• Absolutely! Just plug the charger in and use the two USB ports to charge up to two devices simultaneously. Works like a charm. When it is being charged, the charging takes longer (even overnight), but the two devices will charge and the PNY will also charge. Note that one port is fast and one is slow. If this is only for backup, the slower port (labeled as One Amp) should be fine, leaving the other port (2.4 Amps) available for charging cell phones and items that you need to charge more quickly.
