Ready for daily carry

The NOBIS N2321 is a 10000mAh lithium-polymer power bank rated at 25W output. It targets smartphone users who want a single compact unit for commuting or travel without carrying separate cables.

Fits in a pocket

Measuring 14.2 in x 7.2 in x 1.9 in and weighing 238 grams, the slim profile slips into a jacket pocket or small bag. A built-in USB-C cable handles both input and output, while an additional USB-A port and a second USB-C port allow three devices to charge simultaneously.

Cable clutter removed

The integrated USB-C cord eliminates the need to pack a separate charging lead for most modern phones. An LED display shows the exact remaining capacity, and a low-current mode protects small wearables such as earbuds or smartwatches during charging.

Questions about this item

How many full phone charges does the 10000mAh capacity deliver before the power bank itself needs recharging?

The 10000mAh lithium polymer cell typically provides two to three full smartphone charges depending on the phone's battery size, with the LED display showing exact remaining capacity.

Does the 25W output cause the unit to become hot or noisy during extended charging sessions?

The slim 14.2 x 7.2 x 1.9 in design has no fan; it relies on passive cooling so it stays silent and only warms slightly under continuous 25W load.

Which cables must I already own to charge the power bank and a device with a Lightning port?

The built-in USB-C cable handles recharging the bank and USB-C devices; you only need your own USB-C to Lightning cable for Lightning-port devices.
