"Kept this in the ute for eight months before I needed it. Battery died in a car park, phone on 12%, two hours from home. Threw the solar bank on the dash while I waited for roadside — got enough charge to make the calls and keep the kids entertained. Bought two more the next week."

Product Description
When the power fails, your phone becomes a countdown. When crisis hits — storms, floods, grid failures, bushfires — communication is your lifeline. Power goes out, towers strain, roads close. And while everyone else watches their battery drain to nothing, unable to call for help or reach their family, what will you do? Unlimited power from the sun. The SOLAR-S1 harnesses solar energy to keep your devices charged when the grid collapses. No outlet needed, no working power lines — just renewable power that keeps you connected anywhere. Real capacity, fast charging. 20,000mAh charges a phone about 4–5 times, with 20W USB-C fast charging, a wireless pad and USB-A — three devices at once. Built to survive. IPX5 water-resistant, shockproof and dustproof, with dual LED torches and a compass carabiner. No shelf life — grab it and go.

Power That Doesn't Rely on the Grid

A rugged 20,000mAh solar power bank that keeps your family connected when the outlets are dead.

Power That Doesn't Rely on the Grid
1

20,000mAh Capacity

Charges a typical phone about 4–5 times, or a tablet twice, on a single top-up.

2

Solar + USB-C Charging

Recharge from the sun outdoors, or fast-charge from a wall outlet — never grid-dependent.

3

3 Devices at Once

Wireless pad + 20W USB-C + USB-A charge a phone, torch and tablet together.

4

Dual LED Torches

Built-in lights for blackouts, night emergencies or signalling.

5

Rugged & Weatherproof

IPX5 water-resistant, shockproof and dustproof, with a compass carabiner.

How It Works

Charge It Three Ways

Top it up from the built-in solar panel in the sun, or fast-charge from a wall outlet via USB-C. You're never dependent on the grid to keep it ready.

Power 3 Devices at Once

A wireless charging pad on top, plus USB-C (20W fast) and USB-A ports — charge a phone, a torch and a tablet at the same time.

Light When You Need It

Dual super-bright LED torches built in for blackouts, night-time emergencies or signalling for help.

Built to Survive

IPX5 water-resistant, shockproof and dustproof, with a compass carabiner to clip it to a pack. No shelf life — grab it and go.

the moment your battery hits zero

WHAT A DEAD PHONE COSTS YOU IN A CRISIS

Emergency Alerts
Weather warnings and evacuation orders come to your phone — until the battery's gone. Why it matters: you miss the warning that tells you when to move.
Calling for Help
A dead phone can't reach emergency services, roadside assistance or your family. Why it matters: no way to say where you are or that you're safe.
Navigation
No maps and no GPS once the battery dies. Why it matters: you're navigating a crisis blind.
Torch & Signal
Most people use their phone as a torch — until it's flat. Why it matters: no light and no way to signal at night.
Staying Informed
No news, no updates, no idea what's happening outside. Why it matters: you're making critical calls on guesswork.

Saved Me in a Car Park

Battery died two hours from home, phone on 12%. Threw the solar bank on the dash and had enough charge for the calls within the hour. Two more on the way.

★★★★★

Ran Our Phones for Days

Storm took our power out for three days. This kept two phones and a torch going the whole time — charged it back up on the windowsill each morning.

Lives in the Glovebox

Compact, tough, and I never have to think about it. Topped up once a month in the sun and it's always ready.

Can it charge more than one device?
Yes — three at once: a wireless charging pad on top, plus USB-C and USB-A ports.
Is it weatherproof?
IPX5 water-resistant against rain and splashes, plus shockproof and dustproof for rough conditions.
How big is it?

Does it have a light?
Yes — dual super-bright LED torches built in for blackouts, night emergencies or signalling.
