Kit for VW conversion

A guy called this evening with questions about this kit he saw on ebay:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&viewitem=&ru=http%3A%2F%2Fsearch.ebay.com%3A80%2Fsearch%2Fsearch.dll%3Ffrom%3DR40%26_trksid%3Dm37%26satitle%3D200208055018%26category0%3D%26fvi%3D1&item=200208055018

After reading about the kit, i think it looks pretty good for the money. My only concern is the charger seems too small (3A?)?

The guy that called is planning on doing a trike with a chopper front and a vw bug back.

What are your opinions on this kit ?

Thanks!
