shipping\'s $4.99, but it\'s still a good price.

Try this guy. Phenominal prices, service and combined shipping:

(even sent me a new one when mine stopped working)

No assocaition, just a satisfied customer.

BTW, he has extenders, AC Adapter, and car adaptors....remember, never start your car with Z in car charger...and he combines shipping.

FWIW, I\'ve been very happy with my extender - it\'s a little bulky, but much better than not having a Zaurus when traveling.

It\'s cheaper to make one out of Radio Shack parts. Total cost will be less than the shipping on these things.

I\'m up for a do-it-yourselfer, can you post a part list ! :wink:

Thanks,

Can you confirm that it works only with rechargable batteries?

I like this one as it powers either through the USB port, or the DC jack, and cool slim design which sort of matches the Cxxx series:

It\'s been a while, so I don\'t know the Radio shack PNs, but basically, all you need is
1) 1 Battery holder for 4 batteries. Take your pick of battery size.
2) 1 tip. They come in 2-packs, and Radio shack has a lettering scheme for different sizes, I forgot which size it is, but it shouldn\'t be too hard to figure out. If you bring your Z to the store they can find the right one.

Solder the leads from the battery holder to the tip and that\'s it! You\'ll get 4.8V from NIMH batteries, or 6V from alkies. (you can add a diode to drop the voltage if you want)

I made my own including a diode so I could charge it from the car (4 Ds) and with a Y connector to do both my Z and GPS.

cmisip · « **Reply #9 on:** May 16, 2004, 10:24:13 pm »

I bought one from ebay but it wont charge the Z because I was told, I was using regular nonrechargable batteries. How hard would it be to put a diode in the battery extender so I can drop the voltage to 5V? I dont know much about electronics. Can you elaborate?

Hi cmisip,

Get yourself some rechargeable 2300mAH NIMH batteries, and a charger. Almost as much power as non-rechargeables but will save you a lot of money.

If you still want to use the regular nonrechargable batteries, then you have to cut one wire on your battery extender and place the diode inbetween. A regular rectifier diode, e.g. 1N4001 should do. You can only put it in one of two ways and if you put it in wrong, it doesn\'t work and you just change the direction.

cmisip · « **Reply #11 on:** May 17, 2004, 09:30:00 pm »

omega,
that diode sounds so familiar to me, is it the same type used in bridge type power supplies? Once worked on a project like that in elementary school to convert AC to DC. I would have thought to use a resistor though, but after some reading, I find that there is an inherent voltage drop with a diode due to internal resistance. Thanks a lot for your advice, I shall give it a try.

Got it thanks I went with the 4 NIMH batteries!

How many hours extra would the 4 NIMH batteries give a person?

How easy is it to find a 3rd party power adapter that I could use at my place of work instead of a home made battery pack to power my Z5500 at my desk?

I use a AC adaptor from a iPac 3650, same power rating as the Sharp supplied adaptor.
