So my DHD arrives tomorrow.
After reading about battery life, I want access to as many chargers as possible.
Can you tell me: Will my existing Micro-USB Chargers (Blackberry) be compatible with the DHD? I'm not sure if each unit will require a specific voltage / wattage?
Or can I just plug & play with which ever Micro-USB charger I come across?
Thank you & sorry if it's a dumb question...
Any cable will do fine. Definitely if you're charging through a PC since I've never heard of a phone/battery that can't handle the 5V it outputs (max for USB charging). A mains charger you can never be too sure with since it may have higher current/watt output, but I've really never let this stop me except that I'd avoid using cheap Chinese knockoffs.
It depends... microUSB connected to computer will be of course good, as it is hardware limited to 0,5A. External chargers are good question, but in my experience the phone/battery usually have a charge limiter so even if the charger does allow you to use higher current, the phone doesn't have to use all the power it can get.
For example i used the Nokia AC-10E charger for my Motorola Milestone since i bough the phone, and had no problems with it. And will use it for DHD too.
The official HTC chargers have an outpur of 5V/1A, so as long as your charger has the same output you should be good.
Nokia AC-10E has 1.2A, but as i said - that is the maximum it can give to the phone, batteries/phones have a current regulators so even if you connect a charger which can give you 2A @ 5V, nothing will happen - the phone will regulate the current which is used to charge the battery.
I lost my wall charger that came with my HP touchpad. The round plug thingie is what I'm looking for. Searching on Amazon brings up a number of items, for example:
http://www.amazon.com/HP-North-American-Charger-TouchPad/dp/B0055QYJJM/ref=dp_cp_ob_e_title_3
However, is there an alternative that works? I was able to use the Evo cable rather than the original HP sync/charge cable that came with the wall charger, but is there an alternative wall plug that works as well? Paying almost $28 for a charging cable seems a bit ridiculous.
Any help and advice would be most appreciated.
[[FOUND MY ANSWER]]
I found that Walmart was having a sale on the North American charger with the barrel wall connector for $11.99 and Meritline was having a sale for 6' long USB to micro-usb cables (pair for $4.99 no tax/shipping).
The listing on the Meritline page says that the cables are compatible with the Evo.
Given that the cable that comes with the HP barrel charger is pretty much monkey spit and fails within a month, I found a solution that works for less than $20.

Pretty much any USB charger will work, but most give a notification on the Touchpad screen indicating that they may not be charging. This is because the official charger is at the high end of both voltage and current capability. I charge from laptop, desktop and a variety of Blackberry chargers with no issue, but the available current will determine how long it takes to charge and whether it charges much while the screen is on. Go for a USB charger that gives you 2 Amps and you should be fine.

Thank you for the advice. To be more specific, can you recommend any alternative charging cables/wall charger units specifically?
Any brand name USB charger that gives off 2 amps should be fine. I tend to stay away from really cheap generic chargers. Any microUSB cable should be fine even a generic one if it has decent reviews. I worry about generic chargers since a poorly regulated one could send a voltage too high, but generic cables should be fine.
The chargers I am currently using, as well as the one that came with the TP, are the one that came with a Blackberry Playbook and the one from my HTC Desire HD.
The Blackberry charger gives an error on the screen that it may not charge the TP, but as it gives 2 amps, charges in pretty much the same time as the official unit.
The HTC again gives the warning and takes about twice as long to charge.
what about the nook color charger i know it higher amps might work as well

I just tested the TP with a charger for the NC, and unfortunately, it still gives the same "may not charge" warning...
There is NO after market charger that will charge at full rate like the HP barrel charger!
At best they will trickle charge at a much lower rate and take considerably longer to charge.
The TP relies on precise signaling which it will only get from the OEM item or specially modded after market units or cables.
Do a google for further info ie webosnation.com forums.
I think your looking for a 5.1v charger, aka rapid charger. This is used by the iPad, and some android phones like the Motorola droid 3, razr and htc rezound.
I could be wrong though,I haven't gotten my touchpad yet.but I do own all said device above (except the razr) and they all use the faster charging technology.

Don't believe all the hype about using ONLY the HP charger, there are many that do the job perfectly well. Too many people make these authoritarian statements and all they do is cause FUD.
At my office, I use the AC charger from my last Samsung phone (mythic) and it works IDENTICALLY to the OEM one. I have also used a Moto and and LG with NO PROBLEMS. I have no issues getting to fully charged in little time.
At home, my OEM cable is plugged into a high-power USB port (2.1A, I believe) and it has no problem charging from near zero to full as well. Front or top-mounted USB ports tend to be 500mA or less, but the rear ones (coming directly off the motherboard) tend to have a higher supply. I also use a non-HP USB cable occasionally and it works fine.
(I got my TP during the original fire-sale and have been charging it these ways ever since with ZERO ISSUES.)

