Tronsmart is a most popular manufactory in mobile phone accessories, especial in certified Quick Charge 2.0 charger. I have already tested one charger from them before, but now, they have just released more chargers with more powerful features which you can’t resist.
In this short test I will test Tronsmart WC2F which features 2 quick charge 2.0 port for fast charging 2 devices at the same time, both port can reach maximum of 15V/1.5A each.
You can check out more features, including where you can buy this amazing charger from their official website at: http://www.tronsmart.com/products/tronsmart-wc2f-36w-dual-ports-usb-wall-charger-black

There is not much to talk about the packaging, it’s simple and environment friendly. At the back of the package, we can find their company address, phone number and email for support.
Inside the package, we will have a charger, 2 USB cables, 1 manual, 1 VoltIQ sticker.
Here are our charger, naked.
Yes, there is also a manual for a charger, in case you don’t know how to charge your devices, you can open this manual, they will show you.
Let’s take a closer look at the charger. At the front of the charger, we can find Tronsmart logo, a small indicator light.
At the back, we can find the charger specifications, as we can see, it can charge at 5V/2.4A, 9V/2A, 15V/1.5A for each ports.
More fancy images
Let’s do the test, I will use a usb detector to monitor the charger voltage and ampere, this detector can monitor up to 9V/5A, and I will use my Zenfone 2 to test this charger which can charge maximum at 9V/2A so I think the detector will survive.
More fancy images
I will charge my phone from 10% to 100%, and monitor via Asus stopwatch app, as for new software update, Asus has changed how fast charge works, they will limit the ampere to 0.83A when the screen is on, and can only charge at maximum when the screen is off.
It took about 1 hour and 45 minutes to completely charged Zenfone from 10% to 100%, the phone itself would limit the ampere to 0.35A when it reached 90% so we could charge faster with full ampere.
So here are some pictures of the test.
Let's get started.
The phone is increasing the ampere when the screen is off.
It took 6 mins to charged 16%.
10 minutes to 22%.
23 minutes to 39%.
35 minutes to 52%.
54 minutes to 75%.
From this time, my phone was limited the ampere to normal charging, which took more time to fully charged. It took 1 hour 25 minutes to reach 93%.
1 hours 30 minutes to reach 96%.
And finally, the phone phone was fully charged in 1 hour and 45 minutes.
Conclusion
This is a great fast charger with a great build quality, solid USB cable for long time usage, build-in 2 quick charge 2.0 ports so you can charge 2 devices at the same time.
The only disadvantage from the charger is the temperature when you charge 2 devices at the same time, it’s really hot, I don’t have any device to monitor the temperature, but it was very hot when I touch the charger.
For the price of $21.99 USD, this is the best charger in its price range and a good alternative for original Asus BoostMaster charger which costs about $29.99 USD. You can buy this charger at.

Hello, I just want to know whether this charger is backwards compatible. Means if I have phone with no quick charge, 5v 2A input will it work..??
Regards

I'm more interested in that voltage ampere indicator/detector
Where can I buy that?

Tronsmart Titan: The best charger for your home and smart devices.

Quick Charge 2.0 becomes the standard for charger nowaday, and Tronsmart got a charger with 5 QC 2.0 ports (18W each port and 90W in total output), that is a huge charger and they named it “Titan”.
This is the best charger I’ve ever used as it comes with five QC 2.0 ports which can charge 5 devices at the same time, it got a solid build and even with 5 devices charging at the same time, there is still no heat (even their old QC 2.0 products still generated a lot of heat when charging).
Here is same tech spec I took from their website:
Powerful:Total 90W for 5 ports, 18W for each port. The most powerful desktop USB charger for family and office use ever.
Featured with the latest 2 in 1 charging chip. Design both Qualcomm Quick Charge 2.0 and smart detective technology in one chip.
Safety guarantee. Built with industry grade materials and premium circuitry, fully protect against over-current, overcharging and overheating for safe and fast charging.
That looks very promisely, if you still curious about this “Titan” you can took a look at: http://www.tronsmart.com/products/tronsmart-uc5f-90w-5-ports-usb-desktop-charger (You can also find where to buy it online here too).
1. The box.
The package is simple, white box with some details on it.

