Replace the battery, not the power bank. Modular power that's eco-friendly, recyclable, and built to move.
Meet the KangTao Smart N6-RB — a compact power bank built on a replaceable 21700 battery. Swap in a charged battery and keep going. 22.5W fast charging, 55g, and a rotating ring for stress relief.
Four distinctive finishes — same modular power system inside. Only the look changes, never the performance.




With a simple push, remove the depleted 21700 battery and swap in a charged one in seconds. Replace the battery, not the power bank.
Up to 22.5W fast charging with multiple protocols — PD, QC, FCP, AFC, and PPS — for efficient power across a wide range of devices.
A built-in rotating ring that spins smoothly between your fingers — a satisfying tactile stress-relief element on a compact 55g power bank.
No studio tricks. Shot on the desk, in the hand, on the phone — exactly how it carries.







Each 21700 battery gives you 5000mAh. Carry extra batteries separately and swap them in seconds whenever you need more power — replace the battery, not the power bank.

"Bought it for the battery. Kept it for the flip. I've spun this thing through three meetings today. My fidget cube is officially retired."
"Butterfly Green goes stupid hard with my setup. Two spare 21700 batteries in the sling bag = I'm the charger plug of my friend group now."
