Is this safe? Solar power charger

I was out of the country recently and could NOT get to a charging source. So i was wondering what if i had one of these in my backpack? Would it be safe for my phone or would it mess it up because of the charging output?

Since our ac charger output is at 5v 1a or 1000ma....
Its weird this charger output is 5.5v. Most I've seen are 5v output.
My friend had one from another brand with 5v output no problems.

If it were me....
I wouldn't use that charger if it is pumping out 5.5v. The batteries in the phones are LiPo batteries which need to be charged in a very specific manner. If they are over charge or under charged it can and will do permanent damage. And if the OE charger is 5V i wouldn't risk it.

Don't go cheap when you consider solar/power pack options. You need to consider the power output of the stock usb charger and try to stay as close to those numbers as possible.
I've had a solar panel setup from Brunton for several years and it's excellent quality and provides the power needed via a car cigarette lighter outlet. 6 watts is the lowest output rating I would go (500mA @ 12V). I bought my first one for $106 when the Dell Axim x50v was a new product and even bought a 2nd one (last one moontrail had for $89.95) for my emergency survival pack. Excellent camping/hiking accessory I wouldn't be caught without, especially with power-hungry GPS devices.
Here's a link to what I use: http://www.moontrail.com/brunton-solaris-6.php
I've tried several rechargeable battery packs and had to return them because the only pack I've found that would charge my phones more than once was purchased several years ago, from PPCTechs.com. It cost me $60 (from what I can remember) and is rated @ 4400mAH and charges it at least 3 imes. They don't carry the product anymore...
When it comes to solar power, you're going to have to pay a little more money for reliable products...

Onite 5V 3A Universal quick wall charger for Note 4

If you have a Nexus 6, Moto X, Galaxy Note 4, or any other Qualcomm Quick Charge 2.0 compliant phone or tablet, you need a high output “Super Charger” like this one to get the full charging speed that those devices are capable of. On my new Nexus 6, this charger took me from 30% to 92% in 30 minutes of charging!
Pros:
+ Fast and powerful.
+ It runs silently.
+ Good quality build, including a nice quality cable and plug.
+ Quick Charge 2.0 compatible.
Cons:
- Bulkier and heavier than most chargers.
- The LED light is much brighter than it needs to be.
- The prongs don’t collapse, so they are at risk of getting bent in your laptop case or bag.
This Onite 3.0A is well made and very powerful. I strongly recommend you get this or another 3A charger like this if you have a Quick Charge 2.0 compatible phone or tablet. I received mine for free, to review, but am very happy with it.

Am I missing something. I'm not using the "quick charger" that came with the Note 4, but shouldn't chargers ALWAYS run silently?

Thats not a quick charge 2.0 charger, the quick charge chargers use 9v's to charge instead of 5v's

Spammer. He doesn't even know the technology enough to be a reviewer.

note 4 charger（quick charger） is 9v,1.67A instead of 5V
note 4 quick charger is 9v, 1.67A. Though 5V 2.0A is also OK, while no quick.
Considering 5V 3A, maybe it is faster than 2A. But the IC will prevent from higher current.

I actually ordered and tested this charger. It seems as fast as my other 2 Amp chargers. All of the reviews of this charger on Amazon are from other people who've been given samples from the seller. Don't waste your money on this charger.

I'd never buy anything from Onite. Spam threads from them, like this one, seem to pop up quite often.

Powerbank that support Quick Charge 2.0

Any good powerbank out there. At least a 10000 mah above.
To be able to use fast charging feature in Note 4.

Actually that sounds like it would be really cool if it exists, I'd also be interested in knowing if there's a powerbank that supports quick charge. I've held off on picking up a powerbank for a while now, but if something like this is even possible it would probably get me interested, it'd be pretty awesome to be able to just plug in to a backup battery and have it charge up the phone with quickcharge speed ;P I wouldn't be surprised to find out it's not possible though... Anyone know?