In the front of the box, we can find the product name, model and its picture.
At the back of the box, we can find more informations here, we got their address, mail and phone number. Some useless copyright informations too.
Inside the box, the charger took 3/5 of the box inside, leave a small place for AC cable, sadly, there is no USB cable for this “Titan”, it would be more great if they could give us 5 USB cable for the “Titan”.
Here is our “Titan” stand alone.
Unlike other Tronsmart chargers, there is no manual too, but we got 2 stickers inside the box.
2. The charger.
Front with the Tronsmart logo.
Back with some detail, tech spec.
Here is our 5 QC 2.0 ports, those ports are solid built.
We got a on/off switch and AC port.
Small indicator light at the corner.
Here is the AC cable
Some fancy picutres of the "Titan"
3. Quick test with Zenfone 2:
As usual, I will start charging from 10% with my Zenfone 2, I will use Stop watch on Zenfone to count the time, it's displayed as small text on lock screen.
It took 7 minutes 27 seconds to reach 20%.
It took 20 minutes 15 seconds to reach 35%.
It took 30 minutes 03 seconds to reach 46%.
It took 53 minutes 31 seconds to reach 75%. The phone is charing at normal speed to extend the battery life, this is ASUS Zenfone 2 feature?
It took 1 hour 2 minutes 24 seconds to reach 81%.
It took 1 hour 16 minutes 14 seconds to reach 91%.
It took 1 hour 30 minutes 14 seconds to reach 95%. The phone is lowering the charging speed to extend the battery life.
It took 1 hour 44 minutes 01 seconds to fully charged our phone.
4. Conclusion.
This is the great charger I've ever used, it won't heat even with 5 devices charging at the same time, and it's cheap. I recommend to buy this charger.

Tronsmart Is a good brand, several weeks ago I bought one charger of this brand the model that have only two USb ports and it is excellent for a fast charging I recommend this brand.

Great review, thanks for the tip. Btw the slower charging above 75% is natural with batteries due to the design. They charge very quickly in the bottom half of their capacity but as they approach full the chemical reactions slow basically because there's less room for the electrons to move about (simplest explanation). I'm no expert, just took a few engineering classes in college. It would be cool if they made this charger with wireless on the top, but that would make it a lot more expensive probably.

I have a different version of this. I've never really used it tho haha

Charging speeds with Ampere

I recently bought this dual USB A and C charger (http://amzn.com/B019C23ZGW) to charge my 6P and N7 while on the road. However, it only will charge my N7 at a max of 350 amps.
I contacted the company and they said its a problem with my tablet. They are sending me a replacement but I won't be able to try that any time soon. So I was wondering what others are getting on their N7 with whatever charger they are using?
I am currently travelling and can't test with any other chargers since I only brought the Tronsmart.
App used for testing.

Thanks for any input!

weird but here it depend of the cable. Some cable would charge at 750 while others charge at 590. I've bought 2 meters long flat cable, it's the worst at 360. So with the same 2 amp asus charger i get different result depending of the cable i use.

wait, now it says 310 via my usb cable wtf?

USB cable and Qi wireless charger both indicate around 500mA with the program on my Nexus 7 2013.
Measurements from the USB meter feeding the cable reads 5.09V @ 1.03A with the Qi charger and 4.89V @ 690ma when using the USB directly.

Thanks for the good info. I appreciate it.
I guess this old tablet like to hover around 500 mA

Hitting 490 mA with a random charger and cable I picked up off my floor so you'd hope you could do better than 350 with brand new gear. (Using ElementalX kernel with fast charge disabled)

