Compatible with a huge range of fast charge protocols
PPS support (hard to find)
Incredible value for money
Very poor performance at the 45W max output
USB-C PD and Quick Charge cannot be used at the same time
If you’re finding a 20,000 mAh power bank with high battery capacity and maximum output, and is capable of charging across various devices and fast-charge protocols, the Xiaomi Mi Power Bank 3 Pro is perfect for you. Its compatibility with various fast-charge protocols, plus the pack’s high performance on various charging loads are very impressive. While it fell short on higher voltages that are required on power-hungry devices like bigger laptops, this power bank still has a lot to offer in terms of fast-charging your device with great results. That’s why the Xiaomi Mi Power Bank 3 Pro is worth your money.
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. For one, this power bank has a capacity of 20,000 mAh or 74 watt-hours, and a maximum output of 45W. This pack also features a USB-C PD port which maxes out at 45W, and a USB-A Quick Charge port which maxes out at 18W. With these features, this pack suits with a wide range of devices because of its compatibility with various fast-charge protocols such as Power Delivery 3.0, Quick Charge 3.0, and Programmable Power Supply (PPS); as well as brand-specific protocols like Samsung’s Adaptive Fast Charging (AFC), Huawei’s Fast Charging Protocol (FCP), and Apple 2.4A. However, this power bank is a rare find in some countries like the United States. 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. If you’re thinking about buying one right now, go for it! Although, if you’re still not convinced, you might want to read through this article because Power Up will provide you with reasons why the Xiaomi Power Bank 3 Pro is definitely a good run for your money.
Length: 153 mm Width: 73.6 mm Height: 27.7 mm Volume: 0.3121 cubic meters The Xiaomi Mi Power Bank 3 Pro (PLM07ZM), at first glance, looks slightly bigger than every other 20000 mAh pack because of its volume of 0.3121 cubic meters. Weighing about 428.6 grams, this product is also heavier than the other packs of similar capacity. 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. There’s nothing really special about the design – maybe apart from the embossed “Mi” logo that can also be seen on Xiaomi’s Mi phones – but still, it’s a step up from the Standard hard plastic casing that is usually present on many power banks in the market. For its charging features, the pack has two USB-A output ports and a USB-C input/output port at one of the shorter ends of the pack. We will discuss more on the capability of these ports below. The package also contains a short USB-C to A cable which measures 30.48 cm. long, and a user guide. Sadly, this doesn’t have a USB-C to C cable with built-in E-Marker chip for Samsung phones that require PPS such as Samsung Galaxy S8 to S10e, Note 8/9/10/10+, and S20/20+/20 Ultra phones, among others. 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. Thus, you will need to purchase and/or use a cable that suits your device.
Looking at the manufacturer details, the Xiaomi Mi Power Bank 3 Pro has a rated capacity of 20,000 mAh or 74-watt hours, which is a bit higher than similar 20,000 mAh packs such as the ZMI QB820 and the Anker PowerCore Speed. This pack boasts a high total output of 45W which can be consumed at maximum using the USB-C port. What’s interesting with this port and output is that it can be used to fast-charge a wide range of devices because of its compatibility with fast-charge protocols such as Power Delivery 3.0 which are present in newer iPhones (8, 8 Plus, and later models), and iPads (Pro, Air, Mini) among others; Quick Charge 3.0 (Xiaomi Mi 5 to 8 SE, Xiaomi Mi Max to Mi Max 3, Nokia 6-9, etc.), and Programmable Power Supply or PPS (Samsung S20/S20+/20 Ultra, Xiaomi Mi 8/9, etc.). The Xiaomi Mi Power Bank 3 Pro’s USB-C PD port also supports brand-specific fast-charge protocols such as Samsung’s Adaptive Fast Charging (Samsung S6-S10e, Note 8/9/10/10+, etc.), Huawei’s Fast Charging Protocols (Huawei Honor 7, Huawei Nova 3, etc.), and Apple 2.4A, Apple’s fast-charging protocol before integrating the PD, which are still being used by most iPhones and iPads. Outside smartphones, the pack’s USB-C port can also charge the likes of Nintendo Switches and laptops. However, as per the latter, you may need to read the testing part of this article because charging laptops with this power bank has its limits. 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. However, not like the USB-C port, the USB-A ports can only support Quick Charge 3.0, Samsung’s Adaptive Fast Charging, Huawei FCP, and Apple 2.4A. So what about the more obscure fast-charging mode such as VOOC/DASH/WARP that are being used in phones such as Oppo F11, OnePlus 7/8, and Realme 3 Pro/5 Pro/X? Well, these are not supported by the Xiaomi Mi Power Bank 3 Pro. If your phone requires the more obscure charging modes, you might want to look for other power banks that are compatible with your device. Another thing to consider is the power bank’s capability to fast-charge multiple devices. Unfortunately, you can’t use both the USB-C PD and the USB-A Quick Charge feature of the pack at the same time to fast charge devices.
XIAOMI Mi POWER BANK 3 PRO CAPACITY AND PERFORMANCE (TESTED)
So now, we test the performance of the Xiaomi Mi Power Bank 3 Pro under various charging loads. Here at Power Up, we monitor the performance of the power bank as we increase the demand on it. Considering that the pack has a higher rated capacity (20000 mAh or 74-watt hours) and higher maximum total output (45W), we will step-up the procedure by subjecting this pack to much higher charging loads. 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%. Despite calling it a baseline load, the pack’s high output and efficiency at 5W are pretty impressive. This pack can be able to charge smartphone devices at anything above a 90% efficiency with great results. 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. Thus, you can use the full potential of the pack by charging your smartphone multiple times. 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%. Again, the pack proves its amazing power as we set it in a much higher output, resulting in an efficiency that is still higher than the industry standard. High efficiency at 18W is also perfect for fast-charging your iPhone, or even Nintendo Switches. Then, we test the performance of the pack by subjecting it to a 30W load, or at a 15V/2A output:
So, at a 30W output, the Xiaomi Mi Power Bank 3 Pro performs at 63.52 watt-hours or an 85.58% efficiency. Again, for a high output load, this is still considered as a high-efficiency which means that the pack is still performing well. Thus, we can prove that the power bank can be able to charge the likes of the iPad and other mid-sized devices.
Finally, we set the charging load to the pack’s maximum output: 45W or 20V/2.5A. Will the power bank still be able to perform well? 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. Honestly, this decrease is something to be expected from power banks of this capacity. You can be able to charge laptops with at least 30W to charge such as Macbook Air with this pack. However, for bigger laptops that need 65W charge, using this pack will possibly give you horrible efficiency as there will be quick depletion of the battery pack. This might make 10,000 mAh power banks more useful and efficient for some people.
SHOULD YOU BUY THE XIAOMI Mi POWER BANK 3 PRO?
If you’re searching for a power bank that can fast-charge Android phones, iPhones, iPads, Nintendo Switches, and even small laptops such as MacBook Air, then the Xiaomi Mi Power Bank 3 Pro is perfect for you. Price-wise, it actually depends on where you can avail the product because it can be very hard to find. 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. Just look at its amazing 45W output and its capability to fast-charge devices using various fast-charge protocols. However, this pack doesn’t allow users to charge using both PD and Quick Charge, and it provides horrible efficiency to power-hungry devices such as bigger laptops. However, if you want a power bank that will charge a wide array of smartphones and mid-sized devices, the Xiaomi Mi Power Bank 3 Pro is the real deal. asdf
