Important Notes

n

n
• The product does not include a wall adapter; a standard USB-C or USB-A charger must be used for recharging the power bank.

n

• For first-time use, fully deplete the battery before initial recharge to optimize performance.

n

• If low-current devices like earbuds reach ~90% charge, the power bank may automatically shut off due to current mismatch—this is normal behavior.

n

• The touch button only functions in standby mode to check remaining power and does not serve as a physical switch.

n

• Package includes: 1x Portable Charger (with built-in cables), 1x Type-C USB Cable, 1x User Manual. Customer support responds within 12 hours for any issues.