Tronsmart Presto: The new 12000 mAh Quick charge 3.0 powerbank

Our new smartphone is more powerful everyday, but we just can’t put a big battery in a small and slim device, so they invented PowerBank.
Tronsmart is one of the first manufacturer to introduce Quick charge 3.0 PowerBank, they named it “Presto”, it’s powered by 12000 mAh battery which can charge up to 4 times for our Zenfone 2. Sadly, this powe rbank supports QC 3.0 but our device can only charge with QC 2.0.
Tronsmart Presto Specifications:
Qualcomm Quick Charge 3.0: Up to 4x faster than standard chargers, able to charge compatible devices to 80% in just 35 minutes. Backwards compatible with all versions of Qualcomm Quick Charge.
Type-C Input and Output: Use it to quickly recharge the 12000mah external battery, or to power your Nexus 6p/5x with USB-C/Type-C ports.
Remarkably Compact: Much smaller than other high-capacity portable chargers. No other charger packs this many recharges at such high speed into such a small space.
Stylish, Practical & Safe: Smooth ebony varnish with 4-LED battery level indicator, 100% safe circuit protection; charger automatically shuts down if short circuit or overload occurs to protect your devices.
You can check out more information and the price at: https://www.amazon.com/Tronsmart-Pr...d=1466731576&sr=8-3&keywords=tronsmart+presto
What You Get in the box: Tronsmart Quick Charge 3.0 12000mAh power bank, 30cm USB-C to USB-A cable, welcome guide, our worry-free 18-month warranty and friendly customer service.

2. Tronsmart Presto Power Bank:
The power bank is made from all plastic, with black color and solid build. I really like this over Xiaomi Power Bank because the Mi Powerbank is easy to get dirty as there is a lot of dust in my place.
On the front of the Tronsmart Presto power bank, you will see a Tronsmart logo and 4 stylist battery level indicator white LED.​
On the back, you will see some technical informations about the output and input of the power bank. Here is a closer look:​
On the top, there are two port, the USB 3.0 port is for output only, but the USB-C port you can use it for both output and input (to charge your devices or to charge your powerbank).
The power bank comes with one 30cm length USB-C and USB 3.0 cable, the cable is solid too.​
On the side, you can find the power button, you have to put it to power on the Tronsmart Presto before use (not like Mi Powerbank, you just put the device in and it will automatic charge your device!).
3. Charging Zenfone 2 with Tronsmart Presto.
I’m using Zenfone 2 with Anker cable to test Tronsmart Presto power because Zenfone 2 doesn’t support USB-C.​
I started charge the device from 3%, and it took 10 minutes to charge from 3% to 17%.​
I got 20% in 13 minutes. There is not much heat as QC 2.0 charger.​
I got 41% in 29 minutes.
​
I got 58% in 42 minutes.​
I got 79% in 1 hours and 2 minutes, the phone is now charging at normal mode to extend the battery life.​
I got 89% in 1 hours and 16 minutes.​
The phone is now fully charged at 1 hours and 48 minutes.​
4. Summary
Pros
Solid build.
One of the first QC 3.0 compatible power bank for fastest charging speed.
Not much heat generated while charging.
Cons
Not much accessories.
A bit boring design.

Thanks for the review!

Max charging rate for Galaxy Fold?

Just bought the Galaxy Fold (coming in the mail) but I'm confused on what is the max charging rate for the Galaxy Fold. I know the included charger is 15w but upon some research I'm getting mix answers. Some reports say 15w is max and other reports are saying 25w is capable if you get the right charger.
Can anyone chime in?
PS. I did look at the official specs on Samsung's website and a lot of the info are inconsistent.
Thanks

I cant remember what the note 10+ charger was but that charges phone in like an hour 30 from 0 to 100 1 hour 50 not used the fold charger lol also have a Qualcomm 2.0 charger that takes 1 hour 30 to 40 prob 2 hours from 0 to 100

So, I just did a test.
I have 3 chargers here. A 25w Samsung charger from my note 10+, a Razr Quick charge 4+ and the Samsung 15w charger that came with the fold.
Fold is currently at 33%. When I plugged in the 3 different chargers the time showed on screen till charging is complete was:
25w Samsung: 1 hr 10 mins
Razr QC4+: 1 hr 10 mins
15w Fold Charger: 1 hr 28 mins
So it would look like the fold does use a bit of extra charge that the 25w and quick charge 4+ provides and is not limited to only 15w. I don't think it's using the full 25w though, as the note 10+ had a 4300mah battery and charged in 58 minutes in comparison to the extra 15 mins it takes on the fold.
Good to know though.

Double post whoops..

I went ahead and bought the 15w wireless charging stand since the Fold supports 15w wireless charging officially and it came with the same charger as the note (25w and I am assuming to charge the phone + built in fan)
Here are my results using the Ampere app (by no means this is a scientific test):
