The Milwaukee® M18™ Top-Off™ 175W Power Supply delivers faster simultaneous power to personal devices and small electronics. Attach any M18™ battery to provide continuous power or recharge devices with (1) AC 120V outlet, (1) USB-C PD port and (1) USB-A port. You can quickly charge up to three devices at the same time, without the barriers of speed throttling. With the USB-C PD port (45W), this battery inverter is capable of recharging devices, from a fully depleted state to 80% capacity, up to 75% faster than conventional wall chargers (5W). The Milwaukee compact portable power supply has an attached metal rafter hook that can be extended to hang it from carts, lumber or other jobsite materials when work surface space is limited. You can instantly set up a mobile workstation or keep electronics securely within eyeshot, rather than making frequent trips to a wall outlet. Includes one M18 5.0Ah battery.
