Best Portable Power Station for a Caravan in 2026 — Sizing Chart Inside

Touring without a powered site is the new norm. Free-camping spots have exploded in popularity, caravan parks are full, and the cheapest available power source for the things you actually use in a van is now a portable lithium power station.

But which one? Here's how to size yours.

The four common caravan power-load profiles

Most touring caravans run some combination of these loads:

• The 12V fridge — averages 25-45W draw when running, cycles roughly 50% of the time. Daily consumption: ~300-450Wh.
• LED lighting — 5-20W draw for 4-6 hours an evening. Daily consumption: ~30-100Wh.
• Device charging — phones, tablets, laptops, drones. Daily consumption: ~30-150Wh.
• The 230V appliance hour — kettle, induction cooktop, hairdryer, microwave. Bursty 1,000-2,000W loads for 5-15 minutes. Daily consumption: ~100-400Wh.

The caravan sizing chart

Numbers assume reasonable solar top-ups during daylight. Adjust up if you're in a shaded site or have heavy 230V use.

Three things to look for specifically for caravan use

1. UPS-grade switchover

UPS (uninterruptible power supply) switchover means the power station seamlessly takes over if your shore-power drops. Important if you run a CPAP — a half-second outage will reset most machines. The Roam 1800 and Base 2400 both have under-20ms switchover.

2. Cold charging

If you tour alpine or southern Tasmania in winter, you'll need a unit that charges below 0°C. Most LFP cells refuse. The Roam 1800 charges down to -10°C — useful.

3. Solar pairing

For multi-day touring, the panel matters more than the unit. Match the panel's wattage to the unit's max solar input (Roam 1800 = 350W max, Base 2400 = 1,200W max). Pair with a Sun 200 for caravan day-touring; double up on Sun 200s for off-grid base camp (a 400W panel is coming in our next production run).

What about the imports?

EcoFlow Delta 2 ($1,299), Jackery Explorer 1000 v2 ($999), BLUETTI AC180 ($1,099 discontinued), and Anker SOLIX C1000 ($999) all play in the same 1,000Wh-class as our Roam 1800 ($899). Side-by-side specs are in our comparison table. Short version: Voltsen is $100-400 cheaper at parity, with the same modern LFP/LMFP chemistry and a real local warranty.

Bottom line

For most Australian caravan tourers in 2026, the right unit is the Roam 1800, optionally paired with a Sun 200 panel (or two in parallel) for genuinely off-grid touring. If you're a full-timer with no powered-site access, step up to the Base 2400.
