Nitecore has introduced a new power bank during IWA 2026. The Carbo 20 is a bigger model compared to the lightweight Carbo 10000, providing 20,000mAh of power instead of 10,000mAh. Thanks to Nitecore’s use of a higher voltage, this new model offers more power than other 20,000mAh power banks, specifically 78Wh. Additionally, Nitecore claims that their power banks charge devices with higher efficiency. Generally, Nitecore’s products are said to deliver about 30% more energy, although this can vary based on the output needed.

Efficiency and Specs

The efficiency of the power bank tends to decrease as the wattage increases. While detailed technical specifications have yet to be released, the Carbo 20 supports charging and output of up to 65 watts (3.25A at 20V). This makes it capable of powering laptops and larger gadgets.

Design and Features

For its construction, Nitecore continues to use carbon fiber reinforced plastic, also known as carbon. This material keeps the power bank lightweight while ensuring it remains durable and waterproof. The weight is mentioned at 13.4 oz, making it relatively light, though the Carbo 20 does add some heft. In contrast, Nitecore’s Summit 20000 (77Wh), which is designed more for smartphones, weighs about 10.6 oz and provides only 22 watts. It can handle temperatures as low as -40°F and has a built-in heater, which the Carbo 20 lacks, positioning it as an everyday power bank.

The device features a small status display that indicates remaining capacity in percentage, which is quite uncommon for Nitecore. There are two USB-C ports for charging other gadgets, with one also used to recharge the power bank itself. The Nitecore Carbo 20 is anticipated to be available in Q2 2026. While an exact price has not been announced, it is likely to be on the pricier side. For reference, the Carbo 10000 Gen 2 is priced at $119 in the US.
