No more empty smartphone batteries: The PHC 18 phone charger acts as a clever adapter that transforms every Festool 18 V battery pack into a power bank (with the exception of 3.1 Ah Ergo battery packs). No more searching for an available outlet or worrying about whether your smartphone battery will last until the end of the day: This means that your mobile phone is always ready to use. In addition, despite its compact design, it can supply up to three smartphones with power at the same time both via users own charging cables and inductive charging.
