Zagg Sparq 2.0, extended battery replacement?

Hi guys,
I have bought this interesting gadget and wanted to draw your attention towards it and ask your opinons and views. This post might be helpful to particulary those who doesn't want to compromise the looks of their HD2 with the bulky extended battery "The Camel Hump".
Also I am attaching some pictures of my device. The one that I have is version 1. In version 2.0 one of the 2 USB outputs can give power upto 2000amp while in version 1 the USB outputs are only 1000amp each. So please guys post your views and help others making good choices, or on the other hand save them from pain or waste of money.
Although they advertise on their website only Iphone and Ipad, it does work with HD2 and any other device that can be charged with a USB.

does it work with htc desire? has anyone tried so far.

urh.. i've read about this before.
it took like 9 hours to charge itself and occasionally drain the connected phone battery completely :/ did they fix that? (version 1.0)
how many charges can you get out of that with the hd2 stock battery?

I just bought one of these (with a 50% off coupon ) and it works as advertised. I've only charged the phone once so far, so I can't comment on longevity yet.

T-Mobile HD2.

I bought the official HTC version of this for my TP2 (and now using it for my HD2), and it works great! I just keep it in my bag and whip it out (along with a USB cable) when i'm out and about and the mobile battery is about to give out.
The Sparq 2.0 looks good, especialy as it 6,000mAH, which you should be able to get a few charges of the mobile out of. Does it work? Or do the problems Rhinzo mentioned still exist?

I bought this battery two weeks ago. It does work with the HD2. Based on the capacity of it one would assume it could last up to 4 charges but I find this is not the case, I get about 2 and a half full phone charges out of it. Note that:
- I left the phone plugged in overnight (so longer than a full charge would take)
- I haven' "trained" the battery yet to reach its full capacity
- Efficiency of charging one battery out of another is probably not 100% in any case.
Alternatives which I haven't tried are the powergorilla and minigorilla batteries. They are a whole lot more expensive though.

[Q] Slow performance when using MHL HDMI adapter

Yesterday I got an mhl adapter (a Samsung one).. however whenever the phone begins to display to HDMI, overall performance goes down to the point that any interaction with the phone lags pretty severely.. Has anyone else faced the same issue?

Yes I have.
You gotta remember, just how much more work the Note is having to do in order to render images on two displays at once when you have the MHL adapter hooked up. Both devices still have the exact same GPU in them, so you're asking the same hardware to do completely different work.
Example:
The SGS2's screen resolution is 800*480 on its own, so that's 38400 pixels, or 76800 pixels when the MHL adapter is hooked up (800*480)x2. So, even the SGS2, when rendering 76800 pixels while using the MHL adapter, is still less than what the Note renders on its own with just one screen (1280*800 = 1024000 pixels). So when you hook up the MHL adapter to the Note, and now all of a sudden the GPU is tasked with rendering 2048000 pixels, it's no wonder things start to bog down a bit...
That said, even 1080p video playback should be completely smooth, as video rendering uses a completely different engine.
So to sum up, SGS2 with MHL adapter = 76800 rendered pixels, which is less than the 1024000 rendered pixels on the Note without the MHL adapter attached (which is why it's so smooth on the SGS2). With the MHL adapter attached, the Note is having to render 2048000 pixels, which is really pushing the boundaries of what the Mali-400 is capable of.

Now about that i bought the mhl converter and i just put it on the phone without a hdmi and hooked the charger on it. I noticed the phone want even charging it was losing battery from 45% did go to 25%. Is this normal? The phone just pushes the images to mhl even without a second display to be connected to it?!?!?!?

This is due to how much processing power it takes to drive two displays at once. The phone is having to work exponentially harder, thus if the workload exceeds the power being provided by USB, it will make up the difference by drawing from the battery.
The Note's charger is 1 amp I believe. Try using the 2 amp charger from a galaxy tab instead. That should provide enough power to drive the Note on MHL, and still have enough left over for charging the battery.

I didn't notice any significant slow down when I used my mhl adaptor? I only played angry birds on my 55" plasma though, and I use it to play music. and i have a snidy chinese one not the official one.

Why is there no option to turn off mirroring on the phone. I hate having a movie playing on both screens, it is such a waste. Does ICS fix this??

The problem is that i didn't have a second display on the mhl it was only the charger but still phone was losing battery. It should recognize if another display is on it or not

I understand that the phone definitely has a lot to do, but I'm worried that my phone isn't functioning right.. Especially that it seems that there are other phones out there that don't face this problem.
If you take a look at the video in this post: http://forum.xda-developers.com/showpost.php?p=19068253&postcount=1
And especially the part with the n64 gaming, it's clearly very smooth. Mine doesn't get anywhere near that.. The video, sound and input all lag/chop..
I was hoping to find if anyone else faced and solved this or a similar problem.. :s
Oh, and also of note is that my battery drains even while it's plugged in (but both displays are on), even though Samsung clearly states that the mhl adapter should charge the phone while in use...
It seems to me like it might be a performance issue on the phone side (I'm on stock). Any suggestions? (but preferably I'd rather not have to switch to a custom ROM, at least until a stable cyanogen mod gets released)

I don't understand why there is a 1080p output when it really laggy. Is there a way to make it 720p ?

