I'm thinking of getting a gamepad. After a little seaching i came up with a Logitech Rumblepad II, which comes in both wired as wireless.
Wireless is very tempting of course, but... how about power usage? Logitech claims app. 100 hours, but that of course is when using alkaline cells. What about rechargeable cells?
I mean, i have a Logitech Cordless Optical Mouse as well. I love it to bits, but it's quite hungry for power. When on alkaline cells it lasts several weeks, but when using rechargeable cells, it dies after some 15 hours of use. :doh:
The battaries i use are brand new Philips Multilife 1800 mAh cells. Thing probably is that rechargeable cells only supply 1.2Volts, where alkaline cells come up with 1.5Volts. When in use, the voltage of a battery slightly runs back. My mouse appearently needs at least 2.4Volts to work, causing it to fail only hours after installing new accu cells. Alkaline cells provide 3 Volts, allowing much longer use before the critical low in voltage is reached.
How about this wireless Rumblepad, does it work properly (and most important: does it last) on rechargeable cells??? If not, i think i'd rather choose one that actually comes with a wire anyway :rolleyes:
