Just a quick question about External Batteries

I'm about to buy one of the i9300 compatible external batteries, such as the Anker Astro 2, Anker Astro 3 or one of the Powergen brand (The 12000 mAh one looks AWESOME). But before I do that, I was wondering if the charge ratio from this kind of batteries to the device is similar to the PC USB (Which takes forever) or the AC charger (That would be very nice).
The aim is to avoid running out of power in a long trip with heavy use of the device.
Anyone of you have experience with this kind of stuff? any recommendations?
Thanks for your time guys.

It should be similar to the charge rate of the wall charger. The astro3 has dual 5v 2A outputs and the astro2 has a 5v 1A and a 5v 2A output. The stock wall wart outputs 5v 1A.

I recently bought this for traveling:
Anker® Astro3E Mobile Battery Pack 10000mAh
I'm very happy with it, the charging is fast and the capacity seems to be as advertised. Not too big, and even looks pretty nice

Big difference in charge speed between usb car chargers

I've tested two different car chargers, charging the Galaxy S4 at low battery in the car:
Energizer CC15141: 460 mA
Cheap dual usb ipad charger: 1200 mA
The dual usb for ipad allows up to 3.1 A top one or two at the same time.
The Energizer is up to 1 A
I guess the dual usb for ipad emulates wall charger, while the energizer does not, so the difference in charge speed.

Wall charger and USB cable?

Hi All,
I'm looking to buy an after market wall charges as the one that came with my Moto X died a couple of weeks back. Charging through the USB while will slow down the degradation of my battery takes forever. And a longer USB cable would also be nice.
Any recommendations? Right now I'm thinking of getting the RavPower 36W 4-Port for the charger.
(And is this the right section to be posting this? Or should I have made the thread over at Q&A?)
Thank you.

@kyzn
I bought my phone on Swappa and it didn't come with a charger. My only suggestion I have is to either get the Motorola Turbo Charger, or get one of their regular dual-port ones which you can purchase directly off their website. Sorry that I don't have a better solution or answer.

Why 36w when there's a 50w available?

I'm using this charger -> Anker® 40W 5-Port High Speed Desktop USB Charger with PowerIQ Technology
And these cables -> Anker® [3-Pack] Premium 3ft Micro USB Cables High Speed USB 2.0 A Male to Micro B
It also charges my iPads (using their own cables), and other devices (digital camera, bluetooth headsets, Anker External battery, etc). And i bought one of those for charging my son's RC trucks and Zoomer Dino.

I only have my phone to charge. Seems like a waste of ports.

Ok, then this -> Anker® 20W 2-Port USB Wall Charger with Foldable Plug Puts out up to 2.4A per port, up to a total of 4A.
Or -> Anker USB Rapid Wall Charger Its only a 1amp which is fine for most phones, like the 2013 X. My X came with a Moto 1150mA (1.15A) "duo rapid charger." So this 1A Anker will take just slightly longer to charge the X, but really shouldn't be that noticeable.
use either of them, with the cables I suggested before. Or this -> Anker® 6ft / 1.8m Extra Long Premium Micro USB to USB Cable High Speed USB 2.0 A Male to Micro B
(yeah, I'm happy with my Aker products, but no, I'm not employed or otherwise associated with them)

@KidJoe Thank you for the help. I ordered the Anker 20W 2-port and the 6ft USB cable.

Did you try calling them? They have pretty good customer service, if it died they might just send you another one for free.

The Best Quick Charge 3.0 Single Port Wall Charger | Anker vs Aukey vs Tronsmart

hi guys
i want to buy a Single Port Wall Charger
which one has a better built quality from your experience ?
1- AUKEY PA-T9 18W USB Wall Charger Compatible with Qualcomm Quick Charge 3.0
Amazon
2-Tronsmart WC1T 18W Quick Charge 3.0 USB Wall Charger
Amazon
3-Anker PowerPort+ 1 Quick Charge 3.0 18W USB Wall Charger
Amazon
from the pictures(i think) it seems aukey has a better board quality than anker but i could'nt find any pictures of Tronsmart WC1T board
base price for both anker and aukey is about 40$ and for tronsmart is 25$ so maybe those two have a better build quality
but some reviews about other tronsmart products says that chargers from this company have a better quality in material (housing plastic) than aukey or other
which one do you prefer?

I think Tronsmart is better.
I was thinking about buying a Qualcomm QuickCharger and researched it a lot. I chose the Tronsmart charger over the Anker Powerport singleport wall charger.
Pro's:
1. Comes with a USB cable (24 AWG) with a length of 6 ft. (I wanted a long USB cable with good charging rates! For Quickcharging, a good cable is a must along with the QuickCharge adapter)
2. It comes with an Indian type plug (I am from India, and didnt wana buy a converter for USA to India conversion)
3. footprint is similar to Anker
Cons :
1. No LED light (In Anker, blue light normally; green when in 9V/12V. However, once you have established that your device supports Quickcharge, the colour change has no significance)
Good luck. Also let me know which one you bought.

any other thoughts?
which one do you think has a better build and board quality?

