The power bank that doesn't quit on the trail.
Most power banks drain in your bag, waste energy and give up in the cold. HikingPower is being built to hold its charge, survive the weather and keep your phone alive out there.
Funding goal: €6,000 for the first prototypes
On the trail, your phone is your map, camera and emergency line.
It drains in your bag
Many power banks slowly lose charge while you carry them, even when you never press a button.
It wastes energy
A typical power bank only delivers 60–75% of its stored energy. The rest is lost as heat.
It struggles in cold and heat
Below 0 °C most power banks refuse to charge, and in hot sun they slow down or stop.
What HikingPower is built to do
These are the targets for the first prototype. Every one of them will be measured and published.
Holds its charge
Loss per month in your bag, thanks to a true off-mode with no standby drain.
Wastes less energy
Of the stored energy comes out of the USB-C port, using efficient electronics and good cells.
Built for cold and heat
An insulating layer protects the cells, and a small heater warms them so charging at the plug still works.
Waterproof
Survives rain and a drop in a stream, down to 1 meter, with sealed USB-C ports and no flaps to lose.
The details
An olive green housing with rubber end caps, a lanyard loop and grip ribs. Made to blend into the forest, not stand out.

€6,000 for the first prototypes
Anything above €6,000 goes toward safety certification, the step needed before HikingPower can be sold.
| Safety check of the electronics by an engineer | €2,000 |
|---|---|
| Circuit boards and parts for 10 prototypes | €800 |
| Battery cells and test equipment | €500 |
| Housings and seals | €500 |
| Test round with 10 hikers | €300 |
| Second, improved prototype round | €1,000 |
| Fees and buffer | €900 |
| Total | €6,000 |
The plan
- BuildPrint and assemble the first prototypes with a 3D printer.
- MeasureTest every claim: standby loss, efficiency, cold, heat and water.
- Trail testReal hikers take it out on multi-day trips and report back.
- ImproveBuild a second, better version based on what we learn.
The images show an impression of the final product and all numbers are design goals. Test results will be shared on the GoFundMe page, good or bad.
Keep your phone alive out there.
Every donation helps, and sharing the campaign with friends who love hiking helps just as much.

Two sizes, one design: olive green, insulated and waterproof. Prices will be announced when the shop opens.
The shop opens after certification
HikingPower is still a prototype. Orders open once it has passed testing and the safety certification every power bank needs before it can be sold in the EU.

Questions
When can I buy a HikingPower?
After the prototypes are tested and the power bank has passed safety certification. The shop opens at that point, and the date will be announced on the GoFundMe page.
Why does it lose so little charge in my bag?
It has a true off-mode that disconnects the electronics from the batteries. Most power banks keep a small circuit running all the time, which slowly drains them.
Does it work in the cold?
An insulating layer slows down cooling, so the cells keep more of their capacity. When it is plugged into a charger, a small heater warms the cells first, so it can still charge below freezing.
Can I charge it with a solar panel?
Yes, any solar panel with a USB-C output works. HikingPower itself is built around the power bank, so a panel is not included.
Is it allowed on a plane?
Yes. Both sizes stay under 100 Wh, the limit for power banks in hand luggage on most airlines.
Are the numbers already measured?
Not yet. All values are design goals for the first prototype. Test results will be shared on the GoFundMe page, good or bad.
