Review: EC Technology 22,400mAh Power Bank

EC Technology 22,400mAh Power Bank











  • A High Capacity that can last for days
  • It's a simple design that's easy to use and it's quite portable enough to carry in a single hand
  • 3 Charging Ports means that you can charge 3 devices at once.


  • The Max Output for charging is only 3.1A, so if you're charging 3 devices at once, each of them will charge slowly.
  • It can heat and lose quite a lot of power capacity.


High capacity power banks are not only able to provide a high capacity but they’re also able to provide more traits that make a charging experience better.

Having a high capacity can only be as good as what the charger has to offer. In this case, this EC power bank has some things to offer but are they things that make the charger better? Well not exactly.

This EC portable charger is able to talk the talk but its got some kinks that it still needs to work out a little bit. Now let’s take a look if high capacity is all a power bank charger needs to be awesome.

Power Capacity

The first thing that you’re going to need to know about this EC power bank is that its got a power capacity of 22,400mAh.

With that said, quite a big chunk of the power is gone during charging and as a result, you end up with an 18,000mAh power capacity.

Just remember, this isn’t to say that the company lied about the power capacity, it’s just that the power capacity that you’re really going to receive after heat during charging, takes some power away and you end up with 18,000mAh.

However, this is still a big problem because in some cases this depletion in power can be avoided and be closer to the initial power capacity that a charger is supposed to hold.

With all that said, the 18,000mAh power capacity still places this power bank charger to still hold plenty of charges within it.

You can expect to charge many smartphones over 4 times. A tablet like an iPad can charge about 2 times or other tablets with smaller battery capacities can charge even more times.

Overall the power can last for days and probably even weeks depending on your usage with this charger.

Now onto charging capabilities of the charger. The power bank has 3 charging outputs and each of them is able to charge at different charging speeds.

The most notable thing about the charging Output ports is that they have labels. The charging ports are labeled as iPhone, Samsung, and iPad. The logic here is that you’d plug in the device you need to charge that corresponds to the charging port. Here are the charging speeds each of the ports.

Output Charging:

iPhone: 5V/1.0A

Samsung: 5V/2.0A

iPad: 5V/2.4A


Powerful Charging

These charging speeds are actually pretty good considering that one is at the max standard charging speed (The iPad charging port) and another one is at 2 Amps.

The ports are somewhat labeled correctly as well because it makes sense to connect an iPad to the iPad port because that’s the max speed that it will charge at.

However, it makes sense to plug a smartphone into either the Samsung or iPad port if you’re not charging any tablets at all; because many smartphones can actually charge beyond just a single Amp, so the iPhone port is really only useful if you’re charging a tablet on one of the charging ports.

Then there’s the bad news to go with this power bank’s charging capabilities.

But has a Limit

Even though each of the ports is able to deliver some fast charging, they’re not able to deliver it all together. This is because the max output for the power bank is only 3.1A.

So if you plug an iPad into the iPad port the Output will be 2.4A and then if you plug a smartphone into the iPhone port, then the Output will be 3.4A; but that’s impossible since the max output can only be 3.1A.

So the iPad charging speed will be cut down to 2.1A so the total Output can be 3.1A.

This is where the power bank’s powering comes to a rather minimal disappointment because if you want to charge 3 devices at the same time, then this power bank will charge each of the devices at 5V/1.0A, which is some really slow charging.

However, this doesn’t mean that is power bank charges slow. It just means that you have to strategize on what you want to charge with what. Charging 2 smartphones is good. Charging 1 smartphone and tablet is good. But charging 3 tablets at the same time or 3 smartphones at the same time will not provide an ideal charging experience.

Input (Recharge Speed)

The recharging speed of this power bank is to be expected at 5V/2.0A via a Micro-USB Input port, and you can expect it to be fully recharged in about 8-9 hours.

For it to charge in the time that I mentioned, I highly recommend using the wall charger that is capable of charging at 5V/2.0A or higher, otherwise, anything lower will result in the power bank being recharged at a much slower rate.

Size and Weight

Like many other high capacity power banks, this one is quite big and heavy. It comes with the abilities of the power bank and it’s not something to be surprised about because of the bigger the capacity of a power bank, the more charging tech it has; means the bigger it will most likely be.

The portable charger’s length is 6.3 inches, 2.9 inches in width and it 0.8 inches in thickness. The weight of the charger is 1.4 pounds.

So ultimately, the “Portable” aspect of this charger is somewhat not present. Sure the power bank can be held in a single hand but are you really going to hold it in your hand, charge your phone and still use your phone? It’s half a foot long and it’s heavy.

With that said, it’s best to opt for the setting the charge down and using it. You can put it in a bag and use it at a location that you plan on staying.

pic-2Functional Components

The functional parts of the wall charger are in a few different places. The 3 charging ports are lined up one after another, with their labels under each of them but not the charging speed.

There’s a LED light that’s above the middle port. The LED light has 3 settings that can be changed via the power button, and the 3 setting of the light is Soft Light, Hard Light, and an SOS light.

