Charging Times & Capacity
How long does it take to charge the INIU 20000mAh power bank to full?
Recharging the bank itself via its USB-C PD input takes roughly 5–6.5 hours with an 18–22W charger. Full charge time depends on your adapter wattage.
How many times can it charge an iPhone 15?
The 20,000mAh capacity delivers roughly 4 full iPhone 15 charges, and PD 22.5W fast charging boosts an iPhone 15 to about 65% in 25 minutes.
Does it support pass-through charging?
