(Last Updated On: February 26, 2021)


High-capacity portable chargers sit on the spectrum of power banks that many people use, and many people don’t use.

They’re able to deliver a massive amount of power, but the free portability is mostly lost because high-capacity power banks tend to be a lot bigger and weigh more.

Even so, these monstrous portable chargers are still great to use if you’re looking for a charging experience that’s going to last a long time without needing a recharge for quite a while. Additionally, these kinds of chargers feature charging tech that lower capacity power banks don’t have.

In this review, we’re reviewing Aukey’s 30,000mAh power bank. It’s got quite a lot of things going on, so let’s get started!

Power Capacity:

As you probably already know, the power bank’s capacity is 30,000mAh, and that is a LOT of power. However, here at Charger Harbor, we’re here to reveal the truth about what power banks offer.

In this case, though, there’s not much to uncover, the Aukey 30,000mAh portable charger has a real capacity of about 27,000mAh, and that’s still quite a lot of power to charge plenty of devices a few times over.

The capacity loss is contributed to the charging that this charger offers, which is three ways, but we’ll get to that later.

Power Capacity for Smartphones and Tablets

You can expect a lot of charges for smartphones. iPhones are likely going to receive the most charges because of their low battery capacities. Even for larger capacity smartphones like the Galaxy S7 Edge, you can expect to get about 7 full charges with this portable charger.

Tablets will be able to charge plenty of times as well because an iPad Mini 4 can charge fully 5 times over.

This type of power bank has a power capacity that can last for days and is perfect for camping, road trips, having it in case of an emergency, or simply using it every day because of its amazing power capacity. Power anxiety will be wiped away as you charge your device again and again.

The power bank has many charging options that can fit quite a lot of charging ways. There are two USB ports. One of the USB ports is Oranged colored because it has Quick Charge 3.0 and the other USB port is simply a regular AiPower port.

The Quick Charge USB port can charge Quick Charge 2.0 and 3.0 at their Quick Charge speeds.

Output Charging:

Quick Charge 3.0 Port Charging Speeds: 3.6V-6.5V/3A, 6.5V-9V/2A, 9V-12V/1.5A

Charging stats for the Samsung Galaxy S8 from the Quick Charge port

The above are the speeds for the Quick Charge port. So if you’re using a Quick Charge compatible device, then you’re going to be getting 3 Amp charging speeds, which is some high-speed charging.

However, if you’re not using a compatible device with the Quick Charge port, then the charging speed will either go down to 2A or 1.5A for the device that’s connected to the port.

It’s not all that bad, though, because even though there’s a decrease in Amperage speed, the Quick Charge port provides high Voltage, and as a result, the Amperage that you’re getting with non-compatible Quick Charge devices will stay more constant.

AiPower Port Charging Speed: 5V/2.4A

The Green port on the power bank is Aukey’s AiPower port, and this means that it provides a max charging speed of 2.4 Amps. This is the max standard charging speed and will charge any devices connected to it quite quickly.

2.4A is the max charging speed for tablets like an iPad, and so you can expect smartphones and other USB charging devices to charge at their fastest rates when they’re connected to this port.

Next with the charging capabilities of this power bank are the input ports. Or least one of them is hybrid, with the USB Type-C port acting as an Input and an Output port.

USB Type-C Output Port: 5V/3.0A

The Type-C Input port can also be used as an Output port and be used to charge devices that are compatible with the Type-C charging cable. This means that you’re going to need a Type-C to Type-C charging cable so the Type-C port can act as an Output port.

When you’re able to use this port as an output, it can charge at 5V/3.0A, and although you’re receiving 3 Amps current charge, the port has quite a low voltage.

Not only can you charge smartphones that are compatible with the Type-C cable like the HTC 10 and Nexus 6P, but you can also use this charging port to charge Newer Macbooks since some Macbooks use a Type-C Input to charge.

So there you have it, this high-capacity power bank cannot only provide plenty of charges to smartphones and tablets, but it can also provide charging to a laptop! How cool is that?

Input Charging (Recharging):

USB Type-C Input Port: 5V/2.0A

Micro-USB Input Port: 5V/2.0A

On the other side of charging, this power bank’s recharge can happen through two Input charging ports simultaneously. Each of them can recharge the power bank at 5V/2.0A charging speeds, but if you’re using both of the ports to recharge the power bank, the max recharge speed will be 5V/4.0A.

If you’re only using a single Input to recharge the high-capacity power bank, then you expect a full charge in about 13 hours. If you’re using two Input ports, then the recharge time is cut down to about 7 hours to full capacity.

The individual recharge speeds for each of the Input ports are different when you’re using this individually. Meaning that the USB-C port used as an input port has a max recharge rate of 5V/3.0A, and the Micro-USB Input port has a max recharge speed of 5V/2.4A.

Weight and Size

Of course, when it comes to having such a large capacity and providing so many powering options, this power bank is large. But it’s still compact. The length is 5.9 inches, the width is 3.3 inches, and the thickness is 1.1 inches. So overall, it’s not physically large.

Sure the power bank is pretty big compared to other portable chargers, but those are usually lower capacity power banks. The 30,000mAh power bank can still be held in one hand if you wanted to hold it in your hand, but that’s most likely not going to happen.

