How long does it take to fully charge the CEN-TECH 3-in-1 Portable Jump Pack?

[VonIris]

To get your CEN-TECH 3-in-1 Portable Jump Pack ready to go, expect an initial AC charge time of up to 48 hours. For subsequent charges, the jump pack typically takes up to 30 hours to fully recharge. Keep in mind that it's crucial to fully charge the unit after each use and to recharge it monthly to maintain optimal battery health. The charging indicator lights will change from red to yellow to green during charging. The green light indicates a full charge, so unplug the jump pack once it's reached this stage to prevent overcharging.
