Nice small format for battery charger.
Like compact size, low-moderate charging rate (satisfactory). The charging cable would not engage with charger’s port, replaced cable, no issues. Happy so far, have charged 2 batteries. Will probably misplace the charger before I need it again ;?)

It charged my non-rechargable battery to my key fob.
I really like the design of this charger. I was able to recharge the non-rechargable battery to my key fob.

Nice Charger, Inaccurate Charge Indicator
This is a handy lithium button battery charger that can handle various sizes.I have a button cell tester and see that the charging works. However, the led light is supposed to turn from red to green when a charge is complete. Instead in my situation, the led light maybe turn green briefly, then go back to red. Or it may be red unless I adjust the connection, then it turns red.Also, the picture on Amazon is misleading in that it gives the impression that there are 3 leds that shows the state of charge like 1/3, 2/3, 3/3. But instead the only led that lights up in the middle one.Because of the led not working as described, I give the button cell charger 3 out of 5 stars.

Junk & Very Disappointed
I purchased 2, and both did not work. I used various rechargeable coin batteries, and none of them would charge. I also used a USB test meter to confirm charge, and there was NO (zero) charge going out to any of the coin batteries I inserted..

Works Great. Costs Too Much.
Easy to use. Fully charges button batteries. I paid $10 which is pretty steep for a one-battery charger.
