Does it support fast charging for the new 21700 battery cells? I’ve been looking for a charger that can charge my batteries quickly without overheating?
Imran Hanafiah –
Thank you for sharing your interest in the Nitecore i2 Charger’s fast charging capabilities for 21700 battery cells, Cecilia! Our charger is designed to charge batteries efficiently and safely, but I’d like to clarify that its maximum charging rate is 1000mA. While it can charge these cells, it may not be the fastest charger available on the market. However, overheating is minimized thanks to our intelligent temperature control system. If you’re looking for a charger with even faster charging capabilities, we recommend considering our other options such as the Nitecore i4 Charger.

Can the charger be connected to a power bank to keep it powered while using it outdoors?
Junhao Lo –
Thank you for sharing your thoughts about Nitecore i2 Charger, Sophia Goh! The Nitecore i2 Charger is designed to be a compact and portable charger, making it perfect for outdoor use. However, it is not recommended to power the charger from a power bank. Instead, it can be powered by a USB port, which provides a stable 5V DC output. The charger comes with a built-in battery-saving circuit that protects it from over-discharging, ensuring your batteries are safe and healthy. For powering the charger itself outdoors, we recommend using a USB-rechargeable power source or a portable USB power adapter.
