    works great, except...

    Posted by doug on 12th Sep 2018

    it will not charge some smaller electronics like headlamps. read up on reddit and elsewhere of user experiences before purchasing. I wanted to like this, but it just doesnt fit my application. I ended up buying a nitecore f1 which does not have this problem.

    Just what I needed

    Small enough to be convenient to carry, but still enough capacity to be worth carrying. 18640 battery makes it versatile.

    Charger is exactly how it's described. It works awesome and I use it everyday. I love how I can use it to charge up my 18650 batteries for my flashlight as well as charge other things. I couldn't ask for a better product

    I love it. Use it regularly.

    Posted by Howard on 2nd Oct 2017

    Nothing else like it currently available on the market and I find I use it often. Great option for keeping an extra 18650 battery with you. You can use it as a spare 18650 battery at the ready, use it to charge a 18650 (charging time is rather slow), and use it to charge your cell phone. When my iphone is at 20% battery (the point at which the iphone begins to whine), I can plug it into the C2 with a charged battery and fully recharge my iphone (using the included battery) in a relatively short period of time thanks to the high current output of the USB port. Charging an 18650 battery in the C2 can take upwards of 5+ hours. Fine if you're charging overnight, but not if you're in a hurry. The C2 can also tell you the rough voltage level of the battery through the multicolored led which is activated when you depress the power switch. It's very compact, with the total package being only slightly larger than the battery itself. I love this product and use it almost everyday for one purpose or another. It's now part of my EDC arsenal. What's not to like.. spare 18650 battery, phone charger, and a compact travel/emergency battery charger... and you get a 3400mAh 18650 battery all for just a little more than what you pay for the battery by itself. Don't think about it any longer and just buy it. Makes a great gift for anyone who owns a product (or two) using 18650 batteries. Very highly recommended
