Luzy's Storage Place via Amazon offers the Francois et Mimi High Output Dual USB 3.1-amp 15.5-watt Car Charger in Blue or Pink for $5.25 with free shipping. (Non-members can spend $25 or more to receive free shipping; otherwise it adds $5.01.) That's $2 under the lowest total price we could find for a similar 3.1-amp, 15-watt car charger sold elsewhere, although we saw a similar item for pennies less three days ago. This charger is compatible with a range of USB devices and features two ports. Note that a USB cable is required but not included.
