HiLetgo 5pcs TP4057 1A 3.7V Lithium Battery Charging Board with Protection Type-C USB C Li-ion Battery Charging Board Over TP4056

These boards work well. One star off because 1. The chip installed is not a TP4057 (0.5A) but in reality it is a TP4056 (1A) in spite of the marking. If one has the curiosity to download the datasheets for the two chips you'll see that TP4057 is a SOT23 not a SOT8. 2. The supplier had no idea that the board has a protection chip equivalent to XB5352 that offers protection to over discharging. When I asked they said they didn't know,. Bu other than these clones appear to work as the real ones. My configuration was a 18650 battery and a light load

I used one of these in a project for my daughter that runs a strip of LEDs off a rechargeable lithium 18650 battery. This board charges the battery perfectly and is very small, which works great for wearable projects. Just be prepared to solder some very small and tightly packed connection points. I especially appreciate that there are solder points to add an external USB connector so you aren't required to use the USB-C port that's on the board itself To charge the battery.

Works as expected but heat is something I didn't account for in my project. This thing turns really hot, 70C easy. If putting on a 3d printed parts it'll soften PLA and even PETG. I wish it was .5A

Very compact. No issues. I used it to replace/upgrade a broken micro-USB charging port on a wireless speaker.

Good for my project although small warning they do get hot so I suggest you be careful also when soldering wires be very careful and precise you may accidentally remove one of it’s tiny components. I’d say if your project can fit the blue TP4056 ones use them they seem a bit better quality (obviously they’re bigger) also doesn’t saw someone else’s comment on it saying it has a tpb4056 Wich is true but the model for the circuit board is just named a tp4057. Way overpriced for 5 but you know what i got it in time for this project usually I go on ali exp Ali baba or some other Asian website.