The small voltage difference is marginal and isn't going to matter, the internal hardware should be able to tolerate a few tenths of a volt difference. In fact, I tested my Motorola charger rated at 5.1v and the Touchpad charger rated at 5.2v on a multimeter. The Motorola charger was outputting 5.20v and the Touchpad charger 5.16v. Granted this is at no load, but switching transformers are regulated so they should supply rated voltage at any current draw equal to or less than rated. Also depending on how well the voltage is regulated there may still be a slight AC ripple that the device has to deal with.
Does anyone know the time difference between using the TP charger and a standard droid/blackberry charger? Also curious if the charges last the same. I know theoretically they should since the battery is full either way, but electricals can be tricksiy..

Its all down to the charge rate that the TP is able to draw.
2A which is theoretically possible from TP AC barrel charger would charge the 6A+ battery of the TP from flat to full in approximately 6.5 hours.
If the BB charger were able to have 500mA drawn by the TP then it would fully charge in approximately 26 hours.
The charges would be no different.
To convert any regular USB charger into a TouchPad charger you need to add 2 resistors as per the diagram attached.
The presence of the resistors will trigger the TouchPad to draw the full 2A from the charger rather than the trickle charge it does when they are not there.
Please do not modify a cheap charger that is only rated for 500mA as you will most likely overheat it and it could present a fire risk.

Just pointing out that you need to start with a charger that is rated at least 2Ah to start with.
You can't turn a low rated one into a high rated one.

oh, for the love of gods. REALLY? I was just asking for a replacement cable. I don't want to reinvent the charging paradigm. I just need a simple recommendation for a cable. If a thread could be highjacked any further I don't know how it could be.
I appreciate all your "advice" but seriously, this is NOT what I was asking.
Anyone know if I can get a similar cable in the UK? Kind of lost my TP cable, and I miss the flexibility the long cable gave me, it was so much easier to use on charge!
well i know that my tbolt cable works. i have to use the tp adapter though. my tbolt adapter makes the touchpad say that the charger is incompatible.
I have an HTC Explorer, which came with a USB cable and an adapter to allow me to charge via mains as well. (Something like this: http://i.expansys.com/i/g/g232723.jpg - that's not the exact same one, but you get the idea). This charger says on it that it has an output of 5V and 1A. I also have a Blackberry Playbook, which came with a charger with a micro USB connector. However, this charger says on it that it has an output of 5V and 2A.
I have tested the HTC charger with my playbook, and it worked, but the question I want to ask is this: would it be dangerous to try the playbook charger on my HTC phone? (2A output from Playbook charger versus the presumably expected 1A input on the phone) I would like to be able to only carry one charger when travelling and the playbook charger has interchangeable adapters for international plugs, so it would be better to take, but obviously I don't want to overload the phone and have it burst into flames or whatever.
Any advice on the matter would be great, thanks.
It's not recommended by the manufacturer. It can void your warranty, though I don't know how they'd ever find out you were doing so. There can also be issues when using the cable to transfer data and such.
I did watch a video about that Blackberry charger.
Supposedly because of that 2A output, it charges your phone twice as a fast.

I don't think there would be considerable damages but..I'd just use them both, even if it's less comfortable
I looked around and I think it should be safe. From what I've read online, the phone will only take a certain amount of current, regardless of the current being made available by the charger. Because the voltage is the same (5V), and the resistance of the phone circuitry is constant, by Ohm's law, I = V/R, so I will always be the same as long as V is the same. Presumably it'll drop with a lower input current, but the max I will always be the same, and that'll be limited to a safe level.
It might take a slightly higher current (say if the max the phone can take is 1.2A or something, the 1A charger can only give 1A but the 2A would give the full 1.2A), but no higher than the circuits in the phone will allow. After reading this, I realised that it made a lot of sense, and I think it's right. I also read that if it does charge the phone faster (which it will if the phone is taking a higher current e.g. 1.2A) it'll reduce the number of charging cycles that you get out of the battery. But the consensus seems to be that doing it every now and again when travelling etc. should be fine.
Thanks for all your responses.
EDIT: I think at worst, I might damage the battery, and they're not overly expensive to replace I don't think.
I agree, the rating on the charger is what it's MAX output, not that it will push that much current to your device. If you have an extra USB cable (that you dont mind cutting apart) and a mulit-meter, you can check to see how much current your phone is pulling from the BB Playbook charger. connect your mult-meter in-line with the red wire in the usb cable (just connect all others together)
Just make sure your mult-meter is rated for at least 2A.
Hope this helps.
Devices with lithium batteries usually have a charger circuit that limit the peak current that is sent to the battery. They also utilize temperature compensation so if you are charging the battery too fast, it starts limiting the charge current.
Where you might have a problem is when it's plugged in and you are using it, especially if the battery is low. You get high charge currents, combined with the operating current.
So, I've been wondering this for a while and thought I just ask. I've read about stories where people bought 3rd party chargers and had their phone malfunction. Because of this I have been worried about using any other type of charger and stick with the stock. Would it be fine to charge my Nexus 5 which a more powerful charger. For example the Nexus 7 charger? There's also a few other 3rd party chargers which seem to be much more powerful, but I was just worried that it would cause problems for the phone. Thanks in advance!
I've got a ton of Chargers laying around and they all work just fine. As long as the charger output is 5 volts you should be okay.

