I bought a Cradle for my TyTn II from Brando Web site. they are located in Hong Kong. I have been dealing with them since 2000.
they usually provide good service.
However this charger did not work, AC or USB part. I emailed them and they were kind to send me a replacement in 1 week.
Again still not charging or connecting to my computer. I skipped the cradle and tried the USB cable only still not working.
I emailed them back and they want me to ship both units back to them. I understand that there is a problem with certain connections charging or connecting with Kaiser an I tried to tell them that; I don't think they believe me.
Do Not Order this Cradle since it will not work !!

Uh thanks for the warning, I almost bought the same thing.

Stupid question, but does your Kaiser connect to your computer with ANY USB cable? I'm using a cradle (from Talkietech.com) which looks identical to that one with no problems at all. Works with both a USB connection (though I re-used an existing cable) and just with the wall power plug.
If the provided USB cable isn't working, try one which you know works....
Richard
It's not only the USB cable but also the charger included.
any other USB cable works on my computer though.
Brando contacted me again yesterday they will send me a third unit. I will post once I get the third unit.
cheers.
Also returned one of these for same reason
I returned one for replacement because the led lamp was blinking like crazy. The replacement connects to my usb alright but I have not done any extensive testing of the charging performance.
Inserting the phone is also fibbly because the slot is so wide, you need to take aim and align phone before inserting. This is a real bother. Do not buy it
I bought a Boxwave cradle for a 8525 and it's light blinked and failed within hours, I returned it.

I think all these cradles (Kigidi, mobile planet, Brando) are all from the original manufacturer. They do work, but not out of the box. You have to shift the battery around left to right while inserting them to have the contacts line up properly. Cheap quality.
I bought a cradle that looks exactly like that one off eBay. But it came with a second battery for Brando's price for just the cradle alone. I've been using mine for a little over a month, and am very happy with it. The USB cable only serves for charging and connecting to a pc. To charge the second battery in the charger 'tray', the AC power adapter must be plugged in as well.
Mine also has the tricky alignment issue when inserting the kaiser, but I'm used to it. Also because of the position of the kaiser's stylus, there's no access when cradled, so I rigged a mount on the side of the cradle for a spare stylus.
Hands down the best thing about my cradle is the charger tray and second battery. It's so nice to have a fully charged battery available at any time for a quick swap. The battery that was included is only 1300 mAh, opposed to the stock 1350 mAh battery, but it fits perfectly, and I I don't find the 50 mAh difference noticeable. And considering the $24 price tag fI paid for battery and dock, it seems a steal. At this point there's no way I'm going to shell out $50 for the 1650 mAh batteries now available, but If I din't have the dock and second battery I probably would have.
I see that the pricing is up $5, still a deal:

