FAQS
Q. What should I do if my power bank won't charge?
A.
If your power bank won’t charge, please follow these steps to troubleshoot:
1. Try a different charging cable and charger
Use another USB cable and charger to connect your power bank, and let it charge for 10–15 minutes to see if it starts working.
2. Test other power sources
Plug into a different wall outlet, a computer USB port, or another charging device to rule out power source issues.
3. Check the power bank’s battery level and indicator lights
If the battery is very low, it might not start charging right away. Keep it plugged in for at least 30 minutes before checking again.
4. Press the power button
Some power banks need to be manually turned on to begin charging. Press the power button briefly and see if any indicator lights turn on.
5. Inspect the power bank’s condition
Look for any swelling, deformation, or unusual heat. If you notice any of these signs, stop using the device and replace it.
⚠ If these steps don’t fix the problem, please contact our customer support for further assistance.
Q. How long does it take to fully charge the power bank?
A.
- 10,000mAh Power Bank:
Standard charging takes about 6-8 hours.
Using an 18W or higher fast charger: fully charges in about 4-6 hours.
- 20,000mAh Power Bank:
Standard charging takes about 8-10 hours.
Using an 18W or higher fast charger: fully charges in about 6-8 hours.
For LED fast-charging models, the first indicator light turns green during fast charging.
For models with a power display, a green lightning bolt icon appears while fast charging.
Q. How many times can a 10,000mAh or 20,000mAh power bank charge a phone?
A.
The number of charges you can get depends on your phone’s battery size and the power bank’s efficiency. Here’s a general estimate:
- 10,000mAh Power Bank
If your phone battery is around 3,000mAh, it can charge about 1-2 times.
- 20,000mAh Power Bank
If your phone battery is around 3,000mAh, it can charge about 3-4 times.
⚠ Actual charges may vary based on phone usage and power bank wear.
Q. Why is the battery capacity of a power bank different from its rated capacity?
A.
Battery Capacity (mAh)
- Refers to the internal battery’s total charge, measured in milliampere-hours (mAh).
- Examples: 10,000mAh, 20,000mAh.
Rated Capacity (Wh or mAh)
- This is the actual usable capacity available to charge your devices. Since the internal battery (usually 3.7V) needs to be boosted to 5V for USB output, some energy is lost during this conversion.
- Rated capacity is typically lower than the battery capacity. For example, a 20,000mAh power bank might have a rated capacity of around 12,000mAh (at 5V).
💡 Simply put, battery capacity is the total energy stored inside the power bank, while rated capacity is the actual power you can use to charge your devices.
Q. Can I bring a power bank on a plane?
A.
You can bring power banks on planes as long as they follow airline rules:
- Under 100Wh (like 10,000mAh/38.5Wh or 20,000mAh/74Wh) are allowed without restrictions.
- Between 100Wh and 160Wh require airline approval, and you can carry up to two.
- Over 160Wh are not permitted.
- Check your airline’s specific regulations for details.
⚠ Power banks must be carried in your carry-on bag—they cannot go in checked luggage!
Q. Can I take a power bank with me when traveling abroad?
A.
Please note the following tips for using your power bank abroad:
- Power bank compatibility: Our power banks support the universal USB charging standard (100-240V), so they can be used in most countries.
- Different plug types: Since outlet types vary by country, you may need a plug adapter to charge your device properly.
Q. What does the LED indicator on a power bank mean?
A.
Most power banks have a built-in four LED lights indicator to let you know whether your power bank is full charged. Here is how the LEDs show the remaining power:
4 LED lights indicator : It is charged between 75%-100% and charging.
3 LED lights indicator : It is charged between 50%-75% and charging.
2 LED lights indicator : It is charged between 25%-50% and charging.
1 LED lights indicator: It is charged about 25% or < 25% and charging.
Q. Is it normal for a power bank to get warm?
A.
Power banks generate some heat while charging or discharging, especially at high power levels. It’s normal for them to feel warm during extended use or in hot conditions. However, if it becomes too hot to touch or stays hot for a long time, stop using it and have it checked for any issues.
Q. Why my power bank can't charge to devices next day after fully charging?
A.
Normally, the power bank is fully charged with all four LED lights stay on without blinking. If you just put it on bag or in drawer without using it, then press the wake-up key on the side of power bank for 10 secs accidently, this action might cause the IC component of power bank is blocked which can't discharge, therefore, you need to recharge power bank for 3~5 mins to disable this function and get it back to normal.
Q. Can power bank charge and discharge simultaneously (aka pass through charging)?
A.
Our power bank does not support this pass through charging function because it might
affect the lifespan of power bank's battery.
💡 Please be sure to full charge the power bank first before using in order to extend the lifespan.
