l own several Xiaomi products, and among them are powerbanks for my children, and so far not one of their products has disappointed me, for they are products of excellent quality.
lt’s great to know Xiaomi is not resting on their laurels, and is even improving. :+1:
This weight seems incorrect. I believe that spec came from some online shop (eg. banggood or gearbest seem to quote that).
The official weight from the Xiaomi website is 330.5grams.
I own one (PLM05ZM) and using a digital weighing scale, the powerbank weighed 328grams.
Using ZKE EBD-USB+ load tester/meter, I did a discharge test (QC3.0 12v @ 1.50A) with the following results, which seem to exactly jive with the one above.
What I don’t understand is the voltage kept on increasing as the powerbank gets discharged and shut down. Voltage was 12.18v initially (1.50A load), but just before it completely got drained, the voltage reached a high of 12.78v (all the above measurements are from the ZKE EBD-USB+ tester software).
400gr was from BG spec, The real measured weight as stated in the OP was 326gr for new and 339gr for old version.
There’s also a very small increase involtage in my unit at 12V but I believe that is normal, such small difference can be nelegible. At 5V, above 1.5A the output voltage steps up 0.2V, this is intentional in order to fight against cable losses. I just realized there is no graph for current ramping, will upload one soon.
Can anyone confirm that QC from Blitzwolf BW-C10 works with that power bank?
I’m asking because QC from BW-C5 I own does not work with that power bank.

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?
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).
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] )
