There’s a certain sect of Mini power banks that have higher power capacities than the norm. Most power banks that are very small are the ones that have capacities within the 3,000mAh range, however, there are newer ones that have higher power capacities than that and that means that they have more usefulness. It also means that the power bank is going to be larger, but portability is almost always as easy.

This is the UNU Superpak 5,000mAh power bank that’s in the Mini size range of portable chargers, but this one is able to charge some smartphone a little bit more than just a single time. Let’s take a closer look to see if this power bank has any more upgrades along with its power capacity.

Power Capacity:

The power capacity of this UNU power banks starts at 5,000mAh and the conversion rate is going to be quite good because it only uses a single USB port to charge that has a charging speed of 5V/2.1A. The charging speed is fast and most of the time the power capacity is going to go through average conversion rate; even if you’re using the full 2.1 Amps of power to charge your device, it’s not such a fast speed that would make conversion of power bad.

3.7 x 5,000 = 18,500 / 5 = 3,700

Most of the time you’re going to be able to use 3,700mAh of Output power capacity and this is a really good Output of power. Sure, there can be more power but this UNU power bank is on the higher end power capacity level of Mini power banks and what that means is that this charger is able to charge most smartphones to their full power. When it comes to power banks that have 3,000mAh, the result is that they don’t have enough power to charge all smartphones to full power.

In this case, though, a 3,700mAh power capacity can charge an iPhone SE or an iPhone 7 to their full power. Then higher capacity smartphones such as a Galaxy S8 with its 3,000mAh capacity or a Google Pixel XL with a 3,450mAh capacity can charge to their full power once also. That is one of the main reasons that this UNU Superpak power bank has a good power capacity; which is because it’s able to charge low and high capacity smartphones to their full power at least one time.

Output Charging:

The charging speed is on par with the type of power bank this is and that would be a 2.1A charging speed. A 2.1 Amp speed is able to charge most smartphones and tablets near or even at their max charging speeds. With that said, it’s important to know that this power bank does not feature Quick Charge so Quick Charge compatible devices will not be able to charge at their max charging speeds.

A 5V/2.1A speed is a very good speed when it comes to the higher end of Mini power banks and your smartphone will be able to charge faster than with a Mini power bank that has a 1 Amp charging speed.

Input Charging:

The recharging speed of this power bank is the same as the Output which is 5V/2.1A. In order to recharge the power bank to its full power as fast as possible, you must use a 2.1 Amp USB wall charger or higher; by doing so, the Superpak power bank can charge to its full power within 3.5 hours.

Size and Weight:

It’s a very small and lightweight power bank. One of the greatest reasons that 5,000mAh power banks are growing so rapidly is because they have higher power capacities and yet they still have their small form factors and lightweights.

This UNU Superpak power bank is 3.7 inches in length, it has a width of 1.6 inches, and the thickness of the charger is 0.8 inches. The weight of the charger is 4.5 ounces. Overall, it can fit into a pocket or you can just hold it in a single hand while you charge your smartphone.

Functional Components:

It’s an easy to use power bank because nearly all of the functional parts of the power bank are on a single side.

On the short side is where you’ll find: the USB Output port, Micro-USB Input, a LED flashlight and a power button. On top of the power bank is where there are 4 white LED power capacity indicators. You must press the power button to begin charging and you can double tap the power button to turn on the flashlight.

Charging automatically stops when your device is fully charged or when there is nothing connected to the power bank.


Structure and Material:

The power bank has an Aluminum Alloy structure and it makes it resistant to withstand damage in the event of a fall. With that said, this isn’t a Rugged power bank so you should be careful if you were to drop this charger from a high height.


On the tech side, the power bank does have the necessary safety protections to keep you and your devices safe during charging.


Reliability of this power bank is just as good as other power banks with its power capacity. The reason for that is because it’s a capacity that is able to charge nearly all devices within the Mini segment to their full power. No matter what smartphone you have, you’re going to be able to charge it to its full power with this power bank.

There’s also the charging speeds which are within the 2 Amp range and so your devices are going to be able to charge faster too.

The power capacity of 5,000mAh does have a low Output power capacity, but even so, you’re able to charge your smartphone to its full power and at a charging speed that is quite fast as well. It doesn’t feature Quick Charge though, so those that own Quick Charge compatible devices will not be receiving a max recharging speed.


This UNU power bank is very small and light so you’re able to take it anywhere. Another thing is that most of its functional parts are on just a single side.


Build quality is really good with the casing of the charger being made of Aluminum Alloy.


For the most part, this Superpak portable charger is a great power bank to take with you while you’re on-the-go because it has lots of power and a size that can be taken anywhere.

Specs of the UNU Superpak 5,000mAh Power Bank:

It won’t provide a max charging speed for those with Quick Charge or Type-C compatible devices, but this power bank does provide an optimum charging experience when it comes to standard charging.
