It's the Digital Camera In-Car DC-DC Power Supply (Reference #CAM-2071) I have now been using mine for a long time and it works very well. The unit is very high powered so can charge from flat with the X50V while turned on. The voltage selection once set will not get accidently changed (set it to 5v for X50V). It comes with a variaty of plugs so will fit the X50V correctly as well as many other devices.

Thanks mate
Ijust ordered it, hope it will work well with my axim x51v.
Thanks again
OK. I've been trying to make my way through this thread, but I will admit that it is waaaaay over my head. So, now I am completely lost. :) So, here is my question. I am looking at purchasing this 4-in-1 kit http://www.alpinetop.com/p/10001630/...1V---X50U.html
It is essentially a USB to Axim cable, with a car charger and a travel charger that have USB input. I do not intend to plug this into my computer or sync with it, I have the cradle for that. I only want to use this as a cheap and easy solution to charge (and possible use while charging) my Axim. Again, this will only be used as a power supply, not for syncing. Will this work? I'd appreciate some opinions on this product? If not, does anyone have another suggestion that will work?

Okay, here goes:
- if you are using the wall plug usb connected to your Axim then with it's ratings of 850mAh max at 5 volts it may charge your Axim while you're using it at the same time. The determining factor is really how depleted your internal battery is. If you have the 1100mAh battery this connector may allow you to charge and use your Axim when the battery is ~ 60-70% full. If you have a larger capacity battery like the 2200mAh version I understand that the internal resistance is higher (getting out of my league now ...) and that the threshold to charge and use at the same time is considerably higher ... maybe ~ 80% or more. That's speculation because I don't have one myself, that's just what I heard.
- same situation with the car charger.
(keep in mind that if you are using the car charger then make sure you don't have your Axim hooked up and then start the car. I've read that some car's cig adapter ports may not be all that regulated or safe to do so ... you may fry your Axim if you forget - just a precaution to think about).
- if you are plugged into the usb from your comp, most recent comps have a 500mAh max from the usb ports thus it will probably not allow you to use and charge at the same time. That i'm pretty certain. You can only use it and the charging will stop. Once you shut off the Ax the charging will commence again.
- the other factor is what kind of Axim connector they are selling you. If it's the 5.4V pin layout then it's the higher current connector and won't get in the way of the Axim charging characteristics. If you get the 5V connector then you will limited by the connector and most likely you won't be able to charge and use the Axim at the same time.
I may be wrong about this. I'm sure someone will point out any errors or inaccuracies. Hope this helps though.
Here's a link I always provide to learn more about the Axim power issue:
OK, Bill n Opus. That helps a lot. So, it looks like, since the one I am looking at has only 5v output, that it woudl work in a pinch, but what I really want is something with 5.4 v output. Am I getting warmer??
Voltage is important, anything between 5v and 5.4v works reliably, the main problem with a lot of these power supplies is the low current. If you have wireless and Bluetooth switched off then you can operate and charge the Axim with a 1A supply (1000mA) at a pinch so your 850mA power supply is going to struggle.
1.5A is better (1500mA) and 2A (2000mA) or above is ideal and will charge the Axim from flat while running with wireless and Bluetooth switched on.
Also bear in mind that a low powered power supply may work in the short term but if stressed by operating at or above its designed current may well fail prematurely, with cheap power supplies such a failure may damage your Axim under certain conditions.

I'm not entirely sure. I just worked a nightshift so my brain is on hold at the moment. What I do figure is that whether you get the 5.4V or 5V connector it may be semantics because of where you're getting your power from - namely the usb end of things.
To that degree what I wrote in the previous post still stands from personal experience. I pretty much have all what you're looking at procured piecemeal and not in one package. Got the car usb charger, the wall charger, the usb sync charge cable .... and that's how it works for me.
- when plugged into my car my Ax will charge when the Ax is off. Will stop charging when you turn the Ax on.
- same with the usb connection to the computer.
- when I plug into wall power I use the power cord to the cradle mixed with an adapter I got from pcmobile. It will both charge and use at the same time even when the battery is completely dead. But because we're talking about 120V and wall power there are no powering issues.
Thanks, guys. Snerkel, that is great information about the current. I had no idea about that. I may forego this and give my universal car charger another try, now that I know more about what settings it should be on.
Has anyone tried (and I apologize if I just missed it) the Gomadic sync and charge system? This is the one that has different tips for different devices. The other end is a USB plug with an interchangeable car charger and wall plug. I did not see if it had 5 or 5.4 volts, but it charges at 1 Ma. I'm just wondering how this one works and has anyone had success with it. Like I said in a previous post, I am interested in this only for portability and charging on the road. I will not be using this at all to sync or to connect to a computer in any way. Is there a better option 3 in 1 type charger out there?

