Newell USB-C 21700 Rechargeable Battery – 5000 mAh (2 Pack)

The Newell USB-C 21700 Rechargeable Batteries provide a powerful and reliable energy solution for demanding devices. This set includes two high-capacity lithium-ion 21700 batteries with 5000 mAh capacity, designed for long runtimes and dependable performance.

Each battery features an integrated USB-C charging port, allowing you to recharge the cells directly without the need for a dedicated charger. Simply connect the included cable to a power bank, computer, or USB wall charger for convenient charging wherever you are.

A built-in three-LED charge indicator provides a clear and easy way to monitor battery status at a glance.

Convenient USB-C Charging

With the integrated USB-C charging port, you can recharge your batteries using the included USB-A to dual USB-C cable, eliminating the need for a traditional battery charger. This makes them ideal for travel, outdoor use, and everyday carry.

If preferred, the batteries can also be charged using a compatible lithium-ion battery charger designed for 21700 cells.

Compatible with Many Devices

The 21700 battery format is increasingly popular in modern electronics due to its higher capacity and longer runtime compared to traditional 18650 batteries. These batteries are suitable for a wide variety of devices requiring reliable power.

  • Tactical and head flashlights
  • Power tools
  • Outdoor and camping equipment
  • Electronic measuring devices
  • Photography accessories
  • Microphones and other portable electronics

Their high capacity and durable lithium-ion design make them an excellent choice for professional and demanding applications.

Smart Charging Status Indicator

The batteries include a practical three-LED charge indicator that allows you to easily check the current charge level.

  • LED lights progressively illuminate as the battery charges
  • All three LEDs lit – battery fully charged
  • A quick press of the button on the battery displays the current charge level

This intuitive feature allows you to monitor charging without additional devices.

Long Lifespan and Reliable Performance

Each battery provides over 1200 charging cycles, making them a long-lasting and economical alternative to disposable batteries. Designed for intensive use, they are ideal for applications where reliability and endurance are essential.

Advanced lithium-ion technology also eliminates the memory effect, meaning the batteries can be recharged at any time without reducing their usable capacity.

Advanced Safety Technology

The Newell 21700 USB-C batteries incorporate an intelligent protection system to ensure safe and stable performance.

  • Protection against overheating
  • Protection against overcharging
  • Protection against overloading
  • High resistance to self-discharge

Even after months of storage, fully charged batteries can retain around 80% of their stored energy.

Practical Two-Battery Set

The pack includes two Newell 21700 rechargeable batteries, making it ideal for devices that require a pair of cells, such as flashlights or specialised equipment. A USB-A to dual USB-C charging cable is included along with a handy semi-transparent case to keep the batteries and cable organised and protected.
