I’ve just received 2 boards from Chip_Partner and they have no logo on the TP4056 chip.

I’ve noticed that MP1405 based boards are offered as widely as TP4056.

It says that they have protection built-in. That might be very useful for small DIY projects. Did anyone here test them. Are they as good as TP4056 based boards?

Anyone found a datasheet on this chip? I did some searching and couldn’t find anything.

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.

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!)

Mooooooo

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:

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

Thanks for your inquiry.

The chip in this module is the same with the one in your manual.

It is produced by TP and it is genuine.

If you are interested in this item,you can place an order for it.

Hope we can do a pleasant business with you.

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.

@kaiser: I’ve bought also from “chipworld” some modules because the pictures showed genuine TP4056. What I’ve got are lookalikes with 4056ES/B1443D (Logo is kind of a “C” with a dot in the middle – it looks like this http://china.makepolo.com/product-picture/100278973348_0.html or this http://jimlaurwilliams.org/wordpress/wp-content/uploads/2014/10/Chip2014... but laser-engraved). I’ve started a dispute on eBay and asked the seller to send me items that match the pictures. The answer is for a refund a have to send them back. Did you send back yours for a refund? Is there somewhere more information/tests about this exact clone version 4056ES? It might be even better than the original or much worse…

Antenne, I haven’t sent mine back and the seller didn’t ask for it. But I guess the difference in my case was that I asked before ordering if I get a board with genuine chip and I didn’t. So when I first complained he asked me to just try it and claimed that this board is just as good. But I insisted that I wanted the original chip because it’s well tested and safe to use, whereas this one is of unknown quality. He refunded me after that. I wouldn’t have sent the board back to him even if he asked because that would cost a lot more than the board itself.
Pavithra_uk has done some testing of these boards we got. It’s not as good as original, but usable.

Thank you for your answer. You are right, I’ve read this part (Pavithra_uk’s results in the other thred) too and these are the same boards I’ve got with all the equal markings. Did you used any of them? I think the biggest risk would be if the termination voltage is not accurate enough (>4.2V). For most applications it wouldn’t matter if the charging take a little longer than possible with genuine TP4056.

Antenne, tell the seller it costs more to ship it back to china than its worth. The seller of course is already well aware of that, he is just hoping you will give up and go away.

I haven’t seen anyone chart the charge profile of any clone chips yet. So we don’t even know if they are proper cc/cv.

I wonder if it anyway possible to mod these cheap usb charger boards to adjust the final voltage? my TP4056 10440 charger is only charging to 4,17v and because the small 10440 battery has so little energy to begin with, i would really like to get a charger that charges it to 4,2-4,25v.

I understand it is possible to charge lithium battery to 4,25v but you lose half the possible charge cycles, from 500 to 250, but because these small battery is relatively cheap i would happily exchange some charges for more lumens and longer runtimes, and just replace them when they can’t keep up anymore.

You don’t only lose charge cycles, capacity will be degraded. Your working against yourself by overcharging.

Yes i know capacity will be degraded, that is the nature of the best unfortunately.

And the capacity degrading happen with all lithium battery, for every cycle you get a tiny bit less, i would like to exchange a bit more capacity for a bit more loss of capacity per cycle.

And because i often only discharge them to max 3,3v i think it could possibly even out in the end.

But as i said at least i would like to charge them to 4,2v, so is there any way to fix these boards so the charge to full capacity?

I don’t agree that i work against my self if i would slightly overcharge, i can easily discard a battery that doesn’t fully charge at the expected time anymore, and buy another one.
And until that happen i would gain more output and more runtime, exactly what i want.
