3. Setup

Initial Charge:

Before first use, fully charge your ROMOSS power bank. This ensures optimal battery performance and longevity. The power bank is not pre-charged upon purchase.

1. Connect the provided USB charging cable to one of the input ports on the power bank (Micro USB, Type-C, or Lightning).
2. Connect the other end of the cable to a compatible USB wall charger (18W PD charger recommended for fastest charging).
3. The LED indicators on the power bank will illuminate to show the charging progress. All four LEDs will be solid when fully charged.

Using an 18W fast charger, the power bank can be fully recharged in approximately 7-8 hours. The "One Cable for All" design allows you to use the same cable for charging your phone and recharging the power bank, whether it's an iPhone (Lightning), Android (Micro USB), or a device with USB-C.

4. Operating Instructions

Charging Your Devices:

The power bank can charge up to three devices simultaneously using its USB-A and Type-C output ports.

1. Connect your device's charging cable to one of the output ports on the power bank (USB-A or Type-C).
2. Connect the other end of the cable to your device.
3. The power bank will automatically begin charging your device. The LED indicators will show the remaining battery level.

The power bank's intelligent charging technology (Sense6+ Fit-charge) automatically detects the connected device and delivers the optimal charging current, ensuring fast and safe charging.

For devices like the iPhone X, the 18W PD output can charge up to 50% in just 30 minutes, significantly faster than standard chargers.

The 20000mAh capacity allows for multiple charges: approximately 7.3 charges for an iPhone X, 6.6 charges for a Samsung S8, and 2.6 charges for an iPad mini 3.

Checking Battery Level:

Press the power button once to check the remaining battery level. The LED indicators will light up, with each light representing approximately 25% of the battery capacity.

• 1 LED: 0-25%
• 2 LEDs: 25-50%
• 3 LEDs: 50-75%
• 4 LEDs: 75-100%

5. Maintenance
