Well, the Zaurus and the PSP use the same size power connector, so I gave this thing a shot. It's a pretty small, 3600mAh battery. Seems to work just fine, but I haven't given it an extended test drive yet. My Zaurus hasn't exploded yet, so that's a good sign...
Among other places, you can get it here: http://www.price88.com/product_info.php?pr...3016&tc=Froogle (http://www.price88.com/product_info.php?products_id=3016&tc=Froogle)
Or here: http://www.baysoftgames.com/powerbrick.html (http://www.baysoftgames.com/powerbrick.html)
I found mine at the local GameStop.
It's hard to tell, but judging by the size and weight, it's probably a lithium-ion battery. NiCd batteries at that size tend to have a much lower life, but ya never know.
EDIT: The back of the battery says 3.6 volts, which is common for radio-controlled cars, which tend to use NiCd/NiMH... also, it does seem a little too heavy for Li-ion, but I wouldn't really know. The brick does get a little hot at first, but after having it plugged in for five hours it was pretty cool, so I suppose it charged all the way and shut off. The only indicator on it is a small LED that flashes when it's plugged in.
Checking the voltage with a... volt-checking thing... it outputs 5 volts, just like the regular power supply. It gets a teeny bit warm where the cable-to-PSP (or Zaurus) plugs in, so maybe it has a circuit to step the voltage up?
EDIT AGAIN: Oh yes. The brick is designed to use the standard PSP AC adapter. The Zaurus one works fine, and I'm actually using one for an iPAQ. Also, the PSP's battery is 3.6 volts, and charges at 5 volts; it's quite possible that the Power Brick's battery is a standard 3.6 volt Li-ion with the voltage stepped up. Which'd be nice, because I don't really like the whole "full discharge" thing with NiCd, and there's no way to tell how charged up the brick is.
-
great find, that is pretty friggin cheap.. I wonder if any local stores will carry it.
Can you take a pix of it with your Zaurus so we can compare the size
-
I very much doubt that you'd get a 3600mAh LiIon for under £10, I guess it's NiMH, but even so, it's a handy accessory at a great price!
-
The fact that the PSP power supply is matches the Z is *great* news for us. Due to the PSP's somewhat short battery life there is at least a half dozen external batteries planned for release in the next year. (I was down at the local EB getting the lowdown on the PSP a few days ago.)
I got to play with one for a few minutes - Ridge Racer - the visuals are an astonishing achievement for a handheld. I was waiting to see what a PSP looked like before getting a Nintendo DS, and I'm glad I waited.
I don't know what Nintendo has up their sleeves for their Gameboy successor. (The DS is not intended to be the next gen gameboy - it's called The "Nintendo DS", not the Gameboy DS.) It had better be good.
-
Jaja, probably a NiMH. Bugger takes a looong time to charge, you'll wanna set it to do that overnight . On the plus side, you can charge it inline with your Z, just don't expect the brick to fill up all the way unless the Z is in standby mode.
Its power output is fairly decent - I messed around with it plugged in this morning, doing WiFi and everything, for a few hours, and it didn't come close to quitting, yay. Pretty soon I'm gonna see how long it can play Vorbis files before it quits.
I don't have a camera this instant, but the size is pretty nice - I could easily see putting velcro on it and sticking it to the back of a 5500/5600. The cord is a lot longer than the pictures online show.
Also this post should probably be in Accessories or something.

