Once attached to any M18 battery, this power supply delivers fast simultaneous power to personal devices and small electronics.

With its USB-C PD port (45W), this power supply is capable of recharging devices from a fully depleted state to 80 percent capacity faster than traditional chargers, the company says. The power supply comes with an attached metal hook to hang when workspace is limited.
