K=A reinforced core.

The hardness ranking of carton materials is as follows: K=K > K=A > K=B > K3K > K2A > K3B.

ALOVA engineers have achieved maximum sweat resistance in our products through effective internal structural design, the use of manual/automatic glue dispensing machines, and applying a nano-coating on the PCBA (Printed Circuit Board Assembly).

It supports up to 500 recharge cycles. After 500 cycles, the battery performance may decrease, but it will not be damaged.
