As one of its daily deals, TigerDirect offers the Kensington PowerBolt USB iPad, iPhone, and iPod Car Charger Adapter, model no. K39224US, for $22.99. This $20 mail-in rebate drops it to $2.99. With free shipping, that's $9 under our mention from two weeks ago (which didn't require rebate hassles) and the lowest total price we could find by $12. Features include a LED indicator, 2.1-amp output for iPad charging, and more. Rebate ends today.
