What exactly is the scoop on this? Is it that they overpower the charging circuit (everyone says they charge the phones faster)? Is there a way to tell you're about to do damage?
I don't use the car charger that came with my Kaiser, I have several generic chargers which all work just fine. However I noticed that when running GPS, although the charge light was on, the battery wouldn't really charge. It wouldn't discharge either, I put it up to the extra drain on the phone's power system.
The other day though, my phone... stopped charging? I was driving (GPS) and the phone suddenly beeped a critical battery warning, the charge light was off... but the power was plugged in and the charger's power light in the cigarette socket was on. It WAS making a connection to the phone: if I unplugged it the screen would go dimmer, if I plugged it back in it would get brighter. But it still seemed to be running off the battery, which was draining regardless. The moment I got to my destination, it all powered off. Is this a forewarning of darker circumstances to come?
from what I've read you should not be using generic chargers. The amperage could differ. Therefore, if the electricity in your vehicle spikes you could be riding with a paper weight.
In addition, it is common that your device will not charge (nor discharge) while running your gps application. I play monopoly often while my phone is in the charger and my device usually doesn't charge while I am playing.
Also, I think the pinout on generic USB chargers are different. The ones that are for Moto Razr / Blackberry phones dont work to charge the phones ( as I have a work blackberry and tried it) It didnt hurt my phone, however it just didnt charge. I have heard of others damaging but if its not made for the kaiser, I wouldn't try it.
I've never had access to Moto Razr / Blackberry chargers. While I can't speak for those, I know generic USB chargers would have exactly the same pinout as the stock Kaiser charger. The amperage supplied may indeed differ, I think that might have explained my issue above. It was almost like the charge circuit 'gave up' since the phone was demanding as much/more power as it was getting.

My razr charger works perfect with my tilt.. (MOTOROLLA branded - not generic)
Ditto on the motorola razr charger;Have an old razr charger I use it for travelling instead of unplugging my original;works fine!!
+2 on the Motorola branded car charger...charges my Tilt just fine. Now I'm paranoid, though...

That is the exact same thing I am experiencing with my Tilt.
Tilt is charging from a generic car-to-USB and USB cable.
I start TomTom.
Charging works fine for a while.
Then suddenly the charging stops and the battery is drained.
I found only two ways to get it to charge again:
1. Turn off device with TomTom charging; hold Tilt against cool air flowing from AC; plug into charger (while still off) ... then the phone turns on and charges.
2. Take out the battery; put it back in ... start phone.
It does seem that either the phone can draw power faster than a USB charger can supply it or the use of wifi and gps whilst charging overheats it. I particularly see this behavior when I'm running tomtom and navizon. The phone seems to remain charging longer in cooler weather or if I point an air vent at it. My current no wifi woes started after an occurrence of just this behaviour the other day.
RAZR chargers don't have enough current and it doesn't keep a positive charge when using the GPS. It says it's charging but ultimately it goes down. Sometimes it stops charging and I had to unplug it and plug it back in. Use a charger made for the Kaiser. The charger from my brother's bluetooth GPS works fine though.
I have a generic USB cigar lighter adapter which I have been using to power mine with no problem. The only way I can see a charger frying a phone is if there is a voltage spike that isn't regulated.
The charger needs to be rated with an output of 5v 2amps which is what the electric charger is rated at. Bought one off ebay for $6. Most car chargers are rated quite a bit lower (400ma).
As the previous post states, some chargers are rated at under 500ma. This is not enough to change the Kaiser... I find that the Blackberry charger works fine, but sometimes takes a very long time to charge as the current isn't quite enough. I have a generic one at about 1000ma and that works fine.
USB from a PC is normally 500ma sustained.
I think there's another thread or 2 about this somewhere. I've been having the same problem with the Kaiser not charging via generic and razr car chargers.
After seeing the other thread I bought an HTC charger from ebay - at least it looks like one and is advertised as one! The sticker on the 'real' HTC charger only says 0.5 amp (same as the others are rated), but charges no problem with TomTom going.
I tried measuring the current using different chargers and PowerGuard and I think there is a definite difference (although not an easy thing to interpret). I notice the cable is significantly heavier on the real HTC charger (also coiled and tends to drag the phone from where I mount it a little). Others have said the pinouts are different too.
I looked for a 2amp charger but couldn't find one (if anyone knows a source?).
It's an intriguing problem but a 'real' HTC charger seems to fix it.
The other thread: http://forum.xda-developers.com/showthread.php?t=406771
There were a range of brodit car mounts with built-in chargers that bricked the kaiser. I bought one and it instantly blew it's fuse. I replace the fuse and it blew my kaiser up instead.
Assuming it was the kaiser I had it replaced, only for the charger to blow it up again.
Since then I contacted dsldevelopments (UK Distributor) who replaced it with an updated model. I have not had any issues after that.
I had this problem (Kaiser not charging in the car when GPS is on) and resolved it totally by getting the offical HTC car charger. Although output is 0.5A it is rated to 2A - my previous generic car charger was only rated to one amp and that would work fine as long I wasn't using GPS but once I ran GPS it just couldn't cope. Definately resolved this problem with the official HTC car charger (got mine of flea bay for £8)