I would assume the display lag when using an MHL - adapter should lessen a bit when ICS is released. After all, Gingerbread uses software to draw its graphics which is already in and of itself a slow process, not to mention when it has to draw two displays in software. ICS, on the other hand, can draw most things with hardware-acceleration and thus the impact on performance is much lower.
As somewhat anecdotal evidence I may offer you the fact that I have an Iconia Tab A500 which originally runs Honeycomb. Honeycomb doesn't support hardware-acceleration either, so the situation is similar. However, when I slapped an ICS ROM on it I saw a large performance-boost in almost all operations. The thing about A500 is that it also runs a dual-core CPU, has the same amount of RAM as Note, and has even the same screen-resolution.

That is not how it works.
When you plug in the mhl adapter it renders the phone screen resolution and the TV resolution. It doesn't simply double the resolution.
For example the sgs2 renders 2457600 pixels on a 1080p tv.
The note however would render 3097600 pixels in the same case.
There is higher load on the note, but nothing too extreme.

Is this safe to use on a regular basis? Does this mean if I use the Galaxy Tab charger for my Note that its battery will get charged faster? Is there any risk of fire/explosion or damage to the battery or phone if I use a charger with a higher amperage?

Simply put, MHL sucks! I'd like to strangle whoever came up with it. Bring on dedicated HDMI ports, even better HDMI with power capabilities.

Bump...
Does anyone know if this is safe to use? I can pick up a spare Galaxy Tab charger tomorrow, if it means I can replenish the Note's battery faster than it drains during HDMI hookup/output.

Tronsmart Titan Quick Charge 2.0 5 Port Desktop Charging Station

The good people at Tronsmart sent me this desktop charging station to review, so here it is!
All round a rather nice charging station available on Amazon - http://www.amazon.com/dp/B017OLP8UE

Real TITAN among all chargers
Remarkable product really. Here's my summarized review:-
As always, this review is split into following categories:-
- Boxing & Contents
- Build Quality & Design
- Functionality & Performance
- Pros & Cons
- Conclusion
Boxing & Contents
I have been using multiple other Tronsmart products and I couldn't help noticing that they have recently replaced their usual brown boxes with white elegant boxes (still eco-friendly/recyclable) which actually look nicer. On opening, you can expect the following items inside:-
- Tronsmart UC5F Desktop Charging Station
- 2.5 ft Power Cord
- 1 Warranty Information Card
- 1 VoltIQ Information Card
Yes, there are 5 USB output ports, yet there is no USB cable issued along with this unit. This might not be a problem to few since each USB device comes with it's own USB Cable, but there will be several people out there who carry their OEM charges along and they would need additional cables to use with this unit. Its a dissapointment for sure even though you can pick a set of 5 USB cables for just 10 bux on Amazon from any reputed brand.
Build Quality & Design
This is one category where Tronsmart has never dissapointed me. I liked the build quality and design of the first product I ever used from this brand and I like the new ones even better. They have been improving their product quality with every product they release. Living upto its name, Tronsmart Titan is the best desktop charger I have ever owned. With the dimension of 6.2" x 3.3" x 1.1", this is a very solid charging unit with good aesthetics. Surely it's bigger than any of the other desktop chargers out there, but with 5 Quick Charge 2.0 supported outputs, I wouldn't expect anything smaller than this for avoiding the heating issues like any other fast chargers.
It has a bright green LED which could be a good or a bad thing depending on where you use it. The unit the unit also has a classic switch for turning it on/off for convenience.
All in all, it definitely gives impression of a premium product.
Functionality & Performance
With an output of 90W, this thing is a beast. As per the specifications, each of it's 5 USB outputs supports Quick Charge 9V/2A and 12V/1.5A. Morever, all of them are equipped with VoltIQ technology, so, no matter if you're charging a less powered bluetooth earbuds or high powered flagship phone, this unit can detect the best output for each connected device.
Unfortunately, I only have 2 fast charging devices, so I couldn't test 5 simultanous Quick Charge connections but this thing didn't even warm up while I had connected 2 Quick Charge phones, 2 smartwatches and 1 earbuds. Unlike many other multi-port chargers (with QC2.0), this didn't even make the humming sound ( you can hear it very lightly only if you touch your ears to the unit surface). Until now, my favourite was Tronsmart 54W Desktop Charger but this has just replaced that in my bedroom. With this unit, I wouldn't have to worry about which device I'm connecting to which port, I'll just throw it in any of them and let it work on that!
The size of this desktop charger is probably bigger than any of the other desktop chargers but I have been told that this is done to accomodate enough space inside so that the unit doesn't heat up even when 5 QC supported devices are charged simultanously and that works pretty well as far as I could test. Also, if you use it on your desk like me, the size wouldn't be a problem at all.
Now, no matter how much I like this charger, there are certain things that could be incorporated for a much better experience. I've listed them below.
Pros & Cons
Pros
- 90W Output with 5 x Quick Charge 2.0 ports
- Excellent build quality
- VoltIQ in each port
- A Power Switch
- No heating problem
- No humming sound
- Power LED
Cons
- Power cord could have been longer. 2.5ft is too small to reach top of a desk.
- Inclusion of in-box USB Cables
- Power Switch could have turned off Power LED (currently it doesn't)
Conclusion
If you own more than one QC Certified devices and you're looking for a desktop charger, your search ends here.. Just get it, you won't regret it at all!