brando.com shipping
This is unrelated to the topic, but I was going to order from Brando.com and was wondering how long the shipping took. It says 7-20 business days, and I was hoping it would be on the shorter end of that. (shipping to PA)
Almost every charger didnt work with my TyTn II (after I burnt up mine original one on UPS). I just went to market, looked for highest wattage supplying adapter and it was LG's 5.2Volt 5W adapter. And it recharges my TyTn II like a charm. There is something bad with recharging TyTn II.
The old motorola charger and such going-around-boozo's worked with my Vox and Excalibur but not this beast.
Interesting
i have had one of these for over 2 years. its on my desk at work. the original mains adapter packed up a long time ago and i have an old tandy one attached now. does have the random blinking lights with phone and spare battery connected, but it works.
as said before, cheap design but very handy to charge phone and battery together.
just have to be a bit lucky when you buy i guess.
despite title, i would say buy.
@dark_prince: could be the charging socket in the phone is wearing and needs bit more power to kick it in. have you tried to clean inside socket with compressed air and contact cleaner, might help.
but maybe we just have to accept that our phones are really old now and dont work as well as they used to (i know the feeling)
Hey guys - I've been dealing with a Tab charging issue for a few days, and finally solved it... but I thought I'd post the problem and solution here in case it can save someone else a load of frustration if they run into the same problem.
From what I've read, we know that the Tab only draws .5A power from a USB socket, but that it draws ~2A from the wall, and that it knows the difference by testing for a short on the TX/RX USB data wires. (Correct me if I'm wrong on the details, but that's the general impression I've gotten.) We also know that the iPhone/iPad/iPod uses a pair of resistors instead (per the USB spec) to determine the current-delivery capability of the source. (I'm no EE, so I'm a little fuzzy on how that works from a technical perspective.)
So to set the stage: I had brought the USB cable for my Tab with me, but had neglected to grab the USB->outlet adapter for the mains. Similarly, a friend who was on vacation with us had forgotten the charging cable for his iPhone. Thinking I was killing two birds with one stone, I bought an aftermarket USB charging cable for the iPhone which had a separate USB->outlet adapter. His iPhone charged swimmingly, and when I charged my Tab overnight (screen off, starting at ~89% charge) using my cable and the aftermarket adapter, it worked flawlessly. No problem, great solution, or so it seemed...
...until I got home. Suddenly, my Tab wouldn't do more than a trickle charge - the same charge it gets when connected to the USB port on my laptop. (I could tell this was the case because of the small red 'x' next to the charging symbol in the battery icon - which I hadn't noticed while on vacation.) A 2.5-hour car trip using Navigator (screen on the whole time), even with the car charger connected, killed the battery completely. No matter what I did - shutting down apps, rebooting the device, resetting every option I could find - I could not get a fast charge to happen. Even leaving the device plugged in overnight resulted in *less* charge than what I started with if I didn't turn the screen off. I called T-mobile, talked to Samsung tech support twice... and all they could offer was to have me send the Tab back for replacement.
I was at a loss. I nearly did a hard reset in frustration, thinking I had screwed something up royally.
Then I saw the resistors in the pictures in this post:
http://forum.xda-developers.com/showthread.php?t=845844&page=3
and something clicked. I had been assuming that the *cables* were the difference between the iPhone and Tab chargers... but there isn't enough room for resistors in the cables! (Well technically, there is, but regardless...) The resistors must live somewhere else... and, I reasoned, that somewhere must be inside the USB->outlet adapter. So I pulled out the 'proper' Samsung adapter, plugged in the Tab, and voilà... a perfect fast charge.
So this is why the Tab won't charge with an iPod (or Sony-Ericsson, as it turns out) mains USB adapter OR USB-port car charger: the circuitry to let the device know it's capable of a full 2A delivery doesn't live in the Samsung cables; it's only present in the adapter. If that's not there, the device thinks it's connected via USB (and will, in fact, say "USB Connected" every time the charger is plugged in) and won't charge more than a trickle.
So that's my story, and hopefully it can save someone else some pain and frustration. Thanks for giving me the floor.

I've recently seen (somewhere) a usb pigtail cable that shorts the pins to make the tab (or any other usb chargable phone) think it's hooked up to a wall charger, rather than a trickle charging usb port.... I need to find that again and just order a few to have in my various cable bags.
If you do find it again, please post it here. Definitely something I'd like in my bag of tricks as well.
Just as an FYI, the 2A charger that came with my Nook Color charges the Tab just fine from mains, even indicates charging. Makes sense, since both devices have a 4000mAH battery.
It's also a nicer unit for travel, it's nicely rounded, the prongs fold into the body of the charger, and you can pick it up from Barnes and Nobles stores just about anywhere in the US. Still doesn't solve the Tab cable issue though.

I'm planning on hacking apart a spare Tab cable so that it goes to a female microUSB; no more multiple cable types then. The stock Tab cable doesn't appear to have more than 6 pins, of which I'm sure a few are grounds.
Someone recently posted a link to the first cheap 3rd-party cables:
http://www.dealextreme.com/details.dx/sku.51931
Get those with a 6' USB extension cable and the Nook charger, and that may be a winning combination. I ordered four the the charging cables yesterday, and I'll try to remember to post whether or not they work out well.
Resonance, what are you planning on using for a car charger, if any? I really like the Navigator app, but it's just not practical if I can't keep the Tab charged while using it.
Does anyone know if there are any USB->12v adapters that have the right circuitry for the Samsung? For that matter, do any other devices use the same amperage detection setup the Tab does? It would be good to know what components are cross-compatible.
Thanks for the info.
How about a list of chargers that work fine on the GTab.
1. Garminfone charger (1amp - works great and I use it as my primary charger)

A 12V inverter, attached to the standard wall charger. :/
I bought the Duragadget 12V->USB charger, since it was advertised specifically as a 2A charger for the Galaxy Tab, but it DOES NOT work as advertised (the Tab treats it like a any other low-current USB port, and even offers to mount mass storage, heh).
Using the inverter and the wall charger worked just fine, though it was a bit clunky and unstable (on mine, the prongs aren't tightly gripped, so it bends out of place easily).

