Generally, a club rechargeable has multiple advantages in my mind, one being there is hope they help stop people walking away with them if they are no use to anyone but a club, also people here have nitro cars with sealed receiver boxes and/or receivers in balloons etc, making use of a plug in harder.

But more than anything, just ease of use for a club, and hopefully to retain something people won't want to keep, because I see all sort of issues with leading out personals, and basically never getting them back again, with them being real easy to sell.
