-
Use the battery you already own: this battery inverter turns an 18V-20V tool battery into AC power for laptops and phones

Never run out of ports: an AC outlet, USB-B, Type-C and 12V DC port each get their own connection
-
Leave it running with confidence: built-in overload and overheat protection keeps the power safer
-
Pack it without a second thought: at just 0.74 lb it barely adds weight to a bag
-
Stay powered away from an outlet: camping, hiking and emergency backup power are covered with one DC to AC inverter
Your tool batteries do not have to sit idle between jobs. This portable power inverter clips onto an 18V-20V tool battery and turns it into a wall-style power source, so a laptop, phone or camp light can run off the same pack that drives a drill. It ships in US and EU plug versions and in battery-specific variants for Makita, DeWalt and Milwaukee packs, so it connects straight to the batteries already on the shelf.
Inside, the inverter steps the battery's DC output up to 110-120V AC and pushes it out through four ports at once, so more than one device can draw power at the same time. Overload and overheat protection watches the load the whole time it runs, and at 0.74 lb (0.3 kg) this battery power inverter rides in a bag pocket instead of a toolbox.
