USB charger is putting out 5.24 volts any Danger??

So I just bought a anker usb car charger. To replace a $2 deal extreme cheap charger that I did not trust for charging expensive devices.
http://www.ianker.com/product/71AN2452C-WA
I just took a reading off the anker charger, and it is putting out 5.24 volts with and with out a load.
All my other chargers wallwarts and car chargers put out 4.8 - 5.08v.
Any idea if 5.2v+ is a little too much for a device that only wants 5.0v??

No it's fine, just don't forget to unplug your device after charging is completed.

This is not too much. Most of modern 5V devices are supposed to support charging over USB.
For example, according to USB wiki page: "The specification provides for no more than 5.25 V and no less than 4.75 V (5 V ± 5%)"
So your charger even meets USB requirements .
In fact usually the charging process is controlled internally by the device, so this internal controller will limit the charging current and stop charging if needed.

don't worry, during charging the tension will drop to 5v

[Review] Tronsmart Titan 5 Port 90W Desktop charger & Dual Port 36W Charger

Tronsmart multi-port charger(s) review
Disclaimer: I was sent these items in exchange for an unbiased review.
Tronsmart 10A/90W 5 Port Quick Charging Hub
Tronsmart 5 Port Titan
Overview
There was a point in time earlier this year where I had 5 phones, and a tablet which all needed charging. When I would go to school, or travel it was always a hassle to bring multiple chargers, and cables whenever I decided to charge more than 1 device at a time. My wife would also need to charge her phone which only added to the number of devices that needed to be charger. I no longer have an excessive number of phones, or a tablet, but this Tronsmart 5 port 90W charger would have made things much easier.
The charger itself is rather large, but it is meant to sit on a desk/nightstand so you can plug in all of your devices and charge them quick if they support QC 2.0 or even 5V/2.4A (as iphones, and older android devices do). Each port can supply the same amount of power even when you have 5 QC 2.0 devices side-by-side on charging; needless to say this charger can really deliver the power needed without carrying around multiple separate chargers. Tronsmart claims this charger has the highest overall output of any 5 port model, and I agree with them.
Update [1/7] Tronsmart stated they are going to include a longer power cable in the future (sometime soon). I will also be adding more to the OP in the next 1-2 days
Update [3/15] I was sent a longer power cable that works great. It is now 5[ft] long which is a big improvement over their previous 3[ft] cable. I can now position the Titan better on my desk without having to rearrange things like I did in the past.
What’s in the box
The charger includes a power cable and some informational cards inside, but the setup is self-explanatory.
Build & Design
The charger is small enough to carry around if you wanted to in a small bag, but it’s still fairly large. On the bottom side there are 4 rubber feet which keep the charger from moving around while stationary on a desk. The overall construction is a nice feeling plastic with glossy edges, and a matte center that create a nice contrast and ‘premium look’. The charger feels right at home on my desk next to my Surface Pro 4 Dock even though its bigger.
All 5 of the ports are green on the inside just like Tronsmart’s other charger I was sent. This gives the charger a nice look, and can help you locate the ports when it’s a little darker inside. The power cable for the charging station measures around 3[ft] which is on the shorter side. I would have preferred if the power cable were at least 6[ft] for convenience.

Charging
I only have 2 Nexus 6P’s right now to test the charger with, but I will try to get some of my friends together and charge phones on all 5 ports simultaneously. I used a USB voltage multi-meter to test the output of the ports along with a Tronsmart Type A-C cable to charge my Nexus 6P. When powered on there is an indicator light on the front right hand corner that will turn green as a nice touch. The port consistently giving 5.3V/1.55A via the A-C (correct 56K resistor) cable. This is what I would expect given the way A-C cables are supposed to behave. The charger will ramp up the voltage for QC 2.0 enabled devices to 9V and 12V depending on the way Qualcomm defines their charging.
Outputs:
5V/2A (10W) , 9V/2A (18W), 12V/1.5A (18W)
Test with my Nexus 6P and a Tronsmart Type A-C Cable
Summary
I am impressed with the quality and performance of this charger, and I would buy one as a gift for someone who needs some serious charging capacity for their home/office.
I would like to see a longer power cable supplied in the future, but other than that small detail the charger is excellent!
[3/15] The new longer cable is great, and now I have more flexibility with its positioning.
Tronsmart 4.8A/36W Dual Port Travel Charger (QC 2.0)
Tronsmart Dual Port Travel Charger
Overview
This charger is a great portable way to charge multiple devices in a smaller package. The charger can output a maximum of 4.8A (2.4A each port) and 36W giving you the ability to quick charge your devices.
What’s in the box
The charger includes 2 USB Type-C to Micro USB cables along with some documentation.
Build & Design
This charger looks like a miniature version of the desktop unit above. It features the same plastic construction with a glossy edge/matte center. A nice little feature of this charger is the ability to fold the plug nearly flat (the very tips of the plug stick out so you can easily unfold it) which bodes well for its portability.

