Touch wood I have used before giving these away with flashlights and not had any problems with half a dozen off them. I have another two on order. The only problem you may have are that they only charge at 650 ma. All off them have terminated at 4.18 to 4.2 volts. I still would not recommend not keeping an eye on the charge though. Good luck with the builds.

Wow that saved me some $$ I was thinking on buying 5 of the 4sevens chargers

I ordered the charger from Intl Outdoor a week ago.  I didn't notice the low charge rate.  I wanted it because it'd give me a second 26650 charger that would get me started on the path to 32650's.

 

The TR-005 has a much better charge rate, but mine over charges my batteries by ~0.02V.  It doesn't fit my protected 26650's very well, and sometimes I'll tape down the battery to improve its contact.

 

I haven't read many good things about the TR-006, which is too bad because it looks very desirable.

The low mode should be lower.

This is my only charger, it is a no nonsense simple device, light turns red when charging, flickers between red and green when almost full, and goes solid green when charging is completed.
Mine terminates at 4.15V, it was 4.19V the first time i used it, but after a few uses it now always terminates at 4.15V. So use it a few times before giving it away to determine its termination point.

Is this a cc/cv li-ion charger?

Has anyone opened this charger and find out what chip it is using?

I have know Idea. I do know that all the ones I've had just work.

It has to be, voltage only wouldn’t charge it fully, and it stops charging once the green light comes on.

I have such a charger ripped open laying around…I can make a photo. Ordere from cnq for about 3$
I use only the cradle with my hobby charger, there were much things in it but on the first view I recognized no common charger IC.

That would be interesting to see Werner. Smile

Can you see any marks on the chip that might identify the chips used in the circuit?

Xtar SP 2, can charge with up to 2A, with a charger than can charge with less 1A it will take almost for ever to charge a 26650.

Thank you for the pictures of internal of HG-106LIX. I wonder why the manufacturer chose to use 5 transistors instead of 1 IC for that charger? It was probably more economical for them to use the transistors than IC. Those pictures are so clear and sharp. Great pictures!

Thanks Werner for the pictures! Beer
No charge control IC. So it would not be CC/CV.

I’m afraid this is not a good charger guys. Sad

Gut it & add one or two tp4056 usb charger boards inside. $1 on ebay (ebay search). 850mA charge current each, CC/CV chip (won’t overcharge, trickle charge after it shows done or change in termination voltage). HKJ tp4056 review.

It could also make a nice adjustable charging cradle for any other charger like Werner has done.

Flickering leds is a big sign it has no CC/CV charger IC.
Termination voltage that has ever changed like that is bad.

Review on IO also reports that it continues to trickle charge after light goes green.

Mine seems to do CV/CC, i’ve done some experimenting on it, when the LED is flickering it reads 4.14V on the battery, when it goes solid green its at 4.15V (laptop pull this takes 2-3 hours, ing kong about 1 hour, i can’t explain why the timing difference), and i’ve left it on green overnight, and if its trickle charging its very very slow, it was still at 4.15V. This charger never goes above 4.15V which is nice for longer cell life, but i want a 4.2V charger so i can fully charge a battery for the rare times when i do want longer usage

Its inconsistent. Which is to be expected for something like this.
One trickle charges, yours doesn’t seem to.
Yours started out with a 4.19v termination voltage, now 4.15v. Do you really want to still be using it if it decides to change again?
King kong charged in 1 hour would take 4 amps. Something is not right there. Have you tried to measure the charge current?

This thing has no charge controller chip. Charger chips are available quite inexpensively. You leave it out when your looking to manufacture it extremely cheap. Inconsistency comes from parts with poor tolerances. Parts may even be used near or above their limits. Manufactured extremely cheap just doesn’t go together with AC power & sold direct from china. If you teardown its AC transformer there is a good chance you’ll find it does not have proper separation.

I understand when anyone buys an item they want it to be good, they have invested in it. And this is sold by intl-outdoor who until now has seemed to carry good quality items.

I’ll open it up if i can and post some pics
my ml-102 charger did the same thing, first time 4.15V now 4.11V every time, and i check batteries about 75% of the time coming off both chargers and both are within 0.1V of their second time use (4.15V and 4.11V respectively)

I meant from the flickering stage to solid green

Right click and view image to see full size

You will be happy to know i broke a wire from the circuit board to the negative terminal and have no iron to resolder it so it can no longer charge anything

No, I’m not happy it broke. I presume you have no other charger that fits your king kong.

I’m trying to inform fellow members that this is a poor charger & could even be hazardous. I have no intent to be mean. Apologies if you felt I was trying to give you a hard time in any way.

If the wire broke at the point its soldered to circuit board you can reattach it by wrapping around the middle pin of the Q5 transistor. “Q5” is marked in white silkscreen on the brown side of the pcb (not on the transistor itself). Tape around the other two transistor pins (between them & the middle pin) to prevent shorts.
Q5 is the leftmost component in this pic.

Another option to still be able to charge your 26650, 32650 would be a $1.49 D cell battery holder. You can wire it to a dummy battery to insert into another charger. No soldering iron needed to make it.

Just need a cheap plastic pen & two bolts with nuts from a hardware store. Pull the point off the barrel of your pen. Get bolts with heads too large to drop completely into the barrel of your pen. The bolt’s threaded shaft should fit in tho. Wrap each wire from the battery holder around a bolt & tighten the nut down onto the wire. Wrap tape, paper or cereal box cardboard around the bolts threaded shaft until it fits snug in the pen barrel. Cut barrel down so its 65mm with the bolts in.

So why did this charger work so well if its not designed properly?
It broke at the metal piece that attaches to the negative terminal, i also can’t figure out how to put it back together, i shouldn’t have taken it apart tired, i can’t remember how it was pieced together

Nothing you’ve said shows it works well at all.
There are any number of ways to get to 4.15v. Some are dangerous.
Again, there are safety requirements for AC powered devices. Cheap devices sold direct from china don’t like to follow them.

It will appear to work fine. Until it doesn’t. Or you look closer.

What do you mean, it charges batteries to 4.14V, takes a while to charge to 4.15V (CV/CC i’m guessing) and terminates with no increase in cell voltage 12 hours later

i agree that the chinese will skimp on safety to make more money, so do first world companies if htey can get away with it, that why safety standards had to be invented, we just have no way to force chinese companies to follow them
