i Series Battery Charger & Powerbank

The Nitecore F21i turns your iSeries battery such as NL21500HPi into a minimalist battery charger and power bank. The F21i features a USB-C port that functions both as a battery charger when connected to a power adapter and as a power bank when connected to a device. The 3-dot blue indicator beneath the USB port flashes to indicate the charging progress. Supporting Quick Charge and Power Delivery (QC, PD) protocols, F21i delivers an incredible 18W of fast charging output. The F21i is a mini multi-functional battery charger and power bank as well as a must-have backup battery and accessory for any iSeries tactical flashlight.

Tough and Light

The F21i is ultra-compact, durable and safe to use. It is about 2 inches long when stowed away and only 4 inches long when fully stretched. Its rigid battery cap is made from fire retardant polycarbonate. It also comes with the same comprehensive safeguards as the other Nitecore chargers: overcharge protection, overcurrent protection, over-discharge protection, short-circuit protection, thermal protection, and overvoltage protection. Always be prepared by pairing a F21i with a iSeries battery for emergency power.

5 of 5 Love the F21i - Bring it back! June 13, 2023
Reviewer: Jesse  
I had finally found my perfect on trail charging solution... and then you discontinue the product.  I regret spending so much on the batteries only to be left without any equivalent options for a replacement of the F21i if I ever loose it, or it breaks.  Please bring it back.  You could make then new version out of carbon fiber, then everyone would oooh and ahh just like with the NB1000.

5 of 5 Great little charger August 1, 2022
Reviewer: Kevin Tompkins from Texas  
This thing is SMALL.  I mean shirt pocket small.  And fast.  I charge several of the “i” series 5000 mah batteries that go along with my P10ix.  It not only charges quickly, but it’s there in case I need reserve power because it acts as a power bank.  I just love the convenient size.