the charger that you linked to is 18 W (aka Watts), but it is still 5V. it has a max output of 3.6A (amp). Watts = Volts x Amps.
As long as it's 5V, you should be fine. using a charger with a higher max A rating won't change anything, how much current that is actually drawn (amps) depends on the device.

Oh I see. Thanks!
Okay, quick electrical lesson.
Volts: This one is relatively fixed at 5 for all "USB-Powered" devices. However, virtually all electrical devices have a 10% allowable variance. So... anything from 4.5V to 5.5V should work just fine, and be considered "safe." Of course, this can be tricky since some less-than-trustworthy manufacturers (*cough*China*cough*) will include the 10% variance in the specs. So... a charger rated for 5.5V charger may actually be running at 5.8V, which is within the 10% variance for a 5.5V device, and since 5.5V is within the variance for the 5V spec, they'll just double-down, and stamp it with 5V, which is bad. Confused? Yeah, me too. Just stay away from those cheap eBay chargers, to avoid such shenanigans.
Amps (aka Current): The thing to remember here is that the draw is king. What I mean here is that the device drawing power is what's important. If your device draws 1A, then it will ALWAYS draw 1A, no matter if it's plugged into a 1A, 5A, or 1000A charger. However, it will also attempt to draw 1A if it's plugged into a 0.2A charger, which would obviously be very bad (well, unless you're TRYING to start a fire). USB devices are designed to draw 0.5A, since that's what USB 2.0 (on a computer) provides. However, many devices can draw more if plugged into a wall charger. So... you're almost always safe plugging into a computer, but your wall charger needs to be rated AT LEAST what the device expects. That can be hard to determine, so the rule of thumb is that whatever Amperage charger the device came with is the MINIMUM amperage charger you should use. However, there is no maximum, since draw is king, so go nuts in the other direction.
Watts (aka Power): Power = Voltage x Current, so Watts is nothing more than Voltage times Amperage. Thus, a 5V charger charging at 2A is 10W (5x2=10). Now that you know this, you can ignore it. Nobody but the electric company cares how many Watts your wall charger is pushing. The only, and I mean only, thing this is good for is determining the Amperage if the manufacturer doesn't provide it. So... if the only spec listed for your micro-USB charger is 12W, then you can figure out the amperage by dividing that by 5 (since all USB devices are 5V). Your 12W charger, therefore, is pushing 2.2A. See the section on Amps, since that's what's really important.

The stock charger is 1.2A, correct? So given that much... a charger I have used a few times on my Nexus 4 and 5 at a friend's place only outputs .5A... so at least .7A from what our phones should be able to draw.

An Android device knows that it's plugged into a wall charger, and thus can use more than 0.5A, only if the data pins are shorted together. Otherwise, it will assume it's plugged into a computer and only use 0.5A. Chargers made for android devices are usually so equipped. Apple chargers and some cheap-o chargers aren't. That's one reason why you'll see chargers with nothing more than a USB slot (no cable) specify that they're only compatible with Apple devices. Technically, they're compatible with any USB device, but not at the high charge rate.
Having said that, manufacturers can build in some safeguards. Quality chargers simply won't output more current than they're designed for. How they go about this varies. They may limit the output to their rated specs, they may blow an external breaker, or they may blow an internal fuse (usually killing the charger forever). Cheap chargers may not have such safeguards. Plus, many (if not most) phones/tablets will recognize when they're hooked up to a low-current source, and automatically switch to the low charge rate mode (0.5A).
In short, quality equipment is usually designed to be safe, with safeguards to protect against common scenarios. It's the cheap chargers that you have to worry about, because they tend to cut corners to keep the cost down. Safety provisions aren't technically necessary, and are usually the first to go.
My moto g (1st gen) is about to arrive but I don't know how to charge it yet. I heard it takes long to charge in PC and I need a wall adapter for charging on the go anyways. Original brand ones are really expensive and I want to avoid that cost if possible. So is it safe to use a generic (most likely without any brand) wall adapter? For example one that says 100-240VAC, 50-60 Hz Output 5.0VDC 1.2mah. If not, what should I take into account when looking for a charger?
Thanks in advance.
It's not necessary to use original moto charger but it's recommended you can use any other chargers for charging With appropriate Voltage values...

