Q:i spent so much buying rechargeable batteries for my player (4 pcs size AA). i cannot wait charging the batteries especially when i am on the go. i want a portable battery pack which i can take along when i go out. my player requires only 9v. playing video at long hours easily consumes the charge that's why i am looking for a battery pack which lasts longer.

Battery packs are usually built in but an adapter to work on 120vac or 12vdc just plug in. You can DIY a battery pack to work at the adapter plug in.

Q:I am tired of my AA batteries running out every few days.Someone got me a Wii starter kit that came with all sorts of goodies, including 2 rechargeable battery packs. They look just like a normal battery packs but where AAs go there is a little pack that says Rechargeable Battery Lithium Polymer Battery.I snapped this onto the remote, then plugged a USB cord directly from the rechargeable pack to the USB outlet on the Wii. The Wii remote showed no signs of life, no lights flashing, nothing, even when I held the power button.I hooked up to my PC and wall USB plug, and I also tried all three with the pack on its own, not snapped into the remote. Nothing gave any indication that charging was taking place.So what's the deal? How do I use this rechargeable pack? Thanks

Q:I have Rock Band drums that take 3 AA batteries and I don't want to waste batteries. Is there a way to make something that plugs into the wall and connects to the battery sockets (1.5 volt)?

I assume there's no external power connector on your drums (bad design in my opinion). There are some products in the market that do what you say, but they are specially made for specific devices such as professional flashes and cameras. The problem is that each battery compartment is different, and you also have a problem with the door. I think you're way better off by getting a good set of rechargeable batteries and a wall charger. Buy brand (Energizer, Sanyo, etc), you'll save money in the long run.
