Product information

Description

The Nitecore NB20000GEN3 Power Bank 20000 mAh is a compact, lightweight external battery designed to deliver reliable portable power for smartphones, tablets and low-current accessories. Built with a carbon-fiber-reinforced polymer frame and woven carbon fiber panels, it balances strength and reduced weight while offering pass-through charging and dual USB-C ports for flexible connections. The unit meets UN38.3 requirements and has a rated capacity under 100 Wh, making it airline-friendly.

Advantages

The NB20000 Gen3 is significantly lighter and smaller than conventional 20,000 mAh power banks, with a 13% reduced length versus the previous model and a compact size shorter than an iPhone 15 Pro. The carbon fiber construction and reinforced composite anti-torsion structure improve impact resistance while keeping weight low. Four corner cushions provide extra shock protection and a secure grip, and the included USB-C to USB-A adapter increases compatibility with different cables and devices. Dual USB-C ports support pass-through charging and multi-protocol fast charging, with auto-detect down to 60 mA for low-current devices.

Suitable for

  • Charging smartphones and tablets while traveling
  • Powering headphones, wearables and other low-current accessories
  • Outdoor activities where a lightweight portable battery is preferred
  • Air travel with a power bank under 100 Wh

Key specifications

  • Battery capacity: 20000 mAh (rated voltage 3.6 V)
  • Output: Dual USB-C ports, pass-through charging
  • Fast charge support: up to 22.5 W for compatible devices
  • Minimum detection output: 60 mA for low-current devices
  • Construction: carbon fiber reinforced polymer frame with woven carbon fiber panels
  • Protection: 4 corner cushions and 12-machine-key secured composite structure
  • Weight: 0.291 kg
  • Colour: Black
  • Certifications: UN38.3; capacity <100 Wh (airline approved)

How to use

Connect your device to one of the USB-C ports using an appropriate cable or the included USB-C to USB-A adapter. To recharge the power bank, connect a USB-C charger to a USB-C port; pass-through charging allows the power bank to charge connected devices while it recharges. The NB20000 Gen3 will automatically detect connected devices and apply the appropriate charging protocol, including low-current detection for accessories that require as little as 60 mA.

Usage recommendations

Use a compatible PD-capable USB-C charger for faster recharging of the power bank and avoid exposing the unit to extreme temperatures. Store the power bank partially charged if not used for long periods and carry it in a protective pocket or case to maintain the integrity of the carbon fiber panels and corner cushions.

Design

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
