Checking the Battery Level
- Press the Power Button once.
- The digital display shows the current battery percentage.
- The display turns off automatically after a few seconds to conserve power.
- If the Power Button does not show a battery indicator, the power bank may have entered protection mode. Connect it to a compatible charger and begin recharging.
The displayed percentage is an estimate of remaining battery capacity.
Charging a Device with the Built-in USB-C Cable
- Gently pull out the built-in USB-C cable.
- Connect it to the charging port of a compatible phone, tablet or other USB-C device.
- Check that the connector is fully inserted and the device indicates charging.
- When finished, disconnect the cable carefully and return it to its stored position.
The built-in cable supports USB-C charging up to the rated output for compatible devices.
Charging a Device with the Built-in Lightning Cable
- Gently pull out the built-in Lightning cable.
- Connect it to a compatible device with a Lightning charging port.
- Check that charging has started.
- When finished, disconnect the cable carefully and return it to its stored position.
Charging speed depends on the connected device and its supported input.
Charging Through the USB-C Port
- Connect a compatible USB-C cable to the power bank's USB-C Input/Output port.
- Connect the other end to your phone, tablet, laptop or other compatible device.
- Check that the device's charging indicator appears.
- Disconnect the cable carefully when charging is complete.
The USB-C port can be used for both input charging and device output. Peak USB-C output is up to 35W when the connected device and cable support the required charging profile.
Charging Through the USB-A Port
- Connect a compatible USB-A charging cable to the power bank's USB-A output.
- Connect the other end to your device.
- Check that the device indicates charging.
- Disconnect the cable when finished.
Use a cable and power-bank output that are compatible with the connected device. Actual charging speed may be lower than the device's maximum.
Recharging the Titan 35
- Connect a compatible USB-C charging cable to the power bank's USB-C port or use the built-in USB-C cable as supported.
- Connect the other end to a compatible wall charger.
- Check the display for the remaining battery percentage.
- Allow the power bank to recharge.
- Disconnect it when charging is complete.
For best results, use a compatible USB-C PD charger and a good-quality cable.
Getting the Best 35W Charging Performance
- Confirm the connected device supports USB-C PD or PPS at the required power level.
- Use a compatible USB-C cable and charger.
- Use the built-in USB-C cable or USB-C port according to the device connector and supported profile.
- Keep the power bank uncovered so heat can dissipate.
- Charging output may vary with device demand, remaining battery capacity and temperature.
- Do not exceed the rated output capacity.
Charging More Than One Device
Titan 35 includes two built-in cables, a USB-C input/output port and a USB-A output. You can connect compatible devices using the available outputs.
- Check that each device supports its charging method.
- If charging is slower than expected with multiple devices connected, disconnect one device and test again.
- Do not assume each device will receive the full 35W at the same time; output may be shared across the connected devices.
Protection Mode
The power bank may stop working temporarily if it detects an abnormal condition, such as overcharging or over-discharging.
- Disconnect connected devices.
- Connect the power bank to a compatible charger.
- Begin recharging and check whether the display responds.
- If the power bank does not recover or behaves abnormally, stop using it and contact support.
Safety & Care
- Use the provided cable or a certified, high-quality compatible cable and charger.
- Charge the power bank on a flat, non-flammable surface.
- Do not charge it on a bed, sofa or near heaters or other flammable materials.
- Do not leave it charging unattended or plugged in overnight.
- Keep it away from water, moisture and direct sunlight.
- Do not store it in a pocket or bag with coins, keys or other metal objects while in use.
- Do not drop, crush, puncture, disassemble or attempt to repair the power bank.
- If it becomes unusually hot, unplug it and allow it to cool.
- Stop using it immediately if it becomes swollen, cracked, deformed, leaks or exposes wires.
- Carry power banks in hand luggage when travelling by air and follow airline rules.
- Dispose of the product through an authorised electronic-waste collection point, not household waste.
Storage & Maintenance
- Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures.
- For long-term storage, keep it around 50–60% charged.
- Avoid leaving it fully charged or completely depleted for a long time.
- Keep the cables and ports clean and dry.
- Disconnect the cable when the power bank or connected device is fully charged.