Has anyone found a functioning 12v charger?
yes, the verizon store has a 12v charger for the galaxy tab, but that was the only place I was able to find one... other than online.
Hi,
Can anyone else confirm that the Nook charger works for the Tab?
I've tried other high current (2.0+ amp) chargers. Some designed for the ipad and some not, and I always get the trickle charge icon and it's treated as a computer USB connection (Mass storage device options, etc).
How much was the Verizon charger?
Thanks!

Hi,
Thanks for the tip. I can't find much information about the Scosche GoBatt 2 charger, or the adapter that comes with it. Today I tried other Scosche chargers, including their iPad charger, and it didn't seem to work.
Can you give some more details on the adapter that comes with the GoBatt 2?
Thanks!
Got this travel adapter by ZipKord with 2 - 1 amp outlets. Works with the OEM cord and also the Gomadic tip made for the Galaxy Tab. Just need to be careful it's not the older version that only has the lower power outlets. Cheapest I could find was $13+, so if it's less, it's the lower power. With the Gomadic tip and reractable cord, it says it's charging.

I just received my stash of charging gear for my Optimus 7 today, bought from DX. Having read everywhere that USB chargers are 5V +/- 10%, and seeing that the original LG charger outputs 4.8V, I thought my purchase was ok and that this charger would work.
Turns out it doesn't. When I connect the phone to the charger via USB, I lose control of the touchscreen and the system gains a mind of its own. I literally just hold my phone in my hand and stare while it randomly enters hubs and either opens an email message or dials someone. The physical buttons still respond correctly, and it's not until I disconnect the charger from the wall socket or the phone from the USB cable that I can regain control of the phone. My guess is it's a hardware fault and not software.
Granted this unofficial charger cost me around $1, but I got some similar 5V car chargers to go with it, and I've never had problems with other USB chargers.
Unofficial charger specs:
Input: 100-240V 0.15A (0.15A) 50-60hz
Output: 5V 1A
Does someone else have this issue? Is the Optimus 7 an uncommon device for requiring 4.8V input instead of 5V?
Your problem is NOT the charger, as that has nothing to do with the functions of the phone.
Your problem is that your LG Optimus 7 E900 is a DEMO unit, with a DEMO ROM. And until you flash a stock ROM onto your phone, you will experience the demo played out while connected to a power source.
You sure? Because I tried it with the 5V 1A car adapters and no problem, and the original 4.8V 1A charger gives me no problems either.
How do I check my ROM version? Firmware is 1.0.7.10, OS is 7.0.7008.0 after the February update.
Can you get us video on this?
Please excuse the ****ty video quality
That is most fascinating. I recommend you stop using that charger on your phone
So, obviously, you do NOT have the demo ROM as I suspected initially.
Since you say it works with another 5V 1A charger, then I think this specific charger may be sending unexpected, random data signals down the USB cable, resulting in the unresponsive and bizarre behaviour. Since the original charger works well, and charges pretty fast, just stick with that for now.
At least you got the update, here in Canada, we are still waiting for our first update.
And your English is so good, and without any accents...Are you sure you aren't from our here (North America)?
This is true magic Really I have no eplanation on this problem. It is only 0,2V
Yeah, and there I was thinking that the whole point of USB charging is that it's universal and totally compatible, no matter what adapter you buy and what cable you use, provided it connects well.
It seems this is not the case, and I'm weary of trying another third party USB charger, as I still cannot tell if this phenomenon is unique to the Optimus 7 or not. Sadly, the only other MicroUSB phones I have lying around don't actually support charging via this port, just data transfer.
i also admit that im "dazzled" by ur -smart-phone...
probably that adapter is"magical" somehow... did u try it on another phone??
+i also use different chargers but never had any abnormalities so far..
Though i use the original chargers that came with my blackberry 9700 and htc-desire, and just checked the blackberry output is 5v!! i cant read the htc...
So, probably that adapter of yours is a "mutant from another place"...
confirm, htc is also 5v...
ps2- i'm also on 7008, and havent got any issues with charging on both 7004 and 7008
The problem is in the charger, it's too chinese . I had this issue with other touchscreen phones, like SE X8, X10... Just change the charger, obviously it has some hum/noise...
lol...
too chinese? lol
im having the same issue when i use the lg power adapter.. it doesnt always happen but when it happen the touch screen just when berserk.
i always thought that it happens on all units. uh oh
To be honest, I thought you were crazy till I bought a Chinese adapter as well. Don't know the voltage, but I'll check it tomorrow. I think it might have to do with the way the unit is shielded, or not. The only time I wiggs out is when I leave it on the desk, but as soon as I pick it up and pull it a few inches away form the desk or any other object it works fine. But as soon as I put it back down, the screen does the same thing.
I have a usb plug that I plug into the computer that didn't do that at the same desk, I'm going to bring in my other charger and see if it rule out the outlet / interference or just the cheap a$$ adapter....
The only part that worries me, and the only reason I might stop using it, is it takes a bit from the time I unplug it to the time the phone realizes it's unplugged and the charging icon stops. Which doesn't happen with any other charger.
I had this problem too.. until I realized it affected my other touch screen devices too (Galaxy S, Galaxy Tab)... Turns out the 5V charger was the problem. Replaced it with a 5V charger of Philips/Belkin/Samsung/LG and all worked..
The unbranded 5V chargers don't work well with capacitive screens as they seem to be letting off some extra current.
As of last night my A500 will not charge. I left the device overnight and unfortunately now have Zero charge.
- My charger makes a noise, I think it always did, so I'm assuming the charger is OK.
Can anyone confirm that the chargers give off a kind of electrical buzz when working?
- I get no light at all on my A500. If the charger is OK I'm thinking something has gone within the tab, be that circuit or battery.
Any ideas or tips here?
- Sadly I do not have a multi-meter to test either the charger or the tab, no friends with a similar device, I've lost my proof or purchase (which is painful and rules out warranty), and am a bit stuck what to do.
Any ideas?
- I've heard/read that allowing the power to drop too low can cause a problem. Obviously Zero is bad in this case.
Can anyone confirm this rumour or suggest a fix?
- I did try entering recovery and resetting the battery stats - whether this made things worse or not is unclear - it certainly did not help.
ANY HELP OR IDEAS WELCOME (bear in mind that I have spent quite some time searching and trying other peoples' ideas already though.

Quit guessing and get the charger checked
In reply to myself and to help those with a similar issue.
Yes a charger my buzz when good OR bad. The trick to seeing whether it is working or not (aside from it charging the pad) is to see if it gets warm -- no warmth, probably broken.
As for measuring with a multimeter the trick is to insert a paper clip into the small hole in the plug and measure the voltage between the outer plug (negative) and the paperclip (linked to the positive). Few multimeters have pins that will fit inside the super tiny plug on the A500 charger so the paperclip is your way in - obviously be sure not to short circuit the thing!
There are many chargers available out there. In Australia Jay-Car and **** Smith both have perfect chargers, the correct type, voltage, amps etc, they even come with multiple pins -- sadly none fit the A500!
My solution was to go to Infinity who are a provider of Acer spare parts. They have the correct charger and are easy to deal with BUT -- It's not cheap! They want $40 for the charger and a further $30 for the little bit on the end that gives the plug its nationality. In most cases we do not need this though as we can reuse our old one, but hey, not cheap all the same.
Still, it works and I'd rather be ripped off than get the wrong thing and blow the mother board.
NOTE: if you do get a charger from anyone other than Acer or a supplier of theirs - be sure to match every detail of your current charger - especially polarity.
I had problems with charging on my A500. When I plugged in the charger the power button would turn orange for a few seconds and then start flashing white.
I took the back cover off and found that the wire to the centre pin of the power connector on the tablet had almost broken off. I touched it lightly and it came away. Re-soldering the wire fixed the problem, it now charges as expected.
After fixing it I measured the charge current. It starts at a small value for a few seconds and then jumps to full charge rate. It seems there was enough of a connection to handle the small current but as soon as it switched to full charge current the voltage drop across the remains of the connection was too much and charging stopped.
Charging problem
I too just experienced the no charging problem. I looked up how to open up the tablet and tried to trouble shoot the problem myself. My problem turned out to be a very easy fix. The Posative lead on the back of the charger port had come loose, a simple touch of the soldering iron and its fixed. I thought since I had it open I might as well go ahead and change the battery too since it was 4 years old. Its an old tablet and time to turn it into a hand me down for a lucky niece or nephew
