All-in-One Power Bank with Built-In Cables

The No Sew K11 integrates a foldable wall plug, USB-C, iOS and Micro-USB cables so nothing extra is needed. Travellers and commuters can recharge phones or tablets directly from a wall socket or the internal 10000 mAh cell. The slim profile slips into a bag or pocket for daily carry.

Sustained Output Through Multiple Ports

Up to four devices draw power simultaneously from the built-in cables and the USB-A port without a noticeable drop in delivery. The lithium-polymer pack maintains steady voltage across repeated cycles, supporting up to 2.5 full phone charges during long flights or busy workdays. Heat stays low thanks to the efficient 3.85 V chemistry.

15 W Fast Charging via USB-C Cable

The integrated USB-C cable delivers 5 V at 3 A, pushing a compatible handset to roughly 50 % in 35 minutes. This single rate decides whether the K11 matches your speed needs; slower devices will charge at their own maximum. Buyers who require higher wattage or wireless charging should look elsewhere.

Questions about this item

How warm does the K11 get when it charges four devices at once all day?

The 10000mAh lithium polymer cell runs at 3.85 volts and delivers up to 15W through the built-in USB-C cable, so sustained multi-device use produces noticeable but moderate warmth.

What must I already own to start using the K11 right out of the box?

Nothing extra — the unit includes built-in USB-C, iOS and Micro-USB cables plus a foldable wall plug, so you only need the devices you want to charge.

Will the K11's built-in cables still fit the iPhone 12 and older models I keep?

Yes, the integrated iOS cable works with iPhone 6 through 17 Series, and the USB-A port accepts any legacy cable you already use for older gear.
