Review: Suaoki 220Wh/20,000mAh Portable Generator Power Supply

Suaoki 220Wh/20,000mAh Portable Generator Power Supply











  • Has a 200Watt AC Outlet
  • Use 2 DC and USB Ports
  • Very portable for a Power Supply since it can be held in the hands


  • Doesn't have a very high power capacity as other larger Power Supplies

Most of the time when it comes it comes portable power supplies, they usually have high power capacities and that makes them able to charge device many times to their full power capacity.

Having a very high power capacity also means that these portable power supplies are able to power appliances for a long while. It’s basically normal and expected for a portable power supply to be large and heavy because of how much power capacity it holds and also with all of its powering/charging capabilities that it has.

That’s not always the case though. I mean portable power supplies are indeed going to be large and heavy, however, there are ones that are large and heavy on a smaller scale.

That is what this Suakoki 20,000mAh Portable Power Supply exactly is since it has a power capacity that most high capacity power banks have and yet it has quite a lot of ways to power and charges your devices.


Power Capacity:

The power capacity of this portable power supply is 20,000mAh and the Output capacity that you’re actually able to use is going to depend on how you’re using the portable charger.

Mainly because there are quite a lot of ways that you could use this power source. We’re just going to calculate the average conversion that you’re likely to get but this conversion of its power capacity can definitely change depending on how you go about using the power supply.

Most of the time you’re going to be able to use an Output power capacity of 14,800mAh and this is pretty good for charging smartphones, tablets, and laptops as well.

Power Capacity for Smartphones

As most smartphones are going to be able to charge to their full power multiple times. A smartphone that has a low capacity such as the iPhone 7 with its 1,960mAh of power capacity can charge to its full power 7.5 times.

Then if you’re charging smartphones that have higher capacities such as the Google Pixel or the Galaxy S8 that have battery capacities within the 3,000mAh range, then you’re able to charge them to full power about 4.5 times.

Power Capacity for Tablets and Laptops

Charging tablets and laptops with this power supply is a great use for it, although, for the most part, you’re going to want to charge laptops rather tablets.

The reason for that is because this power supply is able to charge laptops because it has AC Outlets and also DC Output port and you’re going to want to allocate the power capacity to laptops more.

For charging tablets, it would be better to use a traditional power bank because if you charge a tablet with this power supply it’s going to take out a good chunk of power by doing so.

Using the power capacity to charge a laptop, which is something that the power supply is specialized in being able to do, is something that is a very good idea.

Output Charging:

USB Ports:

There are two USB ports on this power supply and each of them has a different charging speed. There’s one USB port that has a charging speed of 5V/2.1A and another USB port that has a speed of 5V/1.0A. You should use the 2.1A port first because it’s going to give the faster charging speed and you should only use the 1A port for when you’re charging two USB chargeable devices at once.

DC 12V Output Ports:

The two 12V Output ports are going to be most useful for if you’re charging a laptop with the portable power supply and they’re both capable of outputting a charging speed of 12V/5.0A. Enough power to charge most laptops.

AC Outlets:

This Suaoki 20,000mAh power supply has two AC Outlets. There is one 2-Prong AC Outlet and then there’s one 3-Prong AC Outlet.

The max Wattage Output of power is 200Watts and that’s able to power any appliance that runs off of 200W of power or less.

200Watts of power is quite a lot and if you’re just using a single AC Outlet then you have the full wattage of power available to use with the appliance that you want to power up, this is good for powering mini-fridges, TVs, lamps or any other appliances and devices that fall at or under 200W.

If you’re using two AC Outlets at a time then you really have to know what the total power consumption of each of the devices that you plan on connecting to the power supply, since two appliances can easily exceed 200W of power if you don’t know the power requirements of them.

The wattage power of the power supply is Pure Sine and in terms of other power measurements, it’s capable outputting 110V/50Hz of power.

Input Charging:

There are two main ways to recharge this power supply and that would be through its AC Adapter or a Solar Charger.

If you’re charging it through its AC Adapter then it’s going to have a recharge speed of 15V/4.5A and that results in a full recharge time within just 4-5 hours. Or you can recharge it via a 60W Solar charger or below and that results in basically the same charge time but the charging time can be slower if you’re using a slower Solar charger then.

Size and Weight:

Compared to other portable power sources, this one is quite small and lightweight and you’re going to be able to take it to most places without any real problems as it has a handle at the top that makes it easy to hold.

This Suaoki 20,000mAh power supply has a length of 9.8 inches, a width of 6.3 inches and a thickness of 3.4 inches. The weight of the power supply is 5.5 pounds.

Functional Components:

The functional parts of the power supply are easy to find and that’s because they’re just on two shorts sides of the power supply.

The short that has most of the functional parts have:

  • Two AC Outlets
  • Two USB Ports
  • Two 12V Ports
  • Power Switch

Then on the other side of the power supply is where there’s the DC Input port and the Cooling Vents. At the front is where there are 5 LED power capacity indicators that show how much power is left to use, so each light is basically in increments of 20% of the power that it has.

You can basically use all of the powering and charge options at once, it’s just once you surpass the powering abilities of this power supply then it automatically turns off. Also, it is recommended not to recharge and use the power supply at the same time as that could create lots of heat and possibly damage the power supply.


Structure and Material:

The center silver structure of this power supply is made of Aluminum Alloy and its other parts are made of plastic. Overall, the build quality of this power supply is strong and its components are high quality when you use them.


On the tech side, the power supply keeps things safe with cooling fans and a vent. It’s also automatically able to turn off once the max Output of power is exceeded.


This is actually a highly reliable portable power source with its powering and charging capabilities. Its power capacity is a bit on the short side but that’s also what enables it to be quite small and lightweight in comparison to other portable power supplies that have higher power capacities.

You’re more likely to consider taking this and having a smile on your face if you’re going camping rather than something that has more power.

That said, it actually makes more sense to purchase a portable power supply that has more power because this one may not have enough, to begin with.