Speaking of the power button, you can find it on the left side of the power bank, near the charging ports. Its functions are very limited because it’s only used to check the capacity of the power bank, turning off the power bank. If you hold it down for about 5 seconds.

Speaking of the power button, you can find it on the left side of the power bank, near the charging ports. Its functions are very limited because it’s only used to check the capacity of the power bank, turning off the power bank.

If you hold it down for about 5 seconds, it changes the LED flashlight settings. There are 4 LED power capacity indicators on top of the charger. You can find the Micro-USB port to the right side of the power bank.

The power bank has the ability to begin charging automatically and it turns itself off once the device it’s charging is fully charged.

When you recharge the power bank, the LED power light blinking according to what capacity the charger is at. So if it’s nearly full, the power bank will have only a single LED light blinking while all the other lights are just constantly on. Once the power bank is at full charge, all the LED lights are on.

The design of the charger is really straightforward and highly resembles the design of the KMASHI power bank, with a smooth and straightforward design.

Structure and Material

The entirety of the power bank is made of plastic and the structure has 3 main pieces that are connected to make the charger whole.

The top and bottom piece and a centerpiece of where all the functional parts are held are what make the power bank whole. Overall the charger does a great job at being structurally strong.


The charger has support for plenty of safety tech that includes Over-Voltage Protection, Over-Current Protection, and Short-Circuit Protection.

So even with its large capacity and ability charge 3 devices at the same time, you expect your devices to be very safe.

With that said, though, the charger can heat up and the result is the lessened power capacity. Even with its limited charging speed, the power bank is still able to heat up and I think this it’s bad quality on part of the batteries.

EC should consider the way they handle their temperature control during charging because this way the power capacity could be closer to the initial capacity.

The heat will only lessen the  Amp current being sent out is lessened. Long-term heat will be able to damage the batteries.

Vinsic 28,000mAh Power Bank with Quick Charge


This power bank poses itself to be reliable and it tries hard to deliver but I really don’t understand how it’s reliable when you’re going to be receiving a very mediocre charging speed.

The max output of this power bank is 3.1A. It would actually make more sense to get a 2 port power bank that has a similar power capacity like the PowerCore 20100; because it has nearly the same capacity but the max output of the PowerCore 20100 is 4.8A.

So this leaves most of the reliability to the capacity and it definitely delivers because of the power capacity, even with its missing chunk after some is lost during charging, is still able to deliver plenty of charges to smartphones and tablets.

The power capacity can very well last for days depending on the way you use it. And that’s really where most of the reliability end.

Sure, you can charge 3 devices at the same time, but you have to prioritize what devices you want to charge with what. You can’t charge 3 devices all at once and expect them all to charge at their max speeds because the max output is only 3.1A. So for fast charging, you have to be selective.

The portable charger isn’t very portable so you’re going to have to set it down and use it. Although this goes nearly all high capacity power banks since they’re heavy and large; and this charger is not an exception.

iMuto Portable Charger X6 30,000mAh



It’s got a real power capacity of 18,000mAh and can last for a few days with constant use.

The charging power of the power bank is on the weak side with 3 ports but the max output of the charger is only 3.1A. As a result you have to prioritize what devices you want to charge; otherwise, you’ll be stuck with slow charging.


Like many high capacity portable chargers, this power bank is big and heavy.

It’s not the best power bank to hold and use, but it will do very well if you set it down and use it.

All the functional parts are easy to find and use. Its design features are quite welcome with the charger being able to start charging automatically, and the power button being able to control the LED light, checking the power bank’s capacity and turning off the charger.


Made entirely of plastic throughout all of its pieces, the charger’s structure holds strong. On the inside is an array of safety tech that keeps your devices safe.

The charger can heat up quite a lot, which is the reason for such a loss of power capacity and the heat can damage the battery in the long-term.


It’s nearly a perfectly reliable charger when it comes to its capacity because it’s so big.

However, the reliability logic goes downhill after you consider the charging power. The charger only has a max output of 3.1A, so if you’re charging 3 devices at once, then they will charge slowly.

It’s a big charger, which is to be expected, so it’s best to use it in one place. But even with that logic, for what you’re getting, the charging experience will be mostly mediocre.

More High Capacity Power Banks

Specs of the EC Technology 22,400mAh Power Bank:

  • Capacity:            Advertised: 22,000mAh             Output Capacity: 18,000mAh
  • Output:  Max Output: 3.1A
  • Input: 5V/2.0A via a Micro-USB Input port
  • LED Power Indicators: 4 LED Power Capacity Indicators
  • Size: 6.3 x 2.9 x 0.8 inches
  • Weight: 15.4 Ounces


The EC high capacity portable charger tries to be better than it is, but it ultimately falls short.

The power capacity is still large, even with a good chunk of it missing. Although that missing power can be corrected if the tech was better at handling high temperatures.

The main thing to watch out for other than the large size and heavy weight of this power bank; is the charging speed and the charging ports. There are 3 ports but the overall max charge rate is 3.1A, which is very limiting if you plan to charge 2 devices or more.
