Review: MyCharge HubMini Power Bank

MyCharge HubMini Power Bank











  • Has a Very Small Size
  • Two Built-in Cables of Micro-USB and Lightning
  • 2.4A Input Recharging


  • Very low power capcaity

Power banks that have built-in charging cables are among the most useful type of power banks.

This is because you’ll always have a portable power source that you’ll be able to use at all time because there’s a cable or rather some power banks have multiple built-in cables that are ready to charge your devices.

With that said, these kinds of portable chargers usually have high enough power capacities that are able to charge devices multiple times over; but in some cases, it makes sense for these chargers to also have lower power capacities.

This is because a lower power capacity will mean that it’ll be able to have a smaller size and if you still have a built-in cable with a power bank that makes the experience better.

In this case, that’s what this MyCharge HubMini power bank is. It has quite a low power capacity which makes it small and it also has a built-in cable.

Power Capacity:

The MyCharge HubMini has a small power capacity of 3,000mAh and during charging it goes through standard conversion rate; as the max charging speed of the power bank is 5V/2.1A.

3.7 x 3,000 = 11,100 / 5 = 2,220mAh

So you’re receiving about 70% of the 3,000mAh initial power capacity and that’s not too bad in this case with a mini power bank.

It’s with an Output power capacity of 2,220mAh that you’re actually able to use that you’re going to be able to charge most smartphones to their full power.

However, with newer smartphones that most likely won’t be the case, as they have larger batteries. For the most part, newer smartphones are going to be able to charge near their full power.

If you plan on charging higher capacity devices like tablets with this power bank, it’s not the best idea as most tablets like iPads will only be able to charge either half way or a maybe even a quarter to their full power.

Output Charging:

The MyCharge HubMini has 2 built-in cables. One cable is Micro-USB for Android devices and the other cable is a Lightning cable for charging iPhone and iPads.

Overall, the charging speed of the power bank is quite good, because both of the cables share the 5V/2.1A Max Output of the power bank.

So if you’re charging a smartphone using only single cable, then that smartphone will charge quickly because the power bank will be putting forth the full 2.1A charging power to that cable.

If 2 devices are charging at once, then each cable will most likely be outputting 5V/1.0A charging speed because the Max Output of power will be split.

Input Charging:

The power bank is recharged through a Micro-USB Input port and surprisingly the max recharge rate of the HubMini is 5V/2.4A. So if you’re recharging using a 2.4A USB wall charger then the power bank will be fully charged within just 1-2 hours.

Size and Weight:

Along with its low power capacity, the HubMini is indeed a Mini power bank that doesn’t leave any questions about its portability.

This is because it has a length of 3.5 inches, a width of 1.4 inches and a thickness of just 0.9 inches. So it’s a small enough power bank that it can fit into your pocket or you can just hold it in your hand while your charge your smartphone.

Another reason for its awesome portability is because of its very lightweight at just 3.5 ounces.

Functional Components:

Almost all of the functional parts of the power bank are on a single side. That’s where you’ll find the Micro-USB and Lightning built-in cables that are about 3 inches long.

Above the cables is a power button and 4 White LED power capacity indicators. Lastly, the Micro-USB port used to recharge the power bank is at the bottom.

Charging does not start automatically, so the power button must be pressed for charging to start.

Structure and Material:

The outer shell portion of the power bank that’s silver is made of Aluminum and the inner part that’s dark is made of plastic. It’s a very well built power bank that can take a few light falls but just don’t go treating it like a Rugged power bank. It’s also best not to tug on the cables.


On the tech side, the HubMini uses safety tech to keep you and your devices safe during charging.


The purpose of a portable charger is to be portable. That’s the reason they were made in the first place because we’re now able to charge our device wherever we are and no longer have to always be tied down by USB wall chargers.

With that said, there can always be improvements and this MyCharge HubMini is what an improvement looks like, even if it’s a small one.

That’s because it has a small power capacity, which results in a small size and it has built-in cables that are always ready to charge. So as long as this power bank has power, you’re able to take advantage of it.
