Xiaomi Mi 2 Powerbank 20,000mAh Review - New 20Ah King?

Thanks for the review! Seems to have an excellent capacity for its weight. Currently $25.99 at Gearbest with coupon code PBANUK1.
I’m still looking for a good QC3 charging adapter with two outputs and low weight. From what I see on Amazon, most of the adapters seem to be poor quality, making noise, delivering QC current only sometimes, breaking…

This Xiaomi PLM05ZM (20000mAh v2) has one of the most number of supported protocols:

Do you mean USB wall charger with 2 QC3 ports? I believe Anker’s PowerPort Speed has 63-watt (5-port desktop charger, with 2 QC3.0 ports) and 39-watt (2-port wall charger, both ports QC3.0 capable) versions, including a PowerDrive Speed 39-watt car charger with 2x QC3.0 ports.

Yes, a wall charger. I cannot find the 2-port PowerPort Speed with EU plug and it seems a bit heavy (130g?). My current 3-port charger (RAVPower, not QC) has a weight of 85g. The new one should not be much heavier.

Edit: I found the Blitzwolf BW-S6 on Banggood, 2-port (1 QC), ~100g, also tested on lygte-info.dk and seems to be safe. Does anyone use this one?

What's that meter you're using there?

It is charging Moto Z Play Turbo mode - 3A 5V. Tested by myself.

I watched some videos on Youtube and there it looks like QC is disabled for output but working for input?

Based on my quick testing, when passthrough charging is used, QC output is disabled, but QC input can still work (ie. the powerbank is being charged at 12v, whereas the device that’s connected to the powerbank can only be charged at 5v).

Ah, so that was you :D

Did you see me? :wink:
But good to know that pass-through charging and QC on the input work at the same time.

While browsing around, I notice another new model from Xiaomi — Mi Powerbank 20000mAh 2C PLM06ZM:

http://www.xiaomitoday.com/xiaomi-mi-powerbank-2c-20-000mah-review-almost-lower-price-tag/

It is supposed to be a lower-priced alternative to the 2nd-gen PLM05ZM (Mi 20000mAh 2). The PLM05ZM was released (in China) for RMB (CNY) 149, whereas the PLM06ZM is RMB (CNY) 129.

But from above review, the lower-cost also means it seems to be a slight step back:

- weight has increased (v1 = 338 grams ; v2= 330.5 grams ; v2C = 358 grams) - the heaviest of the lot (but still a good deal lighter than many 20000mAh powerbanks from other brands (usually 420-460 grams if using Li-Ion instead of Li-Po)

- the length is also slightly longer (probably why it weighs more)

- the same QC 3.0 output (only 1 port can be QC3.0 ; if both ports in use, then both ports can only manage 5v simultaneously)

- no mention of whether pass-through charging will support QC3 input+output (but likely not)

  • uses Fitipower FP6601Q chipset (the BlitzWolf BW-S9 uses a FitiPower FP6600Q chipset, so likely similar protocols supported)

- QC3 input is now only 9v/2A ; the v2 PLM05ZM can have 9v/2A or 12v/1.5A input (but probably just similar charging speed) [in my test I got 12v/1.6A charging rate sometimes for my PLM05ZM]

- I notice GearBest is selling this at $29, which is still higher than prices for PLM05ZM (as mentioned, the PLM06ZM is supposed to be cheaper than the PLM05ZM, maybe as it becomes more common)
(ie. assuming powerbanks can be shipped to your country; so far I haven’t found any foreign seller that allows shipping of powerbanks to my location - Philippines, not even from AliExpress [which appears to be able to ship 18650 batteries to the PHL via Turkey Post/Belgian Post] )

Yeah, ever since I signed up for that Youtube Black thing I get notifications whenever someone watches my vids

anyone has any news about newest xiaomi 20000mah (a.k.a xiaomi 20000mah 2c), as far as i know, it’s bigger, nothing more

and quite cheaper, maybe gonna be new budget king

Actually literally two post above yours ;)

Does anyone know a simply way to force these to run at 12v all the time? Is there a wire you can bridge in the USB cable?

LOL, my bad
Thank you

QuickCharge requires a timing-dependent handshake to activate the higher voltage/power modes, which is probably a good thing, considering that 9 or 12v could be bad for a normal USB device expecting 5v.

Simply way to force QC 12V ist to use a QC Trigger.

More USB wall chargers and powerbanks with USB QC are named here:

Looks interesting , could probably also be used to limit the voltage to 5V and disable QC on the output for higher efficiency (74.4 vs. 68.4 Wh according to the table above) when time is not critical, e.g. charging the phone outdoors overnight. But it’s an extra device to carry around and adds weight. Does anyone have a better idea? My phone has no such option, at least I couldn’t find it.
