Q1: How many times will this charge my phone?
A: Charge count varies by device, but the 20000 mAh capacity typically provides 2–4 full charges for most modern smartphones depending on battery size and usage.
Q2: Can I charge two devices at the same time?
A: Yes. The PB400 Pro supports simultaneous charging via its USB-C and USB-A ports. Total output is managed by the smart power distribution system.
Q3: Is the power bank safe to carry on flights?
A: Most airlines allow power banks up to 100 Wh. A 20000 mAh 5V unit is typically under this limit, but we recommend checking airline rules and packing it in carry-on luggage.
Q4: How long does the power bank take to fully recharge?
A: Recharge time varies with charger used. Using a high-power USB-C charger, expect faster replenishment — typically a few hours. Using a standard 5V charger will take longer.
Q5: Does it support fast charging for iPhone and Android?
A: Yes. The USB-C PD and QC-compatible USB-A output supports fast charging profiles used by many iPhones and Android phones for quicker top-ups.
Q6: What warranty and after-sales support do I get?
A: This product includes a 1-year manufacturer warranty. Vlebazaar offers purchase support, warranty claim guidance and easy returns if eligible.
