Solid piece of gear
Great for portability, this little charger makes peace of mind a reality, especially on those long trips away from ready access to grid power. I bought this for camping, and specifically because it will work with my external battery pack, so I have now consolidated my charging requirements into a single form-factor for cable/battery/charger/phone. The only thing I would have done differently would be to add the capability to dim or disable the charging LED, since it is SO bright. It's a small, blue, 3-segment charge indicator, but you could nearly light up your whole tent with the LEDs. Little bit of gaffer's tape takes care of that. Very pleased with the purchase, and would buy again, if needed. Nitecore produces top-notch products that won't let you down.

it works; usb-c
It works well for charging a14500 battery. The 3 LEDs give an indication of the state/percentage of charge, I like that. I noticed the description and reviews mention a Micro-USB port, but mine came with a USB-C port (I’m guessing it’s a newer version).

Nice Charger but Micro-USB
This charger is easy to use and small enough to take anywhere. Drawbacks include the micro-USB connector and its relatively cheap feel. I wish it were USB-C. Other than those issues, it has worked on a variety of rechargeable batteries.

Updates include USB-C and 1000mA charging
The Ul1 charger is now USB-C. - It reliably worked with both flat top 18650 and 21700 protected button top batteries. This is important as not all chargers work with these long batteries. - The rubber feet help with grip. I am able to use a heavy cord without it falling off the night stand. - Update. After using it for a bit, keep in mind that it takes hours for large batteries. They stay cooler compared to other chargers I have used, which is better for longevity and safety. - I liked it enough, that I purchased a second unit.
