Why Voltsen

Engineered to handle whatever Australia throws at it.

LFP & LMFP cells

Automotive-grade lithium iron phosphate chemistry. 3,000+ cycles, no thermal runaway risk, safer in your van than lithium-ion.

Solar-ready MPPT

Every Roam and Base unit takes solar input directly. Plug in a Voltsen Sun panel and recharge anywhere with sky above.

Pure sine wave AC

Run sensitive electronics, CPAP machines, laptops and fridges without harmonic noise. The same waveform you get at home.

Fast charge

0–100% in around an hour on the larger Roam units. Top up at a servo, recharge at camp from solar, or trickle from the car.

UPS on select models

Roam 1800 and Base 2400 include uninterrupted-power-supply switchover for blackouts — your fridge keeps running, you keep working.

Built for Aussie heat

Tested for high-ambient operation. Active cooling, IP-rated solar panels and intelligent thermal management for outback summers.

Off-grid, on the road, or back at home.

Pair any Voltsen power station with a foldable Sun panel and you've got a silent, self-contained energy system. No fuel. No fumes. No noise. No extension lead.

Who's behind Voltsen

Backed by Optitec — an established Australian business.

Voltsen isn't a faceless web shop. It's the outdoor power brand of Optitec (ABN 90 671 412 847) — an Australian company with years of experience importing, distributing and supporting technology products. Same team, same warehouse, same phone number that actually gets answered.

We're new as a brand, so we're not going to show you a wall of five-star reviews we don't have yet. Instead, we put it in writing:

  • 3-year warranty, handled in Australia — faults are sorted here, not by shipping your unit overseas.
  • 30-day risk-free trial — use it properly, and if it's not right, return it for a full refund. We cover the return freight.
  • Full Australian Consumer Law rights — our guarantees sit on top of the ACL, never instead of it.
  • Talk to a person — 0417 367 257 or info@voltsen.com.au, answered in Australia.
