iTechworld are Australia's 4WD-camping favourite, and a fair benchmark — they're a local brand who back their gear. Voltsen takes them on head-to-head and wins on the things that decide it: newer LMFP cells that hold charge in the cold (vs their LFP), an extra year of warranty (3 vs 2), more solar input, and — across most of the range — a lower price. Same Australian-brand promise — better unit, less money. Scroll down for the model-by-model match-ups (and how we stack up against EcoFlow, Jackery, Bluetti and the value brands too).
Headline watts make big numbers, but they're rarely what you live with. These three are what matter day to day — and they're exactly where Voltsen pulls ahead. In every table below, the green cells mark where Voltsen comes out in front, and the orange column is always Voltsen.
What you actually pay for each watt-hour of storage. Voltsen is competitive or lower in every class — and several hundred dollars cheaper at the mid-size (Roam 1800) tier.
Voltsen is repaired here in Australia — no shipping your unit overseas for weeks like the big imports. iTechworld is local too, but only 2 years of cover to Voltsen's 3.
Voltsen's LMFP cells keep about 70% of capacity at -20°C; the LFP cells in every rival hold around 50%. The difference shows on an alpine or desert morning.

iTechworld are the Aussie 4WD favourite and they market hard — but you're paying for that marketing. Same 2,048Wh battery, same 2,400W output, and the Base 2400 matches their sale price (their RRP is $2,999) while beating them on chemistry, solar, warranty and expandability.
| Voltsen Base 2400 | iTechworld PS2000 | |
|---|---|---|
| AU price (current street) | $1,899 | $1,899 (RRP $2,999) |
| Price per usable Wh | $0.93 | $0.93 |
| Cell chemistry | LMFP — holds charge in the cold | LFP |
| Solar input (off-grid recharge) | 1,200W MPPT | 500W MPPT |
| Expandable | ✓ +B2000 (to 6,080Wh) | — |
| UPS switchover | ✓ <20ms | ✓ |
| Warranty & repairs | 3 yrs — repaired in Australia | 2 yrs |
| Capacity | 2,048Wh | 2,048Wh |
| AC output | 2,400W | 2,400W |
| Australian support | Local — Oakleigh VIC | Local — Perth WA |
| App / Bluetooth | Coming Q3 | ✓ iTechworld app |
iTechworld discount the PS2000 hard, so on price it's line-ball with the Base 2400. The difference is what you get for the money: cold-tolerant LMFP cells instead of LFP, 2.4× the solar input for faster off-grid recharge, a third year of warranty, and expansion to 6,080Wh — which the PS2000 can't do at all. The one thing they have today that we don't: a finished app (ours lands Q3).
The mid-size tier for caravans, jobsites and home backup. The Roam 1800 undercuts the PS1300 by $400 and pushes 500W more AC output — iTechworld's only real edge here is a bigger battery.
| Voltsen Roam 1800 | iTechworld PS1300 | |
|---|---|---|
| AU price (RRP, inc GST) | $899 | $1,299 |
| AC output (continuous) | 1,800W | 1,300W |
| Cell chemistry | LMFP — holds charge in the cold | LFP |
| AC outlets | 3 | 2 |
| UPS switchover | ✓ <20ms | — |
| Warranty & repairs | 3 yrs — repaired in Australia | 2 yrs |
| Capacity | 945Wh | 1,248Wh |
Honest note: the PS1300 carries a bigger 1,248Wh battery and a fast ~2.5-hour wall recharge. If raw capacity is your priority over output and price, it's worth a look — but for most buyers the Roam 1800's extra 500W of output, cold-tolerant cells and $400 saving win out.
1,800W runs a kettle, hair dryer and fridge where the PS1300 taps out at 1,300W — with cold-tolerant LMFP chemistry and a third year of local warranty.
The weekend-camping tier — and iTechworld's closest current unit, the PS800, is a genuinely good one. Here's the honest match-up.
| Voltsen Roam 700 | iTechworld PS800 | |
|---|---|---|
| AU price (RRP, inc GST) | $599 | $659 |
| Cell chemistry | LMFP — holds charge in the cold | LFP |
| Wireless charging pad | ✓ | — |
| Warranty & repairs | 3 yrs — repaired in Australia | 2 yrs |
| AC output | 700W | 800W |
| Capacity | 472Wh | 512Wh |
Straight up: the PS800 is a strong little unit — a touch more output and capacity, and a fast 1.5-hour wall charge. The Roam 700 answers with cold-tolerant LMFP cells, a wireless charging pad, a longer local warranty and a lower price. For most weekend campers it's the smarter buy; if the fastest possible recharge is your one priority, the PS800 is worth a look.
The online value brands win on one thing: a big battery for the money. But they run standard LFP (or older) cells, carry 1–2 year warranties, and the cheapest tiers skimp on a true pure sine wave inverter. Voltsen is the quality step up in the same price bracket — LMFP chemistry that performs in the cold, genuine pure sine wave on every unit, a real 3-year warranty repaired in Australia, and free shipping including remote postcodes. If you only want the cheapest watt-hours, buy budget. If you want the unit to still be there in five years, buy Voltsen.
The premium imports are excellent gear — and priced for it, supported through overseas ticket queues, and shipped back overseas if they fail. Voltsen runs the same tier-1 lithium cells (in our case the newer LMFP chemistry), matches them on the specs that matter, and costs 15–25% less with a real Australian warranty handled here. You're not buying a cheaper product — you're skipping the imported-brand marketing tax.
The Australian portable power market is dominated by global brands that treat us as a secondary territory: stock comes via Asia, support is by online ticket, and you ship the unit back overseas if it fails. Voltsen is the opposite play — same supplier-quality cells, same engineering, but operating costs match the size of our market, with local human support and freight included.
That's why Voltsen is consistently 15–25% lower on price even before considering Afterpay/Zip splitting and our 30-day satisfaction guarantee.
