What Is Power Bank Sharing? The Charging Solution That's Already in Your City
You've probably used bike sharing. Maybe scooter sharing. There's a good chance you've used car sharing. The pattern is the same every time: instead of owning something you only need occasionally, you access it on demand, pay for what you use, and leave it somewhere for the next person.
Power bank sharing works exactly the same way. And if you've spent a day navigating a city on a dying phone, you'll immediately understand why it exists.
What Is Power Bank Sharing?
Power bank sharing is a service that places portable charging stations at venues — cafés, restaurants, bars, hotels, shops — throughout a city. Users rent a power bank from any station, keep it for as long as they need, and return it to any other station in the network when they're done.
You don't have to return it to the same place you picked it up. You don't need to own a charger. You don't need to find a wall socket and sit next to it for 45 minutes while your drink goes cold.
You just pick up a power bank, put it in your pocket, and go about your day.
How Does It Work in Practice?
The process is straightforward:
- Download the app — in the case of Fully, it's available on iOS and Android at fullygo.com
- Find a station — the app shows a live map of every station in the network, so you always know what's nearest
- Rent a power bank — scan the QR code on the station, and a power bank is released. No waiting, no staff needed.
- Use it — the power bank has cables for USB-C, Lightning, and Micro-USB built in. It works with any smartphone.
- Return it — whenever you're done, just slide the power bank back into any station in the network
Rental pricing is typically per-unit of time — Fully charges €1 per 30 minutes.
Why Does This Exist?
The honest answer: because our phones are our lives, and their batteries haven't kept up.
Modern smartphones are used as cameras, maps, payment terminals, translation tools, social media platforms, and music players — all at once. A full charge in the morning is often 20–30% by mid-afternoon, especially on a warm day, with location services running, and a lot of photos being taken.
Meanwhile, the old solution — finding a café with a free socket, ordering something you don't want, and sitting there for an hour — is getting worse as cafés increasingly reserve sockets for paying customers, or don't have them at all.
Power bank sharing fills the gap. It gives you the convenience of a personal charger without the weight, the cable, or the need to plan ahead.
Who Uses It?
Tourists are the most natural users. When you're travelling, your phone usage spikes — navigation, photos, researching restaurants, translating signs, sharing location with your travel companions. And unlike at home, you can't easily pop back to charge. You need power right now, on the go.
Locals use it as an emergency service — you left home in a rush, didn't charge last night, and now you're heading out for the evening with 15% battery. €1 to not be that person who can't split the bill because their phone died.
Event attendees are also heavy users — festivals, flea markets, outdoor events, concerts. Any situation where you're away from a power source for an extended period, with a lot of reasons to use your phone.
What Makes It Different From a Normal Power Bank?
A few important things:
You don't have to carry it home. This is the big one. You pick it up, use it, return it. No charging it overnight. No carrying it around when you don't need it. No leaving it in a different bag and discovering it's not there when you need it.
It's always charged. A station's job is to keep its power banks fully charged and ready to go. You never pick up a dead one.
It's always nearby. The network effect matters here. The more stations exist in a city, the less you have to think about it — you stop at a café you would have stopped at anyway, and there happens to be a station there.
It works with any phone. Built-in cables for USB-C, Lightning, and Micro-USB mean it doesn't matter what you're carrying.
Power Bank Sharing in Barcelona
Fully is the power bank sharing service operating in Barcelona — and now in Palma de Mallorca.
Barcelona is one of the best cities in the world for this kind of service. It's extremely walkable, extremely tourist-heavy, has a long summer season, and the old city (Gothic Quarter, El Born, Gràcia) means long stretches of walking between meaningful stops.
Fully stations are currently live across the city: the Gothic Quarter, Eixample, El Born, Gràcia, Poblenou, Paral·lel, and Raval.
Partners include: Cake-me, PaTapas, Charcha, Galeria Maxó, La Chinata, Gelato Fest BCN, Koi Koi (multiple locations), Kyomi Tea, Himalayan Restaurante, Vespa Soul, By Nata, Flipe Café Market, Gula, Restaurant Teruel, and more.
The network is growing. Every new partner venue is a new point in the grid — which means that eventually, wherever you are in the city, there's a station around the corner.
Download the app, find your nearest station, and never sweat the battery percentage again.

Frequently Asked Questions
Is power bank sharing safe?
Yes. The power banks and cables are maintained by the service operator. They're standard, certified mobile charging hardware — the same technology as the charger you use at home.
What if I keep the power bank for a long time?
You pay for the time you use it but we also cap your 24 hour fee for €8. If you have a power bank for six hours, you pay only €8. Most people return it within 90 minutes. If you lose it, there's a replacement fee — but stations are everywhere, so there's no reason to hold onto it longer than you need it.
Do I need to create an account?
Yes — a quick account setup is required to register a payment method. It takes about two minutes. You can use Google Pay, Apple Pay, Alipay or any Credit Card that you own.
What phones does it work with?
Any smartphone. The cable has USB-C, Lightning (iPhone), and Micro-USB connectors built into the power bank.
Can I use it for more than just phones?
Yes. Any USB-C devices like earbuds and tablets will work as well.