Plug extended
Charging
Tronsmart’s charger will output the same 18W as their desktop unit allowing you to somewhat future proof your charging needs for at least the time being. The charger also features a small green indicator light on it that isn’t bright enough to bother me at night (a good sign). It’s good to see a multi-port quick charger because last year when I bought my Nexus 6 any QC 2.0 charger, let alone a dual port model was hard to come by.
Outputs:
5V/2A (10W), 9V/2A (18W), 12V/1.5A (18W)
Summary
Tronsmart designed a great portable quick charger that is another nice addition for anyone that needs to charge multiple devices. The charger will still work great even if you have a single device, but the extra port won’t hurt if you get another device.
I will update this review periodically if anything changes, and hopefully I will be able to test all of the ports with QC 2.0 devices simultaneously.

Nice.

[Review] Choetech 50w QC3 6 port charger

Hi All,
I know there is a review for the 55w usb c charger, but here is mine of the 50w 6 port QC 3 Charger (Model Q3-4U2Q). Just to note this was sent to me to review, however this is all my own opinions.
The item is very nicely built, it has a soft rubber texture and feels very well built.
In the box you get the charger itself, a UK 3 pin power lead as well as a USB C cable and a little stand with a rubber base to keep it in place.
The charger itself has 2 QC3 ports (in blue) and 3 normal ports.
Using my usb voltage/battery meter, the QC 3 Ports draw 8.9v and 1.5a using the supplied usb c cable. On the HTC 10 the phone recognises this and shows as “charging rapidly” (very big plus point as not all QC3 chargers do this). For speeds it has charger 100maH of power over 3 minutes, works out about 5% battery on the phone itself. Total charge time is just over an hour.
The normal ports draw 5v over 1.4a, this takes the charging down to about 50mah over 3 mins, which the phone shows as about 2/3% battery. This takes the overall charging time to just over 2 hours.
I then kept the htc 10 plugged into the qc3 port and plugged in other phones into the normal ports to see how many you can charge at the same time.
1) First phone (htc m7) = no difference to charging rate of the htc 10.
2) Second phone (htc 8x) = v remained at 8.9v but amps just dropped down a tiny fraction to 1.46a (did jump around more)
3) Third phone – (htc desire hd) = voltage moving between 8.89v and 8.9v, amp jumping between 1.4a and 1.5a.
4) Fourth phone – (Samsung non smart phone) = voltage down to 8.89v solid and amps still jumping.
5) Last phone (asus tablet) = voltage down to 8.89v solid and amps still jumping from around 1.2a to 1.4a
So I now have 5 phones and 1 tablet plugged in charging into the port. The HTC 10 is still “charging rapidly” only drawing 0.1v less than on its own. In terms of charging speed it has dropped from 100ma every 3 mins to around 50mah every 3 mins (i.e. halved). Unplugging phones the jump point did tend to be around 3/4phones until it actually made a noticeable difference to charging speeds.
During this whole process the charging did not get noticeable hot, it warmed up a little a top but nothing major enough to cause any issues.
For ref - The test took around 30 minutes, the usb voltage meter reads 750maH drawn (including unplugged and putting in non qc3 ports and having all 6 phones plugged in) and the phone has gone from 39% to 82% = 43% jump hike.
Note – The charger does have a small blue led on the front when plugged in, it’s not very bright to light up a dark room but might distract some people if they want to place it close while in bed.
Overall I would give this a good 5/5 stars. Great build quality, the actually does take full advantage of the QC 3 capabilities. It also can charge multiple devices without making too much of an impact on charge speed’s (unless you use all 6 ports). My only downside is the LED light which is just personal preference, can easily be covered up with a tiny bit of black tape.

dodocool Wireless Charger, Fast Charge Qi wireless Charging pad (30% off Code Below)

dodocool Wireless Charger, Fast Charge Qi wireless Charging pad for Samsung Galaxy S7 / S7 Edge / Note5 / S6 Edge+ and All Qi-enabled Devices Black
I have a few Qi wireless chargers and a Qi enabled device (Nexus 6) but never use them mainly because they charge at a very slow rate but this dodocool Wireless Charger has Fast charging mode (Output 10W Max) which uses Quickcharge 2.0 so if your device has Quickcharge capabilities you will be able to take advantage of but if not the Standard charge mode (Output 5W Max) for standard Qi-enabled devices will also work. I can say I now use this wireless charger as my primary charger and even use it in the car and I know that sounds odd and did to me also at first after reading it in product description but the charger itself first off is angled downward which helps you to view your screen and most importantly the charger base has 2 silicon rings around it, one on the top and one on the bottom which help secure the charging base while sitting in care and the silicon ring on top of charger not only helps secure phone while on the charger but also protects phone from getting any scratches or wear marks. I must say I’m very impressed with the overall function and looks of this wireless charger and highly recommend it.

