To charge your power bank, simply connect it to a power source using the included USB cable. This can be done by plugging the USB cable into either your phone charger or a computer USB port. Once connected, the power bank will begin charging automatically. Leave it connected until it reaches full capacity. Afterward, you can disconnect it from the power source. Your power bank is now ready to provide portable power for your devices.

The term “mAh” stands for “Milliamp Hours,” which is a unit of measurement used to indicate the capacity or amount of stored energy in a battery. When it comes to power banks, the mAh rating plays a crucial role in determining how much energy they can transfer to recharge devices like cell phones.
The higher the mAh rating of a power bank battery, the greater the amount of time and energy it can provide to recharge electronic devices. In practical terms, a power bank with a higher mAh rating will have a larger capacity, allowing it to deliver more charges or extended usage time for your cell phone or other electronic gadgets.

So, when choosing a power bank, consider the mAh rating as an important factor to ensure you have enough stored energy to keep your devices powered up when you need them the most.

The initial charging of your portable charger may take up to 14 hours. This longer charging time is due to the extended lifespan and higher capacity of our chargers compared to typical power banks. However, this initial investment of time ensures that you have days of power at your disposal. With its impressive charging capacity and extended usage time, our portable charger stands out as one of the most reliable and useful power banks available in

The number of times a power bank can charge a device depends on the capacity of the power bank and the battery capacity of the device being charged. For example, using our 20,000mAh power bank and a smartphone with a 3,000mAh battery, you can expect to get approximately 5-6 full charges for your device from the power bank.

While it is technically possible to charge the power bank while simultaneously using it to charge a device, it may affect the charging speed or efficiency. It’s recommended to charge the power bank separately and then use it to charge your devices for optimal performance.

The holding time of our fully charged power bank depends on the devices you are charging. Generally, power banks can hold their charge for several months if left unused. However, it’s recommended to recharge the power bank every few months to maintain its optimal performance.

Our power banks are designed with user-friendly features to keep you informed about the remaining power. Each power bank is equipped with LED indicator displays that show the current power level. With a simple press of the power button or a glance at the LED indicators, you can easily determine how much charge is left in your power bank.

No, our power banks are designed with built-in safety mechanisms to prevent overcharging. Once your device reaches its full charge, the power bank will automatically stop supplying power, ensuring that your device is not overcharged. This feature protects both your device and the power bank from potential damage.
No, power banks are not intended for jump-starting cars. The power output of a power bank is not sufficient to provide the necessary energy to start a car’s engine. It’s important to use proper car jump-starters or seek professional assistance in such situations.
The power banks are compatible with a wide range of devices that can be charged via USB, such as smartphones, tablets, portable speakers, Bluetooth headphones, and more. However, it’s important to ensure that your device’s charging cable is compatible with the power bank’s USB output port.
