We’ve reviewed another Tech Armor power bank in the past and we noticed that Tech Armor power banks aren’t noticed that much in the charging tech world and we found that to be quite a shame since their power banks hold a lot of value.

In this case, we’re reviewing one of their higher power capacity power banks and although this kind of charger of charges is considered to be one of the big power banks, it’s the way that we’re able to utilize it, is what’s most important.

Power Capacity

This is a Tech Armor power bank with a power capacity of 20,800 and much like its lower capacity version, the Output capacity isn’t too bad.

Overall, it has a conversion rate of 80% and we feel that’s what Tech Armor’s main base is when it comes to their power capacities. They realize that conversion causes loss of power and they’ve optimized their power banks accordingly.

So with a conversion rate of 80%, this means that you’ll be getting about 16,640mAh of power capacity that you can use. It’s enough power that can place it well into the category of being a Samsung portable charger since most Samsung devices have large battery capacities.

Overall, it’s a power bank that is the best power bank for mobile smartphones since you can charge most smartphones about 6 times or more. As for tablets, this portable charger can very well be used with iPads and any other tablets.

A capacity this high makes this piece of tech go into the category of being a portable tablet charger. If you’re charging Mini versions of tablets like the iPad Mini 2 and 4, then you can expect about 2 full charges as long as you’re charging them alone.

If you’re charging higher capacity and full-sized tablets, then you can expect about 1 full charge. You must understand taking advantage of the entirety of the power capacity when you’re charging a tablet is important, otherwise, you’ll be receiving less than what you expect.

Output Charging:       Port 1: 5V2.1A    Port 2: 5V/1.0A

The usual case with a charger like this is that they’re supposed to be viewed as a superpower bank in a way because of their high power capacity. However, that’s not the case and this Tech Armor power bank falls into the same pitfall that other charging electronic companies fall into.

Okay, so the first port has a charging speed of 2.1 Amps and it’s with this port is that you’d use to charge your tablets and other higher Amperage charging devices.

With that said, the 2.1 Amps should be used with any of your devices regardless of if you’re charging a tablet with it.

This is because even smartphones can charge faster than 1 Amp, so the 2.1 Amp should be taken advantage of the most.

Then there’s the 1 Amp port and the logic here is that you’d use this port to charge smartphones and even though that makes sense on paper, it doesn’t make sense when you take into account that most smartphones charge faster than just a single Amp.

Especially those smartphones devices that are compatible with Quick Charge.

We don’t like this kind of powering design since the 1 Amp charging port is always going to be limited to that single Amperage speed since the other port doesn’t share its charging speed. If the current were open, then there wouldn’t be a compromise with power.

Input Charging: 5V/2.1A

The recharging speed is what it’s supposed to be with it being able to charge at a max charging speed of 2.1 Amps.

So if you’re using a 2.1 Amp wall charger or higher, then you can expect it to be fully recharged within 10-11 hours. If you’re singing a 1 Amp wall charger, then you could be waiting for a whole 24 hours for the power bank to fully recharge.

Design

Size and Weight

In this case, the power capacity and the charging capabilities are VERY directly related to the size and weight of the charger. This is not a good thing, though. The general rule with modern portable chargers is that even though they have high power capacities and a few charging ports, their sizes are still small.

This Tech Amor 20,000mAh power bank is 9 inches in length, it’s 4.9 inches in width, and 2.4 inches in thickness.

So it’s really large and long. The weight also matches the size with it being 12.3 ounces. Some may say this is what they expect from power banks that have these powering capabilities.

When you compare it to other portable chargers like the Anker 20100, or the Anker 26800mAh charges, then it’s clear that it doesn’t make itself compact enough.

This isn’t the kind of power bank that you’d walk around with, instead, you’d have to opt for setting it down and using it.

Functional Components

The functional components are very close together and are generally easy to use as well.

On the short side is where you can find the 2 USB Output charging ports, the Micro-USB Input port, the flashlight, and the power button. On top is where there are 4 LED Power capacity indicators.

The power button isn’t used very much since charging is automatically started when a device is connected to a USB charging output. The power button is mainly used to check the power capacity that’s left, and to turn on the flashlight by holding it down for 3 seconds.

Build

Structure and Material

For such a large power bank, we’re surprised by just how well the charger is built. It’s separated into 3 main pieces with a large centerpiece and has 2 side panels. The entirety of it is made of plastic and even so, it’s still able to hold strong even with daily use.

However, we don’t recommend dropping it. The power bank doesn’t have any/much safety to it and there’s nothing to take the shock damage from a fall.

Tech

On the tech side of things, the Tech Armor portable charger does well but there’s nothing out of the ordinary. We say this because it doesn’t take advantage of any special batteries like Panasonic battery cells or cooling tech.

However, it does have the usual safety tech like Surge and Short-Circuit Protection to make sure you and your devices are safe during charging.

Reliability

For the most part, this Tech Armor power bank is very reliable, although most of its reliability can be attributed to its high power capacity. For everything else, the reliability seems mediocre more than anything and this is the case since the portability isn’t a large factor with the power bank being very large and heavy.

As for the charging speed, that could be improved by having Amperage shared throughout its charging ports. The way the charging ports are currently designed makes it so that the 1 Amp port is always limited with its charging speed.

Summary

Power:

The power capacity with its conversion is good but it’s the charging speed that could use some work. The Amperage current should be shared, so there isn’t a compromise of charging speed when it comes to the Amp Port.

Design:

It’s a large power bank, and even for its power capacity, we still think it’s too large and heavy. With that said, it’s at least easy to use.

Build:

There’s nothing wrong with the build but then again, there’s nothing special about it. Just don’t drop it or else the portable charger may very well get damaged.

Reliability:

The reliability of this Tech Armor power bank could be better and all it has to boast about is its high power capacity.

Summary

It seems like the larger the size of the power bank, the more Tech Armor lost sight of what makes a truly great power bank. This isn’t to say that this charger is bad or anything but it lacks all the refinements that most portable chargers should have.