[Review] EasyAcc 20000mAh QC 2.0 Power bank & Dual Port QC 2.0 Car Charger

Disclaimer: I was sent these items in exchange for my fair & honest review
EasyAcc 20000mAh External QC 2.0 Enabled Battery Pack:
Overview
I have used external battery packs for a while now when I travel, or while at school. EasyAcc made a large 20000mAh tri-port external battery that has some interesting features.
What’s in the Box:
-EasyAcc 20000mAh power bank
-USB A-C cable to charge the battery
-USB A-Micro standard charging cable
-Documentation
Ports/Charging:
EasyAcc included 4 ports on their battery pack, but only 3 of these are used to charge your phone. The first one is a Qualcomm QC 2.0 enabled port. This one will allow you to charge your phone faster via the quick charge standard with a total output of 15.03W max just like Samsung’s Adaptive Fast Charger. The other two output ports are referred to as ‘Smart’ ports. This is just another way of branding the technology (Tronsmart has their Volt IQ, and Anker calls it PowerIQ). What this does is allow the phone to recognize the power bank and use all of the pins as ‘charge only’ instead of data transfer so the maximum speeds via a 5V port can be utilized. This is more commonly known as a charging port with the standard 5V/2.4A output given a fancy name.
The last port on the power bank is a USB Type-C input port. I was a little disappointed to see another manufacturer opt to only use USB Type-C as an input rather than an input/output which would have been a lot more useful for those of us that also have a Type-C device. The use of a Type-C input still allows for the battery to charge at 5V/3A (15W) which would be fast enough to satisfy most people. I personally do not like having an external battery that takes seemingly forever to fully charge. That would hurt how useful the battery would be, thankfully that’s not the case here.
Design/Build Quality:
This battery isn’t going to reinvent the wheel with its simple rectangular shape, but it does have a few things to set it apart from the crowd. First the top/bottom corners are rounded off at a nice angle to give it a nice feel. Second there is a power button conveniently located on the side instead of the usual top/front of the battery. On the opposite side of the battery you will find the Type-C input put which makes it easier to charge the battery without mistaking the port for an output.
Physically, this is a very large like the RavPower I used to have; the battery is reminiscent of a brick given its size (this is common with large power banks). Along the top you will find a series of 4 blue LED’s enclosed behind a small plastic strip. These indicate the current state of the battery to give you an idea of how much power is left inside. Since the battery is plastic, it does have a little ‘creek/give’ when you pick it up sometimes. I won’t say this is atypical, but some of my other battery packs that are also plastic don’t suffer from this. Lastly I will touch on the color, EasyAcc offers two different combinations, black/black, and black/orange; the one I was sent is black/orange. This combination isn’t too appealing to my personal tastes, but it might be to some of you, so I won’t go further into that.
I was able to get 3.15 charge cyles (11355 [mAh]) during my normal usage of the battery pack. I know this is short of the total capacity, however, the battery is at a lower voltage than the one it needs to charge at. This is the case for every external battery I have seen. This creates some efficiency loss, especially when stepping up to 9V for the QC 2.0 port. I think the charging results were acceptable given the number of factors that contribute to efficiency loss during charging. No battery will have 100% efficiency, or anywhere near that, so this is still a good battery.
Charging Results Table:
Charging Multimeter test:
Charging Ports:
Here is breakdown of the voltages/rates the battery can be charged at:
Output Smart Ports: 5V/2.4A (12W)
QC 2.0 Port: 5V/3A (15W), 9V/1.67A (15.03W), 12V/1.25A (15W)
Battery I/O Rating Pictures
The battery can charge up to 3 devices at once with its 3 output charging ports. The first and most relevant of these would be the QC 2.0 port. Since the S7/S7 Edge can utilize the faster charging rates it’s nice to have that option. I tested the battery by charging both my S7 Edge, Nexus 6P simultaneously without any issues.
Overall[SIZE] The battery pack might not be the best looking or most durable one out there, but it gets the job done. I liked the idea of a Type-C input port, although I would prefer a dual use Type-C in/out instead to help future proof the battery. There is a lot of potential in this battery given its 3 ports 1 of which is used for QC 2.0
EasyAcc Dual Port QC 2.0 Car Charger:
Overview Finding the right car charger can be difficult given how the needs of each person will vary. I have car chargers from: Incipio, Tronsmart, Samsung, Belkin etc... the use of a certain one will depend on what I need from it.
Ports/Charging
There are two ports on this particular charger like many others that I have. The first of the two is a Smart port, while the second is a QC 2.0 enabled one. Here is a quick recap of what the Smart port is as I wrote above:
The other port is referred to as ‘Smart’ port. This is just another way of branding the technology (Tronsmart has their Volt IQ, and Anker calls it PowerIQ). What this does is allow the phone to recognize the power bank and use all of the pins as ‘charge only’ instead of data transfer so the maximum speeds via a 5V port can be utilized. This is more commonly known as a charging port with the standard 5V/2.4A output given a fancy name.

