Companion Portable Power Pack 44Ah

G'day Mark,

You can't I'm sorry - it's an inbuilt safety feature to protect the battery from overuse and permanent damage.
It might be an idea to move the power pack away from your sleeping space if you can.

G'day Steven,

The AGM 44Ah power pack you've asked this question on can only be charged via 12v for maintenance or top-up charging, and shouldn't be relied upon as the primary charge source.

Realistically, for the situation you are talking about, either could do the trick as your 20L fridge shouldn't be drawing too much power at all.  Whatever the battery will draw from your vehicle will essentially just be maintaining it.

The only other consideration is that these batteries don't have a protection system for the charging source. Triple check if your car still provides power when it's off - you can just plug a phone into charge & see what happens.  If that's the case, then be sure to pull out the power pack charging cables every time you stop, will save you running your car battery flat.

You don't need any specific ampunt of Solar, Steven, but the more solar input you have the more sunlight you can utilise to charge the battery for longer. I think 200W is a good amount to maintain enough power to power a fridge, charge a few devices and run some LED lights.

Any solar panel will work, you just need to make sure you connect the solar panel to a solar controller, then plug the solar controller into the battery pack via a 50A Anderson connector. 

G'day Peter,

A fully charged AGM battery will be 12.8V.  There are charge indicators on this unit, but they don't work when being charged by solar.
As you would with any other battery without an inbuilt charge regulator, if you want to know the charge status, just refer to your inline solar controller.

G'day Tim,

Yep, the power pack can charge and discharge at the same time - similar to if you have solar hooked up.
Hope that helps!

G'day Jeff,

Yes, absolutely. The only consideration is whether or not you have a smart alternator or variable voltage alternator (usually post 2013 vehicles).  If this is the case you will need to pick up a DC to DC charger to charge your portable power pack from your vehicle.

G'day Kat,

These portable power stations has an 80% life cycle, meaning it can use 80% of its capacity before requiring a recharge - this leaves you with approx 35Ah of use.

How many actual hours of power that gives you depends on your appliance.  Best way to work that out is to check your fridge specifications for average power consumption.  Dividing the fridge's power consumption by 35 will give you the approximate hours of run time before charging is required.

G'day Aey,

This is a sealed Power Pack with an inbuilt 44Ah battery.
The internal battery cannot be replaced.

If you are looking for a replaceable battery option, take a look at the Hard Korr Battery Box.
