Exceeded my thoughts

Well I've only used it once so far, but it powered my opposite lock 72 litre dualzone fridge-freezer which runs the 66 watt snow master compressor plus led camp lighting for 26 hours and it was sitting at 11.5 volts I could have run it lower but I really don't like cycling deep cycles right down all the time. To say I was pleasantly surprised at its performance is a understatement and it's much lighter than my arkpak especially when you have to carry it to a camp site away from the 4wd. I can plug in my 250 watt solar panels during the day and have no need for my generator win all around. Very happy with my purchase.

Excellent product

I already have a great 130ah system in my caravan with a ARK Power Pak and 80000 wat inverter, but its so heavy and far from portable.

I bought the Roman to use for family picnics and fishing trips etc that I needed something a little more portable. I couldnt be happier with the power pack and the service from Snowys.

I do look forward to giving the Roman 44AH power pack a real good test in the near future and I do look forward to doing more business with Snowys.

Thank you again,

Power on the go

great little power source, only been out a few times with it but never failed. Solar panel keeps it powered up for my fridge and lighting around the campsite. USB port is a nice touch with no need to carry an additional connection just for phone. Price is perfect.

Excellent power source when off the grid!

This product and I got off to a rocky arrived undamaged but when I plugged it in the "Fully Charged" light never came on after 30+ hours of charging. Snowys and the manufacturer provided great support and a new one was on its way to me. Tip: keep the original packaging until you know it works properly as it is heavy and difficult to find packaging to return it!

The replacement item has worked perfectly from the time I received it. I’ve used it camping for 1 week, charging it via 240V, 12V cigarette lighter and Roman/Primus 120W solar mat and using it to power a Waeco CFX-28 fridge/freezer and occasionally an iPhone. Through this use I have come to really like the product and these features I really appreciate the most:
• Lights which show the charge status, ie. Low battery warning, charging, fully charged.
• Buttons which turn on and off the power output sockets, with lights which illuminate when turned on.
• The input power from 12V cigarette socket is via an Anderson plug connector, this keeps the cord firmly in place, which can often be a challenging in a car full of equipment. This is a big point of difference to some power packs which use clamps (positive and negatives).
• The USB socket is very handy, especially since everyone has a mobile phone these days and more and more items such as lanterns, torches etc become rechargeable via USB.

I had the Waeco fridge permanently plugged into the power pack and the power pack then got its charge from one of the charging sources above. Great way of doing it as the power pack continually charges and when in the car I didn’t have to worry about the power pack draining the car battery while the car engine was switched off.

Snowys advised to charge it on arrival, then fully discharge. Easy process. Note that when charging, if the power level is below the thresholds noise will continue to emit even while charging and if all the lights black out don't feel just press the RESET button and it comes back to life!

To give a rough idea of my experience with a Waeco CFX-28lt fridge/esky while on a road trip, the Roman power pack provides power for 1.5-2 days.

How long does it power for?1 answer

Need to how many hours the battery runs before it needs recharging

- Alice Springs(3 months ago)

G'day Marie,

Thanks for the great question about the Roman Portable Power Pack 44Ah. It really depends on what you're powering and how many amps per hour it will draw. For example, if you're looking to run a portable fridge you should be able to find the power consumption for the unit on our site and work out how long it will last. It does get a little technical though so you could give us a buzz on 1300 914 007 and we can help you out.

Can you replace the batteries? 1 answer

Can you replace the batteries overtime when needed or is it a sealed unit?

- Charters Towers(3 months ago)

G'day Chris,

The Roman Portable Power Pack is a sealed unit, which makes changing the battery over a pretty hard process. I'm sure that you could probably change it over with a bit of effort but if you're looking for one that you can change the battery on, I would suggest looking at the Engel Smart Battery Box

Anderson Socket1 answer

So does the Anderson socket have it's own circuit breaker? The 12v DC and merit sockets on the front have their own. Which breaker would trip if Anderson socket was overloaded?

- Camden Park(4 months ago)

G'day Adam,

I've given Roman a buzz to confirm for you and they told me that the Roman Portable Power Pack 44Ah has a built-in fuse for the Anderson Socket that is solely for that socket.

Anderson socket maximum current draw. Does this socket have a current draw maximum limit?1 answer

I'd like to run a 350watt dometic pure sine wave inverter through the Anderson socket. It would draw 30amps maximum. Does this socket have a current draw maximum limit?

- Camden Park(4 months ago)

G'day Adam,

The maximum power draw for The Roman Portable Power Pack 44Ah on any single DC socket is 15 Amps, anything higher than this will trigger the circuit breaker and turn the unit off.

Anderson charging?1 answer

When using a solar panel to charge through the Anderson plug, should the display indicate a voltage/current as it does when plugged into 240V?

- Broome(4 months ago)

I had to look into this for you Wade, and going by the instruction manual it looks as though the charge indicators and the display will not illuminate when the power pack is being charged by solar panel. There's a bit of information on this on page 7 of the user manual. If you don't have it on hand, you can download it here.

240v output?1 answer

Can you plug in a 240v appliance and use it to power that? That is something that goes into a normal house electricity socket. Cheers

- Scotts Head(5 months ago)

The Roman Power Pack doesn't have a 240V output sorry Georgia. Goal Zero makes a power pack called the Yeti which does though, you can see them here. These will work for low power devices such as laptops, phone chargers and small electronics that have a power transformer integrated into the cable.

auto cut off for charging1 answer

does the unit automatically stop charging when fully charged by either 12v or 240v,&can it be charged via a cigarette lighter socket in transit

- pearcedale(6 months ago)

G'day Phil,

I've just sussed out the owners manual of the Roman Portable Power Pack 44Ah for you. You can charge it using your cigarette lighter and it will switch over when it's fully charged as well.

Providing power whilst recharging1 answer

Is it ok to have the 35L Waeco fridge permanently plugged into the power pack and simultaneously have the power pack charging from the solar panel? Also, will this reduce the battery performance and life over time?

- Hobart(6 months ago)

G'day Jo,

You'll have no worries at all using your Roman Portable Power Pack 44Ah constantly on your fridge, whilst also attached to the solar panel. It won't reduce the effectiveness of your power pack over time either.

Charging device whilst travelling1 answer

Hi - I'm thinking about this option but have a question. The Andersen plug can take input power as well as output (this is where the solar panel plugs in according to the manual i downloaded). Can I plug in my Andersen plug that I run direct off my main car battery to have the alternator charge it like a second car battery (not for starting, just charging on the run)?

- Perth(7 months ago)

G'day David,

I've had a bit of a chat with our portable power expert, Kev. He said that you can charge your Roman Portable Power Pack 44Ah on the run. In fact, I'll just copy and paste what he said so that there's no confusion! - If you can charge via the Anderson plug with a solar panel, then you can do the same from the car. However, if you leave the battery attached when the engine is not running, it may partly drain the car battery, unless there is some sort of relay that isolates the two batteries. - I hope this clears it all up for you. 

- Snowys(7 months ago)

Hi can this be charged by a 120 w solar1 answer

I read somewhere that you should not use more than 80w solar panel as the amps can go over 6 amps. Is this correct And what is the max amps for solar charge this unit will except. Thanks

- Manor lakes (7 months ago)

G'day Ashley,

I've just had a quick chat with our resident solar expert, Kev. He said that as long as your solar panel has a regulator and that it's giving a regulated supply then you'll be all sweet. The regulator will cut down the output of the panel as the battery fills but it will fill faster than a smaller panel.
