Review: 2A wall/car dual chargers from iSmooth

Yep, it's the same iSmooth known for their screen protectors At first I was very skeptical because they are listed for Apple products, both dual port chargers with 2.1A and 1A - typical for iPad and iPhone/iPod devices. While talking to Paul, the guy behind iSmooth, he mentioned about using it to charge his Note 2 without any issues.
I got both of them, and can report they work perfectly with our Note 2. I can use either 2A or 1A ports to charge GN2 while still have other port used by another device, either android or apple. So functionally it definitely works. Another thing I noticed, 2A port charges the phone pretty fast, and when I connected iPod Touch to 1A port, the charge rate seems to be relative the same which suggests they don't share load where with some other chargers both ports are forced to 1A.
The construction of both is very solid, these are not cheap plastic chargers. Wall charger actually has substantial weight which suggest quality electrical components. Both have white/black theme, works with my UAG Navigator lol!!! Wall charger has a blue light indicator while car charger has a glowing blue ring. I tried capturing everything in picture details below. One thing that makes it unique, wall charger has a release latch to remove the electric plug. Once you do that, you have symmetrical 2-pin universal plug you can find on a ton of your devices around the house, like laptop ac-adapter or printer plugs. I actually used one from my laptop ac-adapter (not included with wall charger, obviously), but still a neat idea for extension cord. if your electrical outlet far away. But in general, wall plug is very slim and should fit without obstruct any other device plugged next to it.
The only drawback, wall charger is sold out on Amazon and I have been told it will take a few months before its back in stock. Oh, also forgot to mention - both wall and car charger come with 10 year free replacement guarantee. That is insane confidence of the product quality.
Ok, so here are the pics:

IMPRESSIONS
This charger blew the socks off my OEM charger. I got it when I had my HTC One M7 and the charger that came with that phone did an okay job - but it was more like a trickle charge. When using this charger, I was able to get a full charge from an almost drained battery in about 2 hours. And it was roughly the same time to charge both my wife's Samsung S4 and my M7 at the same time. :highfive:
This charger is great. It has two ports and it is has good build quality. I have been using it now for a few months and it is still going strong and charges my Nexus 6 great when I don't want to use the insanely fast turbo charger.
Not quite sure what the "Smart" port is for - the box did not come with a description on that.
RECOMMENDED
I would recommend anyone in search of a USB wall charger to purchase this product. I have used OEM chargers, and cheap replacement ones, and this one beats all the ones I've owned, hands down.

Will this work with a Kindle?

"Smart" USB chargers include solid state logic with serial communications chips. When you plug in a device that wants higher current, it sends a query to the power supply saying something to the effect of "I want 2 amps. Is that OK?" If the power supply is a dump USB port, it doesn't answer at all, so the device either doesn't work, or only draws the default 500 mA (and charges much more slowly.)

Compared to other charger i have reviewed in the past, this is interesting since it comes with 5V/1A USB ports too, useful to slow charge some devices.
The build quality is OK, nothing to complain about, there are no matte surfaces luckily and the plastic feels solid with no imperfections. Also, it is pretty compact and reasonably lightweight.
Unfortunately the amount of accessories included is quite limited, just a small manual and the Power Cord (EU in my case). I always prefer to see at least one USB cable included in any charger.
Talking about the power output instead, all tests have been made using my semi-professional USB Load + Tester.
Starting with the Quick Charge 3.0 port, this is working almost fine, and i say almost because it doesn't seem to reach 12V for some reason. At 5V though there are no issues in reaching 3A as rated.
The 5V/2.4A USB output is good enough, the voltage drops slightly at maximum rated load (4.91v) but perfectly acceptable. Increasing the load up to 3A (over the rated specs) causes the voltage to drop a lot, unusable for charging, but it doesn't trip the protection. Over 3A, it trips.
Finally the 5V/1A USB outputs. Both ports provide excellent voltage at 1A as rated, and you can squeeze up to 1.2A before tripping the protection.
Just to complete the review, here are the UGREEN 180 degrees Type-C Cables with 56k resistor. Do they work as well as the charger? The answer is, sort of.
Quality-wise they are decent, with nice colors and a semi-rubberized cable, but they tend to scratch a bit easily based on my usage (just like all rubberized surfaces). The rotated Type-C Plug is really useful though, all cables should be available in this format IMHO.
There is a 0.11A of loss compared to the direct connection, that is still OK for charging, but it won't handle 3A properly unless the charger pumps the voltage up over 5V, something that this UGREEN model doesn't so i recommend you to use those cables with another charger for 3A charging. BTW, UGREEN declares 22AWG for the power wires for those interested.
In conclusion, this charger is an interesting one with a decent power output and excellent build quality.