Think the dual voltage 5 and 9 volt needed for quickcharge wil be a problem to design a powerbank with a feature like that. I don't say it's impossible but probably won't be cheap or small formfacfor

Yea. Is cool if fast charge powerbank then bring out to fast charge note 4. Lol.

There is this compact power bank (and it supports quick charging itself within 3 hours - via 2.1A input - at least on paper)
APE MP5200Q on Alibaba (not aliexpress)
Weight: 132g
Input: 5V/2.2A
Outport: 5V/3.5A,9V/1.5A,12V/1.5A
3 output ports: 2 USB ports and 1 built-in micro USB cable
Over-charge/discharge, over-current,short protection
Quick Charge output port: output 9V/1.5A or 12V/1.5A on Quick Charge state
Battery Cell type: Samsung Li-ion 18650
Quick charge 2.0: Class A
and it looks good too!
the only missing thing to make it a perfect power bank, would be 15W wireless charging capability...

Please everyone do say what Power bank you have
& how much time does it take to fully charge a Drained battery
So we know which charges how many times, Once or twice or more ....
Thank you all

I have aukey quick charge the silver 10400mah model its charge lg g4 same as qc2.0 wall charger I have mah meter

I also have an aukey but the PB-T2 model 12000mAh. Have quick charge USB outlet and also a normal 1A USB outlet. Has a 2A microusb input for charging an a so-so LED light built in. A bit heavy and slightly longer than the Note 4 in size. Cons: I would have preferred a 2.1A instead of the 1A USB outlet for fast charging other non quick charge devices.

As above Aukey Quick Charge 2.0 external battery packs are pretty good. They do them in different sizes and go above 10000mah

BlitzWolf looks good.
banggood.com are doing pre order, to be sent out 20th November.
From a store rep..
We use the newer chip FP6600 that not only supports QC but also standard fast charging, the Aukey does charge at QC speeds with their THY100 but will not fast charge other devices such as your iPhone at fast speeds. BlitzWolf's newer IC provides compatibility beyond just QC devices. The battery of the BlitzWolf is is LG and also of a higher standard than Aukeys domestic Chinese brand batteries. In terms of safety and compatibility this is one step ahead of Aukeys 6 month old version.

I am using Aukey Power Bank with 15000maH.
Supports Quick Charge and PowerBank itself charges as Quick Charging.

Hmm... we have Note 4's a removable battery is more compact and supports quick charge. Just have to get a battery charger that supports it. There would also be less power loss because it would be more efficient than transferring energy from one battery to another. Just my opinion.

Question How to make wireless charging faster?

So, when it is about charging, this Galaxy S21+ (Exynos) can be really choosy. With a lot of chargers, it difficulty reach 1.3A. Only few of the selected chargers (my Lenovo 65Watt laptop charger, IKEA 27Watt charger) it could reach 2A charging with wired. For wireless charging, it's even worse. Currently I owned 3 wireless chargers.
1. Energizer 15Watt charger. Never even shows Fast Wireless Charging.
2. Samsung EB-U1200 Wireless Charging Power Bank. This one shows Fast Wireless charging. It could charge up to 2A for a while and then once the battery temp hits about 39C (and it hits there within 5 mins), it throttles.
3. Huawei SuperCharge 27Watt Wireless Charger (with Huawei 22.5Watt SuperCharge Charger and 5A cable), performs same as Samsung Power Bank. Reaches up to 2A, then battery heats up and throttles.
I've tried different ways, including removing the phone case while charging but result is still the same. Does any of you have similar experience? or is it just my phone? Please advise me how to make wireless charging more efficient.

I've not tried wireless charging however for wired you need a charger that supports USB C PD PPS (this is a fairly new standard) and without this you won't get anything more than about 2A.
This Ravpower charger for £16 (£13 with current voucher code) works a treat hitting 4.6A when the battery is empty reducing as the battery becomes full. You have to use USB C to USB C to achieve this.

My guess is there will be a similar standard for wireless charging that you need to adhere to.

Question Max charge rate for Moto G Stylus (2021)?