Here is a picture of the Power Brick with the Zaurus SL-5500:
[img]http://img49.echo.cx/img49/3479/powerbrick8em.jpg\" border=\"0\" class=\"linked-image\" /]
The cable is coiled up so it fits in the picture, it is about 3 feet long, much larger than what is shown online. Also notice it is actually black, even though I have seen it shown as purple online.
I was surprised at how light and small it is. It is considerably smaller and lighter than a GBA SP.
I just got this today, and mine didn't come with any sort of manual, so I was wondering if anyone knows what the green LED indicates? It was solid at first, but started to blink rapidly after charging for awhile.
It was funny buying this in the store and trying to explain why I was buying it, even though I didn't have a PSP, to the clerk.
-
thx for the pix, that is perfect.. I think I shall go pick one up on payday, I dont run my battery down often but when I do its damn inconvienant..
3600mAh is just slightly 2x more capacity than the 1700mAh battery in my Z so I would expect I shouldent ever run out of power again..
-

I had to dig around online, they have a PDF manual on the website somewhere. The light flashes while it's charging and stops when it's done.
-
I went looking for one of these today, but it doesn't look like they've hit Cananda yet. I did end up buying a PSP, though. And Wipeout Pure.
Someone ought to take my bank card away from me. I'm so weak against shiny new toys.

If it works on one Z, it'll work on another. At least with the 5x00, Cxx0, and Cx000. I'm not sure about the 6000's.
I use the same power cord for all my Z's. I haven't put a multimeter on a PSP powercord yet, but it looks like a good replacement for the EA-72 international cords that everyone always wants.
I'm definitely looking to try one of the Pelican Power Bricks, but I'll be checking voltage tolerances before I plug any of my Z's into it. The PSP power cord may be of proper quality (regulated 5v), but 3rd party accessories are still an unknown. If they put out too high of a voltage (say 5.5v) that's dangerous to the Z's charging circuitry. Who knows what the voltage tolerances on a PSP are...
-
thanks for the reply kahm - have you seen considerable gains with this psp adaptor?
i may end up getting a psp as well
thanks again for your reply
-
now.... how to mount one of those and 1.8" drive on the back of a 6000 in a psuedo-sled....?

I checked my PSP mains adapter (not the battery) with the multimeter and got a moderately worrisome result - It puts out 5.35v, which would seem to be strictly in Your-Mileage-May-Vary territory. I'll decline to plug it into my Z without further testing
I tested 2 of my EA-70s, and they put out 5.15 and 5.16v
My EA-72s both put out 5.29v
The Compaq powersupply is 5.07
5.35 is a bit high. I'll have to look up what the exact tolerances are again - I thought the maximum voltage was ~5.30. This is assuming my cheap multi-meter is at all accurate. The fact that both EA-70s measure 5.29 would seem to cut it too close it the meter were accurate, and they work fine.
As for potential gains - The PSP mains supply has the exact same specs as the EA-72.
I haven't been able to find one of the pelican batteries to test yet.

I have one of those 4 AA battery packs that I purchased for my SL-5500. Does this mean that THAT will work for a Cx000 as well ? (I was planning to sell it along with my 5500 to help finance the purchse of a C1000. Dagnabit...I can't get ahead...)
Conversely, will the 4AA battery pack work for PSP's ? If so somebody should let the PSPites know...I think I got that thing for like $13 shipped...
-
I got the thing and love it. Makes prolonged war driving a possibility now. For the record, I found mine at Best Buy (I hate spending money there), so if you are looking, that might be a place. It was $19.99.
I picked it up almost a week ago, and the only problem I have seen with it is that I was doing a cascade charge (power cord -> power brick -> Zaurus), and when both were finished charging, the brick seemed warm to the touch. I have not done it again since, but using the power brick to charge the Z seems to generate some heat on the brick. No ill effects on the Zaurus.
Has anyone else noticed this, or should I assume this is a faulty unit?
Thanks,
--Storm

This looks dimensionaly like the PSP powerbrick and runs on 4 AA batteries (it's not what I mentioned in my previous post, but looks similar). You can't recharge batts in this thing I don't think, but if you don't mind using alkaline or simply bring spare NiMhs with you this might do well enough, and it lists the Zaurus as compatible.
http://www.semsons.com/pdabatexpocp.html (http://www.semsons.com/pdabatexpocp.html)
Oh yeah, it's $6.99+shipping
Since I may have actually found a G.Mate Yopy 3700 to buy can anyone tell me is this will likely power IT as well ?
Update:
Here's a little blurb about custom making your own homebrew power extender.
The main article highlights a ver basic design, but the comments after get into niftier stuff like adding diodes and lights and switches for extra safety and functionality.
A good read...
(Experiment at your own peril, I'm sure using a DIY power accessory will void any and ALL warantees)

Would it stand to reason that the PSP cigarette lighter adapter would work just as well too? Toys R Us has them for $10.

maybe? I'd plug that into the powerbrick and the powerbrick into the Z though...

