Review: OmniCharge Portable Power Supply

OmniCharge Portable Power Supply











  • Can Power Appliances because it uses a AC Outlet
  • Has a DC Port and also 2 USB Ports with one USB Port using Quick Charge
  • Uses a OLED Screen to show real-time stats of the OmniCharge


  • Can be quite large and heavy

Power banks are the most innovative solution to charging in general and the reason for that is because they’re portable.

They can literally go with us anywhere, so when a power bank has a high power capacity, multiple USB ports or a fast charging technology that’s implemented with it then that is able to go with us anywhere and everywhere.

What makes power banks go a step further is when they use AC Outlets, and DC Outputs because you can use the power bank for more than just charging, it can also be used to power appliances.

An example of a power bank/power supply is the Anker PowerHouse, as it has a massive power capacity and lots of power options that made it one of the perfect portable power sources out on the market.

With that said, the Anker PowerHouse is quite large, which is why you should probably consider the Omnicharge AC Portable power bank.

It has a lot less power capacity than the PowerHouse but its portability and usability are still just as high with the power bank having abilities that are going to be useful to have when you’re on the move. Let’s take a closer look at what this Omnicharge has to offer and if it’s really as useful as it says it is.

Power Capacity:

There are two different versions of the Omnicharge power bank, as it has has a 13,600mAh version and the other type has a 20,400mAh power capacity. In this case, we’re going to be reviewing the Omni Charge with the 20,400mAh power capacity, which is knowns as the Omni 20 and the low capacity one is called the Omni 13.

The Omnicharge has a lot going on with it when it comes to charging power and the conversion of its power capacity can change depending on the way that you’re using it.

The main reason for that is because this power bank has a few ways that it outputs its power. It has an AC Outlet, a DC Output port, and two USB ports. So it can output 100Watts of power at once if you’re using the AC or DC Output ports, other times the power bank could just be outputting 4.8A from its USB ports.

With all that said, Omnicharge states that the battery efficiency of the power bank is 90%, which would mean that you would be receiving an Output power capacity of 18,360mAh.

That’s being quite generous though, so we’re going to assume that you’re at least going to be getting an average conversion rate or maybe even worse because if you’re using the AC or DC ports, then a lot of power can be used and that can worsen the conversion rate.

3.7 x 20,400 = 75,480 / 5 = 15,096

Power Capacity for Smartphones

If you’re using the Omni 20 moderately, then you’re most likely going to be receiving an Output power capacity of 15,096mAh.

It’s with this Output power capacity that you’re going to be able to charge smartphones multiple times. An iPhone SE or iPhone 7 with their somewhat low battery capacities are able to charge to full power about 8 times.

Then there are smartphones that have very high power capacities such as an iPhone 7 Plus, a Galaxy S8 or a Google Pixel XL that can charge to full power 5 times. So charging smartphones with the Omnicharge power bank will provide a good experience.

Power Capacity for Tablets

Charging tablets is also a good way to use the power bank because iPads like the iPad Mini 2 or 4 can charge to their full power about two times and a full-sized tablet such as the iPad Air 2 can charge to its full power about two times also.

Power Capacity for Laptops

Of course, you’re only using a fraction of the power bank’s capabilities if you’re only charging tablets and smartphones because you can also charge laptops with it too.

However, when you charge laptops with the Omni 20 power bank, then the conversion of power may worsen because the charging speed is faster. With that said, you can charge a MacBook Air to 100% of its full power, a MacBook Pro 13” can charge to 70% and a MacBook Pro 15” can charge to 60% of its full power.

The power capacity of the Omnicharge power bank may not be the highest out there but it can definitely be useful in different ways.

USB Port Charging:

There are two USB ports and each of the two ports has a charging speed of 5/3.0A but they do have their differences though. The top USB port has a standard charging speed of 5V/3.0A and the bottom USB port Features Quick Charge so it can charge compatible devices at their max charging speeds.

With that said, a standard 5V/3.0A charging speed is still very impressive because most USB ports on power banks have a max standard speed of 5V/2.4A but these USB ports go a bit further than that.

Another important factor to know about the USB ports is that they have a max Output of 4.8A. So if you want to take advantage of as much power as you can, it’s best to charge a single device at a time.

If you’re charging two USB devices at the same time and the max Output of 4.8A is being reached, then the charging speed of each of the two ports will be 5V/2.4A.

AC Outlet:

The AC Outlet is powerful because it’s able to Output 120V/100Watts. So you can basically charge most laptops with this AC Outlet and you can even power some small appliances that are within the range of the AC Outlet’s capabilities.

Some appliances that you potentially power are Mini fridges. Take a look at the bottom table to know more about what you’re able to power and how long it would take to charge a few of the laptops that are on the market.

DC Output Port:

The DC port can be used as an Output and it has an Output power of 150V. So it’s able to charge most laptops at their full power.

Input Charging:

When it comes to recharging the Omnicharge, things are very versatile and the reason for that is because it can be recharged through a lot of ways.

It comes with its own recharge Adapter called the Omnicharge Fast Charger and that is capable of recharging the Omnicharge at its max charging speed.

The recharging power that it’s capable of is 4.5V-80V/1W-40W and that is one of the main reasons that it’s able to use other sources of recharging and not just its own Fast Charger.

