Connect flashlights to rechargeable battery supply

[romeroom]

I have approximately 10 small LED flashlights: http://www.harborfreight.com/3-12-in-9-led-mini-flashlight-69111.html Each of these is powered by 3 AAA batteries.

I would like to connect all of these to a single rechargeable power source (battery) and then to a switch so I can turn them all on at once.

Suggestions?

Thanks.

Omar
