Under $1000 buys you 300Wh to 700Wh. That is the honest starting point, because most "1000Wh for under a grand" claims involve a sale price that has since expired or a unit with a lithium-ion pack that will not last.
What that capacity actually runs: a 40L car fridge overnight, several device charges, camp lights, and a CPAP machine if you choose carefully. It will not run a kettle, a microwave, or an induction hob for more than a few minutes.
Here is how to choose, then the units worth looking at.
Work Out Your Capacity First
Add up what you actually need per day, in watt-hours.
A 40L compressor fridge draws roughly 30 to 45Wh per hour averaged across a day, so 720 to 1080Wh over 24 hours. That alone exceeds anything in this price bracket, which is the single most useful fact in this article.
The way people run a fridge on a 500Wh station is by recharging it daily from a solar blanket or the vehicle's alternator, not by running it from stored capacity alone. Budget for the panel or the DC-DC charger as part of the setup, not as an optional extra.
Phones, cameras and a laptop come to perhaps 150 to 250Wh a day. Camp lights are negligible. A CPAP machine runs 30 to 60Wh per hour, so 240 to 480Wh a night, which a 500Wh unit covers with nothing to spare and a 700Wh unit covers comfortably.
What Else to Check
Battery chemistry. LiFePO4 over standard lithium-ion, without exception. Two to three thousand cycles against five hundred, better heat tolerance, and far more stable. It is heavier and it lasts several times longer. In a hot car in an Australian summer, that stability is not a theoretical benefit.
Output ports. A 12V DC socket for a fridge or compressor, 240V AC for anything mains-powered, and USB-A plus USB-C. Check the continuous AC output in watts, not just the surge rating, and check whether the inverter is pure sine wave. Modified sine wave upsets some medical equipment and some chargers.
Recharge inputs. Solar input with a decent MPPT controller, 12V car charging, and mains. Check the maximum solar input voltage and wattage, because that determines which panel you can pair with it. A station accepting only 100W of solar is a poor match for a 200W blanket.
Weight and build. Anything above about 8kg stops being carried casually. Look for reinforced corners, a stated IP rating, and a handle that will survive being grabbed with one hand out of a loaded ute tray.
Pass-through charging. Being able to charge the station and run loads simultaneously matters more than the spec sheets suggest, particularly when solar is trickling in during the day while the fridge runs.
The Units Worth Looking At
Prices move constantly and the sub-$1000 bracket is where sales matter most, so treat these as models to watch rather than fixed recommendations.
Bluetti EB and AC series
Solid construction and a good record. The EB3A, EB55 and EB70 sit between 268Wh and 716Wh, and the AC70 is worth checking when it is discounted.
LiFePO4 across most of the range, multiple charging inputs, straightforward interface. The EB70 at 716Wh is about the largest genuinely useful capacity in this budget.
EcoFlow River series
The River 2 and River 2 Pro run 256Wh to 768Wh with the fastest AC recharge in the class, often reaching 80% in under an hour.
That recharge speed is more useful than it sounds. It means a station can be topped up during a short stop at a powered site or from a vehicle inverter over a lunch break, which changes how you plan a trip. App control and a wide port selection round it out.
Dometic PLB40
512Wh, built specifically to run Dometic fridges, and tough.
Narrower in scope than the others, with fewer AC options. If your requirement is genuinely "keep the fridge running", it does that job as well as anything and integrates cleanly with the rest of the Dometic ecosystem.
Companion
An Australian camping brand with local support and distribution, which matters for warranty claims in a way that offshore-only brands do not.
The larger Rover units exceed this budget; the smaller stations are worth watching on sale. Built for practical use rather than for specification sheets, with built-in MPPT solar controllers.
Anker and Jackery
Both consistently well reviewed in the 300Wh to 700Wh range, with good safety records and competitive pricing.
Check the specific model's chemistry before buying, because both brands still sell lithium-ion units alongside LiFePO4 ones at similar prices, and the difference in service life is several years.
Buying Advice
Match the capacity to a calculated daily load rather than to a number that sounds generous. Insist on LiFePO4. Budget for the solar panel or DC-DC charger at the same time, because a station without a way to recharge it in the field is a large battery with a two-day life.
And check the continuous AC output against whatever you intend to plug in. A Portable Power Station rated 300W continuous will not run a 900W kettle regardless of how much capacity it holds, and that mismatch is the most common disappointment with units in this price range.
