Review: RAVPower 22,000mAh Power Bank Charger

RAVPower 22,000mAh Power Bank Charger









  • High Capacity that can charge smartphones numerous amount of times. Same goes for tablets. This power bank can last for days.
  • Fast charging, with each port being able to deliver 2.4 Amps and a total Output Current of 5.8A.
  • A great design that's easy to use, and allows you to charge 3 devices at once.


  • The Output power capacity can fall severely is you're charging at many devices at once at high speeds.
  • It's Heavy and Big. As a result it's best to set it down and use it.


When you get a high capacity portable charger, you can expect a larger size from it.

However, you can also expect the power bank charger to feature some awesome tech. The usual case for high capacity power banks is that they’re able to deliver a more well-rounded charging experience.

This is usually due to the size increase. With more size, there are simply more things to do about the tech that’s implemented with the charger.

In this review, we’re reviewing the RAVPower 22,000mAh power bank. Of course, it has a high capacity but it’s the other things that this portable charger has is what makes it ahead some of the competition.

Power Capacity:

So let’s talk about the power capacity.  The initial power capacity is 22,000mAh and that’s great.

But if you’ve read our other reviews, then you know that the initial power capacity is not the same as the Output capacity that you’re receiving. Ultimately, the power capacity that you’re receiving will come down to how many devices you’re charging and what speed they’re charging at.

So if you’re charging a single device, and since each of the ports can charge at a max standard charging speed of 5V/2.4A, we can assume that the device that is connected to any of the ports will charge at its max speed.

As a result, each device connected to each of the 3 ports will deduct approximately 2,000mAh of power, because of the heat that is generated through charging. So if you plan on charging a single smartphone, then you can expect a real power capacity of 20,000mAh.

If you’re charging two devices at the same time, then the power capacity will be around 18,000mAh. Lastly, if you charge 3 devices at the same time, the power bank will be Outputting quite a lot of Amp current, resulting in more heat generation, and this can put the Output capacity at 15,000mAh.

Even with the many variables of power capacities that you’ll be receiving with this charger, the title of “High Capacity” still sticks with it no matter how much power capacity it has. Ultimately, you can expect many smartphones to achieve 5 or more full charges.

If you’re using the power bank charger wisely, you can do 2 full charges for tablets like an iPad. You can even charge a Macbook that takes USB Type-C Input when you use a Type-C cable.

The charging delivery that this power bank is capable of is one of the greatest parts of it. Each of the USB charging Output ports features RAVPower’s iSmart tech, which means that each of their ports can supply a 5V/2.4A charging speed; but here’s a little breakdown of it.

Output Charging Speed: Per Port – 5V/2.4A Max Output is 5.8A


So each of the charging ports is capable of charging at 5V/2.4A speed and this charging speed can provide max charging speed to any device that’s connected to it (Except for Quick Charge compatible devices because Quick Charge compatible devices can charge their fastest with Quick Charge technology).

With that said, the power bank can have a max output of 5.8A. This means that two ports can supply a max Output of 2.4A at the same time, which totals to 4.8A. Then the other port can supply a 1.0A because then the power bank’s total Output will add up to 5.8A.

All of this means that you charge 3 smartphones at their max speed because many smartphones charge at 2A or below if they’re not Quick Charge compatible. You’ll be able to charge two iPads at the same time with Max charging speed but if you charge a smartphone with the other port, then it will supply a max Output of only 5V/1.0A.

Conclusively the charging speed of this power bank has a lot of offer and whichever way you configure your devices, you’ll most likely be getting fast charging for any devices that are connected; since reaching a 5.8A output limit will most likely happen if you’re charging devices that can charge at high Amperages such as tablets.


This high capacity external battery can recharge via a Micro-USB Input and the recharge speed is done at 5V/2.4A.

This is a rather uncommon charging speed for input but it makes absolute sense with the power bank’s large capacity. If you’re using a wall charger that supplies a 5V/2.4A Output or higher (Quick Charge wall chargers supply more than just 5V/2.4A), then this power bank will able to recharge in 9-10 hours.

We highly recommend using a wall charger that can supply a 5V/2.4A Output because using anything lower than that, will result in a much slower recharge speed.


Size and Weight:

As we said before, higher-capacity power bank portable chargers have a larger size and weight. The length of this beast is 6.5 inches, the width is 2.8 inches and the thickness is 0.9 inches.

It’s a heavy charger at 14.4 ounces. Putting the size and weight of the charger together, it’s easy to tell that the power bank can be held, but it can’t be held without being cumbersome.

In comparison with more portable, lower capacity power banks, this charger is heavy and big. As a result, the charger can still be portable, but only if you’re setting it down on a surface and using it.

Setting it down and using it is especially the case if you’re charging more than just one device. Charging 2 or 3 devices at the same time with this power bank can’t be easy by holding it. It’s a Hub portable charger, which means that you can take it with you anywhere, but when you have to use it, you’re going to want to set it down.

Functional Components:

All the functional things on the charger are easy to use and see. However, nearly all the functional components on the charger are all in different locations.

You can find all the USB charging Output ports on one side, horizontally placed next to each other; there’s an iSmart logo above the ports to signify that each port is capable of supplying a max charging rate but just remember the limit of 5.8 Amps.


There’s a Micro-USB Input port to the left side of the USB ports, and a power button on the right side of the USB ports. Lastly, there are 4 LED power indicators on top of the charger.

The power button of the power bank is rarely used, other than checking the amount of power capacity that’s left in the charger. This is because when you connect a device into the power bank, it begins to charge the device. When all devices are disconnected from the power bank, then the power bank will shut off automatically in about 5 seconds of being disconnected.

Structure and Material:

This large charger has two main pieces that hold it together, simply a large plastic body piece that’s cut in half down the center of the charger.

However, it’s not just any plastic, it’s made of Thermoplastic Alloy that is fire resistant.

So if the power bank does heat up and potentially start a fire, then the danger will most likely stop with the power bank itself and not spread, it’s a good precaution to have that not many other chargers have.


Inside, there are many safety tech features equivalent to Anker’s Multi Safe protection system. This means that it features things like Temperature Control, Over-Charge control, and Short-Circuit Control.

The power bank is also capable of Pass-Through Charging, but here at Charger Harbor, we don’t recommend using it because it can cause damage to the charger.

In most cases with a high capacity power bank, it’s going to depend on how you intend to use it. If the charger is only relied upon for charging a single device, then you’re simply not relying on it nearly as much as you should be. Perhaps you want to take it with you while you’re walking, but that’s not going to happen comfortably.

Instead, this power bank is most reliable is when it’s used to its relative or max potential. It can provide many charges for many devices and can charge 3 devices at the same time. Each of the ports can deliver a max charging speed. The only way to max out charging is with iPads.

So is this power bank reliable, most definitely. But it has different levels of reliability depending on the way you use it.

Its power capacity can have different variables depending on the way you charge. More devices charging at the same time at high speeds can lower the Output capacity.

The charging speed is maxed out at 2.4A and the total output is 5.8A. So ultimately, nearly any device that you connect it, especially iPads, will be able to charge at their max speeds.


It’s a large and heavy charger but it’s still portable in the way of taking it to a location and using it. All of its functional components sit on different sides of the power bank but are still very easy to use.


The body is made of Thermoplastic, which is rather uncommon with portable chargers. It’s got safety tech that is on the level of Anker’s Multi Safe protection.


Its reliability can vary depending on the way you use it. Use it only for smartphones and you’re not relying on the full potential. Charge 3 devices at the same time, then you’re reliance and experience will be more well-rounded.
