Yes. The ROMOSS 20000mAh Power Bank is airline friendly and complies with IATA regulations for carry-on luggage. Its capacity (74Wh) is within the permitted limit for most international airlines.

Q2: How many times can it charge my phone?

It depends on your phone's battery size. For a typical 4,500mAh smartphone, you can expect 3–4 full charges. For smaller phones (3,000mAh), you may get up to 5 charges.

Q3: Does it support fast charging for iPhones and Android phones?

Yes. The 22.5W output is compatible with most Android fast-charging standards (Huawei FCP, Qualcomm QC). For iPhones, fast charging is supported via the USB-C port with a compatible cable.

Absolutely. The power bank features 3 output ports, allowing you to charge up to 3 devices simultaneously. Note that total output power is shared across all connected devices.

Q5: How long does it take to fully recharge the power bank itself?

Using a 22.5W USB-C charger, the power bank can be fully recharged in approximately 4–5 hours. Using a standard 5W charger will take significantly longer.

Yes. The Multi-Protection Safety System automatically stops charging once your device reaches 100%, preventing overcharging and protecting battery health.

Q7: What is the low current mode used for?

Low current mode is designed for charging small, low-power devices such as wireless earbuds, smartwatches, fitness bands, and Bluetooth speakers that may not trigger standard charging thresholds.

Yes. This product comes with a 6-month warranty covering manufacturing defects. Please retain your purchase receipt for warranty claims.
