From time to time I see people asking what to use instead of original charger to charge Zaurus palmtops. Some suggest using Sony PSP chargers, some recommends sync-and-charge USB cables.
I have simpler solution — USB Hub chargers. Recently I bought another powered USB Hub and it’s charger does not fit in any of my left sockets (due to size of plug) so I charge it with original Sharp Zaurus charger. Other way is of course proper too — Zaurus power plug is compatible with many devices ;)
