Worth money

Bottom line, this is my second power bank for the second car. The first one I have 3 years. No issues. Keep my fridge in the car running for 2-3 days (summer vs winter) without any need for additional charging. Solid and durable produce. Love it.

Great Battery!

I just got a chance to test the PLB40 and was pleased to see it only used 35% of capacity over 18 hours of CFX3 45 fridge use. This includes initial startup. Look forward to more use under other conditions. Very well made also!

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.

For the frig

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 :)

Can you plug one PLB40 in to another PLB40 to double the amount of time it will power a cooler?

I bought a dometic 95 CFX , but got stolen now I still have my dometic plb 40, my question is how can I plug a coffe machine it has no way where to plug it? Thanks

My screen display went out. I have used this 4 times. How do I get in touch with support?

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.

Does it have a USB-C output?
