[Galaxy S6 Edge+ Accessories] apurva.giri:
Tronsmart reached out to me a week back and asked me if I would like to review one of their new products and share my opinion with them. I liked the fact that they didn’t specifically ask me to write good things about the product or highlight only its pros, which many companies do when they offer you a free review product. I decided to do a detailed review of this product and give my honest opinion.

Two days later, I received this Qualcomm Quick Charge 2.0 Certified Tronsmart 54W 5-Port desktop charger (I know! That sounds great). It’s been 4 days since I’m constantly using this with my 5 different devices that need USB charging. Two of my cellphones (S6 Edge+ & Nexus 4), a ZenWatch, a BlueBuds X and a BlueSYNC Bluetooth Speaker (another review product).

Before I start with the review, let’s look at the product page here and see what really does this product claim to do ?

Here’s the list of features mentioned on their website:-

1.	Qualcomm Quick Charge 2.0 technology in one of the ports (distinguished by blue color)

2.	VoltIQ – Smart Circuit to identify the power level required for charging each connected device

3.	Backward Compatibility – Charge older smartphones which didn’t have high amp charging adapters

4.	54 Watts max output through 5-ports (not each)

5.	Ultra Compact

6.	Safety Guarantee – No Overcharging, No Overheating and Over Current protection

7.	18-Months worry free warranty

List of items received in the package:-

-	The desktop charger

-	A Power Cord

-	6 Feet USB Cable

-	A Cable tie

-	User Manual

Since we have set the base, let’s start the review..

It came in a nice and sleek cardboard package (probably recyclable), the content didn’t seem like shaking at all. The whole package was sealed with a plastic wrapper (which kind of makes the idea of recyclable box dumb). A paper seal would have made more sense here.

Here’s an overlook of the box (I’ve taken out the plastic wrapper already):-

Moving on, here are the contents of the box:-

Let’s be frank here. Nobody would actually trust their $900 brand new phone with a third party charger even if it’s a brand like Tronsmart. So, before I connecting this to my Galaxy S6 Edge+ and to make this review really worthwhile, I used this USB Current/Voltage Tester to check the power output of the product and compare it with my original charger. Usually less volt/amp wouldn’t harm your device but a higher power output may have an adverse effect if the device is unable to handle such high power. Even though I was pretty sure a product from brand like Tronsmart wouldn’t do such a thing, but better be safe than sorry… This tester is connected as an interface between the device (S6 Edge+) and the charger and displays power drawn by the connected device.

I connected the tester with my Edge+ and the genuine Samsung Adaptive Fast Charging Adapter. [Adaptive Fast Charging is almost equivalent to Quick Charge 2.0, only major difference being, Adaptive Fast Charging supports 5V and 9V adapters while the Quick Charge also supports 12V along with 5V and 9V. So, there’s the reason for my worry]. So, when connected to the genuine Samsung adapter, S6Edge+ was drawing 1.59Amp at 9.13V.

Next, I connected the tester between the Tronsmart Quick Charge port (Blue colored) and S6Edge+ and Edge+ was drawing 1.62 Amp at 9.00 V. Being a third party adapter, I didn’t really expect such accurate results. I know there is a marginal difference in voltage, but this kind of difference doesn’t matter at all.

Here's the image comparison:-

Galaxy S6 Edge+ can distinguish between a fast charger and a regular charger, so when I connected the Edge+ to a Tronsmart regular port, this is how Samsung tells you that its not utilizing the fast charging:-

Since I’m assured now that my S6 Edge+ is perfectly safe and compatible with this Tronsmart Desktop Charger, I wanted to move on to older devices which draws 1 Amp equivalent current and see if the charger’s VoltIQ detects and delivers the right amount of power. So, I connected my Nexus 4 to an Asus 1 Amp charger and recorded the readings as below: 0.87 Amp at 5.17V.

With Tronsmart Charger connected to the nexus 4, it was pretty amazing to see the following result:-

I didn’t stop there. Ofcourse my trust level has increased significantly on this charger, however, I wanted to go further with devices which draws extremely low current like my Asus ZenWatch and Jaybird BlueBuds X. And again, I was pretty amazed with the results because these devices, specifically my BlueBud X, draws extremely low current, like 0.01A (connected to laptop) and VoltIQ was able to detect just the right amount of Volt and Current for my device. Here’s the result from the test on my ZenWatch, BlueBud X and BlueSYNC Speakers respectively:-

I also verified that the readings are consistent even when all 5 devices are connected simultaneously.

Once I was totally satisfied with the output range it gives, I also wanted to verify the time it takes (the blue port) to charge my S6 Edge+ from 3% to 100%, so I ran a separate test. And again, result isn’t very different from what an actual Samsung Adaptive Fast charger claims to do. Here is the breakup of the charging time of S6 Edge+ from 3% to 100% :-

By now I should have, but I didn’t stop here either. I connected 5 devices to all 5 ports and have been doing the same for last 4 days to test if the charger heats up and trust me, it doesn’t even a bit. It’s been performing well and it stays cool. And it cleaned up the mess I had with 5 different charges connected to an extension.

Overall, I’m extremely pleased with this charger’s performance and the build quality definitely looks nice with good finishing. It doesn’t look like cheap plastic item at all. And I’m sure there’s no point in telling this since nobody would probably carry this in their daily bags, but this thing is really small. Look at the image below comparing it with credit card sized gift card.

Finally, here’s my pros and cons list for this item:-

Pros:

1.	Fast Charging with Qualcomm Quick Charge 2.0 Certification and compatibility with Samsung Adaptive Fast Charging

2.	Smart enough to detect all my device power limits - VoltIQ (this is what makes it useful)

3.	High Power output even in regular ports (helps charging high end smartphone devices faster which doesn’t support Qualcomm QC2.0 or Adaptive Fast Charging)

4.	No heat

5.	Very Compact

6.	18 Months Warranty (should be enough for the money you pay for this one)

Cons:-

1.	No LED to show charger is turned ON (personal preference)

2.	Only 1 USB Cable inside box

3.	Power Cord could have been longer

I know the cons section isn’t really applicable to everyone; it’s just my personal preference. However, if anybody asks me, I would definitely suggest this product in a heartbeat. It’s very cheap too. I know there are more such brands like Anker or Aukey, but I haven’t reviewed them, I reviewed this one and I’m totally satisfied.

Here’s a video review I created earlier:-

*Please note that the readings of the first day (when I made the video) and the day when I wrote the review aren't going to match accurately due to reasons like % of charging. However, the values are approximately same and the difference can easily ignored.
