The PowerPort 2 includes two ports, one standard USB and a USB-C port (it can charge your MacBook!) to charge your devices. It’s basically future-proof. Better still, there’s a USB-C to USB- 3. 1 adapter included, if you need to charge two devices the old school way.
The PowerPort II usually sells for $40, and it’s currently on sale for $25, which would be an all-time low price on its own. But if you clip the $3 coupon on the page, you can get it for even less.