They are all GOOD, and possibly made in the same place in China. Not familiar with Transmart, but I have reviewed a ton of Anker and Aukey, and Choetech products. They all good because they have a better quality control and offer an excellent support and extended warranty. To differentiate, maybe look for better accessories, like low gauge cables (that's a plus for high current charging), and better price deals.
Btw, what are you planning to charge with QC3.0, are there any phones/tablets even available to take advantage of it?

Anker makes a quality product. I know their batteries work well. I'd go with them over the others.

I also trust Anker's quality. But I could think twice when purchasing since its price is always highest one.
Anker, Aukey and Tronsmart quick chargers all comes with 18W output. Actually the 1st release of this products share the same specifications.
So the quality is the point. It is very difficult to decide based on their Amazon reviews, almost the same review rating.
So, I am iClever Fans, since I bought a dual usb charger from their store. Works so great as I expect.
Its quick charge 3.0 single port charger is Amazing, 24W output.
Wow, Seems like the seller is providing deal price at 13.59$.

Ii would prefer aukey, I bought aukey qc 3.0 for use in car, and it works very well, I got some hdmi miracast adapter from Tronsmart and there is poor support on it, and does not work well (cant connect from NB or PC with Windows 10 to the adapter, but from smarthphone it works, only sometimes drops connection)

I have my HTC M10 on hand now. Just buy a set of QC 3.0 charger(wall, car, desktop) from Tronsmart. Works as expected.

if you want a cheap options the Aukey PA-Y2 blows the competitions away.
https://www.aukey.com/products/amp-type-c-dual-port-wall-chargerwith-quick-charge-3-0
this is the only charger that can fast charge both USB Type A devices and Type C devices.
Type C devices like Galaxy S8, Nexus 5X/6P or Google Pixel aren't able to be fast charged using a type a to type c cable, so please consider it when getting a type a only charger.

Review: Auckly 10000 mAh USB-C powerbank

I recently recieved my Auckly W126 10000 mAh powerbank and wrote this short review from the perspective of a Google Pixel 2 XL owner.
Disclaimer: I purchased this item for the full price at Amazon. I am not related to the manufacturer and did not receive any incentive for the review.
Specs
capacity: 10000mAh
ports: 4 (USB-C in/out, Micro-USB in, USB-A QuickCharge out, USB-A out)
Micro-USB in: DC 5V-2A max
USB-C in: DC 5V-2.4A 9V-2A 12V-1.5A 18W Max (supports both USB-C to USB-C recharging powerbank and charging device)
USB-C out: DC 5V-2.4A 9V-2A 12V-1.5A 18W max
USB-A QuickCharge: DC 5V2.4A / 9V2A / 12V1.5A (supports QC 3.0)
USB-A: DC 5V-2.1A Max (no quickcharge)
Attention: all ports can be used at the same time but if so without PD or QC
Dimensions: 132 * 65 * 11mm
weight: 208g
Box contents
The box contains the powerbank, a low-quality Micro-USB-to-USB-A 1in cable (which you can safely throw away) and a short manual.
Sadly, there is no sleeve/pouch/etc.
Design & built
This powerbank targets the compact department as it is both small and leightweight. I owned an Anker PowerCore+ 10000mAh powerbank before and I like this one better: It is a little bit larger but alot thinner. Even it is made out of plastic, it still looks classy with rounded edges, a clean top and a rubber-coated bottom.
It features 4 ports, 4 LEDs to indicate the battery state and a button to turn on the LEDs.
Usage
The powerbank provides 2,5 charges for the Pixel 2 XL with near-than-zero power losses. Power delivery works perfectly and the Pixel 2 XL starts rapid charging when connected.
Time until full was equal to the stock charger. It can also rapidly recharge when connected to the stock charger via USB-C.
The first LED turns green when PD/QC is active which is a handy indicator.
Accessories
Since the powerbank does not include a USB-C-to-USB-C cable, you need a 3rd party cable. The cable that is included with the stock launcher works fine. Nevertheless I purchased an Anker PowerCord II USB-C-to-USB-C cable (3in) which provides Power Delivery, is high quality and fully spec compliant.
I have not purchased a sleeve yet but am planning to do so. Since the powerbank has nearly the dimensions of a common smartphone, it should not be hard to find one.
Verdict
I highly recommend this powerbank. It provides enough power for 2,5 charges, charges rapidly and has a good built quality. For me, it hits the sweet spot between capacity and portability.

Where is it sold? Sounds like they are ripping off the Aukey Amazon name.

I bought it at Amazon Germany:
https://www.amazon.de/10000mAh-Auck...d=1516980877&sr=8-1&keywords=auckly+powerbank

I got one too. It's very nice. Love it. Keeps the charge and my wife uses it all the time. I take it out of her purse and charge it once per week. It's remarkable how much capacity this can hold.
