The Power Bank 10000mAh JC-21 is a portable charging solution designed to provide reliable power to your devices while on the go. With a 10,000mAh capacity, it offers enough power to recharge smartphones, tablets, or other USB-powered gadgets multiple times, making it ideal for travel, outdoor activities, or situations where you need a backup power source.

Key Features of the Power Bank JC-21 (10000mAh):

1. Battery Capacity:

• 10,000mAh Capacity: Provides a substantial amount of charge, typically enough to recharge most smartphones 2 to 3 times depending on the phone’s battery size. It’s also capable of charging tablets and smaller devices like Bluetooth headphones, smartwatches, and more.

2. Charging Ports:

• Dual USB Output Ports: The JC-21 features two USB-A output ports, allowing you to charge two devices at once. Each port can typically provide an output of 5V/2.1A, which is enough to charge most devices quickly.

3. Input Power:

• Micro-USB Input: The power bank is charged via a Micro-USB port with an input power of 5V/2A. This means it can be recharged fairly quickly (within 4 to 6 hours) using a compatible charger.

4. Fast Charging:

• Output Current of 5V/2.1A: This allows for relatively fast charging of devices, especially compared to older power banks that only offer 1A output. While it may not support the fast charging standards like Quick Charge or USB-C PD (Power Delivery), it still offers decent speed for most devices.

6. Battery Indicators:

• LED Battery Indicators: The power bank comes with 4 LED lights that show the remaining battery life of the power bank. Each light typically represents 25% of the total charge, so you can easily see how much power is left and when it’s time to recharge the power bank.

7. Safety Features:

• Overcharge Protection: Prevents overcharging of your devices and the power bank itself, ensuring safe operation.
• Overcurrent Protection: Guards against drawing too much current, which could potentially damage the connected devices.
• Short Circuit Protection: Prevents electrical damage caused by short circuits.
• Overheating Protection: Ensures the power bank doesn’t overheat during charging or discharging.

8. Compact Design:

• Slim and Portable: With a compact design, it’s easy to carry and use while traveling, commuting, or on the go. It typically measures about 130mm x 70mm x 15mm, which makes it ideal for users who need a power source that's not too bulky.

  • Smartphones (iPhone, Android, etc.)
  • Tablets
  • Bluetooth headphones
  • Portable speakers
