The TOMO charger has being tested before . You please rest assured the quality . So .I seems i post a wrong place ?Should i post it on “commercial seller’s forum”?

————————————
May i know who is HKJ ? Big guy here ?

Do you still sell 18650 batteries in retail?

He runs this site.

http://lygte-info.dk/

He's the most capable person here for testing batteries, battery boxes and chargers.

You can message him through this forum.

this charger looks interesting too. it seems to measure the battery charge in mAh.
can you give us a discount on this charger?

Thanks very much for your reply. Yes . I knew HKJ . he also have an account on CPF. Welcome Mr.HKJ comment my charger

Same here. I’ll wait until HKJ does a full review on it. If it has his blessing, then I’d buy it.

This looks good and has many nice functions. If it performs as good as it looks, then it is a winner.

Does it use a CC/CV charge process?

Minos, didnt you apologise recently for commercial posting outside the rules?

Edit: Yes, you did. And it looks like 4 threads were unpublished as a result.

Yes . I know . I think i should remove my thread to
Commercial Sellers’ Spot

Should I delete the threat ?

Just move it. Edit your first post and you'll see an option to move the thread.

Thanks very much , I think now is in a right place .

Yep, it's in the right place now.

If you buy in bulk quantities. I will consider.

In order to have your 18650 power bank reviewed by HKJ you would need to contact him & offer to send him one.

FWIW, here’s my experience:

Last month, I bought one of these from BIC (I know, not the most reliable) because it looked promising, but to be honest, I haven’t been that impressed with it. It’s fine and usable, but not what I was hoping for.

As far as I can tell, the 4 channels are independent when charging but drain evenly when discharging (unlike my fake ENBs that I also got from BIC). I might have gotten a dud, but on mine, the channels don’t terminate at the same voltage when charging. They terminate at 4.22v, 4.22v, 4.16v, and 4.15v. On discharge the cells ended at about 3.2v after a little bit of rest.

Another let down was that the 2.1a output was not truly higher output according to my test. I can’t say for certain because when I have my “charger doctor” hooked up, the power bank doesn’t recognize a significant draw on the other end and automatically shuts off after a few seconds. But what I can say is that for those few seconds when I plugged in my ipad mini, it only showed the same 1a on both ports as opposed to the 1.4a I can get from other power banks with 2.1a outputs.

On the positive side, besides the basic auto on, auto off, and auto cutoff, it does recharge four cells at a higher total draw (according to my charger doctor) than 1a, thereby reducing recharging time. It was drawing about 1.6a total at the beginning of a recharge cycle when the cells were nearly empty. The backlit display is kinda cool but honestly not really any more useful than the usual generic row of leds.

I’m not trying to detract from the seller or give a negative review for his product. For all I know I could have gotten a factory reject… I just thought I would share my experience so far with my TOMO power bank. Please take this with a grain of salt as I am not equipped to do a thorough technical review. If I hadn’t already gotten one, I would also be waiting to see what HKJ has to say first. Maybe Minos has a better batch…? Regardless, I am still very curious to see if my results are consistent or if I got a lemon…

Thanks for your info. I think i can only show you guys this video from one of my user

As noted here, I’m seeing similar behavior WRT undercharging on the two rightmost cell positions and also with lower-than-expected currents to iPad devices.
