HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions

Worked great for my 1650 battery based project

I'm no longer using this but it worked flawlessly as advertised.

Seems to work well, have a 4 battery pack in parallel and voltage is good, charging is working. Not sure what the current draw is on the USB but I'm assuming 1amp as it's connected to a PC USB 2.0. Eventually connecting to 5 watt solar panel

Worked as expected. Use this as the power charging input to my mobile device. Would have been nice to have a mounting hole. This device will be subject to some abuse from the user as they plug and unplug the charging chord. As is I had to design a custom case to capture the module and hold it in place. It performs all the necessary tasks to support my 3.7v battery. I plan to continue using this device

You have to use a USB-A to USB-C charger, or these will not charge. It's kind of frustrating to find that out by reading other reviews.

I used these to fab up stable chargers to balance the cells in my Milwaukee M18 batteries. Worked perfectly!

These work perfectly to charge my 18650 batteries from a 5v solar panel. I have run it for a month with no issues. I am charging 3 18650 batteries in parallel. No problem.

I really like the charger but the board size should be a little larger so the mounting holes could be bigger. Not even my 2mm standoffs fit thru the holes so I will make a custom slotted holder from wood or Plastic. I put together a battery charger with an INA219 board that monitors charge current and voltage and displays on a screen. I have a raspberrypi zero monitoring it and sends an alert when things are done or if things exceed set tolerances. I plan to add temperature sensing to it for unattended charging so I can do things elsewhere at home. The next step is to add a discharge circuit for a full battery charge and testing platform. Of the 3 devices in my order, one failed (no LED's on at ANY time) but the device seems to continue to charge. I am leery of the devices now. You can see the comparison in the photo, one behaves as expected with no battery attached, the blue LED is on and the RED LED flashes. The other appears to be dead but still charges a battery, actually it will OVERcharge if allowed to. Follow up: on the device that had the LED's fail I was able to charge a battery with it even tho the LEDs did not work. BUT, and this is a BIG BUT, the TP4056 was allowing the battery to overcharge, so not only had the LED's failed but the overvoltage/overcharge protection was also bad. I find this unsafe so am dropping my review from 4 starts to 1 star. Update #2: Another of these failed and was over-charging my battery, no LED' indications for any state of the battery. Only one of 3 seems to be working.

Tried this module to charge LIR2477 and also 1s LiPo battery separately. All works well and I like the USB C port which is common nowadays.

Excellent works great, good quality.
