The iPhone 7 is Apple’s latest iPhone and it’s also the most strange one and that’s because it doesn’t use a headphone jack.

Sure, it’s now known that the iPhone 7 indeed no longer uses a headphone jack and even though there are tons of people that dislike that, it’s Apple’s goal to make a portless smartphone. That said, if one thing hasn’t changed too much, it’s that the iPhone battery capacity has basically stayed the same.

One of the best solutions to having more power to use with your iPhone 7 is using a portable charger.

That said, as popular and useful as portable chargers are it’s another device that you would have to hold at the same time as your smartphone.

The other solution is to use a battery case and it’s a better option as it’s a portable charger that has taken the shape of a case and therefore you’re able to charge your iPhone 7 while you have a case on rather than a totally separate object.

That is why we’ve done a review on this Trianium iPhone 7 battery case as Trianium is one of the most popular brands that creates battery cases for an array of smartphones on the market.

Power

Power Capacity:

The power capacity of most battery cases is that of a Mini portable charger and it makes sense that they have that much power as they’re in the shape of a case.

The use of a low power capacity with this battery case is definitely present as there’s 3,200mAh of initial power available to you. It’s a great power capacity for the iPhone 7, not because you’re able to use it all, in fact, you’re not going to be using the full amount of the 3,200mAh power capacity as power is lost during charging.

3.7 x 3,200 = 11,840 / 5 = 2,368

Overall, you’re able to use about 2,368mAh of Output power capacity towards charging your iPhone 7 and that’s really good.

You might be wondering what’s so good about not having the full power of the capacity available to you, well the initial power capacity is high enough so that you have enough power to actually use.

In this case, the Output power capacity is enough to charge your iPhone 7 to its full power at least once and you can still have left over power to charge for later.

So, it’s not really about having a high power capacity when it comes to battery cases and basically portable chargers in general. It’s more about having enough initial power capacity so that you have enough power to charge your phone to full power after it’s been converted during charging.

Output Charging:

Perhaps the weakest part of this battery case is its charging speed as it has an Output speed of 5V/1.0A.

Most battery cases tend to have at least a speed of 5V/1.5 or higher than that. In this case, it would have been better to have a slightly faster-charging rate as the max charging speed of the iPhone 7 is 2 Amps and going a little beyond the single amp charging threshold would have made a better charging experience.

Also, the iPhone isn’t even compatible with Quick Charge, and therefore this Trianium battery case charges your smartphone at half its max charging speed only.

That said, we shouldn’t be too harsh to judge its charging speed as you’re purchasing a battery case because of the power that it refills to your smartphone, not really the charging speed.

Input Charging:

The input charging speed for recharging the battery case is the same as the output which is 5V/1.0A. It’s not all too surprising as most mini portable chargers tend to have a recharge speed of 5V/1.0A and this battery case is no different.

This Trianium battery case uses a Micro-USB input port for recharging and you’re also able to sync and share files with your iPhone and a computer while the case is on.

Design

Size and Weight:

A battery case is bulky and adds weight to your smartphone, that is a simple truth that everyone that wishes to purchase a battery case needs to understand. They’re not like your regular case that doesn’t have a power capacity. As they have circuitry and batteries within them.

This Trianium battery case with its relatively low power capacity in comparison to other battery cases that have higher power capacities is actually quite small. That’s because it has a length of 5.9 inches, a width of 2.7 inches and its thickness of 0.4 inches. The weight of the battery case is 2 ounces.

Overall, in terms of being a battery case, it does a great job at being as slim and lightweight as possible so that you have the least amount of hassle with it.

Functional Components:

The functional parts of this battery case are quite standard and are basically the same as other battery cases.

That’s because it has a large cut-out at the back of the camera, also at the back is where there’s a power button and 4 LED power capacity indicators. At the bottom is where there’s a Micro-USB input port for recharging the battery case and sharing files too.

However, the use of a Micro-USB input rather than a Lightning input port seems like a poor choice and that’s because this battery case is for iPhone users and therefore they’re going to be using Lightning cables the most.

Also, you’re able to recharge the battery case and charge your iPhone 7 at the same time, but the use of a Lightning cable would have made it better as it would be just like charging your iPhone 7 directly.

Build

Structure and Material:

There are two main portions of the battery case. There’s the battery case portion that has the battery, Lightning cable stem, and all of the functional parts.

Then there’s the double injected bumper that provides the rest of the protection and that actually makes up the whole case. The best part of the bumper is that it actually provides protection to your screen and therefore you’re able to drop it and not be worried about your screen getting damaged.

Tech:

On the tech side, the use of a slow charging speed definitely has its benefits and that’s because the battery case doesn’t even heat up during charging.

Reliability

In basically all of its aspects, this battery case is very reliable. The reliability comes from its power capacity that’s able to charge the iPhone 7 to its full power once, it has a slim form factor than most other battery cases and it provides full protection for your iPhone 7 too.

The unreliable parts are its 1 Amp charging speed and that it uses a Micro-USB input port rather than a Lightning input.

Summary:

Power:

There’s enough power to charge an iPhone 7 to its full power at least once and you’re also able to recharge the battery case while still charging your iPhone 7 at the same time.

Design:

In general, battery cases are big and add weight to your smartphone. This one does but at a smaller degree.

Build:

Build quality is great as the battery case provides full protection for your iPhone 7 and that includes protection for your screen.

Reliability:

It has a great level of reliability with all of its parts put together, it just would have been nice to have a Lightning input port, but we think that the use of a Micro-USB input port was because it was easier for installation and the tech is easier to work with.
