G'day Nathan,

The Rover has approximately 56Ah of runtime before needing charge input - this equates to a rough 80% cycle.
Check the specifications on your particular fridge for the rough power consumption, which usually comes in Ah.
If you divide 56 by the power consumption of your fridge, you'll get an idea of runtime.

Hope that helps.

G'day Eric,

This unit does not have jump-start capabilities.
You may need to look at purchasing a separate jump starter unit, or as an alternative look at something like the Hard Korr Battery box.
This does have a jump start terminal, and has the option for you to choose whatever capacity/chemistry battery is required to meet your needs.

G'day Barry,

A cycle is generally considered as a full discharge, which in this case is 100% down to 20%.
If you keep your battery above 75% it will generally prolong the life of the unit when compared to heavy discharging.

G'day Barry,

It depends on what brand of fridge you have, but it's unlikely.  The posifit terminal is not a standard connection available to some fridge brands.
Your best bet would be to grab a standard 12v cig double adapter, which will allow you to run 2 12v cig devices from the Rover.  Just bare in mind the overall combined load from both appliances dont exceed the 10A output capacity.

G'day Barry,

Given we're in the dead of winter, I'd say that's a pretty good outcome & certainly nothing to complain about.
The panels have a maximum output of around 11A, so in ideal conditions, you'll get an output towards that top end of things.

G'day Barry,

All feedback from customers and staff members who own these panels suggests the legs are more than capable of supporting the panels, and shouldn't be of concern.
You are welcome to replace them or find an alternative if you prefer, but it will likely need to be a DIY solution as there's nothing we're aware of as an 'off the shelf' option.

G'day Barry,

If you are not hanging around camp and have the ability to adjust your panels during the day to maximise your output, I'd keep them north facing at a 30-40 degree angle.
We currently have fixed panels on our vehicle, but prior to that would often move our portable panels over the course of the day.  That's not uncommon for people to do this, especially if you have areas of dappled shade that moves.  Starting off more east facing in the morning, and moving over to north as the sun gets higher.
Ive camped in some spot where they've had to be moved every hour or two because the shade was changing so much!
Getting new panels is pretty exciting, so feel free to have a play around with them and move them, change the angle, etc as much as you like until you get used to them & see how the output is affected. 

G'day Barry,

These's no real way to answer this question with any specificity I'm sorry, as it ultimately depends on the panel's age and cell technology, and there are alot of variables to the conditions. Hard Korr may have some more specific data with their tech team, you can reach out to them here, the only other option is to do some testing with an irradiance meter.

G'day Matilda,

No, these units are not designed to be used with inverters as they dont have the discharge capacity to deliver the amount of power usually required to power 240v appliances.
Generally, best practice is to not require 240v appliances when you are camping, and just use 12v options.  If this is unavoidable I would be looking at higher capacity deep cycle battery option to go in a battery box, or purchase a portable power station that has a 240v outlet built in, and has the output requirements for your appliance.

G'day Zac,

The indicator is advising you that the Rover is at 50% capacity.
The battery capacity is 70Ah (so you have used 35Ah) meaning you only have 30% of useable power left.
When the capacity is inching toward 20-25% you'll need to get power back into it.

G'day Geoff,

The Rover 70Ah battery has an 80% lifecycle which equates to 56Ah of use.
56Ah divided by 3Ah draw of the fridge equals just over 18 hours.

Hope that helps!

Thanks for the feedback, Michael!

G'day Mick,

200W is a great size for the Rover 70Ah, and the Crocskin panels have the right output specs for it. As the Rover has a built-in MPPT charge controller, you'll just need to bypass the one provided with the Crocskin panels when charging.

G'day Armand,

The Rover has the following input specs from 12V - 14V 9A, and Solar - 13-30V 12A, so just from that we can see the capacity for input current is much greater for solar.
Most of the panels around would be in the 18-20v mark, which would put you in the ballpark for 250W panels.  If you found some at that 30v end you could get up to 360W panels.
The bigger your panel is, the greater your potential for charging is over 12v.
The other thing to consider is that 12v charging through your vehicle can cost you up to 15% fuel efficiency, so factoring all these things in, I'd be prioritising Solar.
Hope that helps somewhat.

G'day Craig,

Those figures are correct, and its down to the different battery chemistries used in the two Rovers.
The Rover 40Ah is LFP, whereas the Rover 70Ah in NMC.
The NMC chemistry has a much higher energy density, a higher nominal voltage, and has up to double the discharge current rate of LFP.  It's a bit of give and take with battery chemistries, so the trade-off of this is that you end up with less lifecycles.

