Ready-to-go power for daily carry

The No Sew N2321 is a 10000mAh lithium-polymer power bank rated at 37Wh with a 6000mAh rated capacity at 5V/3A. It delivers up to 25W maximum output through USB-C Power Delivery and PPS protocols, plus USB-A fast charging. A built-in USB-C cable doubles as a carry strap, so you can charge a phone, tablet and a second device simultaneously without packing extra cords.

Check your device ports and voltage needs

The bank supplies 5V/3A, 9V/2.77A and 12V/2.1A from its USB-C port and 5V/3A, 9V/2.22A, 12V/1.67A from USB-A. Verify that your phone, tablet or accessory accepts one of these voltage steps; older gear limited to 5V/1A will charge but not at the advertised speed. Recharging the bank itself requires a charger capable of 5V/3A, 9V/2A or 12V/1.5A input over USB-C.

Slim profile with integrated cable management

Measuring 142×72×19mm and weighing about 238g, the unit slips into a jacket pocket or small bag. The tethered USB-C cable removes the need to carry a separate lead and can be looped around a strap or carabiner for hands-free carrying. Three output paths — built-in cable, extra USB-C port and USB-A port — let you top up multiple devices at once during travel or long work sessions.

Questions about this item

Does the power bank come with a built-in cable or do I need to buy a separate Type-C cable?

A Type-C cable is built into the unit and doubles as a carry strap. No separate cable is required for Type-C devices, though you may want your own cable for the USB-A port.

Should I choose this 10000mAh model or look for a different capacity?

This model provides 10000mAh (37 Wh) with a rated output of 6000mAh at 5 V / 3 A. It can charge a typical smartphone up to two times, making it suited for day trips or commutes.

What does the 25 W rating mean when I plug my phone in?

The Type-C port can deliver up to 25 W (12 V / 2.1 A) and the built-in cable supports the same bi-directional rate. With a compatible phone you can reach roughly 50 % charge in under 30 minutes.