So when you buy a Moto G Stylus (2021), it comes with a 10W charger. And 10W that is sort of what is cagily listed on the Moto website for this device. But when I plug it into a QC3 charger, I get about a 14W charging rate (5V x 2.8A). Does anybody know the maximum charge rate for this device, and specific charger models that can provide it? Would a USB-C PD charger at a higher wattage be able to charge at a faster rate? Thanks in advance for your comments on this matter.

To answer your question, yes a USB C PD adapter would provide faster charging. So long as it's QC 3.0 or higher. 18W or 30W should be fine, I believe the phone input charge maxes out at 15 Watts (absolutely no permission to quote me on that lol) so if you don't mind a bit of heat and the potential of degrading your battery slightly faster than with charging on a standard 1A, 2.4V charger, then the 18W or 27W USB C wall adapter that is compatible with QC 3.0 or 4.0, should be sufficient. Don't forget to grab a couple good grade USB C to C cables as they are often the first thing to go bad and prevents turbocharge from kicking in.

Thanks for the comments, @mario0318 So if I am currently seeing 14W (5V x 2.8A) with a QC3 charger, it sounds like I may be near the max already if it is only 15W. I have no USB-C PD chargers yet that I can use to test, but there was a 25W Belkin model on sale today (for Black Friday) for just $10 so I ordered myself one. When it comes in, I'll test it versus the QC3 charger to see if there is any significant difference.

So I have a basic update here. The QC3 charger I mentioned has an LED readout on it, and that is where I got the estimated 14W charge rate (as 5V x 2.8A). The new 25W Belkin charger I got does not have an LED readout for V & A on it, however. So I turned to the Ampere app on the Play Store. Then I swapped back and forth between the two charging systems and watched the estimated charge rate on Ampere. The 25W Belkin charger definitely shows higher charge rates according to the Ampere app. But I've ordered myself a USB C charge meter (like the old USB "doctor" meters, but with USB C connections) from China to document it more closely.
I might be missing something, but one thing I see lacking with the Ampere app is logging capability--it seems like its strength is just showing rates in real time. It would be cool to find an app that can not only monitor in real0time, but also log charging events with V & A stats, etc. I see AccuBattery may potentially provide this. Or any suggestions out there for another battery charge monitoring app that you think might do the trick?
For those potentially interested in the 25W Belkin charger, the specific model is the "WCA004dqWH", and it is on sale now for $10. It is actually mentioned in a news snippet here at XDA:
https://www.xda-developers.com/belkin-usb-c-25w-charger-deal-november-2021/

I think the Battery Manager app by 3C allows recording logs for power charging events. But I forget if there's a limit with the free app compared to the paid/donate unlocked features.
Regarding the charger wattage, I'm fairly sure anything past 25W would be over kill for charging a single device like the 2021 moto g. At that point it becomes more suitable for two devices, with anything far higher like 60W or 85W being totally unnecessary and potentially harmful.

Thanks again, @mario0318 , for your new comments. I agree that anything beyond 25W would be overkill for this phone.
As a further update, I decided to swap over to AccuBattery, and upgrade to the Pro version. As my Stylus was already charged, I decided to try the two chargers with a Nord N10 5G that had arround a 40% charge. The QC3 charger was charging at an average of 1993 mA with the screen off after I left it sit for a few minutes. When I swapped to the 25W Belkin sytem, it jumped to 2993 mA under the same scenario so like a full 1 Amp difference. These are about the same differences I noticed between the two chargers when charging my G Stylus (2021), but I did not want to say that above because they were off-the-cuff observations. But I took screenshots with AccuBattery this time so no apprehension in stating values this time around. I'll do the same with my G Stylus next time it needs a charge.
AccuBattery suggests only charging up to 80% capacity vs. 100% capacity given the wear and tear difference on the battery. I guess I'll try that, but in the long run, replacing the battery on the G Stylus (2021)--if it ever becomes necessary--looks pretty doable based on teardown videos.