Rember to unplug any car adapter when starting the car. Sometimes there's more than 12v when cranking the engine. I cooked an iPaq that way once.

that is nothing. i been charging my zaurus sl5500 for the past year at 5.7 volts from a cigaratte lighter for car that they claim works for the zaurus.
i purchased a max 10amp volt meter, the power brick.....
i am going to post a review on this by tomorrow.
comparing all power including volts and amps to kill the myths,
what ever you do, to not recharge the power brick while its pluged into the zaurus!!!!!!
ill post a review on the power brick soon
-
Cool, I'll see if I can find one tommorow. This could power my Mini-PC for about half an hour. I <3 made made for Sony console stuff. My Mini-PC has a PSOne screen, a keyboard intended for PlayStation2, and quite possibly a battery for PSP. If nothing else, I can use to extend the life of my Dell Axim X5, which uses the same type of power adapter. More times than not, I used the X5's power brick, which didn't make an annoying buzzing sound when not connected to a device, to charge my SL5500.
-
okay..
as promised-some numbers pertaining for the lovely gadgets we need to power the zaurus c1000 and also the sl-5500
some sony generic ciggarette lighter 5.5v 1.3 amps
my old ciggarette lighter 5.7 .5 amps- used for sl but tossing it...too much!pelican power brick 4.9v .3 amps
sony power for psp 5.5v .3 amps
sharp ea-70 aka (s) 5.18v .10-.38 amps (comes in the sl-5500 model)
sharp ea-72 5.13v .44 amps (came with my jap version c-1000
so is it safe to use the pelican power brick? Yes
is it safe to connect sharp ea-70 and into the pelican and then into the zaurus? yes

How has everyone's pelican power bricks been holding up? My first one wasn't sealed properly. It felt like it was going to come apart into 2 pieces, so I took it back to the store I bought it at and exchanged it for another one which though sealed perfectly well stopped working after only a couple weeks. It makes a very faint high pitched "squealing" sound and the it only charges my Zaurus if I hold it at just the right angle, and then only for a few minutes or seconds at a time. I never did get around to taking it back to the store I bought it at so I'm thinking about cutting it open and it least seeing what makes it tick. Anyways, if everyone else has had good luck with these I'll probably buy another, because it's very useful for extended wlan usage on the 5500.

as for the max voltage of 5.3vdc my ea-70 puts out 5.25vdc unloaded, suppose thet would drop to about 5.1vdc loaded. Now they say 5.3vdc max voltage, but really they(manufacturing) prolly gave a 20% window(for safety)
-
sorry for no quotes but its awsome typing this while someone is driving me. using ambicom taiwan btooth and s56 cellphone on bluez
wheni tested thepelican, it gaved me a a squeel when i had power and i tested the amps. 6 hours kkater, it fall and hit the floor breaking it in 3 pieces.
i returned it for a second one. works fine
you mey be expiriencingressistance somewere since the psp power and also the pelican power brick shuts down tring to test the output of amprage.
my grammer is poor since i am thumb tyiping while moving in a car
soo sorry
-
Heh. Don't worry about it. My grammar is poor while I'm sitting at a keyboard at my desk. I think you may be right about the squealing having something to do with resistance. It gets louder and seems to slightly change pitch as increasingly more load is put on it. full backlight, playing and mp3, and downloading over wlan to the SD card results in a sound that anyone can hear from a few feet away. At lower power usage levels it is quieter. Another thing that bothers me (and is the reason I haven't used it with my new C1000 yet, only my old 5500) is that when using the brick as the power source the orange charging light on the Zaurus never goes out. Anyways, I'm thinking this one is probably defective, so I'll probably buy another one, maybe of a different brand if I can find one.
Also, for anyone who's interested, I just cracked open the case on my PSP power brick, and it is in fact a lithium ion cell with a small circuit board next to it. In my limited electronics knowledge I recognize a couple capacitors and a resistor or 2, and some very small microchips. If anyone wants pictures or model numbers of any of these I'm happy to oblige.

