This is typical of Motorola phones when QC is offered over USB-C. Samsung Galaxy, LG, and other QC supporting Android phones would be expected to fast charge. The power transfer is more efficient and lithium batteries endure less heat.
In the first phase, the current (amps) is constant, with a gradual increase in voltage. In the second phase, the voltage (now at a higher state) is constant, with a gradual decrease in current. If your phone was released in 2018 or later you can check its specs to see if PPS is supported. If your devices don’t support PPS this tech will not affect the power bank’s performance.
And with this model, you’ll be future-proofed for a future PPS device. USB Power Delivery is an open-source charging method.
Created alongside USB-C, it is with specs even though it also increases the voltage. The big difference is USB PD uses communication lines to negotiate power transfer.
While proprietary methods take over the data lines for their negotiation. They do so because legacy USB connections, such as USB-A, don’t have comm lines.
But when plugging into a wall charger or power bank there is no data transfer anyway. And pulling out a charger several years from now with a new device could have a bad result.
If you’re a stickler for meeting USB-C specifications this isn’t a good charger for you. This portable charger supports pass-through charging under these connections:
Xiaomi Mi Power Bank 3 vs ZMI PowerPack 20000 The Xiaomi is partly responsible for my favorite power bank, the ZMI PowerPack 20000.
When the Mi Power Bank 3 was announced it looked like an updated version of the ZMI PowerPack 20000. Quick Charge 3.0, Samsung AFC, Huawei FCP, and Apple 2.4A ZMI costs $10 more, but Xiaomi loses that savings when you buy a separate USB-C cable Xiaomi is available on Banggood in China, but ships worldwide If you like the USB hub function (one less USB-C adapter to carry around) then go with the ZMI. If the shipping time isn’t a factor the Xiaomi is more future proof with Power Delivery 3.0 and PPS support.
The Xiaomi Mi Power Bank 3 offers as many fast charging standards as possible in one package. Those outside the USA with fewer options can also enjoy international shipping. Newer phones that support PPS will enjoy a more efficient charge. And put less wear on the power bank and their device’s battery.
The Nintendo Switch provides several full recharges without any downtime. You could play the most demanding games for a full day in handheld mode.
Or power a Nintendo Switch dock in a remote location for a bit less time. And most 13-inch/14-inch laptops can stay topped off while performing normal workloads.
Almost every significant fast charging standard is on this power bank.
Xiaomi has U.S. based support (web, chat, email, phone). They are a large and well respected Chinese electronics company, most known in the USA for their smartphones and laptops. They helped found ZMI, their USA mobile power brand.
Banggood is a Chinese e-commerce retailer that focuses on gadgets and electronics. They ship worldwide, with warehouses in Australia, Europe, Hong Kong, and the United States.
Banggood’s reps are aware of how Chinese retailers are viewed. They have recommended using PayPal over a credit card for the added security and want customers to understand the longer ship times before they order.
It’ll support a wide range of diverse brands and devices. Need a single power bank that’ll meet almost any charging need
Xiaomi Mi Power Bank 3 Pro
The Xiaomi Mi Power Bank 3 Pro (PLM07ZM) is the kind of pack that offers great charging capacity across various devices such as Android phones, iPhones, mid-sized devices like Nintendo Switches and iPads, and even lightweight laptops. You can find one on lesser known e-commerce sites like China-based Banggood where it costs $50, or if you’re lucky, you can be able to buy one at physical stores. Talking about its surface and casing, this rectangular power bank has a rubberized matte black finish which has a nice feel when you hold it in your hand, and two metal caps at the shorter ends of the pack. This also doesn’t have a USB-C to Lightning cable that suits for newer iPhones (8, 8 Plus, and later models), and iPads (Pro, Air, Mini), among others. This pack boasts a high total output of 45W which can be consumed at maximum using the USB-C port. Outside smartphones, the pack’s USB-C port can also charge the likes of Nintendo Switches and laptops. In addition, the Xiaomi Mi Power Bank 3 Pro also utilizes Quick Charge 3.0 on its dual USB-A ports that amounts to 18 W at maximum. First up, let’s check the efficiency and performance of the Xiaomi Mi Power Bank 3 Pro under a baseline of 5W, or 5V/1A of output: At a 5W charging load, the Xiaomi Mi Power Bank 3 Pro is capable of discharging at 71.27 watt-hours, which is equivalent to an efficiency of 96%.
It is also worth noting that in continuous use at a slow charging rate of 5W, a fully-charged pack can be fully discharged for 14 hours and 32 minutes, which is a long time. Now, we jump to the 18W or the 9V/2A output: After testing, we found out that the Xiaomi Mi Power Bank 3 Pro is capable of discharging at 67.79 watt-hours, or an efficiency of 91.61%. After testing at 45W, we have found out that the Xiaomi Mi Power Bank 3 Pro has significantly dropped its performance — getting just 47.8 watt-hours, or of a 64% efficiency. Upon researching this, you can get the actual pack via China-based e-commerce site Banggood for $50 which is already an incredible value, purchasing this is definitely worth it.

Xiaomi will launch its new Mi Power Bank 3 Ultra Compact in Europe
A tech blog claims to have heard from an exclusive source that Xiaomi will launch its latest power bank in Europe. This apparently 10,000mAh Mi Power Bank 3 Ultra Compact is also slated to have a new, texturized casing that might prevent drops or damage to the new product. As the name suggests, this Mi Power Bank 3 Ultra Compact is rated for 10,000mAh in capacity (or 5,500mAh of effective charge) only in order to support a new form-factor that might fit into a pocket with greater ease.
