Hisgadget Inc. via Amazon offers the iClever 6.6A 3-Port USB Car Charger (pictured) bundled with the iClever Magnetic Air Vent Mount for Smartphones for $21.98. (Add both to the cart to see this price.) Coupon code "KNKVQKP3" cuts the price to $12.99. Plus, Prime members receive free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $6.18.) That's only $3 above the lowest total price we could find for the charger. The 33-watt charger works with most USB-equipped devices; the phone mount uses a rubber clip to attach to your car's air vent, then magnetically holds your smartphone in place.
