ZMI PowerPack 10K Review

Who wouldn’t want a fast, reliable, and portable power bank that is compatible with almost every single device in the market? In the never-ending search for the best power bank, we’ve stumbled upon the ZMI PowerPack 10K, which at first glance seems like a great option to satisfy that need. This power bank has a 10000mAh capacity, and it is light, portable, fast, highly compatible and so much more. If you’re in the hunt for a power bank, this review will let you know why the ZMI PowerPack 10K stands out from the rest.

Capacity & Charging speed

The ZMI PowerPack 10K has a capacity of 10000mAh, which is certainly not the biggest capacity on the market. From its 10000mAh advertised capacity, you can count with around 7000mAh to power your devices due to the losses as a result of the 3.85V/5V voltage conversion and efficiency. Nevertheless, it’s still powerful enough to give 2 charges, and even 3, to the average smartphone.

It features a single output USB port that provides three charging modes: high-speed (Quick Charge 2.0), normal, and low-power. It does not support USB PD or Quick Charge 3.0, but it’s still highly compatible with iPhones, iPads, Android smartphones and tablets (Samsung, Huawei, LG), and even Bluetooth headphones, Fitbit watches, and small laptops.

The ZMI PowerPack 10K will automatically detect when a device that supports fast charging has been plugged in, so the LED light on the side will immediately turn on. For example, a Samsung Galaxy S8+ supports QC2.0, so it will charge at its highest rate (9V/1.6A, 12V/1.2A) in less time than in normal charging mode (around 1.5 hours).

If you want to switch from fast charging mode to normal charging mode, you need to press the side button once, and the LED light will turn off. This way, you will know that the power bank is ready to function at 1A or 2 A/2.1 A normal charging mode, which is advisable as the QC2.0 protocol wastes more power by operating at higher voltages and currents. All in all, save the fast charging mode when charging in a hurry.

To access the low-power charging mode, you must press the button twice so that the four LEDs flash one by one, forming a continuous loop. Make sure to use this charging mode with low-power devices such as Bluetooth headphones, and Fitbit watches. If you wish to go back to normal power mode, you need to press the button once; using low-power charging mode with your smartphone will definitely increase the charging time significantly.

Contrary to what most people think, the PowerPack 10K does not offer dual input; instead, it offers a USB-C input port and a Micro USB port as versatile and quick charging options to choose from, with both employing Quickcharge 2.0. This means that the power bank has an input of 5.1V/2.4A, 9V/1.6A, 12V/1.2A from either port. However, the charging time will vary depending on which charger you use, being 4.2 hours with a 9V/2A, 12V/1.5A QC 2.0 power adapter, 6.2 hours with a 5V/2A power adapter, or up to 12 hours with a 5V/1A power adapter.

Another distinctive feature is that both input ports support pass-through charging, which means that you can plug in your smartphone while the power bank is recharging from a power outlet. However, you need to choose either the USB-C or the Micro-USB as pass-through can’t be done by the two ports in simultaneous.

Look and feel

Overall, despite not having bonus features like a flashlight or a display, the ZMI PowerPack 10K outshines other power banks of a similar capacity due to its functional, minimal and sophisticated design.

The ZMI PowerPack 10K is a traditional rectangular power bank with slightly rounded edges, but what makes it unique is the anti-slippery coating that ensures an excellent grip and an elegant texture at the same time. It comes in three different colors (black, aqua and white) so that you can choose the one you like the most.

It has a 3 part body (top, bottom, and middle sections) made of plastic of the highest quality. The front panel contains almost all functional components, including the USB-A output port, the USB-C and micro-USB input ports, and the 4-LED white light power indicator. On the right side, there’s the power button, and next to it, there’s an engraved lightning symbol and a single LED blue light that indicates that the power bank is on and working in the quick charge mode. Printed on the left side, you’ll see the technical specifications, and the logo is found on the top, specifically on the right upper corner.

Durability & Construction

The ZMI PowerPack 10K is impressively robust and reliable, given that only premium materials and components are used in its construction.

A well-known fact is that the lighter the power bank, the more resistant to drops is, and unlike other plastic-made power banks, this case is surprisingly resistant so it will not easily chip, crack, or break.  You shouldn’t be too worried about protecting the case thanks to its anti-slippery surface, which not only grants a better grip but also prevents stains, smudges, and scratches. Besides, the power button and ports are solid durable, but as in many other power banks from different brands, the LED indicator starts to fails after some time.

Moreover, the ZMI PowerPack 10K operates with the highest lithium-polymer cells that ensures extended use and efficient energy conversion. It also employs protection for you and your devices against several charging problems, including overheating, short-circuiting, input overvoltage/reverse-polarity, output overvoltage/overcurrent, and battery overcharge/overdischarge.

If your ZMI PowerPack 10K malfunctions, let’s say it overheats, you’ll be covered by ZMI’s 18-month limited warranty, which most likely will replace your defective power bank for a new one. Unfortunately, the warranty does not cover damages caused by accidental drops, liquid spills, and user repairing or alteration.

To extend the battery life of your ZMI PowerPack 10K, it’s advisable to use it until it depletes completely and to avoid leaving it exposed to high temperatures, humid environments, or direct sunlight.


The ZMI PowerPack 10K is a modest size for carrying anywhere, from a run to a camping trip, and even aboard planes given that it measures just 5 inches in length, 2.7 inches in width and 0.5 inches in thickness, and its capacity of 10000 mAh does not exceed the limit allowed by the FAA.

In addition, due to the fact that it is made of plastic, it feels significantly lighter than other power banks of similar capacity like the GETIHU Ultra Slim 10000mAh and the Yoobao 10000mAh. In fact, it weighs just 6.2 ounces, which is less than a pound and almost the same weight as a Samsung Galaxy A10.

For anyone who wants a light and compact power bank, the ZMI PowerPack 10K is an excellent option because it can be held in one hand, or easily slide into a pocket, purse or backpack, without occupying much space.

Final Thoughts

If you’ve been looking for a medium-size power bank to fit your on-the-go lifestyle,  you don’t need to look any further. The ZMI PowerPack 10K could be the smartest choice thanks to its versatile charging modes, great capacity, speed, lightweight design, and wide compatibility. At Power Bank Expert, we highly recommend it!
