Slight Issue BUT DEFINATELY RECOMMENDED!
Although one of the connectors had a defective problem, it was quickly replaced. When compared with vast majority similar competitive products, this particular unit is vastly superior from my experience. It is smaller and allows for secure precision mounting ... especially in 3d print configuration. It also has components mounted in from edge allowing for gripping of edges or use in really tight configurations. Itd indicator LED is near enough the connector with the brightness enough that no particular considerations are needed. My future design projects WILL include these modules! DEFINATELY RECOMMENDED!

Small and it works! Anyone who is using 18650 batteries should have this!
When you buy these, make sure you understand how this works. It charges batteries but you can't draw power from the USB-C charging port. There are other small charging boards that can do both! Just search here at Amazon.

Great little charger board. Solid red light means charging!
Soldered wire to magnets, making sure to put magnets on larger magnets first to maintain magnetism (heat will destroy/mix it up). Worked fine.One important thing to know, the lights. A solid red means you're charging.

Voltage lower than advertised
I got these chargers for my 18650 3.7V batteries. The no load charging voltage is 4.02 instead of the 4.20 voltage advertised. I could not find any instructions on these, and has terminals labeled "+" "B-" "Out" . I tried both B- and Out and did not find any difference. There is a green power light that stays on all the time, and a red charging light. I had the charger on my 18650 battery for 2 days and the charging light never went off, and the battery reached a max voltage of 4.02 volts. I got the same results from both charger boards.I don't know how these tiny boards can be mounted without caking them up with hot glue. It would be nice if they were a bit larger with mounting holes for screws.

Not 4.2V
The other guy is correct and in my case 'no load voltage' is only 3.9V. I tried to charge 190 mAh 3.7V and it just never went to full charge after hours of charging.

Use 1 Ahm charger only.
Such a great mini 3.7v litiun charger, although it heats up a little when using 1.5 Ahm charger, but they work great. Thank you and recommended.
