Nitecore Intellicharge F1 Smart Charger

Charge Your Batteries and Your Devices!

The newest edition to Nitecore's line of battery chargers, the Intellicharge F1 Smart Charger is one of the most convenient and versatile chargers on the market. At less than 4 inches in length, this pocket-sized single channel battery charger is capable of charging a wide variety of Lithium-Ion batteries, from popular sizes like 16340 and 18650 to less common ones like 17335 and 18490. When installed with a Li-Ion battery, the F1 also doubles as a portable power bank, charging devices via its USB port output. All battery sizes fit securely in the charging bay thanks to the included rubber band, which keeps the battery in place even when it is being carried around. The charger is made of durable, fire retardant ABS plastic, making it safe to use whether you're charging your battery or your device.

PLEASE NOTE: Micro-USB cable (sold separately) required for use. We recommend the XTAR Micro USB Cable.

Throw this in your travel bag
July 1, 2016
Hardly bigger than the 18650 battery that it can charge, this charger is perfect for traveling. Not only will it charge all your batteries, but keeping a spare battery loaded in means you also have a spare USB power supply to charge your other devices. Thoughtfully designed, good quality, small, and affordable.
  • Very small
  • USB input AND output
  • affordable
  • Does not charge NiCd/NMH

Great for travel
May 16, 2019
Have a keychain EDC and two RCR123A batteries, Use frequently at work and home, day and night. Lots of over the road driving, out of town. With this little charger in my truck, can always charge one battery while using the other. All my lighting gear is Nitecore. When I find a quality brand I stick with it.

Great concept, but very slow charger
March 1, 2019
I bought this charger as part of a bundle.

This charger is more for convenience and not for speed. I like how it can be used as a power bank. I put a Nitecore 3500 mah 18650 in it that was 2/3 charged and it took over four hours to complete. The bands are not convenient to use and are a bit difficult. Much like using a rubber band that is too small. I think Nitecore should have attached some type of elastic band onto the charger, instead of including wide rubber bands. You will need something to secure the battery because it can fall out very easily. It does not come with the needed USB cable either.

Great for camping when traveling light is a must, works with solar power panels usb output. Comes two Nitecore brand rubber band (Yellow/Black) to secure the battery in place. Can also use the battery unit and charge mobile device(s)
  • Light weight and rubber band secure battery in place
  • Need to be upgraded to usb type C in the future .

Limited Use, but a very lightweight Charger
January 11, 2018
This is a great lightweight charger. It is good if you strictly use Li-Ion batteries. If you are looking to charge AAs, etc look elsewhere. Very small and compact design. Only flaw is that the the bands must be used to hold the battery in place if on the move. If not the battery instantly pops out. Also the bands are slightly too small. I use the band and occasionally use a regular rubber band. It has a suggested use for recharging batteries with using a solar panel and works well for this. This is not a primary charger and is not my primary travel charger (lack of AA charging). However, it is still a very good, simple charger
  • Small, Lightweight
  • USB output
  • Charger light, indicator
  • Only Li-Ion
  • Could use better bands to secure battery while mobile
