support!!!!

Incomplete product

Incomplete product, the battery needs protection for the charging source. I.e. do not drain the car battery. Need Bluetooth and wifi. Needs to be able to be plugged into several charging sources at one time. This battery requires a lot user input/operation and handling

Could be cool but bad quality control

Stopped charging halfway through my first trip with it. Power plug got so hot it physically burned me.

Overall I’m happy, but the PLB40 needs refinement.

I have had the PLB40 for years now and although it has been fairly reliable, it has its flaws, or at least mine does. My biggest complaint is that my screen has always had issues. As soon as I plug it in to charge, the screen slowly disappears. If it ever gets warm at all it seems that’s when the problems happen. And not even extreme, even just mildly warm. I also can’t stand the alarm that won’t stop once the sun goes down and the battery is no longer taking on charge from my solar panel anymore. I wish that was a feature that could be shut off. I wish it would just stop charging and then pick back up when the sun comes up. I do with it had a 120v outlet so I didn’t have to plug an inverter into it for the times I need to plug in a 120v. Mine flashed the battery symbol at random times, last time it happened, it was charged to 100%So yeah, overall, I have been happy. The little bugs just make me nervous while using it because I have absolutely no clue if it’s charging and what the battery percentage is at.