UGREEN USB-PD 30W Charger + Type-C Braided Cables - Unboxing and Review

After having tested the Quick Charge 3 chargers, it is time to test the USB-PD ones. This model in particular is the 30W variant with 1x Type-C Output.

Starting from the materials, the charger feels pretty solid with no glossy parts.
For best results, i have combined this charger with 2x Type-C to Type-C cables from the same brand, and the quality is excellent with a thick braided cable and metal shielded plugs. Unfortunately this charger doesn't include any Type-C cable.
Its power output looks to be as good as it should be, and my Essential Phone PH-1 was able to charge at lightning fast speeds with no issues. Unfortunately i am not able to show any voltage output for this because my USB Tester doesn't support USB-PD.
I am going to add more details about this test as soon as i get my hands on a new USB Tester.
As regards the Type-C cables instead, i am kinda disappointed. 4.62v for a 3A load is quite low, and this is the shorter variant. Basically, the thickness mentioned before is probably only due to the braiding and not to the internal wires (20AWG declared, i have some doubts about this). This test has been made using the Quick Charge Charger already tested previously. (link: https://forum.xda-developers.com/general/accessories/ugreen-4-ports-desktop-charger-quick-t3830526)
So, apparently this is a placebo, since again i can say that the charger is great thus i can recommend it, but i can't recommend any of those cables due to high resistance of them.

Nice review that u have but I think there's only a small users whose gonna buy this kind of charger

Can you help us by telling how much battery was charged in how many minutes and was that result obtained when you were using the phone (light usage like watching media etc) or switched off state or was it when screen was not lit?

[review] RavPower ultra-compact 45W PD GaN charger

RavPower reached out to me to see if I'd be interested in reviewing their new 45W gallium nitride (GaN) charger. If you haven't heard of GaN yet you'll likely be seeing it more and more as it's a newer tech that allows chargers to be smaller and more powerful. The only other on on the market right now is from Aukey, which is about the size of the OEM iPhone brick but can deliver 29W via PD. RavPower's offering is a bit larger and takes a different design approach, but ups the power to 45W making it suitable for charging devices like laptops as well as our phones. I'd read about it and seen pictures, but I didn't appreciate just how small it is until I actually got the unit.
Instead of a square brick RavPower's charger is more of a card design, with a folding plug that makes it very pocketable. At about 15mm thin the charger is insanely slim, and since the Type C Port sits at the bottom of the charger when plugged in this thing can fit behind some ridiculously tight spaces. This orientation may not always be ideal as it takes up a larger footprint along the wall, but in general I prefer it to a brick that sticks out far from the wall. The overall footprint is slightly smaller than a standard credit card. Like I said, I'd seen pictures of this before but was still blown away at just how small this charger was.
The charger uses power delivery to deliver up to 45W, and can output at 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/2.25A. Obviously the Pixels can only handle up to 18W but I also have a first gen Samsung Chromebook Plus and a Switch that can utilize the higher charging speeds. Using my USB C voltage tester I was able to confirm that the RavPower charged the Pixel 3 just as fast as the OEM Google brick (about 9V/1A) and it charged my Chromebook at 15V/2.25A.
This will be my new travel charger. It is so slim that it fits into any bag just fine and delivers enough power to charge both my laptop and phone at full speed. In fact, I just returned from vacation where it acted as my primary charger for two Chromebooks, two Pixels and a Switch. I'd love to see a dual port option so I could charge a few devices at once since this has enough power to charge two phones at full speed simultaneously. Still, as a first gen product this is quite impressive. I've used several RavPower chargers and battery banks throughout the years and never been disappointed; they have all been well designed and performed as expected. Even with high expectations, this charger has wowed me.

I hope this technology comes to battery packs soon. Those are getting way too big!
