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


some pictures

some pics

Hi Chesho, some nice pictures, and the Pelican brick looks tempting now someone else has done all the testing work. tongue.gif

I discovered last week that the power adapter for my aging iPaq 3630 also works fine with the SL-C3100 (and therefore presumably the C1000/C3000).

The discovery was accidental, since I had the Zaurus only a couple of days, and had intended to charge my iPaq (both were in need of some power). Without noticing, I plugged the Zaurus in the "wrong" adapter and went to breakfast.

The charging light was as normal and neither the Zaurus or adapter got warm, but I unplugged after 30 minutes, when I discovered my mistake. The iPaq adapter claims +5V 2A, although I cannot check since I don't have a multimeter.

Cheers,
Marcus

Good job! Thanks for testing this for us. I have bought the Pelican brick but have not yet used it - was afraid it had too much volts for my zaurus.

i am testing out the cig lighter right now..


the results are.........................gona post in a bit.

i just tested out the pelican car charger for the psp

I don't recommend pluging this thing into the zaurus

voltage for:
sharp ea-70 aka (s) 5.18v .10-.38 amps (comes in the sl-5500 model)

the pelican psp car charger: 5.40v 1.4amps--I do not recommend this

you see, the 5.4 volts is already a tad high and the amps the chargers from sharp puts out is around .10-.38..fluxuates. 1.4 is passing through many electrons at one point and of course you can charge up your zaurus at a faster rate but dude...it produces alot of heat as well.

I would probably use this item on the power brick. I have not tested this form yet.

verdict is.........Not recommended.

i do how ever have an old bat charger from an unknown company that does put out 5.7v at .5 amps. I am still too scared to try this out myself on the zaurus.

How about this power made by Hama? (Netzteil Zaurus Superklein)
Voltages, amps?

Pulster.de - Sharp Zaurus Zubehoer

Hama.de

Is Sharp's EA-70S better in 230v use?

@Cresho: Have you done electronics before?

the amps stated on the power supply is the maximum current draw for the device, the zaurus actually limits how much current it recives, therefore unless a component in the zaurus fails the device will never accept more current than it can take

as for the 5.4v, i hear that the zaurus is sensitive about plugging the charger in the wrong way (unconfirmed) however most electronics rated for 5v operation will work all the way up to 6v, most are rated at 5% up or down which is 4.75v to 5.25v, but i have yet to encounter an electronic component that doesnt exceed spec by a large amount

basically when you look for a wall socket charger, always go for a regulated (unregulated will give a higher than stated voltage when not operating at the specified load current) charger that matches the voltage statd on the device and matches or exceeds the stated current consumtion for the device, the amount of people who i see that get incorect chargers is incredible, ethier to much voltage (so the have some 'slack' built in for when the device neads more voltage hahaha) or not enogh current

if you dont have a charger that matches the required voltage but have some time and a soldering iorn buy a 7805 and 2 capacitors (electrolitic 10uF) and build your own charger, its simple, theres plans all over the net

I am basing my results from statements from other people's expiriences and from guidelines other people stated. Are you lucky enough to try out 6v @1.5 amps on your zaurus? I sure am not! reversing the polarity does blow your zaurus btw as stated by many who i read in these forums. Also, others stated devices failing with odd chargers. Even sales guys from TRIsoft and Streamlinecpu have said to use the EA-70s chargers and they sell them and I also have read horror stories of people using other chargers for the zaurus and notice zauruses failing with some sort of......
Don't quote me on these but this is what i read and bad of me for not keeping links to these.
So from what i read, few stated the best way to go about this is to stick with the ea-70s.

hmmm

i think i found one link http://www.oesf.org/forums/index.php?showt...060&hl=chargers

so stick with close specs (sharp ea-70 aka (s) 5.18v .10-.38 amps (comes in the sl-5500 model))as possible -- in this case, ill throw the 20% slack out the door. This is exactly what i get out of charger that's pluged into the wall and those are the numbers i am going to use as a basis for other chargers as well. I really don't know what amp output comes out of a european socket.......probably 1 amp but ill never ever know. I read about zauruses failing with 5.4 volts as well. TRIsoft has many expiriences with customers and power problems which causes serious damages to the zaurus and they even said to stick with the sharp ea-70s.

i was not aware of the zaurus failing with 5.4 volts, i would like to meet the person who came up with that power supply and tell him a thing or 2 about consumers who dont know better and use the wrong equipment, i mean come on couldnt they afford to add a voltage regulator and reverse polarity protection

anyway i stand but what i said about current. its perfectly safe to get a ccharger that can supply more current than required by the device. but i guess i will make sure i only get 5v chargers.

The Socket Mobile Power Pack ~ $150 US

http://www.socketcom.com/product/AC4009-541.asp

Works just fine with the Zaurus 6K. It's got 7200mAh of juice and comes with all sorts of adapters for various products. Rated for +5V DC @ 1.8 Amps. The Zaurus EA-70 AC Adapter that comes with the Z6K has an output of +5V DC @ 2.0 Amps. When using the Socket Mobile Power Pack, the Z doesn't pull too much juice (Power Pack would complain if it did by shutting off) and I've used it just fine for providing electricity for my Z.

It is $150 from Fry's Electronics. You can likely find it cheaper. Right now if you buy it somewhere you can get a $25 Rebate from Socket till 9/30/2005.

The one I bought from Fry's already had the adapter for the iPod and it works for the Sony PSP and my Nokia 6230 which needs the included power booster that boosts the voltage to +6V DC @ 300mA (which is the same that the Nokia charger puts out).

I would recommend this power pack as it also comes with a nifty leather case

ouch... hmm... guess if I had more room on my belt I could have just bought two Pelican powerbricks lol... ah well.. it does have a nice lil leather case... tongue.gif

Hmm... with those pelican bricks being that cheap... could probably make a belt that had them going all the way around and connect them in parallel to have limitless power.. lol... hmm.. well maybe do half and half in series and connect those in parallel... so you can draw more amperage and still have reasonable life...

course I"d probably need some suspenders to keep my pants up LOL

check this out...

Attached File  zrearrt2570best.JPG ( 318.49K ) Number of downloads: 43


The DC to DC Converters are Acer N35 PPC Power Units yielding 5.13v @ 600mA and are great at powering the USB 1.0 Hub with ONE
peripheral, in this case a heavily modified Linksys WUSB54G v4 Wifi Card. Note the cooling system in place on the card thats a 12v fan BTW, GND
is connected to the top of its USB Socket, the other fan wires are connected to the Jumper clip on the battery's +VE terminal. This is all required
as the DSP chip in the USB card burns out if its not fitted, below the fan is a large metal heatsink plonked on top of the DSP chip.

So, you can order the Acer Cigarette Lighter DC Power Adapter for the Acer N35 GPS Windows PPC Computer and this will happily
power an SL-C1000 from a 12v Lead Acid Cell. As you can see, I have 2 of them running the system: one for the Computer and one for the
Hub and Wifi card.

Have Fun !
