New Miller ML-105 V1.0 & updated ML-202?

*Check post #12 for updates!!

Just saw this new Miller charger in convoy aliexpress store.

There are really no info of this charger here in the forum, I wonder if someone ordered theirs already? I’m a big fan of the Miller chargers and if this one perform as good as the ML-102 V8.0 then it’s worth it! Specs says it can fit from 18650 & 26650 with length of 65-70mm, up to 1.3A charging current and support for 4.5-18v input. There’s no power bank function in this one, however I found a chinese site mentioning a new ML-106 that does.

There is also a new ML-202 which comes with a upgraded chip: SY6952B (same chip in the 105 and 102V8.0 ) vs TP4057 used in the discontinued version. This new chip in Simon’s page shows the ML202 capable of pulling 2A from a 5.0V source to charge 2×18650, and 3.6A when an USB device is connected… assuming that at 3.6A your USB port is still cable to maintain 5.5V like his PSU.

oh nice, hopefully FT gets it soon Big Smile They've had a very successful run with the Miller chargers and I wouldn't be surprised if they get them.

Interesting. I'll wait for the ML-106, being able to use it as a power bank is useful when carried in a backpack.

I’m ordering a ML-202… If it’s really as good as it promises then this is definitely the best power bank/charger combo available. So far none of my power banks are able to match my ML-102 V7 and V8 in terms of efficiency: 125% charge to an iPhone 6 from a Panasonic B.

Also most power banks do not offer correct charging method to the batteries, they jump to CV way too early (some as early as 3.9V) in order to make it “safer”, but this also means a much longer charging time. And some other power bank overcharges the cell to ~4.22V which is worse.

ML105 is just a USB battery charger.
ML106 is the same as 105 with added power bank function, but it’s not released yet.
ML202 is a dual 18650 version with all the functions of above models.

Notice in the 105 there is a rectangular plastic cover, it’s for the USB output port in the 106.

Thank you very much for info! Smile
Will wait for the 106….

Does the ML202 charge individually? So I can use different batteries?

EDIT: It has twin TP4506 on board so – yes you can use different batteries!

The old ML202 has twin TP4506, the new one has SY6952B.

SY6952B is a 4.0-23V input, 2A single-cell synchronous buck Li-Ion battery charger, suitable for portable application. Select pin is convenient for different cell voltage.

Oh I missed that part… I tried to order these some weeks ago but there was a problem with my AE account, I contacted Simon directly to pay him via PP.

Miller ML-202 is here! I got it from Simon convoy aliexpress store.

First look:
-V4.0 marked on the back of the PCB.
-Won’t fit protected cells or even button tops. Only works with flat tops.
-Construction is on par with other miller products (very good). Solid feel with the battery cover on.
-Both channels appear to be independent for both charging and discharging. Left 2 cells with 0.5V difference overnight and remained the same.
-With a battery in place a blue LED will always stay on and turns brighter when a USB device is connected.
-USB output is automatic and very sensitive, even a usb power meter will activate it.
-Fully charged cells measures 4.17v and 4.18v.
-3 LEDs each side: red for charging, green for charge completion and blue for usb outout.

Further testing required:
-USB output can be used while charging but it doesn’t seem like a bypass, applying 1A load only increased 0.1-0.3A to the current draw (1.9A max). But anyways no standard USB port will provide more than that.
-Charging: quick test shows 1 cell draws 1.02A, charging 2 cells draws 1.67A.
-Solar charger compatibility, will it charge across a wide voltage range, 4.2-5.2v? Will report back after testing.

Only works with flat tops:

Compared to a Xiaomi 10,000 power bank:

Appears to be two independent channels, someone more experienced with these components please confirm?

Nothing on the back:

With 1 cell in place it draws 1.0mA when in standby. This is a very low discharge but will still deplete the battery in a couple of months.

With 2 cells in place it draws 0.4mA each side when in standby.

Output with 2 cells:

Removed one cell but output remained steady, no flicker no nothing. Impressive!

Thanks for the news and great info will34.  Looks promising.  Hoping HJK will be provided one of these to do his awesome testing on.

I got mine from the same seller now as will34. Works wonderfully. Much faster charging than my new ENB double powerbank (not the one HJK has tested). Love the separate indicator LEDs for both batteries.

Yes it can be used as a powerbank… 106 has the added Usb output function as compared to the 105.

I mean UPS, i know it can be used as powerbank, but i need it as UPS (Uninterruptible power supply) I have ML 202 on the way, but i need some cheaper UPS just for one router. Thanks Wink

I think i will get the miller ml 202 & the ml 106 then just see which I like better. I want to use it while traveling so my batteries stay charged & my phone as well. Does anyone know if there is a cigarette lighter adapter option to charge while in the car?

It looks like ML-202 V5.0 is out – https://world.taobao.com/item/525035811908.htm

  1. Looks like V4.0
  2. New power management IC: IP5206 (same as ML102-V9.0)
  3. Input voltage is now 5.0-5.3V (I could reliably charge V4.0 from 5-20V!)
  4. Charging current is now at 2×1.5A (V4.0 was 2×1.3A at 5.3V)
  5. New indicator LEDs – 5 green LEDs show charge level
  6. Single slot output only! Second slot is only for charging – you have to swap batteries manually to discharge both!
  7. Auto shut-off in 20 seconds, auto turn on when load is attached. (Maybe less phantom drain?)

If the IC is the same as in ML102-V9.0 then I’d expect that the output would be the same too at 1.4A. V4.0 was 1.25A. Both numbers from HKJ tests.

I doesn’t look much like an upgrade to me :/

I’ve just got one of the ML202 V5.0 with the intention that it would provide a very low power output for a low power device that is low enough most power banks turn off while powering.

VERY disappointed.

So, only flat top bare cells fit; forget using any of your other 18650s.
I need to keep running at 0.014A, even at 0.05A this turns off.
I was getting 7.88Wh out of the PB and wondering why – it only uses the right hand slot for the USB output (when viewed with the positive terminal at the top).
You have to take out both cells and swap them to use the full PB capacity. The only thing about this is that you do know when you really get to 50% remaining capacity!
Even on one cell, it is outputting 2A, so that is quite impressive.

Considering I bought it for the low output current, and as a PB, this is a big fail for me. Not sure what I’ll do with it.
