You might not have realised it but you can charge your PS3 controller by plugging the USB charging lead into a bog standard USB port on a PC or Mac.
No need to have the PS3 powered up and draining your household electricity. Much better to use that PC you’re checking your email on and browsing the net. 🙂
Yes, I’ll freely admit I hadn’t thought of this, mainly because the controllers last quite a while and it’s usually when I’m playing a game that I notice there’s one bar of power left.
