Frequently Asked Questions - YB-30WW Yoobao
How do I check the battery level on my Yoobao YB-30WW?
Press the power button once. The LED indicators will light up to show the remaining charge: 4 LEDs = 75-100%, 3 = 50-75%, 2 = 25-50%, 1 = 0-25%. Charge when only one LED blinks.
Can I charge my phone and the power bank at the same time?
Yes, the Yoobao YB-30WW supports pass-through charging. Connect the power bank to a wall charger while simultaneously charging your device via the output ports.
What is the input and output specifications?
Input: USB-C PD 18W (5V/3A, 9V/2A). Output: two USB-A ports supporting Quick Charge 3.0 (5V/3A, 9V/2A, 12V/1.5A max each). Total output limited to 2.4A.
Is the power bank safe to use while sleeping?
Yes, it has built-in protection against overcharging, over-discharging, short circuits, and overheating. It is safe to leave charging overnight, but unplug when fully charged.
Why does my device charge slowly?
Ensure you are using a high-quality cable and that the device supports fast charging. The YB-30WW outputs up to 18W per port, but the actual speed depends on your device's compatibility.
Can I take the power bank on a plane?
Yes, power banks under 100Wh (like this 10000mAh model at ~37Wh) are allowed in carry-on baggage. Check airline regulations for specific limits.
How do I reset the power bank if it stops working?
Try a hard reset: connect the power bank to a charger and press the power button for 10 seconds. If that fails, let the battery fully discharge and recharge.
Does the YB-30WW support wireless charging?
No, this model does not have wireless charging. It only charges via the USB-A ports.
What should I do if the power bank gets wet?
Immediately disconnect all cables and dry the exterior with a cloth. Do not attempt to charge or use it until fully dry. If water entered the interior, dispose of it safely.
How long does it take to fully charge the power bank itself?
With an 18W USB-C charger, it takes approximately 4 hours. Using a lower wattage charger may take longer.
