The Nitecore Carbo 20 is a rugged power bank built for outdoor use, pairing a one-piece carbon fibre shell with magnesium alloy honeycomb heat sinks to manage heat during high-power charging. A 20000 mAh cell delivers 76 Wh of energy, with around 67.5 Wh usable at 5V/3A output. Two USB-C ports handle both input and output, supporting 65 W two-way fast charging over PD, QC 3.0 and SCP. A built-in display shows battery percentage and charging status, while an MCU paired with dual NTC thermistors monitors temperature in real time, backing up protection against overcurrent, short-circuiting, over-discharge, overcharge and overvoltage faults. An IPX8 rating allows submersion to 2 metres, making it suited to wet or demanding field conditions.
Features
- 65W Two-Way Fast Charging: USB-C PD, QC 3.0 and SCP support fast recharging, and the same charging speed can be delivered to a connected device.
- Unibody Carbon Fibre Shell: A one-piece carbon fibre body with magnesium alloy honeycomb heat sinks keeps the pack light while dissipating heat under high-power charging.
- IPX8 Waterproof Rating: Sealed against water ingress and submersible to 2 metres for wet or demanding outdoor use.

Lithium-ion Battery warning: All Li-ion batteries have a risk of fire and/or explosion. Handle the powerbank with care, ensuring not to overcharge or over discharge, even if the battery contains a protection circuit. If powerbank is visibly damaged, stop use immediately and dispose of appropriately (Li-ion batteries pose a serious fire risk if thrown into household waste). If a powerbank is not to be used for over two weeks, store partially charged (30-50%) for maximum capacity retention.