All USB chargers have a regulated output voltage of 5 volts DC, and all of them are compatible with any device that charges via a USB/mini/micro port.
The difference is the maximum charging current, which generally ranges from a low of 300 milliamps to a high of 2 amps. More current will fill up the battery faster, as long as the charging control circuit on the device will accept more power. Regular USB ports like the ones on your computer are specified to put out a maximum of 500 milliamps current, so most device charging circuits will detect when they are on a computer USB port and limit their current drain to 500 milliamps to avoid triggering a "port overload" shutdown on the computer.
Devices with big batteries (like tablets) will take a long time to charge with a low-capacity charger, so you generally want to use a higher-capacity 2 amp charger with those to cut the charging time. Phones are generally somewhere in the middle - they'll charge in a reasonable time with a 1 amp charger, but they might benefit from using a 2 amp charger. You can still charge them using a low-capacity charger or a computer USB port, but you may need to shut the device off while charging if it consumes more battery power in normal operation than the charger can pump into it. And it might take a very long time (like 24 hours) to charge a big battery from a small charger.

Yes I'm aware of all this. The thing is I purchased it from Amazon and it doesn't come with a charger. That's why I need to purchase one. I know it works without problems with samsung, htc, blackberry, etc chargers but I don't know if it works -without problems and risks- with a generic charger. By generic I mean those chinese cheap ones that "imitate" original ones. So are those safe? Thanks again.
There's generally no problem with an inexpensive generic charger, but cheap junk is cheap junk. If it costs $1.99, and the connections are poorly soldered, the components are under-specified, and the construction quality is generally shoddy, then sure it can easily break, overheat, or go up in smoke. It could even conceivably damage your connected device. Just use some common sense in evaluating when something is too cheap.
I just got a samsung charger which seems to be for the note 2.. My worry is that I'm not entirely sure if it's original (even though build quality seems good) or not because of many reasons: a) I just noticed the model on the box (eta0u10ebecstd) is different than what is printed on the charger (eta-u90ewe) , including amperage listed (0.7a on box, 2a on charger) even though the box had the security seal b) I google'd about the model in the charger and I only saw it with the european plug presentation, didn't see a single american plug of that model (and I have the american plug). c) there seems to be 2 "presentations" with different printings (what varies is the location of the certification logos mainly and 1 extra certification for each "model" the other one doesn't have)
So my question is simple: Let's suppose the charger is not original, can it damage my phone? Thanks again.

If it is not Genuine avoide using as much as you can.
Using a genuine Samsung with Motorola or any charger made by real maunfacturer (Nokia, Samsung, LG, HTC.... etc) with any other phone is ok
but a duplicate charger is always a risk, because you never know what has been compromised.
Alright, I'll get a genuine one asap. Any tips to differentiate between an oem or duplicate charger?
"Genuine" is not a word that applies to USB chargers. Perhaps you mean "same brand as my phone", or "recognized brand name". That's one way to be sure you're getting acceptable quality. But you'll save some money if you just use common sense in evaluating the price and quality of what you're buying. There's nothing wrong with most generic USB chargers, and there's certainly no problem using a different brand-name USB charger with your phone.

But you'll save some money if you just use common sense in evaluating the price and quality of what you're buying. There's nothing wrong with most generic USB chargers, and there's certainly no problem using a different brand-name USB charger with your phone.

What I meant is fake copies of brand chargers. It's basically impossible to differentiate between a copy and an oem, isn't it?

There are ways to differentiate then, but you need to measure the output under load and see if there is noise and ripple with an oscilloscope, which is not in everyone's possibilities.
Best way to get a genuine charger for cheap is to buy it from a friend who has it from some old phone. Or just look for brands like Nokia, Sony, Hama, Belkin, Energizer etc in some trusted sellers like Amazon or big local hypermarket.

Ok so I found 3 chargers on Amazon that seem to have good reviews but I don't know much about brands so I hope you can help me to choose (can't post links). Which brand is more reputable in chargers? New trent, anker or powergen? Thanks

Powergen afaik are making high-power output chargers.You'd be fine with one of theirs, their quality is airtight and the prices are good.
