Review: Lumina 15,000mAh Compact Portable Charger

Lumina 15,000mAh Ultra Compact Portable Charger









  • A Capacity that can last for days
  • Max Output is 4.8A and each of the Charging ports is able to deliver 2.4 Amps that can charge most devices at max speed
  • There is no Power Button, so the power bank is more usage free and no button functions


  • It's large and heavy
  • If you're at or near the max charging speed that the power bank has to offer, then the power capacity will suffer


There are a few power banks that you should know about.

They may not be the most popular but some portable chargers deserve attention because they offer something that not too many other chargers offer, while still meeting other expectations that make them great.

It’s these kinds of power banks that are going to most likely grow more popular as they start small and go big in the future as they become more recognized as exceeding standards.

This the Lumina 15,000mAh power bank that has a few things that set it apart from other portable chargers, and other charging tech companies should take a few notes about why this charger can do very well as time goes on.

Power Capacity

The power capacity of the Lumina is initially 15,000mAh, however, this capacity can change quite a bit depending on how you’re using the charger.

It has two charging ports, so if a single port is being used then you can expect a power capacity of about 13,000mAh and if you’re using the 2 charging ports, then you’ll be getting about 11,000mAh of power capacity.

This is because the more devices you charge and the faster they charge, the more power that’s lost during charging because of heat generation. It’s all about the current that’s being released from the power bank and the efficiency of the charger to deal with it.

With an average power capacity of 12,000mAh, you can still expect to use the power bank generously. It’s ideal to charge smartphones with this power bank because it can charge many smartphones 4 times or more.

It’s even more perfect to use smartphones because of two charging ports, so you can charge 2 smartphones to their full capacities at the same time.

This 2-port portable charger is also very useful for charging tablets with its capacity. This is especially true if you’re charging lower capacity tablets like the iPad Mini 2 or 4 since they can charge to full, 2 times; Although, that’s only true if you’re using the entirety of the power capacity on a single device.

Overall, the lowered power capacity during charging isn’t severe and you can still use it for days without it needing to be recharged.

Charging Power that Rivals Top Brands

The charging speed of the Lumina power bank is really good. It has the same charging speed that other power banks take advantage of like the PowerCore 20100.

So in this case, the two charging ports can deliver a max standard charging speed of 5V/2.4A and what’s even better is that the Max Output is 4.8A. You’ll always be getting a standard max charging speed no matter what device you connect to it and it doesn’t matter if you connect 2 devices to the power bank.

This charging speed is great for smartphones because nearly all smartphones will be able to charge at their fastest speed (Except for Quick Charge compatible ones, since this power bank does not feature Quick Charge).

The 2.4 Amp charging is even better for tablets like iPads because the max charging speed for iPads is 2.4A. You can charge 2 iPads with this power bank at the same time, and their max speeds.

We’re really glad to see such a new power bank charger enter the arena with full Output charging capabilities; and honestly, other portable charges should make an effort to reach this kind of Output delivery.

Input Charging: 5V/2.0A

The recharging speed of the Lumina is very standard at a simple 2 Amps. However, we would have liked to have seen a 2.4 Amp recharge speed instead.

With that said, it’s still okay and as long as you use a 2 Amp wall charger to recharge it, you can expect a full recharge within 6-7 hours.


Size & Weight


The design of the Lumina isn’t all that bad on its size but it could better. The length of the power bank is 6.7 inches long, 4.1 inches in width and 0.6 inches in thickness.

So it’s quite large and we think that the size is more of a 20,000mAh power bank’s size rather than a 15,000mAh. It also weighs quite heavy at 1 pound.

Okay, so it’s not designed very well in the size and weight department but it’s perfectly manageable with its body structure being smooth and straightforward. You probably won’t be using this in your hand along with using your smartphones since it’s somewhat heavy.

Although, the one thing that comes as a surprise is that you can fit this charger into a back pocket. That’s right, the 0.6-inch thickness can fit into a big enough back pocket. We know it sounds silly but hey if you can fit a large capacity power bank into a pocket, that’s pretty cool.

Functional Components

Onto the functional components parts. All of the functional components are on a single side with a LED power capacity percentage display, the 2 Output charging ports, and the Micro-USB Input all being on a single side panel. And if you noticed, there is no power button on this power bank.

This is because the charger can automatically begin charging once a device is connected to the USB charging ports and to check the display on the LED display, you simply shake the power bank and the display shows how much power capacity is left on the power bank.

This is what we’re talking about when we say this Lumina offers something just a little different; there’s no power button and yet the power bank is still able to function properly.

This kind of design is very logical since all the power button would be used for is to check the power capacity, but now you can simply shake the charger and it will appear.

A Better way to tell Power Capacity

The LCD power display is something that needs to become more common among power banks because a numeric value is easier to read and gives a more pinpoint power capacity reading.

Structure and Material

The build isn’t anything special with it having an Aluminum Alloy center body and the two side panels are made of plastic. The structure of the power bank is overall a strong one and at this point, if a power bank can’t hold its structure with its repeated uses, then it’s simply not worth getting.


On the inside, Lumina hasn’t mentioned anything on safety tech but they do have certifications like the FCC and CE, so we can assume that there is indeed some sort of safety tech measures that have been put into place to make sure the power bank doesn’t damage itself or your devices.

It doesn’t use Panasonic battery cells and that’s a shame because the use of such batteries would put the Output capacity in a higher range.


It’s a reliable charger if you’re searching for a power bank with just a high enough power capacity that can last for a few days. Its charging speed is good with it being able to Output 4.8A. So each of the ports can deliver a max standard charging speed of 2.4A.

The design could use some work with its large size and heavyweight at 1 pound.

We’re guessing that it has something to do with its Aluminum body and by using plastic, the power bank could very well be lighter.

With that said, the portability isn’t too much of a problem since you can always just set it down and charge your devices or you can even fit it into a large back pocket if you’re on the go.

Lumina has built a reliable portable charger that has its few faults but with its new design like the lack of a power button and the integration of a LED power display, we think it’s headed in the right direction.

iMuto 20,000mAh Power Bank



The power capacity is, of course, lower than the initial power capacity but it’s going to depend on the way you use it to know what Output capacity you’ll be receiving.

However, you can expect to get about 12,000mAh on average. The Output charging is one of the strongest points with it being able to Max Output 4.8 Amps and 2.4A through each of its ports.

As a result, you can expect many smartphones to charge at their max speed and tablets will be able to charge at their max speeds as well.


The size and weight could use some work since the Lumina is pretty large and heavy. All the functional components are on a single side and there’s no power button.

So to check the power capacity, you can shake the power bank (Really odd), and charging begins once you connect a device to the power bank. once all devices are unplugged from the power bank, it turns off automatically.

There’s a LED power capacity display and a numeric display is much better than a LED dot display like many other chargers have.


The physical structure build is alright with the centerpiece being Aluminum Ally and the two side panels are made of plastic. There isn’t any mention of safety tech but the certifications it has can be considered to be safety tech confirmations.


It’s a reliable charger, and this is universal. No matter what you’re charging, it’s able to provide an optimum charging experience with its power capacity and speed. It’s hard to say for the long-term though without the specifications of safety tech.