This is because the portable charger’s dimensions aren’t the main problem; it’s the weight. This charger weighs 20.4 ounces. That’s 1 pound and 4 ounces heavy. Most power banks are much lighter than this but going along with what it’s capable of; this charger is heavy. Even though it can fit into your hand, it won’t feel comfortable because of how heavy it is.

Best used as a Charging HUB to take on-the-go

Because of the weight being so overbearing, you’re going to have to opt for using it as a charging hub. This charger is not meant for your Pokemon GO adventures, but it is meant for travels that take you where you still need power.

Taking it to the office is a great example of perhaps using it in the library because you can charge your MacBook, smartphone, and tablet all the same time. This is what I mean by that this is a beast of a charger. It’s portable in the way that you’re supposed to take it to a location and use it. Not so much for on-the-go purposes.

Functional Components

The functional components on the high-capacity power bank are clear to see and easy to use.

All the charging Output and Input ports are on a single side of the charger. The Two USB Ports are next to each, and the USB Type-C Input/Output and Micro-USB Input are next to each other. Between the two USB ports is an LED flashlight that can be turned on via the power button.

Holding the power button down for 2-3 seconds, the LED flashlight turns on, and holding it like so will turn off the power bank.

The power button has two other functions as well. The power button must be pressed to turn on the power bank so it can begin charging the device that’s connected to it.

This charger does NOT automatically detect and begin charging. Another thing is that the power button is the power capacity display. It displays the power capacity in three colors.

White: 70-100%

Green: 30-70%

Red: 0-30%

Structure and Material

Large capacity power banks tend to have poor build because everything is everywhere, but this isn’t the case. Instead, the Aukey 30,000mAh power bank’s structure does a great job of being as compact and well built as possible.

The charger is made of plastic and has few separate pieces to make the charger whole. Even so, the power bank does a great job at being built solidly by holding a strong binding with its separated structures.

All the functional components of the power bank function perfectly and provide a straightforward user experience.


On the inside, the charger is supported by some safety tech like Over-Charging Protection, Over-Current Protection, and Overheating.

However, the overheating one is a bit questionable because the charger does heat up a lot. The heat generation is mostly caused by the charging speeds that the charger is capable of Outputting. If you’re using all the charging outputs on this power bank, then you can expect it to become quite heated up.

The heat can result in less capacity being transferred, and it will also damage the battery capacity in the long-term.

Structurally the power bank is built very well, but at times, the charger can be too powerful for its good.

Its power capacity alone makes the charger very reliable. The power can last for days or even weeks, depending on how you use the charger. While relying on the power bank’s high capacity, you’re also able to take advantage of the faster-charging options.

With Quick Charge, AiPower, and USB Type-C port. The ways to charge your devices provide the optimal charging experience.

You may not be able to walk with this high-capacity power bank comfortably, but for any other cases, it’s perfect to rely on.

The charger can easily be used as a 3 port charging hub for charging 3 devices simultaneously. You can potentially charge a MacBook, your smartphone, and tablet all at the same time. This doesn’t pose too much of a problem for the charger because of its insanely high capacity.

Easy to use. It has lots to offer.

A power capacity of about 27,000mAh can charge many smartphones more than 6 times over. Some Tablets will have no problem charging 4 times over. The power capacity can last for days, depending on how you use it. The charging options that you get with this power bank are phenomenal.

Two USB charging ports; one is Quick Charge 3.0 and the other being Aipower. Then, the Type-C port can be used as an Output port and charge compatible devices that use Type-C. You can use the Type-C port to charge a Macbook.

The Type-C port can also be used as an Input alongside the Micro-USB Input port, and putting them together can create a max recharge speed of 4 Amps. This can recharge the power bank in about 7 hours.


It’s a very normal-sized power bank that can be held in one hand and placed in a bag quite easily. However, that’s not what stands out the most. Instead, the most notable thing is that the power bank is quite heavy, weighing at 1.4 pounds.

It’s a portable charger that’s portable by taking it to a location and using it. It’s not meant to be held and used. All the functional components are in the same area and are very easy to use.

The power button is an integral part of the charging experience, although an auto starts charging feature would have been nice to have.


The build of the portable charger is done well. The charger is made of plastic with a few separate pieces stuck together to make the charger whole. As a whole, the physical structure of the power bank is strong. On the inside, the power bank features safety tech to prevent any damage from happening to your device.

With that said, the charging options can make the power bank generate plenty of heat, and because of that, the power bank’s capacity that the user receives is depleted. It’s questionable how this power bank will perform over the long-term because heat tends to degrade batteries.


It’s a very reliable portable charger because of its capacity and charging options. The portable charger may not be as portable as other chargers, but it’s simple to know that it’s equivalent exchange. The power bank has plenty in power, but it has to give up versatile portability.

Even so, the power bank can be taken nearly anywhere and be used at a location for the best user experience. Best of all, you can charge 3 devices at once.

This high capacity is the first and foremost thing that will be the most intriguing aspect of this power bank. The power capacity can last for days or even weeks, so you’re always with power.

The charging options provide fast charging no matter which port you’re using, and the recharge speed of this power bank matches the power capacity with two Input ports to charge from simultaneously.

It’s not the most portable power bank (Obviously), but it does well when taken to a location and used. The main flaw with its design is simply the weight. If it were lighter, the charger could even better than it currently is.
