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.

Maybe someone in the community can assist: Dual Battery "Always on 12V" Socket PLB40/CFX345 I have PLB connected to 12V socket and it doesn't appear to be accepting a charge but battery powers all + CFX directly. My vltg is ok. Any thoughts?

Can you charge the battery via solar and power a fridge simultaneously? Will this work with other fridges that run on a 12v socket/plug?

How long does it take to recharge battery using 100W solar or 120V wall plug?

Can I use a 100 watts solar panel with a mppt charge controller to charge the PLB40? this way I can maximize the power from the solar panel and I hope I could run my CFX-50 indefinitely.

Hi, is simultaneous solar and vehicle DC charging possible with the PLB40? I would like to have my roof mounted solar panel connected at all times and charge via vehicle when driving without having to constantly swap the plugs. Thank you :)

Hello, can you guys please give me a link, instead of the generic “in most manufacturer websites” for an Anderson to 8mm adapter. I’m trying to use solar panels to charge this battery.
