Good travel charger
Good universal charger for travel and speedy use. Can even just keep it in the bag charging off of a battery pack. Have charge up to a 21700 so far with no problems

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.

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.

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).

Charges 21700 and 18650 cells with no issue.
Not much to say except that it works, and the cable it comes with is good, too.
