ZMI PowerBank Mini 3000mAh Review: The Same Xiaomi Portable LED Flashlight

Recently, Xiaomi announced a portable LED flashlight in a lipstick-size. It is capable of charging a small-size mobile device as well, though this not its main purpose. In some sense, we can say the manufacturer has removed the torch and came in with another interesting product via one of its sub-brands. The ZMI PowerBank Mini is another lipstick-shaped product that carries a 3000mAh capacity battery inside. So it won’t occupy more space but will be at your elbow when your phone’s battery drainages the whole power.

ZMI PowerBank Mini

Generally, Xiaomi is the number 1 powerbank maker in the world. At least, it got this title in 2016. The company has designed a few new models in 2017 as well. So we tend to think it will the first in 2017 when the results are announced. As for now, it has released the second-gen powerbanks including the Xiaomi Mi PowerBank 2 and Xiaomi Mi PowerBank 2C. These are the main players in the niche, and we are not even talking about their various capacities and upgrades.

ZMI is known for a few good powerbanks as well. So the ZMI PowerBank Mini that also carries a model number of PB30 should provide a great performance besides a stylish look.

ZMI PowerBank Mini Performance

The tests held on the ZMI PowerBank Mini showed its output power is 1A, while the load voltage is close to 5V. Thus the information on the packaging as this product comes with a standard Lithium-ion 3000mAh battery (supplied by LG) is true, and it supports output power of 5V/1A (5W). Unfortunately, it doesn’t support fast charge.

Anyway, we continued increasing the load, so the output voltage began rapidly reducing and enabling the explosion protection mode. The response speed is very fast.
