Frequently Asked Questions
Usage
How do I know that the powerbank is fully charged?
How long do I need to charge the powerbank for the first time?
The time for a full charge depends on the capacity of the powerbank, the remaining power in the powerbank and the power supply.
Please consult the quick manual for the estimated charging time for the first use.
If your device is actively in use during the charging process, the charging performance may be elongated.
How do I charge my powerbank?
You charge the powerbank via a USB-charger that is connected to a wall power outlet.
The indication LED will start blinking when the battery is charging.
The upper indicator will also flash as long as the battery is charging.
The LED's show the status of the charge as well:
- 1st led - 25%
- 2nd led - 50%
- 3rd led - 75%
- 4th led - 100%
Disconnect the powerbank from the power, the LEDs will be lit constantly for 1 minute.
Afterwards, when nothing is connected, the LEDs will go OFF.
Are powerbanks allowed to be taken on board of a flight?
In general all our powerbanks are suitable for air travel, since they confirm to the general requirements of a capacity of less than 100 Wh (Watt hours) and 2 grams lithium, as long as you keep the powerbank in the carry-on/hand luggage (and not in checked luggage) and declare the powerbank at customs.
However, requirements depend on the airport you are travelling from and the airline you are travelling with. We advise to always check in person with the airline, by either calling or chatting, before travelling for more information.
To determine Wh: (mAh x 3.7V)/1000
For example, a 20.000 mAh powerbank would be (20000 x 3.7)/1000 = 74 Watt-hours.
My powerbank is still charging. How long does it take to charge the powerbank?
It can take at least 5 hours for a full charge, depending on the charger used.
Can the portable battery charge my tablet?
If the portable battery has 5W or 1A output, it can charge smartphones but not tablets (except for iPad mini).
Can the portable battery fully charge my phone?
The bigger the capacity of the battery, the more likely it can charge your smartphone fully, or even multiple times.
How do I charge my device?
How do the buttons work?
How can I tell when power bank is fully charged?
Why does it sometimes take more time to charge the powerbank?
Does the flashlight work during charging?
Is it possible to simultaneously charge my device and charge the battery of the powerbank?
What is the lifespan of the powerbank?
(charge then discharge = 1 cycle, regardless of whether you charge/ discharge it partially or fully).
Solving problems
My powerbank doesn't turn on.
- It is possible that your powerbank is fully drained. Please charge your powerbank. The indicator will start blinking when the powerbank receives sufficient power.
- It is possible that your powerbank went into sleep-mode. The powerbank will automatically cut-off the power and go into sleep-mode when it detects possibility of over-charge/ over-discharge/ short-circuit. This is sometimes due to faulty cable issue. Please activate the "sleeping" powerbank by charging it with a good condition cable.
Why is the powerbank unable to charge my smartphone?
- Check if the capacity of the powerbank is suitable for your phone.
- Some smartphone cables might not be compatible with a powerbank due to different cable chipset design. We recommend using the cable and connector meant for the powerbank.
Why is the powerbank unable to charge my tablet?
While some tablets can accept lower input (1A or 1.5A), the charging is slower and sometimes can only be charged when the tablet is in sleep mode.
- Some tablet's cables might not be compatible with a powerbank due to different cable chipset design.
For Samsung Galaxy Tab in particular, we recommend using the cable and connector meant for the powerbank.
What can I do when the powerbank doesn't seem to work?
If the powerbank can't charge the device, make sure the powerbank is fully recharged.
If the powerbank is charged, the issue will most likely be with the cable.
You can try to use another cable to charge your device.
If it still doesn't work, the issue might be with the powerbank itself.
You should contact the support team via the 'ask a question' section.
Why does my powerbank battery seem to drain very fast?
- Generally, a well maintained powerbank can retain up to 80-90% of its original capacity. Please check the original battery capacity of your device and the capacity of the powerbank.
- The number of times a powerbank can charge your device depends on the capacity of both the powerbank and the device.
- It is best not to attach cables to the powerbank when not in use.
The powerbank feels warm when (dis)charging. Is this normal?
They may get even warmer if you use your device while charging.