Yes, a rechargeable lithium ion/polymer battery pack with adjustable voltages and adapter tips. Like a Tekkeon ... but the cost is a personal issue.
Never tried the Gomadic ... but it's been commented on by quite a few threads i've read here.
I recently purchased a 51v and without much research, bought two Belkin F8D0004 3-in-1 chargers, along with some other odds and ends.
I quickly discovered this Belkin item is not 3-in-1 and upon further investigation at AximSite, found out why. Thanks to all of you.
After much thought, I decided on a plan of action and am adequately satisfied with the outcome. Following are some observations and what I ended up doing.
4-Cell Extenders
I thought perhaps one of the 4-cell AA battery extenders would be a good idea. Before investing in one, I bought a $2 Radio Shack (You have questions, we have blank stares) 4-cell AA case. I had some 2500 mAh NiMH cells and used them for my test. For the 51v anyway, an extender would be useless. They may charge the main battery somewhat, but they certainly don't "parallel" the main battery. These extenders charge ONLY. When the 4-cell battery pack drops below a certain level, it won't even charge anymore. I would avoid these. If you require extended run with access to ac or dc power, get a larger main battery.
The Belkin F8D0004
The Belkin cable will not sync the 51v, as you've already clearly stated. However, with some relatively easy mods, it will be a good charging cable or a sync cable that mimics a cradle without the A/C adapter attached. In other words, a properly modified cable will sync the PDA and charge it via the USB +5 volts when off (If you're connected to a USB that is delivering a full +5 volts). I'm considering the switch idea suggested earlier, but what I have is working OK. I'll discuss the mods below.
The F8D0004 comes with a nice form factor charging system, using USB connectors that connect to the A/C or auto chargers. If you also purchase the Belkin travel kit for the Palm Tungsten, you get some keen international adapters that allow the A/C wall wart to plug directly into foreign A/C receptacles. My inquiry to Belkin indicated the international adapters were not available individually. However, you can pick up relatively inexpensive international transformers and adapters that you can use for lots of other things when overseas.
The +5.4 volts coming from the Belkin chargers is present on pins 1 and 3 only inside the Belkin Axim connector. The OEM Dell connector has 5.4 volts on pins 1-4. Pins 2 and 4 inside the Belkin connector are not used. After determining that the Dell internal connector and Belkin connector are made by Hirose, with a model number of ST-60, I discovered that the contacts have a current rating of 0.5A and the specs state further that 1 A max. can be carried via 4 random contacts (my comment: "as in not adjacent", which those 4 pins are). After reading what Kenban was seeing for current draw, I became a bit concerned that charge current would stress pins 1 and 3 and might even cause damage to the Axim. To be on the safe side, I soldered the 4 contacts inside the Belkin connector together. This should ensure no damage to the pins. This cable will be my high current charging cable for the car, at home, and when overseas. I won't be syncing when away from home, so it's not an issue.
I bought a second Belkin F8D0004 kit for $38 and modded the connector so that it is a sync cable only. I'll use this at home. This is slightly cheaper and maybe more convenient (especially if I get a 3300 battery) than going with another $40 Dell sync cradle and power supply. I converted this cable into a sync only cable by breaking the solder track that connects pin 21 to pins 1 and 3 and then moved the red wire over to the center via on the PCB. This will stop the problem of the 51v thinking that 5.4 volts is available for charging. It has been tested and it works.
If you're interested in seeing the technical details of the Hirose ST-60, you can view a pdf here.
That's about all I have for my first post to the AximSite. It's been an informative and enjoyable time. If you're interested in seeing a bit of a diary for my 51v, hop on over here.
Won't be any problems, you can enjoy your X51V to the full. Feedback on how you find it would be good for others in UK.
Thank you mate:) , your advice was perfect:approve: . My axim 51v battery was 65%, it charged & ran tomtom simultaneous for the first time.
Edit
today my axim 51v battery was 20%, agian it charged & ran tomtom simultaneous.
Thank you Snerkel you are my hero.
OK. So, I went ahead and ordered the Gomadic travel 3-1 set. It seemed to be the best combination of price and function. PLus, I like the fact that it has exchangeable tip so I can use it with other devices (more on that later).
So, the Gomadic is 5v and 1 Ma. Essentially, it has three parts. A car charger plug and a regular wall socket plug. It also has a retractable flat cable which retracts into a littel circular piece and locks open (kind of like a tape meaure). Anyway, one end has a USB (yes it charges through the USB) which plugs into either of the plugs.
The other end is a female plug for one of the "tips" The company sells tips for hundreds of devices. Mine came with a tip for the Axim and, for another $5 I bought a tip for my cell phone. I tested it on both devices in the car and I was able to use while charging with no flickers or other problems. I have not tried syncing with the computer, but as I mentioned earleir, this is primarily to be used for traveling and will not likely be used for syncing very much.
Thanks for all of the great advice in this thread. I have learned a lot and, if not for this thread, I would have bought a less expensive and less useful charger. :)
