The Nitecore NL2150RX is a high performance USB-C bidirectional charging li-ion battery with a capacity of 5000mAh. Featuring a USB-C input and output, the battery can be used as a power supply to recharge electronic devices, such as smart phones and earphones.

The battery can be recharged via the USB-C charging port (cable not included) or in an external charger, such as the Nitecore Ci2, Ci4, UMS2 or UMS4 (sold separately). When charging with the built-in USB-C port, the red indicator on the top of the NL2150RX will change from flashing red to constant red once complete.

The Nitecore battery has a range of safety features, including:

  • Integrated smart charging circuitry in the anode to protect against overcharge, over discharge and short-circuit
  • Built-in PTC to inhibit high current surges
  • Microporous barrier protects delicate internal components
  • Pressure relief valve protection activates in the event of rapid temperature increase
  • Nickel-plated stainless steel protectors at both ends of the battery for resistance to impact and oxidation and promotes good electrical conductivity
  • Coated with durable metallic film to guard against abrasion
  • Tough plastic circuit board protector
