Has anyone used the Griffin PowerBlock or PowerDuo charger? Need home and car chargers.

I’m thinking of buying the Griffin wall charger (Amazon.com).  I like that you can charge two devices at once (tho I am not sure how you know when each is finished). The description says it is Sansa-compatible, but doesn’t say which players.  Has anyone used this charger?

I’ve also seen the Macally charger recommended in these forums, but I’d like to be able to charge two devices.  (A cheap charger, like the Combi model (http://www.amazon.com/Durable-Flexible-Silicone-Charger-SanDisk/dp/B001BFS0H8/ref=pd\_bbs\_sr\_2?ie=UTF8&s=electronics&qid=1229820872&sr=8-2) is also appealing, but I’m afraid of frying my player.  Has anyone used that?

I have also seen that some people use Blackberry or Motorola chargers.  Our phones are LG phones (one’s an VX8350, I think) – I guess that wouldn’t work?

Thanks!

I see on the Sansa accessory page that the Griffin PowerDuo is listed as being compatible with any Sansa players with 30-pin connectors.  How many pins does the Clip have?  It looks like about 5 to me, if I’m looking at the right part.  Thank you.
