Festool PHC 18 Mobile Phone Charger is a compact charging adapter that turns a Festool 18 V battery pack into a portable power source for smartphones. This is a phone charger designed for charging mobile devices on jobsites, in workshops, and anywhere you do not have a wall outlet nearby. Model number 577155, it gives Festool users a simple way to keep a phone powered up without adding a separate power bank to the kit.

The big draw here is flexibility. The charger supports three charging methods at once: a USB-C output, a USB-A output, and a Qi-compatible wireless charging surface. In practical terms, that means one person can drop a phone on top for wireless charging while two more devices charge through cables. If you work with plans, service apps, photos, laser setup tools, or crew communication on your phone, that matters more than it sounds. Dead phone batteries slow down work fast.

Festool did not make this like a generic consumer gadget. The PHC 18 is shaped to work with the brand's 18 V battery packs the same way a cordless tool would, so it fits into the system instead of feeling like an afterthought. The rubberized top helps keep a phone from sliding around during inductive charging, which is a practical detail if the charger is sitting on a workbench, window sill, or tailgate instead of a clean office desk.

Charging performance is also laid out clearly. The USB-C port delivers up to 15 W, the USB-A port delivers up to 12 W, and the inductive charging surface supports 5 W and 9 W operation with Qi-BPP/PPDE compatibility. That gives you options depending on the device and the cable you have with you. If your phone supports wireless charging, you can skip the cable entirely. If you need a direct wired connection, both common USB output types are built in.

For users already invested in Festool cordless tools, the system fit is the real selling point. The PHC 18 works with Festool 18 V Li-ion battery packs, with the stated exception of the 3.0 Ah and 3.1 Ah Ergo battery packs. That compatibility lets you use the batteries you already carry for drills, saws, lights, and other cordless tools. Instead of packing a separate power bank that needs its own charging routine, you can pull from the same battery platform already in your van, trailer, or Systainer stack.

Festool also calls out real-world runtime. With a fully charged 5.2 Ah standard battery pack, a smartphone with a 3000 mAh battery can be charged up to eight times. That is the kind of detail that helps on long service calls, all-day installs, punch-list work, or travel between jobs when access to power is unpredictable. You are not just topping off a phone once. You are getting repeat use from a battery you likely already own.

The physical size is another plus. At roughly 4.9 inches long, 3 inches wide, and 1.5 inches high, the charger is small enough to stash in a Systainer, drawer, or tool bag without wasting space. It weighs about 0.4 lb, so it is easy to keep around full time instead of leaving behind. That makes sense for techs, installers, and contractors who rely on their phone as much as they rely on their tape measure.

If you already run Festool 18 V tools and want a cleaner, tougher alternative to a regular consumer power bank, this is the right piece. It is especially useful for carpenters, installers, finish crews, punch-out work, service techs, and anyone who uses a smartphone constantly through the day. If you do not use Festool 18 V batteries, this accessory does not make much sense. If you do, it is one of those small add-ons that solves a real problem every week.
