iMuto 20,000mAh Compact Portable Charger
Portable chargers with high capacities are traditionally long and large.
They evoke a sense of having a high capacity through their size because the usual case is that the bigger the power bank, the higher the capacity.
It’s with these kinds of chargers, that are we able to really let loose and charge our devices away from a mere wall charger.

Power Capacity
The power capacity of the iMuto power bank is 20,000mAh and you can expect a pretty close Output capacity near the same since the charging speed isn’t that fast.
With that said, if you’re charging a single device, you’ll be getting about 18,000mAh and if 2 devices are being charged at once, then you can expect a power capacity of 16,000mAh.
So you can still expect plenty of power capacity even when the power decreases during charging.
With an average high power capacity of 16,500mAh, you can do a lot with it.
Like charging most smartphones about 5 times or more. Tablets are going to charge fully but fewer times with tablets like the iPad Mini 2 and 4; but they’re going to manage about 1.5 charges because the charging speed of tablets is faster and as a result, more power capacity is lost.

Output Charging: Port 1 – 5V/2.1A Port 2 – 5V/1.0A Max Output – 3.1A
Charging speed of the iMuto 20,000mAh power bank isn’t the best but it’s still pretty good.
One of the ports can output 5V/2.1A which is near the max charging rate of 2.4A and the other port delivers a rather slow charge at 5V/1.0A. Ultimately, both of the ports can output 2.1A, but only one at a time; and the max output is 3.1A.
So connecting a tablet to this power bank would give it the priority to charge near its max speed and if a smartphone is connected, then it would receive about 1 Amp charging speed.
The output of this power bank isn’t bad at all, but it could be better with a max output of 4.8A and that would then allow 2 tablets to charge at their max speeds.
For now, though, charging 2 smartphones; or 1 tablet and a smartphone won’t pose any charging speed complications.
Charging 2 tablets at the same time may lower their charging speed to 1.5A each with the max output being 3.1A though.
Input Charging: 5V/2.0A
We wish that recharge speeds of 20,000mAh power banks would be faster than 2 Amps but that’s not the case here.
The iMuto has a max Input recharge speed of 2 Amps, so you’re going to have to use a 2 Amp wall charger if you want it to charge that fast.
If you’re recharging it at 2 Amps, then a full recharge will take about 12-13 hours. Anything lower than 2 Amps, like a 1 Amp wall charger, and it’s going to take a full 24 hours to recharge it.

Design
Size and Weight
The iMuto takes a little bit of a different path when it comes to its design because most high capacity portable chargers take the long length kind of form factor but the iMuto is more short and stubby.
The length is 5.1 inches, a width of 3.1 inches, and a thickness of 1.2 inches.
Overall, the size of the iMuto is not that large we would even say that it’s compact just as a lower capacity portable charger is.
But what does make it seem large is the weight at 1 pound. It’s a heavy power bank that may look small but it’s going to be cumbersome to carry around and as result, you’re going to want to set it down if you want to use it.
Putting it into a back pocket isn’t an option like we did with the Lumina but carrying it to a location and opting to set it down is the best-case scenario for this charger.
Functional Components
The functional components are easy to find and use; the portable charger makes use of very modern design features that puts it up there with Anker and Aukey’s portable chargers as well.
You can find the two USB charging Output ports on the short side, a flashlight between the 2 Output ports, on one long side is where the Micro-USB Input is and the on the other long side is where the power button is.
The most notable feature is the LED display that shows the power capacity in a numeric value and this is on top of the power bank.
The power button is barely used unless you want to check the power capacity of the charger when you’re not charging it. This is because charging begins whenever you connect a device to the power bank and charging stops when there are no devices connected to the charger.
Another use of the power button is to turn on the flashlight by holding it down to turn it on and then holding it down again to turn it off.
More Accuracy with the LCD Display
The use of the power capacity display is really helpful because it gives a more accurate reading than just LED dots and features like these need to be become more prevalent, just how the Lumina 15,000mAh uses it as well.
There’s one negative side effect of the power capacity display, it’s that it uses quite a bit of power, and as a result that can burn into the power capacity and there’s no way to turn it off during charging.

Build
Structure and Material
There’s nothing special about the physical structure with the iMuto power bank.
The charger is separated into 3 pieces with the Top, Bottom, and centerpiece; the material that it’s all made of it plastic.
Sure, it’s a structurally solid build but we don’t recommend dropping the power bank to be taken lightly since it weighs 1 pound and the shock from such a fall can very well damage the charger.
Tech
On the inside is iMuto’s Multiple Safety Protection System that takes advantage of plenty of safety tech like Over-Voltage protection, Over-Current, and Short-Circuit Protection.
iMuto did mention that they have Over-Charging protection but that’s simply not true since the power bank keeps charging even when a device is fully charged.

iMuto 20,000mAh Quick Charge Power Bank
Reliability
Like most high capacity portable chargers, it’s reliable.
The power bank doesn’t suffer too much from losing power from its initial power capacity and the charging speed isn’t that bad with a max output of 3.1A.
Although the charging speed could be better in comparison to power banks like the Anker PowerCore 20100.
The size is small but you shouldn’t be fooled by it because the weight is heavy at 1 pound and the best way to rely on using the iMuto is to set it down so you don’t feel the cumbersome heavyweight.
The functional components are placed very well, and the use of the Power capacity display is something that should be prevalent on more power banks. With that said, the display can burn into power capacity, so that’s a bit of a negative side effect.

Summary
Power
The power capacity does a good job with staying near its Initial power capacity and just losing a few thousand, but it can still provide plenty of charges to smartphones and just a few charges to tablets. The charging speed could better with it having a max output of 3.1A.
Design
It’s a small high capacity portable charger but don’t let that fool you because the weight is 1 pound.
It’s best to set it down and use it. It begins charging automatically when a device is connected to it and then stops charging when all devices are disconnected from it.
The power button is only used to check the power capacity and the turn on the flashlight. The use of the power capacity display is pretty cool.
Build
Nothing special about the build, with it being made out of plastic, it’s solid but don’t drop it since it’s heavy. It has quite a few safety tech features but it doesn’t stop charging automatically even though it says it does.
Reliability
Like most high capacity power banks, this one is reliable if you want constant power without the constant recharge.

Conclusion
The iMuto is bringing a somewhat new age of high capacity power banks. The use of small size and heavyweight is questionable but it does well.
However, the most important thing was the numeric display showing the power capacity, sure it’s easier to tell the power capacity more accurately but power capacity is lowered with the usage of it. Perhaps the convenience will outweigh the sacrifice.
