Review: I was initially frustrated because the battery stopped charging and I couldn’t get a response through desertcart messaging. I use this thing all the time and it’s always been great, so it was disappointing. Early one morning I finally got through to customer service after about a 20 minute wait and spoke with Brittiany. She was awesome. Took my info, reviewed the issue, and set up a replacement without making it a headache. I’ve never had a problem with this battery until now, and they handled it the right way. Good product, good company I’ll keep buying from them.
Review: Despite what all reviews may say, this battery pack did not get me through a weekend trip off the grid. That being said, it did work hard at powering my Dometic CFX 55. I wanted to stress test the battery and found that even with the cooler battery protection on HIGH, and the temperature at 50 degrees F, and driving for an hour or so, that I left my campsite Sunday morning with a low battery alarm. I used the cooler/battery above 6,000 feet, average ambient temp mid 70s. Without the driving I did on the trip, that topped off the battery level, solar, or some other means will need to be used to supplement the battery life. UPDATE: Currently using a Goal Zero Boulder 100 to augment the battery. To properly interface with the solar panel I purchased an 8mm to SAE and a SAE to SB50 Anderson cable as recommended by Dometic customer service. The Boulder 100 kept my PLB40 topped off, charged two phones, and a GPS unit. The product is sleek, lightweight, easy to use and has great informational videos online.

## Questions & Answers

**Q: How long does it take to charge from the 12 volt plug and solar and mains? What is the Amp draw from the charger?**
A: Dometic thanks you for your question.  The PLB40 Recharges in just 5 hours from 0% capacity using DC or AC power and without special charging equipment.  For further information, contact our support team at customersupportcenter@dometic.com.

**Q: If battery is connected to 12v to recharge and i stop the car, is there a way for it to stop recharging so it doesn't suck my car battery dry?**
A: It depends on whether or not the 12V in your car stays live when the engine is off.  In my experience, most don't.  The battery itself doesn't have a cutoff that I am aware of.  I keep it plugged into a receptacle that isn't live when the engine is off and there is no draw that I am aware of.

**Q: can you jump start or trickle charge a dead car battery with this?**
A: Dometic thanks you for your question.  You cannot jump start a car with the PLB40.  For further information, contact our support team at customersupportcenter@dometic.com.

**Q: How long does it take to charge from solar? and what is the greatest amount of solar panel wattage? and can it run of multiple panels (ie,2x 60w=120w)**
A: Dometic thanks you for your questions.  There are a few notes on this to explain;  
1. How long to charge from solar?
             a.	It depends on the panel’s amperage output.  Check your panel specs.  The PLB40’s DC and AC input is regulated at 8A giving it a 5hr charge time from 0-100%.
2.	Largest panel- 180W.
3.	Cannot support multiple panels.

*by M***N on 1 December 2019*

I've only had the PLB40 for a little while but I already love this baby. I wanted a backup battery to run the Dometic CFX50 that I didn't have to worry about maintenance-wise for a decade or longer. I already have multiple inverters, I don't need one built into the battery so I'm fine with it not having an AC output. And I wanted the DC inputs to be flexible and the DC outputs to be regulated, which they are. This little LiFePO4 battery with its flexible input sources and regulated DC outputs is just perfect. I did a little initial discharge test and at house-ambient temps (70F) and the CFX50 set to 40F (std refrigeration temp), soft drinks and starting from an already-cooled steady state, the battery will run the unit for 2 days of normal use and still have 25% capacity left at the end of that. One thing I especially like is that the battery's 12VDC input for charging won't pull more than 100W from a vehicle's 12VDC output and thus not overburden that or other power sources one might plug into it. It's a 'don't have to worry' amount of current. The LiFePO4 chemistry means the I generally don't have to worry about maintenance, safety, or cycle life. The battery itself should last a very long time (usually the electronics built into these batteries fail before the battery chemistry itself does). But, of course, I've only had it for two months... so time will tell. Also the failure mode for this battery chemistry is typically just steadily-degrading capacity. I have high expectations. -- UPDATE FEBRUARY 2021 -- I am happy to report that the battery has been completely maintenance and trouble-free. Its gotten some use from the CA power safety blackouts in 2020 as well as took a few trips running my Dometic cooler. The only thing I would say is different now is that there quite a few other LiFePO4 battery 'generators' (they call them) out there with roughly similar capacities that are a whole lot cheaper. Battery costs have gone down drastically, but these name-brand special-purposes devices are still being sold at a hefty premium. Maybe checkout a Jackery of one sort or another instead... but keep in mind you need to find the right cables when hooking things up. Remember that these battery systems work best with DC-to-DC. DC output from battery system, DC appliance. Anything you run through an inverter will burn energy a whole lot quicker due to the inverter's high idle consumption. -Matt
