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.)

Aukey Portable(ish) 10,000mAh External battery charger

Link to purchase: http://www.amazon.com/Aukey-10000mAh-Portable-External-Supported/dp/B011U0AY22/
I got this to unit to test and in exchange to share my personal experience with the external charger. When I was given the opportunity to review an external charger, I requested one that could perform quick charging on my wife's M8 and my Nexus6. And it happened that Aukey was looking on some people to review their newly released external chargers. I initially thought, "great! a new portable charger that's 10,000mAh! With certified Qualcomm quick charge 2.0 to boot!
When I received my unit, I immediately thought how thin it was but when I opened up the packaging, I was pretty excited for this for some reason. Maybe because this is the first charger I had that can be used without being plugged in to use Quick Charge? Possibly. In looking at the battery itself, it's a bit lighter than my other 4 year old 10,000 mAh portable battery, However, this Aukey has Quick Charge 2.0 AND a flashlight. LOL Well I never really understood the reasoning of adding flashlights to external/portable batteries. It's great to have during a power outtage, but that's it really. There is not other usages I can personally think of to use it in a everyday carry bag. Don't get me wrong, the matte finish all around warrants the relatively cheap price for a 10k battery, but my one gripe is that the battery is pretty long. It doesn't really easily fit into a pocket. You have to put this in a bag, no question. For me, I had to store it in my glove compartment until I needed to use it.
When initially charging it up, it uses a micro USB cord. A great thing because my other older 10k battery uses a proprietary cord/adapter combo to charge the 4 year old battery pack. Also I realized the "Aukey" label lights up and is colorized and based on the color represents the current battery level of the battery. I need to mention when not fully charged, the "Aukey" logo that is lit up, "breathes" while it's charging, making the sense that it's alive and resting or sleeping lol.
Would I recommend this portable(ish) battery pack with Qualcomm Quickcharge 2.0? YES for me. For 30 bux on Amazon, it's not bad, but if you are looking to stuff it in your pocket, look elsewhere. This is a laptop bag battery where you can charge up your tablets and phone at the same time and not worry about depleting the battery.
Pros
Black matte color is cool
Breathing logo is cool when charging
Flashlight (Pro AND Con?)
Moderately light
2.0 Quick charge capability
Uses Micro USB cord to charge
Cons:
Moderately heavy
Flashlight(?)
Too long to stuff in ones pocket. You need to ask your significant other to put it in their purses/bags.

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!
