There are plenty of underrated power banks that simply don’t get the attention that they deserve and that’s a shame.
These power banks match the quality of leading competitors or even surpass the quality of power banks that are already popular on the market.
It’s vital to know about these power banks because they provide immense hidden value that can assist with your charging needs.
The Tronsmart Presto power bank is such a power bank that delivers a strong charging experience that rivals other portable chargers, with its latest charging technology.
Other Types of USB-C Quick Charge Power Banks:
The Presto power bank has a power capacity of 10,400mAh but the real capacity of the power bank falls quite a bit shorter.
The real capacity that you’ll be getting stands at about 8,400mAh; Which is pretty good for a power bank of its size, but of course that’s 2,000mAh of missing power that could have been used towards charging a device for another round.
There are still other chargers that have worse energy conversion rates like the Xiaomi power bank, so we think that this kind of output capacity is quite manageable and acceptable.

Going into the charging aspects of the Presto power bank, it’s important to know that this portable charger is aiming for max charging.
What we mean by that is the power bank has a Quick Charge 3.0 USB output port and a USB Type-C port that is both an Input and Output. Both of the charging ports are capable of charging at 3 Amps speeds.
The Quick Charge USB output is able to charge either Quick Charge 2.0 and 3.0 devices at 5-6.5V/3.0A | 6.5V-9V/2A or 9V-12V/1.5A charging speed.
For non-Quick Charge devices, the charging speed can potentially be 5V2.4A, which can charge most other devices at their max charging speed.
Quick Charge Speeds: 5-6.5V/3.0A | 6.5V-9V/2A | 9V-12V/1.5A
The USB Type-C port’s output and input charging speed are 5V/3.0A. For the Type-C port to be used as an output port, you’re going to need to use a Type-C to Type-C charging cable, and this charging port is mainly for devices that use the Type-C input port for them to charge.
However, if you want to recharge the power bank you’re going to need a Type-C to USB-A 3.0 charging cable. The recharging speed of the power bank is 5V/3.0A and as a result, can recharge the power bank fully within 6-7 hours.
It’s a faster recharge speed than most power banks because many power banks settle for a recharge rate of 2 Amps or lower.
Overall, the Presto power bank is able to boast its powerful charging if you own a Quick Charge compatible device or if you’ve got a Type-C compatible device; This way, you can actually receive the blazing fast charging of 3 Amps.
For regular devices, the power bank is still able to offer fast charging but it’s very important to remember that you’re still going to need to a USB-C to USB-A 3.0 cable to recharge the power bank.
We think that the Presto power bank is a very explicit portable charger that holds a lot of charging potential but only if you’re using it with the right devices, otherwise, your experience with it can be mediocre.
Size and Weight
Sizing of this power bank isn’t all that bad. The length is 6.5 inches, the width is 3.4 inches and the thickness is 1.1 inches.
Putting it all together the Presto is a manageable enough power bank to hold in your hands until the weight of 10.4 ounces actually becomes difficult to hold.
The long length of the power bank highly contributes to the wall charger’s portability, since it’s stretched out, the power bank is able to be about 1 inch thick.
Not exactly pocket-friendly but if you’re taking the charger somewhere and don’t have a bag to put it in and don’t want to hold it in your hand, then it can be put into your pocket for short distance walks before it starts becoming cumbersome.
The power bank doesn’t have any sharp edges or protruding panels; Everything on the Presto charger is simply installed into the main body and it’s absolutely wonderful.
The two charging ports are on the small side strip of the power bank, the power button is on the long side strip and there are 4 LED power indicators that are on top of the power bank. The power button can be used to turn on the charger and to check the capacity of the power bank.
The Presto power bank is designed very objectively and because of that, there’s not much to say about it. It’s a power bank that you can simply pick up and take.
Its main purpose wasn’t to be as portable as possible and yet this moderately high capacity power bank is still able to be taken nearly anywhere and be used easily. Considering the capacity and charging speed that this charger is able to deliver, we’re impressed.

