GTIWUNG 6Pcs 18650 Battery Holder Case with Lead Wire Bundle, 3.7V DIY Battery Storage Boxes Case Single Slot + 10Pcs TC4056 Type-C USB-C Input Interface USB 5V 1A Charger Module

perfect for the needs i have, used inside 3d printed lithopane lights so could power them on by usb cable and if power goes out they work via battery. absolute must buy and will be buying more for other 3d printing projects

Excellent quality boards for various projects. Charge via USB cable or from a decent solar panel that provides a good current, a simple but very effective way to charge 18650 battery's.

Nice cheap regulator boards that work well. Would be better still with higher output current capacity. Minus one star for the holders because 1. They grip the cell too tightly so the -ve spring is unable to push the positive terminal into the +ve contact properly 2. They are awkward to insert and remove, 3. No room for a temperature sensor and 4 You only get 6 of them, you will need to buy more anyway so why not go for better quality holders in the first place

These are ideal for charging ESP projects. I used one to power a home made soil moisture sensor and charged it using a small solar panel.

Really useful to use in electronics- there are numerous projects on the internet where a 3.7 battery is needed and these holders are perfect for the job

Great chargers

I thought they didn't work initially, but they only charge the 18650 with a USB A to C cable - doesn't work with a USB C PD charger. Just to confirm, you solder the red wire from the battery holder to the B+ pad on the board and the black wire to B-. Connect to a USB A socket and the red LED indicates charging. Nice cheap way to charge single 18650 cells e.g. for flashlights.

This module is not USB C compatible. It will not operate with a laptop or fast charger with Power Delivery (PD) it only ok with a USB A charger and A to C lead or lowpower "dumb" charger wth a USB plug. This module also runs very hot. This is because it is set to maximum current (1A) and is only a small PCB. Changing R3 (between pin 2 and 0V) from 1.2K to 1.8k will reduce th current to 667mA and reduce the temperture of the modue. Charging will take longer of course but's kinder to your battery. Also note that the voltage protecton circuit switches the negative so if you connect the input 0V and output 0V (or cell 0V and output 0V) together you will disable this protection.