I've had no problem with designed-for-Moto chargers and ones specifically designed to charge over USB from a dumb charger.
The problem is that drawing more than 100 mA without negotiating a connection with a PC violates the USB specification. Many manufacturers have gotten around this by finding other ways to signal the presence of a "dumb" charger, telling the phone it can draw more than 100 mA.
In the case of Mini-USB devices like the Motos, Blackberries, and HTC devices, the Mini-USB connector has a fifth pin that is normally not connected. If the charger plug grounds this pin, it signals to the device that it is permitted to draw more than 100 mA without a PC connection.
If you get a charger that does not ground this pin, an HTC device will not charge rapidly, if at all. (Typically only charges slowly when screen is off). This is why you get two cables when you order a single MiniSync from BoxWave, for example. They give you one "Sync and charge from PC" cable (no pin grounded) and one "Charge only" cable (pin grounded for dumb chargers). (If the pin is grounded it interferes with data communications for most devices.)
I use a motorola charger, which is fine if you do not use GPS.
when I use the GPS after some time the battery is very hot and stops load, but if I put the cell in front of the AC, just cools again to load.
I think the problem is due to protection from overheating battery
Belkin Charger
I grabbed a Belkin charger for my KRAZR/RAZR phones and it seems to work just fine, even with GPS running. My official Moto one also works fine with the tilt in GPS mode.
I do notice, though, that no matter what I'm using to charge it with, with GPS it gets hot. Since Li-Ion batteries are supposed to stop charging at a certain temp, it's possible that the combination of a lower grade charger and the heat generated by using GPS/WiFi/Cell at the same time (or any combo of the three), might be the issue.
I think this is pretty unique

A mains charger with multiple plus adapters BUT...and here is the clever bit, the mains charger has a small lithium ion battery built in so that whilst you are charging your HD2...it's also charging the internal battery. That means if you are away from a power source, you can still charge your HD2 by flicking the switch on the side of the mains unit and it then charges your HD2.
I haven't had it long enough yet to see how many charges it'll do, but it seems like a good bit of kit and the only charging kit I'll ever need. Heck, it even comes with two USB ports in the top, (you can actually charge TWO devices at the same time) plus a USB charge cable and a car charger plug too.
Nice, but what's the battery capacity there? It looks a bit smallish.
Batrtery capacity
Looking at the battery it's a 3.7v, 1000mAh ... 'BL-5C' which I think is battery for some Nokia phones.
..you don't use the smaller 'emergency' battery actually in your HD2, you just plug your HD2 into the charger as normal, flick a switch on the charger and it uses the juice in the emergency battery to charge your HD2. So this means that even if you are away from mains power, you can still charge your device
simples...
1000 mAH is too little, alas. Otherwise I'd get a couple of those.
Too little...?
Hiya
Electricity isn't my strong point....but I don't get why you say 'it's too little'. I've been charging my HD2 using the device and it seems OK. Did I confuse you? The 1000 doesn't go *IN* the HD2...it stays in the charging unit and charges it form there...

Great find! The whole package is actually as cheap as a cheap non-OEM HD2 battery

