USB Charge and Sync cables for CLIE TJ-27 -- Zip-Linq
Pc-Mobile cables for PDA, GSM and GPS
I've got a few threads on this topic in earlier blog postings and on usenet. I found this page by searching on the battery specs for my TJ-27 - 5.2V and 800 mA (it can be so hard to find unique search terms for Google work). This site also has a nice selection of CLIE connectivity cables for sale.

Important note: Turn off power management (at least to the USB port), particularly if you are going to charge the Clie via USB port unattended. Otherwise no power will be delivered to the USB port thus no charging current.Here's the result of the research:
Depending on the models, USB charge cable will charge a nearly out of power Clie to about 75% capacity in 3-4 hours (710C may take longer) and the charging rate drops significantly afterwards. 320 (and models with Li-ion batteries) could be charged to nearly 100% in further 3-5 hours, while 710C (Li-polymer battery) can be charged to maximum of about 80% or more.
Power output from Sony AC adapter is 5.7V/800mA, output from standard USB port is 5V/500mA. 5V is just about minimum to be able to trickle charge the Clie while it is being used. It is recommended that the Clie to be turned of while charging.
USB power output from computers varies and most are about 5.0-5.2V (some can deliver as much as 5.3V, in that case, it can charge even 710C to 100%). If you connect it into a hub, the hub must be powered. The computer USB port will not have enough power to operate more than one device as well as providing power for charging.
1. I ordered two CLIE Sync-N-Charge I
ZIP-DATA-P05 / UPC# 724580610410 Zip-Linq cables from PC Connection. The Zip-Linq site states these are compatible with the TJ-25. I am very pleased with them. I think I paid about $24 for the two plus shipping, I should have ordered three of 'em.
2. My TJ-27 does NOT use the 5.7V/800mA battery of the older CLIEs. It's a 5.2V/800mA battery. Since USB output is 5V/500mA this is actually a BETTER match to the TJ-27 than to earlier CLIEs.
I'm not bothered by the charge time. I leave the PC in a special power saving mode I defined (basically running with drive spun down and display off) and let the PDA charge overnight.
This is a vast improvement over the ridiculous contraption that ships with the CLIE. SONY should bundle the Zip-Linq cable with the TJ-27.