Take a look at the table below to know the multiple ways that you could recharge the Omnicharge:

Power Supply for RechargingDuration Until a Full Recharge
Omnicharge Fast Charger2 hours for a Full Recharge
Laptop Adapter (19V/2.4A-4.74A2 Hours for a Full Recharge
AC/DC Charging adaptor2 Hours for a Full Recharge
USB Port5-10 Hours for a Full Recharge

Car Power Port2-3 Hours for a Full Recharge
Electric Scooter Charger (48V/2A)2 Hours for a Full Recharge
Electric ToyCharger (14.2V/1A)4-6 Hours for a Full Recharge

As you can tell, the Omnichage is quite useful even when it comes to recharging it. Although most of the time you are going to want to stick with its Fast Charger because it’s able to recharge it the fastest.

Size and Weight:

The Omnicharge, with its abundance of charging and powering capabilities, isn’t actually all that large. I mean it’s quite large and heavy and most of the time when you’re using it, you’re going to want to set it down and charge your devices or power an appliance. With that said, it can still be taken anywhere and be useful wherever you go.

Omni 13 Dimensions and Weight

The Omni 13 is the smaller of the two versions and it also has a lightweight because it has a lower power capacity. The Omni 13 has a length f 5.2 inches, a width of 3.3 inches and a thickness of 0.9 inches. It weighs 0.8 pounds, which is about 12 ounces.

Omni 20 Dimensions and Weight

Then the Omni 20 is the larger and heavier version of course since it has a higher power capacity. The Omni 20 has a length of 5 inches, a width of 4.8 inches and a thickness of 1 inch.

The weight of it is 1.4 pounds. Either way, each of the versions is most likely going to be set down for when you use it and you’ll have no problems taking this from one location to another because it can fit into a bag or you can just carry it in your hand.

Functional Components:

The way that you can use the Omnicharge needs a bit of clarification and that is exactly what we’re going to do here at Charger Harbor. Let’s just go over where certain parts of the power bank are, then we’ll get to actually using the charger.

The Omni 20 has the AC Outlet on one side alone. Then on the short side of the charger is where there’s a power button, an OLED screen, a button for the AC/DC Outlets to turn them ON/OFF, then under that button is the USB ON/OFF button. On the other long side is where you’re going to find the DC Output port.

The OLED Screen has few icons on it that may look confusing at first but once you know what’s going on, the Omnicharge is quite easy to use. Well, the first thing is first, you must press the power button to turn it on.

At the top, the OLED screen shows what powering/charging parts that you’re using with the Omnicharge. So if you have the USB ports activated, then you’re going to be seeing a “USB” Icon and if you’re using the AC or DC ports then you’re going to be seeing an AC outlet logo or a “DC” logo.

It’s just a way of telling you what’s happening when you’re using the Omnicharge.

Another thing that gives you great info about what’s happening is the logos under the powering/charging options that are being used.

LCD Logo Meaning

Top Left Battery Logo – This battery shows the Input power that’s being used for when you’re recharging it.

Top Right Time Logo – This tells you the amount of time that it has left before it’s fully depleted of its power.

Bottom Left  Battery Logo – This battery logo shows you how much power is being outputted.

Bottom Right Temp Logo – This tells you the temperature of the Omnicharge which can be quite helpful just in case it starts overheating and you can stop using the Omnicharge.

The Omni charge even has customizable features such as:

  • AC/DC Inverter Usage
  • USB Output Connection ON/OFF
  • Auto Shut Off Timing

Structure and Material:

The build quality of this Omnicharge is great. It uses 6 separate pieces to make itself whole and all of the pieces are connected in a solid way.

The power bank is not a Rugged one so make sure that you don’t go dropping it. However, it’s still perfect for everyday use because you can plug an AC Adapter into the AC Outlet and the charger’s plates don’t come loose. So the build quality of the Omnicharge is on par with its usability features.


The tech on the inside of this power bank is quite great because it does a great job of providing the best possible charging experience.

It uses Max Power Point Search Technolgy, which is able to accept a wide range power for when the Omnicharge is recharging because that way you’re able to utilize different ways of recharging if you don’t have the Fast Charger with you.

Going into the safety segment of this power bank, it uses a Safety Check Algorithm. This type of technology is able to detect problems and correct them accordingly. This type of tech is very useful if something goes wrong during powering or charging, so it can automatically turn off.


The Omnicharge is one of the most useful power banks on the market because it uses a wide range of power capabilities that are going to be useful no matter what you’re going to need power for.

The two USB ports have fast standard charging and one of the ports even uses Quick Charge to charge compatible devices at their max charging speeds.

The other most useful parts of the charger is that use an AC and DC Output ports so you can charge devices such as laptops or power appliances too. This power bank has so many abilities and it can still be taken anywhere and everywhere. That is what we call it reliable.

The power capacity is able to charge devices such as smartphones and tablets to full power multiple times. There are also many laptops that can charge to full power but then there is a lot that cannot charge to full power because the conversion of power is worse when it comes to charging laptops.

The use of AC and DC Outputs make this more than just a power bank, it’s a portable power source that can power appliances too.


It’s quite small on the size side, but it’s heavy on the weight side. The power bank can still be taken anywhere despite its size and weight. It does have a few buttons and you do need to press a few of them to actually use the Omnicharge.

Also, the OLED screen tells you lots of things that are happening real-time as you charge.


It’s a not a Rugged power bank but it’s a still a tough charger that can be used daily and the structure holds strong for the long-term too.


With all of its capabilities, the Omni 20 comes together to make a portable power experience one of the best out there because of its power capacity and all of it powering abilities that come with it.
