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.
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.
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.
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!
No charge control IC. So it would not be CC/CV.
I’m afraid this is not a good charger guys.
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
