Q1：Why is "Screen Time," "Battery Cycle," "Total Input," and "Total Output" not showing "0" on display?
A1: To ensure the quality of the product, rigorous tests were conducted. The values recorded during the production and testing process were:
(a) "Battery Cycle" should be 0, and "Battery Health" should be 100%
(b) Other information should not be 0.
Q2: Why is there a "0.1W" output shown for the USB A port when nothing is connected?
A2: Please know that there are usually two reasons for this situation:
1. When the trickle charging mode is opened, there will be a 0.1W output for the USB A port. If you press the power button twice, the trickle-charging mode will be activated, so there will be a small green light shown upper left on the power remain and a 0.1W output shown for the USB-A port.
2. When a device is unplugged from the USB A port, the 0.1W will still last for about 2 minutes just in case the device is not fully charged.
Q3: The UVP warning appears when charging a laptop.
A3: Confirm whether the USB C port of the connected device is a PD port; if so, the PD port can support two-way charging, which means it can either accept power or supply power via this port. While the USB C1 port in our power bank is also a two-way charging port. Therefore, when connecting the device to the power bank, both of them may get confused. If the power bank wrongly recognizes the connected device as a power input source, then the warning may appear.
The USB C2 port will not cause such a problem since it is only a power output port. Please give it a try.
Q4: The UVP warning appears when charging a DJI Mini 3 Pro.
A4: Please know that our engineers have done a lot of tests on the DJI Mini 3 Pro. And here are our findings.
1. DJI's Charging Dock states that it supports power input 5V==3A,9V==3A, and 12V==3A, but our power bank cannot support 12V==3A. So the DJI charging dock will negotiate the power input with our power bank at 9V.
2. But when we connect the DJI charging dock to our power bank, we find that the dock only asks for 9V==2A at the first, so our power bank only gives 9V==2A. That's why you will find the real output hovers around 18W. But sometimes the dock doesn't comply with the agreement, he asked for 9V=2A first but then compulsively drew 3A from our device, thus the voltage our device can finally give will be lower than 9V (because the total needs our power bank received at the very first is 9V/2A=18W, if 3A is drawn, then theoretically the final voltage will be 18W/3A=6V). Therefore, the UVP Low voltage warning will appear.
3. We also test the charging dock with some of our 9V/3A chargers (who also do not support 12V), and the testing results are also the same. So it seems that the charging dock's charging ability at 9V=3A has some unknown problems. Regarding this point, maybe you can also try some 9V/3A chargers (that do not support 12V) to see whether you can get the same results as ours, or you can also have a further discussion with DJ later.
4. We find that the charging dock's charging ability at 12V performs well. When it is charged with a 12V charger or power bank, there will be no charging issues. Therefore, our engineer will improve our power bank and add the charging ability at 12V in the near future, which should help to be better compatible with the DJI Mini 3 Pro.
Q5: The power bank drains quickly when charging a device overnight.
A5: Usually, an external battery could supply 60% of power to other devices. Approximately 40% of the battery capacity is lost in circuit heat and voltage conversions. A fully charged PowerCore 24000 can only offer 13000-14000mAh battery capacity to your devices.
When you have charged your device overnight, the power bank will keep outputting power even though your device has already been fully charged and may not need it, so it will drain quickly much more than in normal conditions.
Therefore, it is suggested to disconnect the device from the powerbank when it is fully charged to prevent the powerbank from keeping supplying unnecessary power.
Q6: It cannot output 140W when charging a Macbook pro 16''.
A6: Please first know that our USB C ports can indeed support 140W output, but it may also require the cable and connected device to support 140W. When you want to charge your MacBook Pro 16" at around 140W, it is recommended to connect the powerbank to your laptop's MagSafe port via the USB C to MagSafe cable.
Q7: When the USB C port is connected to the C-Lightning cable with no mobile phone connection, there is 0.1W~0.2W shown on the screen.
A7: Please know that the C-L cable contains Apple's chip to ensure a connected Apple device can be charged directly and promptly with it, which will consume power in working status, so you will see the information of power output: 0.1-0.2W.
When the power bank detects that the C-L cable continues to have a low current for 2 hours, it will sleep to maintain the power of the power bank. At this time, the user can press the button, or re-plug the cable to reactivate the power output.
Q8: When an iPhone is charged to 80% through the power bank, it may stop charging or very slow
A8: If your iPhone stops charging when charging to 80%, it may be caused by the turning on of "Optimized battery charging". Please turn it off to see whether it helps: go to "Settings" - open "Battery" - open "Battery Health" - Turn off "Optimized battery charging" . If the problem is not solved after the operation, please contact Anker support for assistance
Q9: When either one of the USB C ports is occupied, connecting another device to the rest ports may lead to disconnection and connection to the device connected to the previously-occupied USB C port.
A9: It is due to the smart power distribution mechanism of the power bank. Every time the connected devices change, the power bank will disconnect first, resend the PDO to redistribute the power, and then continue to work.
Q10: Why does the power bank discharge so quickly?
A10: Please confirm whether the device drains quickly when it is not used or used.
If it is the former, please provide some information and try the following tips to see if troubleshooting is helpful or not:
- If you left a USB C to lightning cable in the portable battery when you do not use the PowerCore? The USB C to lightning cable will drain power automatically even though there is no phone connected;
- Confirm whether you turn on the "Auto Screen Off"? If not, please turn it on. If the mode is off, the screen and MCU will always be in working status, which will consume a lot of power: around 15% in a day (24 hours). Therefore, it is suggested to turn on the option "Auto Screen Off" if you do not need to view the screen display information for a long time.
- Please charge the PowerCore fully again, do not leave any cables in, and leave it unused for 1-2 days to see if the same issue happens again.
If it is the latter, please know usually, an external battery could supply 60% of power to other devices. Approximately 40% of the battery capacity is lost in circuit heat and voltage conversions. A fully charged PowerCore 240000 can only offer 13000-14000mAh battery capacity to your devices.
Please try the following troubleshooting:
- Please charge the PowerCore fully again, then try a different cable to your device to see if it works better. Do not leave any cables in the portable battery when you do not use the PowerCore.
- Try a different device to see how it works
Q11: All the ports work only when Powwerbank (A1289) is plugged in for recharging. In battery mode, one or none of the ports work.
A11: Please note that this is not normal. All the ports should work in battery mode, but it also depends on what kind of devices you are trying to connect.
Please try the following:
- Using another cable.
- Try another device.
- Try to reset the powerbank by plugging both ends of the cable into the input and output port of the battery at the same time for 3-5 second and then charge and discharge to see if everything works properly or not.
Q12: iPad pro M1 only charges at 18W and the powerbank is not fast charging.
A12: Please note that your iPad pro M1 can only accept 18W fast charging. Mostly it depends on the charging level of the device and how much it is willing to accept right at that moment of charging.
Q13: USB-C1/C2 can charge normally, but USB-A is intermittently charging.
A13: It is an abnormal situation, please try the following:
- Plugging both ends of the cable into the input and output port of the battery at the same time for 3-5 seconds.
- Recharge and discharge the battery again to see if everything works properly.
- Try another cable with the same device and port (if possible)
- Try charging another device with that port to see if the issue persists.