G'day Jeffery,

The Solar Input requirements for the Rover 70Ah are 13-30V 12A (Max).
Different make and model panels will have different outputs. Two different 300W panels may have different V & A ratings.
You'll need to check the output on the sticker on the back of your panel for compatibility.

G'day Simon,

The Solar input requirements on the Rover Lithium 70Ah Power Station is 13-30V / 12A (360W) max.
As long as the output specs of the solar blanket fit into these requirements, you'll be fine.  I'd recommend looking at the largest size you can to maximise charging efficiency.  Something like the Hard Korr 200W Portable Solar Panels with Crocskin Cell Armour or the Companion 200W Solar Charger would be a good place to start.

G'day Michael,

There is no need to worry here, it is very common for 240V transformers to heat up while charging. Most laptop chargers and other device chargers will get just as hot, which is completely normal.

G'day Tony,

Companion state -10° to 40°C as the ideal temperature range on the Rover Lithium 70Ah Power station, but they haven't provided any information on thermal protection.  I've touched base with them to see if I can get anything further on this for you.

G'day Darryl,

This is a common question, and as far as my research has taken me, the answer is no.  At this stage I'm yet to come across an adapter for this port, however, the best workaround is to purchase a good quality double adapter to plug into the 12v cigarette outlet, which will allow you to run two standard 12v cigarette appliances/devices.

G'day James,

Yes, you can charge the Rover Lithium 70Ah from your cars 12V socket while driving. The review from Graham has been negated in his following review. He had a faulty charger, that Companion has since replaced for him.

G'day Lachy,

Being a Lithium battery the Companion Rover Lithium 70Ah Power Station will be fine if left on its side.
As long as you have easy access to the control panel you shouldn't run into any trouble.

G'day Maddie,

No, the Companion Rover Lithium 70Ah Power Station cannot charge a laptop as it does not have 240v output.
It may be possible if you add an inverter into the equation, but that's not a straightforward answer as it depends on your individual laptop's power requirements, etc.

G'day Kylie,

Thanks for the tip, you're correct, if you've got a USB-C charging option, then yes, you can charge up a laptop.

G'day Kat,

You can use any kind of solar panel with the Companion Lithium Rover 70Ah Power Station, they do not have to be the same brand, but they do need to meet the Amp and Wattage requirements.  Ultimately you'll be using a 'raw' panel and plug that straight in, or if you have existing panels with the solar regular attached, you'll need to bypass those.
Basically, you'll be looking at panels within around 160-360W, the higher the wattage, the shorter your change time will be.
Hope that helps!

G'day Lauren,

Unfortunately, this combination won't work. The Rover unit has a built-in MPPT solar controller, so you'd need to bypass the PWM modulator on your solar panels if you wanted to use them to charge the unit.

G'day Steve,

As far as we know there aren't two-pin to 12V Cig socket adapters on the market, but Engel does make their 2-pin posi-fit plugs separately (we don't currently range them) so they can be wired into a custom lead, so you could possibly use of these to make an adapter. You could use a double adapter on the 12V Cigarette output, it is limited to 10A though, so you'd need to consider what you plug into it.

G'day Dan,

Yes, the 12V 2-pin plug is the same as the Engel Posi-Fit Plug. 

G'day Luke,

The inbuilt MPPT unit is only designed to be used with solar panels. The 12V lead will input 9A per hour, so it will charge relatively quickly.

G'day Dicky,

There isn't a hard and fast rule here, but generally speaking, a Lithium Battery can be run down to about 20% of its capacity before it will stop working, so your theoretical maximum output is 56Ah, divide that by your draw (generally 1-2AH for most Engel / Dometic 40L models in fridge mode), and you should get around 25- 50 hours of run time from the Rover Lithium 70AH. The total usage time will vary depending on the temperature conditions, the fridge, which mode it is running on, and a few other factors. We'd recommend ensuring you've got a way to keep the Power Station constantly topped up, usually a solar panel is a good option.

G'day Ruben,

The Rover Lithium 70AH is covered by a 2 year warranty period, which will cover any manufacturing-related faults with the unit. They should be fully charged at least once every six months, and best practice is to charge the unit before storing. The one year shelf life refers to how long the battery can sit unused while retaining a high level of charge. Lithium batteries will hold onto their charge for a long period of time unlike Lead Acid.