Material and Structure
The Presto power bank like many power bank is made of plastic. The structure of the charger has two main pieces.
There’s a top portion, where the button, LED lights and charging ports are; then there’s the bottom portion.
There aren’t significant signs of breakage or weakness within the construction of the two pieces. Most of the plastic on the power bank is varnished plastic, but there’s glossy plastic at the top of the charger; It’s definitely aesthetic feature and holds no protection purpose.
Ultimately, the Presto power bank’s physical build is on par with Tronsmart’s other products like their wall charger and car charger. They do focus on aesthetics but their build integrity is very strong and that’s what we honor them for.
The fast charging power bank does have loads of safety tech features that make the charger safe even if you’re using the total output of 6 Amps.
Charging speed may decrease if the power bank begins to generate too much heat since 3 Amps of current can generate quite a lot heat, but the decrease of the charging speed isn’t something to be disappointed about since it’s a way to keep your device and the Presto power bank safe.
The charger can even turn off if it becomes too hot and this can be frustrating because you may not be paying attention to your smartphone charging and as a result, your phone could just be sitting there a not charging; meanwhile you’re thinking that it is charging.
We wish that there was a way that the power bank somehow notified the user that the power bank stopped charging their smartphone so they could turn the power bank back on and resume charging.
So the safety features can actually get in the way of the charging experience but Tronsmart has implemented plenty of features to maintain a safe charging environment.
Tronsmart has once again built a charging electronic that delivers on what it promises.
Yeah, we know the power bank does have 2,000mAh less than what its stated power capacity is, but it’s still able to charge smartphones 2 times or more.
If you really want to charge an iPad using the Presto power bank, then we recommend taking advantage of the entirety of the power capacity.
Charging-wise, the power bank is really meant for devices that are either Quick Charge compatible or USB Type-C compatible and that’s where the most reliance of this power bank falls into.
If you’ve got a smartphone that has either QC or Type-C then you can charge your phone at 3 Amps, which is really fast charging.
If you’re using a smartphone without QC or Type-C then you’ll be relying on normal charging at 5V/2.4A; Additionally, you’ll have to own a Type-C charging cable to recharge the power bank.
So for those with smartphones that don’t support Quick Charge tech or Type-C charging, can have limits for what it will offer you. However, if you have either of those types of smartphones, then you can take full advantage of the charger.
Portable and design side of things go hand in hand, with the Presto being able to deliver a stable safe charging experience that can potentially be taken anywhere.
The power capacity is pretty good with what it offers, as it does well with charging most smartphones at least two times.
The charging speed is the most powerful aspect of this power bank because both of the charging ports are capable of charging at 3 Amps speed by utilizing Quick Charge 3.0 and Type-C. Even the recharge speed of the Presto power bank is done at 3 Amps.
Although it’s still quite big, the power bank is manageable enough that you can hold it comfortably while walking and in rare cases, you can even put the Presto power bank into your pocket; but that’s really the last resort for portability.
The charger has a very objective design with all the functional things on the charger on the side and there’s no protruding space on the charger.
It’s a solid build structure with the power bank having only two pieces that come together to make it whole.
The power bank may be plastic but there’s nothing bad about the way it’s used and it’s light varnish makes it good to hold.
The Presto is full of safety tech but the most notable is the temperature control that can turn off the power bank if it gets too hot and is very helpful to prevent the power bank and your device from getting damaged.
This power bank is definitely reliable but it has a range of when it can be relied upon its full potential and when it’s reliable to a certain extent.
For a Type-C device that uses Quick Charge tech, this power bank is going to be very reliable because the user will able to take advantage of fast 3 Amp charging.
However, a device without Type-C or Quick Charge compatibility isn’t going to take much away from this power bank. Also, it’s important to remember that you need a Type-C cable to recharge this power bank.

It can offer the fastest charging experience along with its other strong attributes of being built well and with a sleek design.
For those without the two main charging technologies, I recommend going for a more standardized power bank with an output charging speed of 5V/2.4A.
