Review: iMuto 20,000mAh Quick Charge 3.0 Power Bank

iMuto 20,000mAh Quick Charge 3.0 Power Bank











  • High Power Capacity
  • Features Quick Charge
  • Has a Port that can Output 2.4A
  • Is able to recharge at Quick Charge speed for a faster recharging


  • Large and Heavy

Charging electronic companies usually make multiple different versions of their power banks because they know that the needs of everyone are different.

Some power banks have smaller power capacities and therefore they have smaller sizes and are lightweight. Those kinds of power banks aren’t very useful for multiple charges, though.

That’s why charging electronic companies have a separate category for their higher capacity power banks because those are the kinds that are going to charge devices multiple times over.

In this review, this iMuto power bank is quite similar to the 30,000mAh version and 20,000mAh version of the iMuto power bank that we’ve already reviewed on Charger Harbor. However, there are indeed differences with this iMuto 20,000mAh Quick Charge power bank. Let’s see what it has.

Vinsic Slim 20,000mAh Power Bank


Power Capacity:

The power capacity starts at 20,000mAh. Depending on how you use the power bank, the Output power capacity, the capacity that you’ll actually be receiving, is going to fluctuate.

This is because one of the charging ports on this iMuto power bank has a Quick Charge charging speed and the other charging port is a normal 2.4A charging port.

Using the Quick Charge charging at the same time as the 2.4A port is going to make the conversion of energy less stable and you’re going to receive 60% of a conversion with that.

However, if you’re using either Quick Charge port as a normal port or using the 2.4A port as well, then the conversion is going to be or stable and give a 70% conversion rate during charging.

To simply put.

Quick Charge charging – 60% efficiency – 12,000mAh of Output Power Capacity

Normal Charging – 70% efficiency – 14,000mAh of Output Power Capacity

Power Capacity for Smartphones:

With that said, for the most part, you’re going to be able to get 4.5 full charges for most smartphones.

Although we’re mostly measuring it from smartphones that are compatible with Quick Charge and those kinds of smartphones usually have power capacities close to 3000mAh. If you’re charging smaller battery capacity smartphones, then you’re going to be able to get about 6 full charges for them.

So high capacity power bank title that this power bank has does stand true even after the conversion of power has taken place.

Power Capacity for Tablets:

Going into charging tablets, things are still great because the power capacity to use is still going to give out full charges. If you’re either charging an iPad Mini 2 or 4, the iMuto power bank can give either  1-2 full charges with all of its power capacity.

If you’re charging high range tablets like the iPad Air 2 with its 7,000mAh power capacity, then you’re going to fair about 1.7 full charges.

Or if you’re charging a Full Sized 12-inch iPad with 10,000mAh battery capacity, then the power bank will be able to charge it once to its full power and still have some power left over to use as well.

Overall, the power capacity that this iMuto portable charger has is indeed high power capacity and you’re going to be able to charge numerous types of devices either multiple times or the high capacity ones a few times or once. Very versatile power.

Output Charging:

There are two USB charging ports.

The Quick Charge Port:

One of the USB Ports features Quick Charge 3.0 and it has to charge speeds of 5-6V/3.0A | 6-9V/2.0A | 12V/1.5A. So you can charge your Quick Charge compatible smartphones with this port. Also if you’re using non-compatible Quick Charge devices with this port, then it’s going to Output 5V/2.0A charging speed.

The Normal USB Port:

The other USB port has a 5V/2.4A charging speed and it’s going to charge most Non-Quick Charge compatible devices at their max charging speeds. For example, this port is labeled iM-Power and is able to charge tablets like iPads at their max charging speeds because iPads have a max charging speed of 2.4 Amps.

Overall, the Output charging is quite powerful for both standard charging devices and those that are compatible with Quick Charge and we like that the power bank doesn’t favor one over the other too much.

Input Charging:

The recharging is actually faster than most 20,000mAh power bank on the market because it uses Quick Charge tech to recharge. The iMuto power bank recharges at speeds of 5V/2A | 9V/2A | 12V/1.5A via a Micro-USB Input Port. With that said, if you want the power bank to recharge at Quick Charge speeds, you must use a Quick Charge wall charger.

It’s with a Quick Charge wall charger that you’ll be able to charge the power bank within 6-7 hours.

Size and Weight:

The most noticeable difference between this iMuto power bank and its other versions is the size differences.

This iMuto power bank is generally a lot longer and thinner than the other ones we’ve reviewed.

It has a length of 6.7 inches, a width of 3.2 inches, and a thickness of 0.9 inches. So quite a lot longer but it’s easier to hold because it’s thin. Although, the bad part about this is that the power bank weighs 1 pound and so for the most part, this isn’t a power bank that you’re going to be holding in your hand for very long.

Functional Components:

The 2 USB Output charging ports, the Micro-USB Input port, and the power button are all on a single short side of the power bank. On top of the power bank is where there’s an LCD power capacity display that shows the power capacity in a percentage manner.

It’s an easy to use power bank because charging automatically starts when you plug a device into the power bank and that leaves the power button with the main function of checking power capacity. The LCD display is integrated seamlessly within the body of the power bank.

Structure and Material:

All the black parts of the iMuto power bank are made of plastic and the portion where the charging ports are is made of Aluminum Alloy that’s colored in a Goldish color. It’s a solidly build a charger that doesn’t have too many separate pieces holding it together.

Also, the choice of not making the hold portable charger Aluminum is a great decision because then that would make it very heavy.


On the tech side, the power bank doesn’t do anything too special but it does use the basic safety tech features that are able to keep you and your devices safe during charging.


This iMuto power bank is going to be very useful for those that own either Quick Charge compatible devices, as well as standard charging devices.

You don’t need a Quick Charge device to get the most out of this power bank and that’s the best part because it can still deliver fast charging speed even if you use a Non-Quick Charge device on the QC port.

Charging speeds are universally quite fast with this power bank, the same goes for the recharging speeds because you can use a Quick Charge wall charger to recharge the power bank faster.

It’s the size and weight of the power bank that can pose a problem with portability because it’s large and heavy.

It features Quick Charge tech that’s able to charge QC compatible devices at their max charging speeds, and you can also charge standard charging devices at their max charging speeds using the 2.4A port. Even recharging is really good because you recharge the power bank at Quick Charge speeds.

There’s a lot of power capacity to use even after its conversion.


It’s long and thin, but the main problem is that it has a heavyweight of 1 pound. The use of an LCD power capacity display is a lot more accurate than just a couple of dots.


It has a solid build, nothing too special though so don’t go dropping it.


The iMuto power bank is reliable for those that are looking for a high capacity power bank and for fast charging at the same time. The best part about this is that it can be very useful for both Quick Charge device users and normal device users.
