2. For Xiaomi phones, to ensure a secure connection for charging and attachment, use a magnetic case purchased through official authorized channels.
3. The Xiaomi UltraThin Magnetic Power Bank 5000 15W is compatible with iPhone 12 and later models that support MagSafe. To ensure a secure connection for charging and attachment, do not use any case, or use a magnetic case.
4. For other brands or models of phones that support Qi wireless charging, use a magnetic case to make sure the phone can be magnetically attached to the power bank properly.
Q2: How to enable wireless charging on the Xiaomi UltraThin Magnetic Power Bank 5000 15W?
A: Attach the front of the Xiaomi UltraThin Magnetic Power Bank 5000 15W to the wireless charging area on the back of the phone. It will automatically align and start charging, no button operation is required. To stop charging, remove the power bank.
Q3: Will the magnetic force of the Xiaomi UltraThin Magnetic Power Bank 5000 15W weaken or disappear after prolonged use?
A. Under normal usage conditions, demagnetization will not occur. Do not expose the Xiaomi UltraThin Magnetic Power Bank 5000 15W to environments above 80 °C for extended periods.
Q4: Can the Xiaomi UltraThin Magnetic Power Bank 5000 15W charge wirelessly while being charged itself?
A: Yes, you can charge the Xiaomi UltraThin Magnetic Power Bank 5000 15W while simultaneously wirelessly charging another device.
Q5: Will the Xiaomi UltraThin Magnetic Power Bank 5000 15W protrude when charging the iPhone 12 mini/13 mini?
A: When attached to the iPhone 12 mini/13 mini, the Xiaomi UltraThin Magnetic Power Bank 5000 15W can extend beyond the edges of the phone, but this does not affect normal charging or usage.
Q6: Is it normal for my phone to overheat when charging with the Xiaomi UltraThin Magnetic Power Bank 5000 15W?
A: It is normal for the phone to generate some heat when charging with the Xiaomi UltraThin Magnetic Power Bank 5000 15W.
Please refer to the following points:
1. If the phone becomes excessively hot, check for any metal objects on the back of the phone. Metal objects can reduce the power bank’s conversion efficiency, leading to increased heat generation.
2. Check whether the phone is in a protective case. Phones in cases tend to become warmer than those without cases during wireless charging.
3. Consider the ambient temperature. If the room or environment is hot, the phone may heat up more noticeably while charging wirelessly.
Q7: Why does the Xiaomi UltraThin Magnetic Power Bank 5000 15W sometimes disconnect when charging a phone?
A: Most Android phones on the market currently do not support magnetic attachment, meaning they do not have built-in magnets on the back to align with the power bank’s magnetic ring.
If the alignment is off during wireless charging, the charging power may decrease, and significant misalignment can cause intermittent charging.
Additionally, using thick or metal phone cases can also lead to this issue.
Troubleshooting
Q1: Why does the Xiaomi UltraThin Magnetic Power Bank 5000 15W only charge an iPhone up to 80%, or sometimes fail to charge?
A: The Xiaomi UltraThin Magnetic Power Bank 5000 15W can only charge an iPhone to 80% or not charge at all for the following reasons:
1. The iPhone has enabled the “Optimized Battery Charging” feature, which slows charging after 80% by switching to trickle input. Path to toggle: [Settings] >> [Battery] >> [Battery Health & Charging] >> [Optimized Battery Charging]. You can turn it off and try again.
2. Running intensive tasks such as gaming, long video recording, or calls during charging can cause the iPhone to heat up. When the device temperature is high, the iPhone’s protection mechanism activates, which will slow down charging or even stop it.
Q2: Why does the charging indicator of the Xiaomi UltraThin Magnetic Power Bank 5000 15W blink again when plugged in after being fully charged?
A: After the Xiaomi UltraThin Magnetic Power Bank 5000 15W is fully charged, reconnecting it to a power source will re-enter the full-charge detection mechanism. The LED lights will return to a steady full-charge indication within approximately 10 minutes. This is a normal phenomenon.
Q3: Is it normal for all four indicators to blink simultaneously when the Xiaomi UltraThin Magnetic Power Bank 5000 15W is charging a device?
A: If no external device is connected, all four lights blinking together while the Xiaomi UltraThin Magnetic Power Bank 5000 15W itself is charging is an abnormal phenomenon. Please contact the after-sales service center for assistance.
Q4: Is it normal for the Xiaomi UltraThin Magnetic Power Bank 5000 15W to make current sounds or beeping noises when wirelessly charging a phone?
A: When the Xiaomi UltraThin Magnetic Power Bank 5000 15W discharges wirelessly, the capacitors may produce slight tapping sounds on the PCB. This is normal, and you can continue to use the device safely.
Q5: Why does the indicator on the Xiaomi UltraThin Magnetic Power Bank 5000 15W keep flashing when an Apple data cable is connected, but not the phone?
A: This is normal. Since the Apple data cable contains a chip, it consumes a small amount of current when plugged into the Xiaomi UltraThin Magnetic Power Bank 5000 15W. If the other end of the cable is not connected to a device, the power bank will intelligently recognize the cable as a "low-current device," causing the indicator to keep flashing.
Q6: Why is there a current noise when the Xiaomi UltraThin Magnetic Power Bank 5000 15W is charging a phone?
A: Different phones have varying current fluctuations during charging. For example, iPhones can experience current fluctuations of several hundred mA.
