Compact USB charger praised for portability and ease of use. Customers said it "charges fast" and is "exactly what I needed." Most report reliable performance with multiple battery sizes. Some noted slow charging times (9+ hours for larger batteries) and one reported it never charged 26650 batteries. Build quality described as sturdy despite low price.
When I plug it into usb adapter the blue lights flash for the one min. However it never charges the battery.

JIST WHAT I NEEDED ! THANKS
Charges fast
Very happy with the charge, small and inexpensive, and exactly what I needed.
Good price fast shipping and charges the battries
You have asked for a review before I have received the product. It is supposed to be delivered later today.
I can now "hot swap" batteries in my MH25 Pro. Before I could only charge my batteries through the USBC port in my flashlight. I have also been able to charge my other batteries that for in the charger. For the priceI am happy with it.
Compact and easy to carry.
Works like a charm
It charges my batteries at a slower charge - I want to give my batteries a little less stress and hopefully longer lifespan and this affordable charger does this. I think it is great value.
Everything went fine. Ordering and shipping were all good. thank you Nitecore.
I love the simple and compact design. Pretty sturdy build would definitely recommend to other.
Inexpensive yet well made charger. Performed flawlessly
Exactly what I ordered. Came quickly.
good service
Great charger, easy and intuitive to use. Works well and charges quickly.
I have other nitecore chargers ,however, I cannot always carry those larger multi bank chargers with me. This single battery charger is just right for those light carry occasions. Also, it’s not thin plastic, but built sturdy enough to withstand bumps along the way.
Received my batteries and charger in time to take them on my diving trip. Thanks for the quick delivery!
This is a great charger for many sizes
of batteries I use. It work as advertised
and I like it.
I was only going to order a spare battery and the UI2 but then I would have had to pay for shipping so I also ordered this to put me over the limit. When I travel, this will be my go to charger for all of my batteries. Wishes...I wish it had the USB-C connector to be compatible with my cell phone's charger cable.
Very simple to use and easy to see at a glance when it’s charging or fully charged. Takes so many battery types!!
The best products in the market by far
I use 18650 batteries exclusively. I already have a 4 cell charger I use often but I needed a singIe cell charger for small/quick jobs that had a USB source, and the Nitecore Ul1 fit my needs perfectly. I always use the best, I buy the best batteries and they are taken care of by the best chargers, this is why I use Nitecore.
This will be a great addition to my gear setup. I like that I can observe and actually have a read out with status of the charging of batteries.
It was great for charging all sizes of batteries
Takes a long time to charge 21700 battery so I’ll probably buy backup battery but works perfectly.
I like the simplicity to be able to charge my batteries and the device to tell charge status.
Charges NL2150hpi batteries for I series flashlights fine. Yeah I know the flashlights use USB integrated. It’s nice to be able to charge spares though.
This is a super fast charger. Small and packable.
Outstanding product and well made/designed!!
The charger works great and stops charging to protect the battery from over charging and causing damage to the charger or battery itself. I keep a charger at work and charger at home. Plus the E4K flashlight came with a usb c cable to charge so you can also use that to charge the battery in your car or truck while on the road. No need to carry the charger itself from place to place.
very happy with this purchase