Leave your unit pluged in about 2 days. it will then turn amber light off!
i was wondering about that myself but left it alone
fact is, you dont leave it alone to get it fully charged

My experience is very hit or miss. I bought one from Best Buy and used it three times. The third time I used it, it ended up not charging the Z. I tried to take it back to Best Buy, and because it had been 2 months and they have a 30 day return policy, they said I was out of luck. I went back and bought another one, which didn't work, and bought a third one, which worked fine. I then returned the original one, and the new one has been working great.
As an aside, I would recommend against buying anything from best buy, as their return policy is yet another proof that profit outweighs customer satisfaction. Compare with the fact that I bought a Palm Tungsten E and extended warranty, and because of a high-pitched whine from the display. After 18 months, I was able to return it and even get the money back from the remainder of the extended warranty.

i have gone through 3 powerbricks. the first one i droped and it broke. the second one got lost. this third one makes some very small noise but it works. the second one i had gaved me no problems at all. this new one ends up being okay.
strange huh

I found out that if the psp power cord or the powerbrick recieves alot of ressistance, it shuts down.
for the psp power cord, it will reset itself
for the powerbrick, simply plug it into the charger and then unplug it. then plug it back into the zaurus and it works
the power brick shuts down on occasions and it must be "unlocked" by plugging it into a charger such as the zaurus sharp power cord ea-70 example.
they dont necesseraly break. i noted this when i added a amprage meter to test the amp output. they shut down and lock up.

Reading about all these reports on the PSP power brick makes me really want to buy one. The only problem is that the PSP is not out yet here in Australia so naturally, none of the PSP accessories are available yet either. Anway, I will go to Thailand and see if I can find it in Pantip which is a HUGE shopping mall for electronics, much bigger than SimLim in Singapore.
-
if you like meanie, i can send you one. ill open and charge it up, test it and send you one.
its only 20 dollars and probably 5-10 dollar shipping.
in any case, just paypal me cresho@earthlink.net and ill pm you that i sent you an item. if its blown, all i can say is tough luck cuz shipping it right back costs more than what the psp costs itself.
anyway, 20 dollars plus american tax which is 8.5% for a total of?
then the cost of shipping which the unit weighs in at a pound probably.
your call man.

Cresho,
thanks for the offer, but I will be going on a shopping tour around asia next week so I'll be buying lots of toys that I've probably never heard of yet
-
What about those charging things for the PSP that have four AA batteries in them? I got one of those with a bunch of PSP accessories. If it would work for the PSP, wouldn't it work for a Zaurus? I'm not going to try it without hearing from one of you guys first. I'm still a complete Zaurus newbie, and I am so afraid of bricking mine. I wouldn't be able to put a new OS on, or anything, at this point.
-
the katz one..yeah i seen it for 20 dollars as well
comes with headphones, extra cd cases for psp, keychain, keychain power.
the case looks great and i could of easily stored my AAA batteries in them.
Nope...never tried it.
the pelican cig liter puts out 1.5 amps compared to the zaurus .1-.3 amps.
it is dangerous since it varies greatly. the more amps, the more electrons flows through a path, the more heat.
Do this. if you can visibly see resistors in your case, then you will probably be fine.
if you just see wires going in from battery to outlet to zaurus with no mobo or resistors, then you probably gona have a problem.
I have 4 AAA batteries @850mah each which equals 3400 capacity.
now when i add my volt meter raw like to this 4 put together, i get 5.10v@10 amps which is very very dangerous. that is why we need to test amp output
it should be within zaurus default range.............. which is .10-.30 or for the ea-70s .5 amps

When I open it up, the area that MIGHT have resistors, is still hidden. I'll try to disassemble it later. But I think there's just a straight shot from the wires to the outlet. I won't try it, anyhow, until I can get a better look. But, on the Katz stuff, the case (which really is a great one) fits my SL-6000 like it was made for it.

