How To Rent

Pre-Authorisation
Hold Explained
Using our card machine instead of the QR code? Here's exactly what happens with your payment.
A temporary hold is placed
When you tap your card, a pre-authorisation is applied as a security measure; it's not a charge. It simply holds funds as a precaution in case the power bank isn't returned.
Return the power bank to release it
Once your power bank is returned correctly, Joos immediately initiates the release of the hold. No action is needed on your end.
Funds clear within 1–7 working days
The hold disappears from your account within 1–7 working days, depending on how quickly your bank processes the release.
Good to know: Joos releases the hold on our end right away. The remaining wait time is entirely down to your bank's internal processing speed, and unfortunately this is outside our control.

How fast does the power bank charge?
Joos power banks charge at a similar speed to a standard wall charger.
Most phones can get a good charge within 1-2 hours, depending on:
- Your phone model
- Battery size
- How heavily you use the phone while charging
How long will it charge my phone?
Each Joos power bank has a 3000 mAh capacity, which can provide a useful boost for smartphones.
- Ideal for 1-2 hours of charging
- May not fully charge larger phones, but will give you enough power to keep going
Can I charge multiple devices?
Yes, you can! But for the best performance, we recommend charging one device at a time to get faster and more efficient charging.
How do I check the battery level?
There are 4 indicator lights on the power bank. Each light represents 25% of the battery. The power bank is touch-sensitive, so just give it a little shake to activate the lights.
What should I do if the power bank isn’t working?
Try the following;
- Remove and reconnect the cable
- Give the power bank a slight shake
- If it still doesn’t work, contact our support team and we will assist you right away
How do I return a Joos power bank?
- Ensure the cables are neatly tucked at the back
- Press the grey/silver return button on the station
- Insert the power bank into the slot with flashing lights.
- Make sure it is fully inserted
Your rental will automatically end once the return is detected.
If it doesn’t, don’t worry. It likely means the return wasn’t completed properly. Please contact our support team to avoid extra charges and we will assist you right away.
Can I return the power bank to a different station?
Yes, you can return the power bank to any Joos station
How do I know my return was successful?
You may receive:
- A receipt of your rental if you rented using the app
- If you rented by tapping your phone/card, you may see a final charge confirming your rental has ended, while the remining deposit is released
If you are unsure, don’t worry, just contact our support team and we will quickly confirm for you.
Why was I charged after returning?
This usually happens if:
- The power bank wasn’t fully inserted
- A step in the return process was missed.
- The return didn’t register
Please contact our support team and we will review and resolve it quickly for you.
What if the station is full?
If there are no available slots:
- Try a nearby station using the app
- If you are unable to return it, contact us immediately to avoid extra charges.
What happens if I don't return the power bank?
If not returned within the maximum rental period (usually within 24 hours), the rental will automatically end, and the maximum charge will be applied.
What if I can’t find a station to return my power bank?
Don’t worry! Open the Joos app to locate the nearest available station. If you are unable to access a station, please contact our support team immediately and we will guide you to avoid extra charges
How much does it cost?
Pricing is shown before you confirm your rental in the app after scanning the QR code. It is also displayed on the station screen for contactless rentals. This way, you will always know exactly what you are paying before you commit.
How is the rental fee calculated?
You are charged based on how long you keep the power bank. Charges increase incrementally. Billing stops once the return is successful
What is a holding deposit?
A holding deposit is temporary authorization, not a charge.
- It confirms your payment method is valid
- After a successful return, the rental fee is deducted
- The remaining amount is released within 1-7 working days, depending on your bank.
Some banks may charge the rental fee separately and release the full deposit; both are completely normal.
If your deposit takes longer than expected, don’t worry! Just reach out and we will check it for you.
Why was I charged more than expected?
Charges depend on how long the power bank was kept. If something doesn’t look right, don’t worry! Contact us and we will review it for you.
What happens if my power bank doesn’t eject?
This may happen due to connection issues or station maintenance. In some cases, the power bank may have already been released without you noticing. Don’t worry! If you are charged, contact us and we will resolve it quickly.
How do I find a Joos station?
The Joos app makes finding stations super easy!
It includes a map that uses your location to show all nearby Joos stations. You can enter your address into the search box. Once you select any of the venues on the map, it displays the number of available slots, their working hours, and their address. You then select “Take me there”, it would launch Google maps/City mappers to navigate you to the station
You can reach out to customer service if you face any challenges with finding a station.
What if there are no power banks available?
Check the app for nearby stations with available power banks or contact us and we will assist you.
