The Belkin USB Sync Charger provides synchronization and power for your Compaq iPAQ H3800 handheld with the same cable. Now you can transfer your data without a bulky cradle and charge your handheld through any powered USB port. An included USB cigarette lighter adapter converts the cable into a car charger for use in your vehicle.

REVIEWS:
1) Image wrong, but item works anyway: The image shows a plain wire, but the wire delivered has an annoying clump with a dubious switch in it. Still, it works fine with my rx1950, my son"s h4150, and my wife"s h1940.
2) Excellent product, terminator for HP"s no power cradle: Very excellent product works very well with my ipaq 1935, and wokrs as both USB syn cable and battery charger. After I got this, I regreted deeply that I bought a HP cradle from OfficeDepot two months before this, which has no USB power supply function.

I strongly recommended this to any ipaq 1935 users.
3) Three accessories in one compact unit: Works great with my iPAQ h1935 model. It charges iPAQ from any computer with available USB port.
Great value for $12. More convenient to use then the original sync cable that came with h1935 unit. Replaces your desktop charger, car charger adapter and USB sync cable. The cable has a very convenient switch(not shown on the picture) which toggles beetween charging and syncronization modes.
In comparison:
HP car charger adapter will cost you around $29
HP Desktop charger -- another $27.
