I have tried these two (Home & Car) chargers with my Zen V 1GB player and they didn't charge it at all. When I contacted the shop (very good customer service), they sent another two chargers and they didn't even charge my player. So I bought the original Creative ZEN Power Adapter for £18.23 and it works now perfectly.
Moral of the story is that some things are too cheap... Buy something better for a bit more.
I've a older spec smaller Zen V Plus (4 Gb, Black with Blue trim). This charges perfectly fine from a USB to PC cable. This plug does not charge the Zen V Plus. It turns Zen on when plugged in, but the player does not charge (left for one hour, and then overnight with no effect). I've also got a newer type large Zen V Plus with the bigger screen (4 Gb with Micro SD Card slot). This does charge, but it takes 24 hours to fill to full power, when it only takes 4 hours empty to full on a USB PC Cable. This charger just seems to be underpowered and insufficient for charging.
This is a product that does not do what it claims. How it can be listed to do a job that has not been tested amazes me. The seller has offered a refund, but it is a hassle to have to send it back and wait for a refund for the sake of such a relatively small amount, or is this the idea anyway as most people probably could not be bothered!!!!
