I picked up some Joe Rocket battery powered ones, but honestly don't recommend 'em.
Don't get me wrong. The gloves are OK, or rather the second set is.
Dealing with Joe Rocket for the RMA on the first, defective, pair was a long drawn out nightmare of bad communication, obfuscation, & bureaucratic BS.
Basically my Amazon vendor was pretty minimally helpful, so pretty marginal, & Joe Rocket was horrid.
That said, battery gloves are great, but limited by the battery, so for my commute of ~10-20 min they do OK, but for anything much longer than an hour I'd take a hard look at something wired if your electrical system will support 'em (Most do).
Cyclegear has a 101 set that comes with a heat controller for an OK price if ya catch 'em at the right time. Haven't used 'em but they do review OK.
