Are portable power stations worth it? For most Australian camping and touring setups, yes — if you are charging a fridge, lights, phones and a laptop rather than running an air conditioner or a big appliance. A power station is silent, burns no fuel and can be recharged from the vehicle or a solar panel. A generator runs on petrol or diesel and carries exhaust risk; a dual battery is the simplest way to keep a fridge cold while you drive.
What a portable power station is actually good for
A power station stores energy in a battery and gives you standard 240 V outlets plus USB ports, without an engine. That single fact drives most of the practical advantages on a trip: you can run it inside a caravan, camper trailer or tent area without an exhaust plume, and you can top it up from a vehicle socket, mains power at a caravan park or a folding solar panel.
It also keeps your vehicle wiring untouched. A dual battery setup needs a charger, cabling and a mounting spot under the bonnet or in the tub; a power station is a box you carry in and plug in. For a weekend setup built around one fridge and a few devices, that simplicity is the whole argument.
Where it falls short is heavy, sustained loads. Anything that heats — kettles, induction cookers, hair dryers — drains stored energy quickly, and a small unit will trip out on output before it runs flat. Adding a second battery or a bigger unit costs more, so size honestly before you buy.
Where a generator still has the edge — and the rules that come with it
A fuel generator earns its place when you need a lot of power for a long time and can refuel: tools, a big caravan air conditioner, or a group camp where everyone wants 240 V. Run time is limited by fuel on hand rather than a battery’s state of charge.
The trade-off is safety. Queensland Health advises that generators running on petrol or diesel emit carbon monoxide and should only be used outdoors with good ventilation, away from windows and vents. [1] Carbon monoxide cannot be seen or smelled, and accumulation in a home, garage, or caravan can lead to sudden illness, unconsciousness, and death. [1] The guidance also states that generators should never be used indoors—including in a home, basement, garage, caravan, or tent—or outside close to an open window. [1]
Additional safety points: keep the generator dry and avoid using it in rain, turn it off before refueling, and never connect it to a wall outlet to power house wiring, as this can backfeed into power lines. [1] Installing battery-operated carbon monoxide alarms is recommended as a backstop. [1] A permanently installed generator should only be connected by a licensed electrician. [1]
If you camp in a swag, a rooftop tent or a caravan annexe, that outdoor-only rule is the strongest argument for choosing a battery-based system instead.
When a dual battery is the better spend
A dual battery system adds an auxiliary battery charged from the vehicle’s alternator, usually through a DC-DC charger, and often feeds a fixed fridge outlet and some 12 V sockets in the back. Its strength is that it charges while you drive, so a long touring day replaces the energy a fridge used overnight.
It suits readers who mostly move daily, want a permanent install, and run 12 V gear only. It is less flexible if you need 240 V for a laptop or camera charger — that needs an inverter, adding another component and more wiring to get right. It also ties your power to one vehicle, so it is no help around camp or in a second car.
Many tourers end up with both: a dual battery for the fridge in the vehicle and a power station for camp lighting, devices and a backup charge source. That combination covers the common failure far from help — a flat fridge battery with no sun for a day.
What the capacity and output numbers mean
Two figures decide what a unit can do. Watt-hours (Wh) is stored energy — how much you can use before it is flat. Watts (W) is the maximum draw it will supply at once, which sets whether a kettle, a charger or a fridge will start at all.
EcoFlow’s Australian range shows the spread clearly: the RIVER 3 lists 245Wh capacity and 300W output, the RIVER 2 Pro 768Wh and 800W, the DELTA 3 1024Wh and 1800W, the DELTA 3 (1500) 1536Wh and 1800W, the DELTA 2 Max 2048Wh and 2400W, and the DELTA Pro 3 4–12kWh with 4000W output. [2][3] The DELTA Pro Ultra is listed at 6–30kWh with 6900W output and 5,600W solar input. [2][3]
Solar recharging is the other number to check. EcoFlow’s solar generator bundles pair panels with the unit and list expected recharge times — for example, the DELTA 3 Max Plus solar generator with a 400W panel is listed at 6–10 hours of solar recharge. [2] Treat those figures as the best case and plan for less in winter or cloud.
Portable power options compared
| Brand | What they offer | Worth knowing |
|---|---|---|
| Kings | A portable power range on its Australian site, showing 28 products including bundle-and-save options [4] | Individual listings display customer ratings [4]; confirm specifications, warranty terms and shipping for your location on the site |
| Companion | The Rover Lithium 70Ah power station is the model listed on its site [5] | Shipping to Australia is not confirmed, so check availability and full specifications with the brand |
| EcoFlow | RIVER and DELTA ranges from 245Wh/300W up to 6–30kWh/6900W, plus solar generator bundles with listed recharge times [2][3] | Sold in Australia; EcoFlow describes itself as the global No.1 portable power station in sales [2], and a 2025 recall covered 25,000 DELTA Max 2000 units over fire risk [6] |
EcoFlow was founded in May 2017 by Bruce Wang and launched the DELTA Pro in 2021, and its products have taken Australian Good Design Awards, a Red Dot Design Award for the DELTA 2 series and an iF Design Award for its Power Kits. [6] The 2025 recall of DELTA Max 2000 units is worth checking against any second-hand or older unit you are offered. [6]
Which option fits whom
- Weekend camper with a fridge and phones: a mid-size power station sized to your fridge’s overnight draw, recharged while driving and topped up with a folding panel. Silent, no fuel, works inside an annexe.
- Long, hot stays in one spot with heavy loads: a fuel generator, run outdoors well away from windows and vents, with a carbon monoxide alarm in the living space and fuel stored safely. [1]
- Daily-driving tourer running 12 V only: a dual battery charged from the alternator, with a power station as backup for device charging and camp lights.
- Family with a caravan plus a second vehicle: both — a dual battery for the vehicle fridge and a power station that moves between the van, the 4WD and camp.
- Buying on brand history and support: EcoFlow publishes a return and refund policy on its Australian site [7] and states it is available in Australia [2]; for Kings and Companion, confirm regional availability and warranty directly, since shipping to Australia is not confirmed either way. [4][5]
A power station is not the only way to keep a fridge cold or a phone charged, but it is the quietest and the most portable. Confirm current models, capacities and shipping for your location on each brand’s site before ordering.
