Review / Measurement: Charger module with TP4056 controller

Can someone positively identify the 6 solder points on this board so I dont stuff it up. Thanks.

-/+ on the USB side = extra inputs

OUT-/OUT+ are the leads connected to the load

B-/B+ are the leads going to the battery (thru the protection circuit IC)

Thanks. I dont understand what the out + and - is if B + and - go to the battery.

charger out directly connected to B+ & B-
out- & out+ is via protection circuit. purpose is over discharge protection.

USBPort~~TP4056>Battery outprotection circuit~~>Load(OUT)

Thanks again.

Ordered one of these today:

Only now I’ve noticed that there are two BAT- connections. What for? Also, R and G connections are for external LEDs, right? And what is the EN connection for?

Hello,
I need to know where i can buy the TP4056 as chip only.
I want to integrate it on one of my boards.
I do not need the full populate pcb as it is too big
Any link to buy outside of China ?
I am actually in Canada.
Ebay sellers do not need to apply, due to the facts that they are more expensive than the full assembled PCB.
I bought the full PCB for 0.9USD

I haven’t seen this type of board before, I like the idea of integrating charging and protection in the same board! does someone know what kind of protection does it have? over discharge only? or it also has over current protection? if so, how many amps? (I assume It doesn’t have overcharge, being a charger supposed to stop by itself, but if it has also a separate controller for protection with overcharge too, this is a great find!)

I have used this board for a while, i found it when checking out some test/reviews on youtube on tp4056 boards

I might have some ideas. How many are you looking to buy?

On second though, I don’t have any bright ideas. I took a quick look at ebay and in the US, you can get them shipped for $0.50USD/chip in lots of 5, or$0.15USD/each for 100. Yeah, they ship from china, but that’s the source.

?

I doubt it. I just got 5 I ordered from Banggood that were pictured with the TP-logoed IC. What I got was this:

(click to zoom)

well I ordered from ebay, got 4 fake ones with “Topower” letters in spite of asking the seller in advance if it is a genuine chip and providing image.

Now I asked few more sellers on ebay to provide pictures… wonder what will come out of that.

I hope it is even possible to find some honest ebay or other free shipping sellers of these

I believe it’s the equivalent protection IC’s that are round and on the bottom of 18650’s (more or less) example possibly 2A output (I believe for more they use more chips)
I would like to know if reverse polarity protection built in with the protection IC or if you put them in backwards will it smoke the protection IC as well

Datasheet for the 8205A IC

so, out of 6 enquiries This one is the most promising answer, for this item:

From my experience such answers don’t necessarily mean that it is true. I also made a lot of enquiries to sellers that advertised boards with original chips. I asked if the board is 100% the same like in listing photo, including chip logo etc. Most of them answered that the board is exactly the same. So I chose one seller that had a 99.8 % feedback score, decent amount of sales and specialized in electronic components. But the board I received from him not only had cloned chip, but was of different design too. At least he shipped by Singapore Post so it was quick and he refunded me too. After that I again made similar enquiries to sellers advertising boards with original chips. But this time I’ve added that if the chip is not an original one as in their photo I ask for full refund. Some didn’t answer, some wrote that they can’t guarantee that chip is original because they don’t see the boards themselves and sell what they get from their suppliers. And only one, if I recall correctly, wrote that his board is 100% the same. But once again this is not necessarily true.

this one also said they have genuine chip:
