| FUNCTIONALITY |
| How do I check the remaining battery level? | Simply press the power button once and the 4 LED indicators will light up to show your current battery level. |
| How fast can the BU054 charge my device? | The BU054 delivers up to 35W of Power Delivery (PD) fast charging via the USB-C port or built-in USB-C cables when charging a single device, and up to 22.5W via the USB-A port. |
| Can I charge multiple devices at once? | Yes, you can charge up to 4 devices simultaneously. When 2, 3, or 4 ports are used at the same time, the total combined output is 5V/4A (20W) shared across all connected devices. |
| How do I recharge the power bank? | You can recharge the BU054 in two ways. Plug it directly into a wall outlet using the built-in foldable AC plug, or connect a PD charger to the USB-C port or built-in USB-C cable for up to 35W input. |
| Does the BU054 support pass-through charging? | Yes, pass-through charging is supported when the power bank is plugged into a wall outlet. Your connected devices will charge first, then the power bank's internal battery will recharge to help preserve battery life. Please note that pass-through charging is not available in battery mode. |
| Can I use the USB-C port while the AC plug is in use? | Yes, the USB-C port still works when the AC plug is plugged into a wall outlet, but it will function as output only during this time. |
| Why does my power bank turn off when I try to charge my earbuds or smartwatch? | Low-power devices like earbuds and smartwatches draw very little current (less than 10mA), which the power bank may interpret as no device being connected. To keep the power bank awake while charging these accessories, please activate Low Current Mode by double-pressing the power button. |
| How do I use Low Current Mode? | Double-press the power button to activate Low Current Mode. The LEDs will display a flowing animation to confirm the mode is on, and your low-power device will charge continuously for up to 2 hours. |
| How do I exit Low Current Mode? | You can exit Low Current Mode by double-pressing the power button again or by long-pressing the button for 3 seconds. The mode will also automatically turn off after 2 hours to conserve battery. |
| Can I check the battery level while in Low Current Mode? | Yes, just press the power button once while in Low Current Mode. The current battery level will display for 3 seconds before returning to the flowing LED animation. |
| How do I wake the power bank from sleep mode? | You can wake the BU054 by pressing the power button once or by connecting a device. The power bank will also automatically wake when it detects a phone has been plugged in. |
| Why doesn't my power bank wake up when I connect a USB-C to Lightning cable? | When the power bank is in sleep mode and an empty USB-C to Lightning cable is connected, automatic detection may not activate. Please press the power button or reconnect the cable to wake the power bank manually. |
| Why does my power bank slow down during long charging sessions? | To protect the battery and prevent overheating, the BU054 maintains full 35W output for the first 30 minutes (at 25°C) or 20 minutes (at 35°C), then automatically reduces to 20W until the battery is depleted. When charging from a wall outlet in AC mode, no slowdown occurs. |
| Can I use the built-in cables to charge my phone when the power bank is plugged directly into a wall outlet? | Charging a phone via the dual short cables should not be expected when the AC power bank is plugged into a wall outlet. This only works if the outlet is on or immediately above a table. The cables are not designed to support the weight of a phone. |
| What happens when the power bank runs out of battery? | When the battery is fully depleted, the first LED will flash 5 times quickly and then turn off. Simply plug the BU054 into a wall outlet or USB-C charger to recharge it. |
