Many of you (as myself) have been having problems in charging your Sansa Clips due to low power USB ports (I have a laptop with low power USB). I just wanted to report back to the forum regarding a successful purchase so that you don’t waste your time buying something that doesn’t work.
I tried plugging the Sansa Clip into an ac adapter (400mA) that came with my Katana cell phone and it did not work. It either didn’t charge or did not charge sufficiently. I went to my local CVS drugstore and purchased ($20 US) a Philips PX05006 which is a universal “cell phone” charger. The packaging states Multi-Brand capability and it works great. Also, I guess I should mention I have the latest firmware… My Clip works great in Ubuntu Linux, Mac OS X, and Winblows XP…
When plugged into the ac outlet at home, it reaches 90% capacity in 30 minutes and full capacity in about one hour. The battery was completely drained when I first tried it. You may be able to find one cheaper quite easily, but make sure it is 1000mA 5 volt USB AC.