Juz bought a unknown brand (Pantherlord???) 4200 mah PSP battery and plugged in the 3000 without testing (Okay Im reckless and impatient, but Im also the fool who did plug 4 1.5AAs in to charge and survived). It works for both the Z and a nokia (with a custom head). I managed to grab hold of a friend with a multimeter, and found that when plugged to a usb charging cable, the voltage is around 5.4V. Couldn't get a reading when the battery is by itself although i tested it to work.

In regards to the squealing/shutdown issues...
Look at the link rebski provided:
http://www.geekstuff4u.com/product_info.ph...products_id=233 (http://www.geekstuff4u.com/product_info.php?manufacturers_id=&products_id=233)
You will see various ratings. Under battery life it lists the output as 5 volts with a capacity of 1 amp hour (1000 mAh). So you get 5 volts at one amp for one hour (or 5 volts at 1/2 amp for 2 hours, etc)
Looking at the battery capacity rating, you see 3.7V 2000 mAh. This means that the internal battery is rated to deliver 3.7 volts @ 2000mAh.
To get the 3.7 volts to 5.0 volts there has to be some sort of DC - DC convertor involved. These typically use PWM (Pulse-Width Modulation) and in some designs the frequency of the PWM is in the audible range (in other words you can hear it).
They also have internal shutdown circuitry should the load get too high.
Hope this helps.
For anyone ambitious...

However ambitious I might be that is way beyond my capabilities but I shall keep it for reference.
BTW I actually have one of these
http://www.laptopsforless.com/pr2details.htm (http://www.laptopsforless.com/pr2details.htm)
Although not particularly cheap ($60) it is very versatile with selectable voltages of 3, 4.5, 5, 6, 7.5 and 9.
This makes it very versatile.

Just a note, but it seems that the Pelican PSP battery doesn't like (gets hot and the LED blinks really fast) charging off 5.4V, like an Axim power supply.
-
It gets hot and blinks the light really fast when charging off my zaurus charger EA70 as well.
-
the pelican cigarrete cahrger puts out 5.4 v at around 1.5 amps. i havent tried it myself because as it is, the ea-70s charger the pelican and it blink fast(normal) until its solid(full charge).
it does get warm which is normal as long as your zaurus charger doesnt get hot even the plug, its fine.
-
well, I bought the Joytech PSP battery extender for my PSP and it has a Ni-MH battery inside, rated at 4.8V output with 2000mAh. The input is 5V 2A which is the same as the charger for my C3100. The plug is the same size too so I think its ok to use with my C3100.
Strangely, my C3000 charger is 5V 1A and my C3100 charger is 5V 2A (both came direct from japan in original packaging). Been using my C3000 charger with my C3100 because its smaller
-
i have been charging off psp chargers for awhile with no ill effects, people have charged there psp's from the zaurus charger as well so i dont think there would be a problem
ethier way i boght 2 6000mah battries that were for use with the psp, cant wait to try them out

Has anybody tried the Logc3 External Battery (http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10065741&catid=22444#)? Only $25 (CDN). I'm going to pick one up later today.

FYI Of course after buying the logc3 & saw a the pelican at a walmart for $3 more. The logc3 is a 1800mah lion, while the pelican is a 3600mah nimh. The pelican is also much slimmer, that with the exta capacity convinced me to return the logc3 & get the pelican.

So I got the Pelican brick and a psp power supply, but after 12 hours the light is still fast-flashing. Is the first charge supposed to take a long time?

Ok, so I left it charging while I was @ work & it was fully charged when I got home. Works good as far as I can tell. The real test will be when I'm on the road watching videos (another thing I'm trying to get working; another thread ).

