Even though it's not the smallest power bank out there, the iMuto 20,000mAh Portable Charger offers incredible value thanks to its low price and huge capacity.

Weight: 458g (1.01 lbs)
Time to charge itself: 13 – 20+ hours (depends on wall charger’s voltage)
Compatible with: Tablet, laptop, iPad/iPhone, Android and other smartphones, digital camera etc. (any micro-USB supported device)
The iMuto 20000mAh Taurus 4 is a great competitor for the Anker PowerCore 20100. They’re both relatively small for their power and are offered at a fairly affordable price point. In this review we’ll be taking a look at the iMuto 20000 portable charger to see how it holds up against the big players in the industry.
Design and Portability
Before we go into the portability of this device, we’re going to talk about its construction. The iMuto 20000 portable charger is encased in black plastic, with a nicely bronzed rim. While it doesn’t look as cool as some power banks like the Innogie JA Alienpower, and doesn’t feel as sturdy as the Anker PowerCore 20100, it does alright for itself in the looks department. The powerbank has a very decent design that doesn’t try to be all fancy. It would’ve been nice if it was made of aluminum to make it more robust, but we get that iMuto wants to keep the weight as low as possible and used plastic instead.
Now onto its size. We’re very used to seeing 20,000mAh power banks that are huge and weigh more than the tablet you want to charge with it. However, the iMuto 20000mAh is relatively small for a power bank of its capacity. It’s only 5.12 x 3.07 inches and smaller than your hand. One downside though, is that it’s quite thick.
According to iMuto, the power bank is smaller than an iPhone 6 Plus, which is a bit misleading. Well yes, technically it’s smaller in size than an iPhone, but what they forget to mention is that it’s as thick as four iPhone 6’s stacked on top of each other. Still, with the exception of the Anker PowerCore 20100, the iMuto 20000mAh is one of the most compact 20,000mAh powerbanks we’ve seen yet. It doesn’t quite fit in your pocket, but easily goes in your backpack, handbag, book bag or whatever bag. It even comes with a nice travel pouch so you can carry it by hand.
Pass through charging is a feature we rarely see in powerbanks. Pass-through charging simply means charging one or more devices in the powerbank while the powerbank is being charged itself. The iMuto 20000mAh powerbank supports pass-through charging and has two charging ports. Which means you can charge two devices plus the power bank at the same time. This can save you a lot of time as you now don’t have to take turns charging. A very handy feature. However, I’d recommend you to not use pass-through charging too often though, as it can shorten the battery life of both your device and the powerbank.
Another thing we really like seeing is smartports. The iMuto has intelligent charging ports that detect your device and deliver the quickest possible charge output for it. This helps preserve the longevity of your battery and also provides you with fast charging speeds. Both of the ports on the iMuto 20000mAh are smartports that can give an amperage output of up to 2.1A for a total of 4.2A. However, if you’re charging two devices simultaneously, the output will be split to a maximum of 3.1A. Which means that when simultaneously charging two tablets, charging time for one tablet will be slower. This is a bit of a flaw and we’d rather see the two smartports work independently, like the Anker PowerCore 20000’s can do.
A unique feature we see for the first time, is a digital display that shows the exact percentage of charge that’s left in the powerbank. Most powerbanks we see have three or four LED battery indicators, which can sometimes leave you guessing how much charge there’s really left. The iMuto 20000 portable charger’s digital display shows exactly how much battery you have left in digital format, which is an amazing feature I really like. If it was up to me every power bank would have this feature.
As always, there’s a flashight function too. it’s quite bright. although not as bright as the Dulla flashlight.
The power of the iMuto 20,000mAh is its biggest selling point. It’s very affordable but boasts a massive capacity of 20,000mAh, which is double the capacity of the average power bank in its price range. Keep in mind though, that some power is always lost through charging and that 20,000mAh doesn’t mean you can charge your 2000mAh battery ten times. The advertised numbers are usually a bit exaggerated. This is not unusual and almost every brand does this. The iMuto 20,000mAh is good for about five to seven charges for your average smartphone. It charges an iPhone 6S about six-ish times, and a Samsung Galaxy S6 4.5 times. Which is great if you’re going out for a weekend camping, or just anyplace where there’s no outlet available for a while.
It’s also perfectly capable of charging big tablets like the iPad Air 2 which it can charge almost twice fully, and it can even charge a 12” Macbook once. However, there are better options for laptops. So if you’re looking for a dedicated power bank to charge your laptop I would suggest you look at the RAVPower 23000mAh Portable Charger or the MAXOAK 50,000 Portable Charger.
The powerbank charges devices fairly quickly, courtesy of its smartports that automatically send the right output amperage to your device. Charging your iPhone takes less than two hours. But, one downside to a charger as powerful as this, is that it takes a long time to recharge when it’s empty. Depending on the wall charger used, it can take from 13 to 20+ hours. However, considering you won’t have to charge it that often due to it’s big capacity, it’s not that bad.
The iMuto 20,000mAh portable charger is great for people who go out hiking, camping, fishing or do other activities where you’re removed from an outlet for a long time. It’s not the smallest power bank, but packs a wallop. For a powerbank with such a monstrous capacity, it’s astonishing how low-priced it is. If you’re looking for a compact power bank for occasional use, the iMuto 20,000mAh is definite overkill, but for those who’re looking for an affordable, relatively portable power bank to provide many charges, it is an excellent option.