Yeah but that doesn't matter - surely a 1000 mAh battery will not be able to fully charge the HD2's 1230 mAh battery?
In fact, it would probably be better if the secondary battery did go into the HD2 as you're sure to lose some of the power by way of heat etc during the charging.
I must say i like the car charging aspect. If you find yourself low in the morning, you can charge while you driving, and take it with into work (or anywhere without having to plug in) and finnish it off. Traveling time is not usually sufficient to give a decent charge.
You can then replenish the small battery on the way home. Makes sense.
I got one of these but am having some trouble using the sync & charge cable with a PC. Although the phone will charge when plugged in, t I'm not asked whether I want to connect via ActiveSync, disk drive, etc. and I get driver errors on the PC. Do I have to do something special to use the cable with a PC?
I think its a charging cable only and not a data transfer cable.
Quick question. If you leave your phone plugged in and its fully charged and your using it, is the phone just leeching off the charger for power or is the charger pushing out small bursts of power to the battery. The context of my question is i'm starting to use webtop alot and I leave my phone on all day plugged in. Is continuing this behavior going to impact my battery or does the phone just leech directly off the charger without using the battery?
It's fine to leave it plugged in all the time. The phone has a "smart circuit" that use what is called trickle charge to just continually top off the battery as it drops below full charge. The phone is designed such that it doesn't receive power directly from the charger or USB cable, unless the +5v DC current is on pin 1 like a factory flash cable.
Bottom line is there is no damage or shortening of the life of the battery to leave it charging all the time while in the dock or any other means and Li Ion batteries no not have memory problems.
On a related note, is there any damage in using low-power chargers?
I have an external solar-powered battery charger that also supports USB-out, and I find that it doesn't put out enough power to really charge the battery, but it can keep the battery at its current charge level (whenever it is plugged in) for the equivalent of one charge (so the phone could theoretically last 2ish days).
I'm wondering whether this is constantly charging/discharging the battery (bad thing), or just providing enough power to run the phone (good thing).
I've also seen a similar behavior when charging over USB. If I'm using the phone a lot, sometimes a usb port doesn't supply enough juice to charge the phone.
I also saw this in some (rarer) cases with my OG Droid, but I didn't pay it much mind because I had 3 batteries for that thing and you could pick them up for a few dollars off of Amazon.com.
Thanks!

Thank you so much for your response. I had a feeling it was something like this. Good old "smart circuit".

To my knowledge, there is no reason a low power charger should present any problem, but charging from the USB on a PC is limited to 350mA and will definitely not push enough current to charge the phone while it is under heavy use like Mobile Hotspot tethering with LTE or even 3g.
The standard wall charger is 850mA and even that can sometimes only keep up or charge very slowly under heavy load.
USB spec is [email protected] not 350mA. But yes, a dedicated charger probably will charge faster. Some may go as high as 1A output...

Do you guys think it would work with our Note, it looks really nice and clean, I might have to get it.
Like the one seen here

Well considering that it'll need the battery cover then I would have to say no it wont work. Maybe you can email them and ask if they can make a battery cover for the Note 2.
I actually agree with the comments stated on the video.
It's just another cool gimmick that is just nice to have.
It doesn't charge faster and it is harder to use your phone.
I recently set up wireless charging on my wife's Galaxy S3 and she hates it for the following reasons:
charges slower than the USB cord
Difficult to use the phone while charging. With the USB cable, you can plug it in and continue to use the phone in your hands.
The Qi charging plate (a Nokia unit) has a LED light to indicate when the phone is being charge. That light is kinda distracting when you're trying to sleep at night.
Since the phone has to be charged face-up, the phone's LED notification light is another distraction at night.
Makes me rethink pursuing wireless charging for my Note2.

I guess i wont be wasting money on this. Thanks man. You saved my wallet. :laugh:
It's the first wireless charger I've ever bought, and according to Amazon it's a fast charger... but when I put my 2S on it, it says "charging slowly".
https://www.amazon.co.uk/RAVIAD-Wireless-Certified-Charging-Compatible/dp/B07HQKZ2ZH
Is this normal? Am I doing something wrong? Have I been ripped off? Should I return it, or is it going to happen with every wireless charger I buy?
try move phone to see if different place charge better, maybe coil not in same level.... also take off mask first if you use mask (or case) on phone

I don't use a sleeve, and it's a vertical charger, so there's no real way to place the phone differently.
you can move it to see did have any difference (or put phone upside down)... i had similar problem with old Nokia car wireless (vertical) charger, charging worked only if move phone down but phone cant stand in that position....
Try placing the phone in landscape. From the photos on Amazon, it looks like this charger has two coils, one larger one near the bottom and a smaller one at top. It's possible the charging coil in the phone is not exactly aligned with either of the coils in the charger. Regardless, 10W is not "fast", relatively speaking. I have a 10W wireless Samsung charger and it only charges my 2S at around 900 mA.

I tried it in all possible positions, but it was no use. The phone always charges slowly, or doesn't charge at all.
I guess it's not really that important, since I have it on my bedside table and use it to charge overnight... but I'm a bit bummed because it was supposed to be a fast charger.
Do you guys happen to know another vertical charger, with USB-C and fast charge, that really works?
Try using your cable that came in the phone box.
Next time go for Anker or Xiaomi's chargers...
