Operating Instructions
Charging Your Devices
The NOBIS N2661 can charge up to four devices simultaneously using its two USB-C and two USB-A ports.
- Ensure the power bank is sufficiently charged.
- Connect your device to one of the available USB-C or USB-A ports using a compatible charging cable.
- The power bank will automatically begin charging your device. The digital display will show the remaining battery percentage.
Fast Charging (45W Max Output)
For the fastest charging speeds (up to 45W), connect a single compatible device to one of the USB-C ports. This is ideal for laptops, tablets, and fast-charge enabled smartphones.

Multiple Device Charging
When charging two or more devices simultaneously, the total output power is shared, typically up to 20W. This allows for convenient charging of multiple accessories, though individual device charging speeds may be reduced compared to single-device charging.

Trickle Charge Mode for Low-Power Devices
For charging low-power devices such as earbuds, smartwatches, or fitness trackers, activate the trickle charge mode to prevent overcharging and protect the device's battery.
- Double-press the power button on the side of the power bank.
- The digital display will indicate that it has entered trickle charge mode (e.g., by cycling one of the digits or showing a specific low-power indicator).
- Connect your low-power device.
- To exit trickle charge mode, double-press the power button again.
Using the Detachable Lanyard
The integrated lanyard serves a dual purpose: as a convenient carrying strap and as a built-in dual Type-C charging cable. To use it as a cable, simply unclip it from the power bank and connect it to your device.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the surface of the power bank. Do not use harsh chemicals or abrasive materials.
