Battery cases are quite a lot less used than power banks and that can be surprising while at the same time it makes sense.

Since in comparison to just plain cases, they’re a lot thicker and they weigh more.

But at the same time battery cases are just power banks but in the shape of the smartphone that you’re using them for, as a result, they’re a lot easier to travel with as they’re just going on your smartphone and you don’t have to worry about carrying around a completely separate device.

This Trianium battery case for the iPhone X packs a large 4,000mAh capacity and it makes sense to have either a power bank or a battery case on this new iPhone from Apple.

As the iPhone X uses a lot of power if you’re someone that uses it constantly and you can’t be surprised that it’s going to be low on power throughout half your day.

So let’s see if this battery case is a better choice than a power bank, or if you should be getting more of a dedicated portable charger that features more.

Power

Power Capacity:

The power capacity when it comes to battery cases is that of mini power banks and this isn’t a bad thing, and neither should it come as a surprise.

That’s because these cases are very small and have to be as small as possible. Of course, there are battery cases that don’t exactly care about being the smallest such as ZeroLemon’s battery cases.

This Trianium battery case has a 4,000mAh power capacity and this is a lot of power, even when you take out the capacity that’s lost during charging.

So let’s first calculate the output capacity that you’re able to use to charge your iPhone X.

3.7 x 4,000 = 14800 / 5 = 2,960

So the capacity that you’re going to be able to use if 2,960mAh or 3,000mAh if you want to put it into simpler terms.

This is very good as the iPhone X has a battery capacity of 2,716mAh, so this Trianium battery case can charge the iPhone X to its full power only one time, and then it’s going to require a recharge.

So if you’re someone that actually has power with their iPhone X at the end of the day, and doesn’t put their smartphone on charge overnight.

Then you’ve still got a fully charged battery around your iPhone X that’s ready to charge it to full power.

Output Charging:

Charging with most battery cases is very slow, and this Trianium battery is no different and that’s because it has a charging output speed of 5V/1.0A.

So don’t expect fast charging speeds with this battery case, as one of the fastest charging speeds that you can use with your iPhone X is USB-C Power Delivery.

It’s understandable that most battery cases, including this one, have slow charging speeds too since they’re cases that envelope your entire smartphone and so heating up of the battery case can be quite bad.

Input Charging:

When it comes to recharging this battery case, it uses a Micro-USB input port that has a recharge rate of 5V/1.0A.

So it doesn’t matter what USB wall charger you use to recharge it at most wall chargers on the market at this point have standard charging rates of 2.4A with each of their ports.

Also, this battery case does not feature wireless charging, but there are battery cases that can recharge wirelessly such as Alpatronix’s battery case.

Design

Size and Weight:

A very important part of a battery case before you purchase one is that you have to be prepared for the larger size, thickness, and weight in comparison to just normal cases.

As battery cases, actually have a battery inside of them, and circuitry to carry out charging. In this case, this Trianium battery case has a length of 6 inches, a width of 2.9 inches, and a thickness of 0.5 inches.

The weight of the case is 6.1 Ounces.

So it will add some thickness to your iPhone X as well as some weight too.

So having this battery case on your smartphone and placing it into your pocket will feel quite a bit different due to the larger sizes.

Functional Components:

Using this battery case is quite simple.

Two main pieces make the case up and that would be the actual battery part and then there’s a snap-on front piece to keep your smartphone in place and adds protection too.

Placing the piece on to the battery case part is quite easy but taking it off can be a challenge and you’re going to need a pretty good tool that can get in between the case to take it off so you can take your iPhone X out.

Using the battery case to charge your iPhone X is done by just pressing the power button at the back of the case and there are also 4 White LED power capacity lights.

At the bottom of the battery case is where there’s the Micro-USB input port that’s used to recharge the power bank.

The cut-outs, in this case, are all accurate and respond well to when you press the buttons.

Build

Structure and Material:

Even though this battery case does have protection properties, it doesn’t have full protection for your smartphone.

The case is meant to be protective for the iPhone from the back, the sides, and the corner.

That said, the bezel with this case is not large enough that it can protect the screen and that can be a large flaw if you’re someone that’s looking for a battery case to charge your smartphone while at the same time want one that protects it too.

Tech:

Since the charging speed of this battery case is quite slow, it doesn’t overheat.

Reliability

The power capacity is the main part of a battery case, and it supplies enough power to be able to charge the iPhone X to its full power about once.

Charging speed is slow, but that’s what most battery cases feature anyway.

That said, the case does not feature Wireless recharging, and that’s something that we expect from a battery case for the iPhone X, as the iPhone X is capable of Qi wireless charging.

Summary:

Power:

Charging power is good with it having enough power capacity to charge the iPhone X to full power at least once. There is no wireless recharging for the battery case though.

Design:

It’s very easy to use case with just the press of a button that allows you to be able to begin charging, The front part that connects to the battery case portion is easy to put on but difficult to take off.

Build:

It does add protection to your iPhone X but not full protection because it doesn’t save the screen from a full-frontal face fall.

Reliability:

It’s a very reliable battery case, no matter how you look at it, with its 4,000mAh power capacity.