Xiaomi Mi Powerbank 3 Pro Review – 45W Power Delivery, 20,000mAh
The original Xiaomi Mi Powerbank 20,000mAh used 6x LG F1L 18650 cells and had a decent efficiency rating. Mine worked great for almost 2 years and when the status leds failed, I took the batteries out to re-use them.
After this I lost some trust to pouch cells but decided to give the new Xiaomi’s offering a try anyways. This unit was not a free review sample , I bought it from Aliexpress for $43 shipped which is a lot more than the retail in Asia, but even at this price its pretty on par with what similar product costs on amazon. Just like any other xiaomi powerbanks, very simple packaging with just a short USB 2.0 A to C cable and a chinese instruction manual. The familiar design is carried on just like before but this time with a matte finish coating all around and shiny polished plastic on both ends.
It doesn’t show on the product pictures, but it is a lot larger than the older model. Side button used to restart the unit and trigger low power mode.
When the USB-A output is on and you connect or disconnect a charger on the USB C port, it will reset and restart in about 1.5s. Note that PD 20V is rated at 2A instead of 2.25A for the full 45W output, but this doesn’t matter as much because most devices chose to use 15V3A or 20V2A anyways when 20V3A isn’t supported.
Compared to the old version it does not have automatic voltage boost above 1.5A draw which acted as cable resistance compensation. Based on the testing on the Mi Powerbank 2 I expect the new version to perform on par when it comes to output efficiency, but the factory rating is already very conservative at 85% @ 25W and that is in ideal conditions.
45W PD Adapter: when using the powerbank at high current draw such as 20V 2A, the LVP will kick in before the battery is entirely drained. In those cases when recharging back up it will require less energy because there is still charge left. The output is very stable and consistent, even with the axis range zoomed in it remains pretty flat. For low power devices such as smartphones the efficiency is good and I’d recommend using the USB-A as much as possible.
But for power hungry devices maxing out the PD output means wasting a lot of capacity, at 47Wh output it barely provides a full charge for my Surface Pro 6 which has a tiny battery compared to full size laptops (up to 99Wh). -Recharging time is impressively quick using a 45W PD adapter, it’s the fastest I’ve tested so far for a 20,000mAh powerbank.
-The matte and polished plastic finish is not the most durable, but this doesn’t affect the performance. Now the USB-A puts out exactly 5.0V which means some devices won’t be charging at optimal speed, they should’ve gone with 5.3V output instead. There are many things that were left out due to my limited time and because my YZXStudio ZL1100 broke, I used a much more powerful discharger for these tests but it’s fully manual.
Review: Xiaomi 20000mAh Mi Power Bank 3 Pro – Tech Jio
It seems that any USB-C charging capability will hold the “Pro” moniker, with the 10,000mAh Mi Power Bank Pro being the first power bank to support USB-C charging. Finally, the 20,000mAh version was released by Xiaomi, and it is called the 20,000mAh Mi Power Bank 3 Pro. Unlike the previous generations where they were all white in color with a stubbled grain finish, the new 20,000mAh Mi Power Bank 3 Pro rocks a matte black color with a smooth finish.
The upper and lower parts of the power bank have a shiny gloss finish, which leaves fingerprint marks very easily.
And using both USB-A ports at the same time will provide a 5V/3A output, which is suitable for fast charging of smartphones supporting Qualcomm QC. This means that the power bank is able to charge USB-C laptops such as the MacBook Pro.
The USB-C port also supports Power Delivery (PD) so you will be able to fast charge PD-compatible smartphones and even other devices such as Nintendo Switch and mirrorless cameras. And this was done while I was surfing the net on Google Chrome, to simulate real-life user experience.
At a maximum output 45W, it is good enough to charge most devices and beats the competition out there from Anker and RAVPower.
Xiaomi Power Bank 3 Pro (45W PD) Review
One of my biggest beefs with quite a few high-capacity power banks is the time it takes to charge them up, so this was the first thing I checked. When using a QC 3.0 charger that supports up to 20V/2A, the power bank pulls 12V 1.5A (18W). I used the usual Samsung 9V/1.67A adapter that is shipped with all their phones. When using a source that supports 5/9/12/15/18/20V at 3A, the power bank pulled 15V 3A (45W).
When using a Pixel Charger (5V 3A or 9V 2A), the power bank pulled 9V 2A (18W). The two main protocols – Qualcomm Quick Charge and USB-PD are supported. Charge is supported at speeds up to 45W, which is great for filling up the 74Wh capacity quickly. Samsung Wireless Charger Duo charges using AFC 12V
All the other fast charging protocols (QC, AFC, FCP) are supported over the USB-C port too. Thankfully it doesn’t try to use the 20V 2A profile which is lower power.
However, no matter how hard I tried with how I plugged it in / changing whether the power bank was on or off before I plugged it in, I was unable to make my phone charge the power bank. When I tried to “Charge connected device” in my phone’s settings, I was unable to override this and the power bank continued charging my phone.
I assume this means the Unconstrained Power bit is set correctly. You can find it on heaps of other websites though (make sure you get the PRO version though. Supports almost all FC protocols for legacy USB-A devices.