RAVPower 20,100 mAh Power Bank with Quick-Charge 3.0 & USB Type-C Inputs Review

Hey guys,
I was recently looking for a high capacity power bank that supported Quick-Charge 3.0 and USB Type C since I have a Samsung Galaxy S7 Edge and Galaxy Tab S3.
After an extensive search, I decided upon the RAVPower 20,100 mAh 3-Port USB External Portable Power Bank (Model #: RP-PB043) as it seemed to fit all my needs. I honestly couldn't be happier with this purchase and thought I'd give it a review.
Pros:
Huge 20,100 mAh Capacity - Uses six Panasonic 3,350 mAh 18650 Lithium Ion Batteries inside. I opened mine up and I managed to get Panasonic cells. The website says you can get Panasonic or LG, depending on regional availability. I was able to charge my Galaxy S7 Edge a little over 5 times. It has a 3,600 mAh internal battery, so this is a respectable efficiency of nearly 90%. You will always lose some of the max capacity due to heat transfer in the charging process. To figure out how many times you would be able to charge your device... take the max capacity of the Power Bank (20100 mAh) and multiply that by the efficiency (roughly 85 to 90% for this model), and divide that by your devices internal battery (i.e. 3600 mAh for GS7 Edge).
High-Speed 2A Input - Most Power Banks only have a 1A input to charge. This means it would take nearly a day to recharge to full capacity for a Power Bank of this size. Fortunately this model has 5V/2A input. I used the included Quick-Charge 3.0 Wall Charger and the Power Bank was fully charged from 0 to 100% in 4 hours and 50 minutes, can't beat that!
3-USB Port Outputs - 1 Quick-Charge 3.0 Port, 1 USB Type C Port, and 1 is art 2.0 Port (See tech specs below). This means this Power Bank supports pretty much any device you throw at it. The iSmart port will even work with those dreaded Apple products that your family members have the misfortune of using.
LED Light Power Indicator - There are 4 White LED Lights that you can check the % of battery life remaining on the Power Bank.
Full Accessory Package: Includes 1 RAVPower Quick Charge 3.0 USB Wall Charger, 2 Small Flat microUSB Cables, a micro USB to USB Type C Adapter, and a nice mesh traveling case. The short microUSB cables are a godsend because they allow you to keep your devices close to the Power Bank without having a huge wired mess. The Type C Adapter will also come in handy because I always need those in a pinch with my Galaxy Tab S3 since I have so many microUSB cables.
Lifetime Warranty - Yes, you read that right. This Power Bank is backed by a Full Lifetime Warranty with online registration (see warranty card in box). This is something unheard of in the Power Bank industry and really means they stand behind their product and its well-built. Not even companies like Anker offer longer than 18 months.
Cons:
Rather Basic Finish - The Power Bank is matte black plastic and nothing exciting in terms of looks. There are no other color options, so if you have a white device, you're out of luck if you want them to match.
Accuracy of LED Indicator - With only 4 LED Indicators, you are left guessing what % of capacity is left. Each dot represents 25% capacity. 0 to 24%, 25 to 49%, 50% to 74% and 75% to 100%. I prefer having a digital display showing the approximate % remaining from 0 to 100%.
No Built-In LED Flashlight - Many Power Banks have a built-in LED Flashlight for the dark. This model DOES NOT which isn't a huge negative, but I still have found myself using it sometimes on other models when the power went out.
RAVPower RP-PB043 Technical Specifications:
Input (Micro): 5V - 12V 2A Max (QC), 5V / 2A (Non-QC)
Input (Type-C): 5V / 3A Max
USB Output: 5V / 2.4A Max
Type-C Output: 5V / 3A Max
QC 3.0 Output: 5V / 2.4A, 6.5V~9V / 1.5A, 9V~12V / 1.2A Max
SIDE NOTE: Not realizing that this Power Bank came with cables included, I also managed to pick up this unique RAVPower 3.3 Ft. 2-in-1 USB 3.0 Type A & Type C Connector Cable (Model: RP-TPC006). I haven't seen anything like this before and when it was on a special Prime Day lightning sale I decided to snag one. It definitely comes in handy because it can be connected with tons of devices since it has dual-purpose connectors. Not only that, but it is also braided and very high quality. If you're in the market for a Type C cable... it might also be worth considering, especially since it also has a Lifetime Warranty.
