Review: iMuto 30,000mAh Ultra High Capacity Portable Charger

Portable Charger iMuto 30,000mAh Ultra High Capacity









  • A high enough power capacity that can charge any device multiple time. Can last for weeks.
  • You can charge 3 devices at once.
  • Features a Digital power capacity indicator.


  • It's heavy at a weight of 1.1 pounds.
  • A low Max Output of only 3.4 Amps.

We’ve already we’ve one of iMuto’s 20,000mAh power banks and that proved to be good.

It had all the charging and design aspects that came together to make it a truly quality portable charger.

However, there are many different variations that iMuto has made of their portable chargers and there are even one these 30,000mAh power banks that use USB-C that we still have to do a review on as well.

For now, though, we’re reviewing this iMuto 30,000mAh power bank that 3 charging ports.

It’s boasting quite a lot of features but like always, let’s see what this power bank with a monstrous capacity has to offer with its quality.

Power Capacity:

It has a starting power capacity of 30,000mAh and of course at Charger Harbor, we’re more about what the Output power capacity is because that’s the power capacity that you’ll be using.

With that said, since the iMuto power bank doesn’t use any special batteries like LG or Panasonic ones; also there are the 3 charging ports that you can use, so it’s going to matter just how much of the Output you’re going to be using all at once.

Most of the time, you’re going to be using the fastest charging ports that the power bank has to offer which are 5V/3.1A port and a 5V/2.1A port.

With those 2 being used, you’re going to be averaging at about 25,000mAh of power capacity and we know that’s a lot of power capacity that’s lost during charging but we’re also assuming that by using those 2 ports you’re reaching the max output of 3.4 Amps that the power bank can Output.

So you can most definitely get more Output power capacity depending on the charging speed that your devices are charging at.

What you can you do with the Output power capacity:

It’s with a 25,000mAh power capacity that makes the charging near endless with this power bank. You’ll be able to charge any smartphones multiple times and we mean ANY smartphones.

Even a smartphone like the ASUS ZenFone 3 Zoom with its 5,000mAh power capacity can still charge about 4-5 times to its full power with this power bank.

Charging smaller battery capacity smartphones like iPhones will easily result in 8 or more charging cycles.

This power bank is also perfect for tablets and this goes for both Mini tablets and Full-sized tablets. Mini tablets like the iPad Mini 2 and 4 can charge to full about 2.5 times. Full-sized tablets can charge 2 times to full.

No matter how you look or use it, the iMuto power bank is used for days, weeks, and even a month if you’re using it moderately, without needing a recharge.

Output Charging:    Port 1:  5V/3.1A   |   Port 2:  5V/2.1A  |   Port 3:   5V/1.0A

Even though we’re not fans of having charging ports having their set charging speeds, rather than having charging speeds shared through each port; each of the charging ports and the max output of the power bank is at an acceptable limit.

Port 1:

The first port has the fastest charging speed and is near Quick Charge speeds by being able to Output 5V/3.1A, so this is the universal Go-To USB port if you want to charge your device the fastest.

This is especially true if you want to charge your Quick Charge compatible smartphones near their max charging speeds.

This port will be able to charge tablets at their max charging speeds of 5V/2.4A and standard charging smartphones will be at their limit charging speeds.

Port 2:

The next port is only a single Amp lower than the 5V/3.1A, and it’s still perfect for charging nearly any device that you want to charge at the acceptable charging speed.

Even though it won’t charge tablets or Quick Charge compatible devices at their max charging speeds, it does well enough by providing 2.1 Amps of power.

Port 3:

You’re going to want to avoid the 3rd port at nearly all times since it can only output 5V/1.0A and that’s slow charging speed. The only time that we can understand using this port is when you’re using all 3 charging ports at the same time.

Overall Output charging:

The Max Output of the iMuto power bank is lower than we’d like it to be.

It can only Output 3.4 Amps at once and we find this to be a very lower Output charging speed because you can’t use Port 1 or Port 2 at their full potential at the same time.

At most, you’ll be able to get 1.7 Amps of charging speed if you’re using the first 2 ports at the same time.

Using 3 of the Output charging ports will result in each of the ports only being able to Output 1.1 Amps each.

So using all 3 charging ports at the same time should be done with the understanding that each of the 3 devices you’re charging will be charged at very slow charging speeds. We’re not saying that there’s no winning with this power bank but it’s limiting.

Input Charging: 5V/2.1A

The Max Input charging speed of the power bank is 5V/2.1A and if you’re using a 2.1 Amp wall charger or higher, then it can recharge within 10-11 hours.

We would have liked for the power bank to use similar recharging designs like Poweradd’s or EasyAcc Monstrous power bank by using 2 Input Micro-USB ports and that would be able to cut recharging times in half.

Size and Weight:

It’s not that long of a power bank but don’t let the short length of the power bank fool you into thinking that it’s somehow portable for on-the-go purposes because it’s not.

It has a length of 5.1 inches, a width of 3.1 inches, and a thickness of 1.2 inches. Sure it’s small, but the main thing of the power bank that makes it a large one is the weight being 1.1 pounds.

As a result, holding it isn’t going to be comfortable at all, or at least for an extended amount of time it isn’t.

So most of the time you’re going to want to carry this to your location and to simply set it down for when you’re using it.

Functional Components:

All of the functional parts are in the same general location.

The 3 Output charging ports are on the short side of the power bank, the power bank can be found on the long side, the Micro-USB Input port can be found on the opposite long side and the main attraction is on top of the power bank which is the Digital power capacity indicator.

Charging automatically starts when you connect a device to the power bank.

This leaves the power button with the main function of simply checking the power capacity because the Digital power capacity indicator turns off during charging so it doesn’t burn into the available power capacity.

Also, the use of a percentage way of telling power capacity is easier to understand than just dotted lines that most portable chargers use.

Structure and Material:

Just like its 20,000mAh power capacity version, this iMuto is also made of plastic and doesn’t hold any rugged power bank qualities.

That’s not to say that it isn’t tough. It’s perfectly built for daily use, it’s just that you must be careful of dropping it on hard ground or any ground for that matter.

This is because the weight of the power bank can be its greatest downfall as a lot of shock is produced from the fall.


On the tech side, things could better but then again they could be worse as well. It uses an array of safety tech that is helpful against Surges and Short-Circuits; as well as the ability to control temperature and it keep things regulated even when you’re taking things to the Max Output.

It could have used LG or Panasonic battery cells to offer a better Output power capacity and longevity for the power bank’s quality.


Having an extremely high power capacity already places this iMuto power bank at a very high-reliability level, the 3 charging ports pushes that reliability even further.

It’s with this power bank that you can charge a range of devices multiple times and you can charge 3 at the same time.

With that said, regardless of what it is on the surface when you look at the details, then the main weakness is shown.

The max Output of the only 3.4A can be very limited for those that are not only searching for a power bank that can charge 3 devices at the same time but also fast charging speed.

If you’re charging 3 devices at once, then the charging speed from each port can be highly unreliable.

Even with its Output power capacity being lower than the initial one, this iMuto is power bank is still able to provide lots of charging cycles to any USB charging device.

We’re talking about going weeks without needing a full recharge for this portable charger. The Max Output could use an upgrade because what it’s currently at is very limiting.


It’s small but still very heavy and most of the time you’re going to be setting it down when you’re using it. The use of a Digitial power capacity indicator is very helpful.


Nothing too special about the build quality, but it does make use of good safety tech.


With it having such a high power capacity, that’s what makes it the most reliable. It’s just that the experience of using the large power capacity could be better by improving the Max Output.