I saw a hand crank flashlight w/ a power out for cell phones.... maybe this would be a good addition? (needs testing, of course). The power brick is OK, but on my 6k the whole thing got a bit flaky when both batteries got low.

Heads up peeps. FIRE IN THE HOLE!!!!!
Just a bit of a warning to those using the PSP power brick from Pelican. Seems they're being recalled as a fire hazard...
http://www.consumeraffairs.com/recalls04/2...ican_power.html (http://www.consumeraffairs.com/recalls04/2006/pelican_power.html)
Would want any homes or loved ones or heaven forbid, and Zauraii getting imolated...
Take care all!

ouch! definetly bad. I did notice that with mine, the c3200 ran okay but on the sl5500, generated so much heat that i was afraid to leave it alone charging. So i dont use the powerbrick anymore and dont really need it since the zaurus battery is good enough. Ill be tossing the brick to the trash just to be safe.
recall site [a href=\"http://www.powerbrickrecall.net/]http://www.powerbrickrecall.net/[/url] but i dought it will not work for us.
thanks tsing!!

[there are now so many other psp external batteries that the pelican can be pretty much ignored. Mine is in a desk drwaer..and a 3800mah batter is in my "zaurus bag"

Perhaps people could list external batteries they recommend for those now abandoning the Pelican? I'm interested in 3600mah or greater.

1). oooops mine is 3600 mah
Dragonplus. Works well so far. (about 2 weeks)

My battery fired itself on the second charge, and I didn't get a chance to retrun it to the store during the return period. I think I'll get the X-Box controller for the replacement product.

Thanks Tom61 for the Pelican battery warning. (I had bought 2 of these, and they worked great at first.) Then one day it just stopped charging the Z! It didn't get hot or anything. It just stopped charging the Z. A quick check with the multimeter showed it putting out 5.6 volts. That's a little high, and I guess the Z has some kind of protection circuit built in, because it would not charge from the Pelican battery but still works fine with the AC adapter. Now I'm back to my 4 AA NiMH battery pack, which still works fine. It's just heavier, and I have to take the batteries out to charge them.

Anybody else notice that when you register the product selection is set up with radio buttons that only allow one selection. So how do you get your whole $20 worth?

Actually, you have TsingTao to thank for the warning. I was just pointing out that you can something that will probably work for the pieces of junk.

Isn't one of the wireless controllers valued at $21? Still, loosing only $4, instead of the full $20, and getting a X-Box controller I can use is worth it in my opinion. I certianly wouldn't go with the screen protectors, though.

Oops, sorry. Thanks to TsingTao then.

Until I find an acceptable alternative, I'm keeping mine. The first PB I bought went up in smoke (literally). I took it back to Best Buy and the clerk could smell the plastic burning odor even after I carefully put it back in the bubble pack. It was working fine until I decided to test out to see if it would charge and re-charge simultaneously... then poof! The next one I bought, I have not done that with and am still using it frequently without problems. I won't be leaving it unattended while charging though. Hopefully it doesn't explode on me. Thanks for the heads up! I noticed it gets a little warm when charging my 5500 but not too bad. I can't seem to find too many alternatives above 3600mah. Here is one:
6000mah $49.95 USD; confirmed to work with Zaurus:
http://www.lik-sang.com/info.php?category=...oducts_id=8236& (http://www.lik-sang.com/info.php?category=307&products_id=8236&)
Très expensive for a battery, no? I'd kind of like the Pelican all-in-one case which might work for the Z and possibly the car charger if it works.
-
3.6V / 6000mAh ?€???
Zaurus need 5V to charge!

Just got my form and prepaid envelope. It turns out the radio buttons on the website only match up for the primary product, and you get a secondary product to bring the value to around $20. Example: The X-Box pad valued at $14.95 gets paired up with a PSP Screen Guard Pak valued at $4.95.
I've got a scan of the form if anyone wants to look at it.