What’s in the Box:
-EasyAcc Dual Port Car Charger
-USB A-Micro standard charging cable
-Documentation
Design/Build Quality:
Like many other car chargers this one is primarily, constructed out of plastic. The charger doesn't sit flush in your outlet which can either be a good or bad thing depending on your car/preference. The backside has each port's label, and they are color coded for even easier quick identification; the QC 2.0 port is always orange, while the regular Smart port is white. When looking at the charger you will notice that it has a glossy finish on the plastic which isn't ideal for fingerprints, and will show scratches a lot easier than one with a matte finish. It makes the charger look a little 'cheap', yet at the same time it does not affect the overall durability of the charger.
Charging Ports:
Here is breakdown of the voltages/rates the battery can be charged at:
Output Smart Ports: 5V/2.4A (12W)
QC 2.0 Port: 5V/3A (15W), 9V/1.67A (15.03W), 12V/1.25A (15W)
Ports
Rating
Overall This is a simple car charger that worked well during my testing. Both of the ports output their rated current when testing them. Other than the glossy finish the charger should work well for anyone that wants a simple dual port quick charger.

[Review] Tronsmart Presto 12000mAh USB Type-C/QC 3.0 Power Bank - Best yet!

Seeing as though power banks are a dime a dozen and there are a billion knock off brands out there, I tend to only trust a few brands that have proved their worth. Here is my review of the newest offering from Tronsmart. I am on the trade in your Samsung every year plan, so this will definitely be useful for any of the upcoming Samsung flagships. It the best of past,present, and future.
Look/Feel
First impressions were very good. The Power Bank was packed well, in the typical Tronsmart purple/white packaging and came with a good quality USB-C to USB A cable for charging the bank itself. The bank itself has a good sturdy feel and seems to be made well and out of quality materials. The matte and glossy black make it look very high end. There are white leds to indicate the remaining power level in the bank. The power button has a nice tactile feel.
Performance
The Volt IQ did a good job of recognizing the my phone and applying an appropriate amount of power. It recognized the various devices I plugged in and adjusted the voltage and amps accordingly (Bluetooth speakers, headphones, droid mini, tablets, etc).
The Power bank charged my S7 Edge with typical QC 2.0 voltage and amps (it supports Quick Charge 3.0, but my phone doesn't).
- The highest I saw was 9V @ 1.62 A.
Overall impressions are excellent, I would buy this product again. It is well made, did not get hot, performs great and looks nice. The 12000mah is plenty to charge my phone 3 times from empty to full, or my kiddos tablets 3 times. It is a reasonable size and weight compared to others I have purchased. I have no desire to carry a brick sized power bang with me.This one is ideal for travel, camping, beach trips, or just heavy phone use days. I do wish it came with a USB-C to Micro usb as micro is still the norm and will need a few years to fade out. I'll be ordering one so I can utilize both ports at once.

The S7 Edge has a 3,600 battery
3600*3.5 = 12,600...
Besides power banks never give you the exact capacity it tells just like the usb drives for example.
Seems to me just as if you're just promoting tronsmart.

Great use of the calculator. It was just an estimate. Besides, I rarely kill my phone to empty, so this would definitely give me 3 nightly charges.
I'll humor you and change the op.
I do reviews on tronsmart products because they fail to let me down. Some I have purchased and some were sent to me for review. I also do reviews on all the other cases and gadgets I purchase.
