ZED 12V Middle Man Battery Adapter Kit

The ZED 12v Middle Man Battery Adapter kit converts your Milwaukee M18, Makita LXT, or DeWALT XR/FlexVolt 18V / 20V batteries into a portable (12 V output) power supply for job sites, 4WD or vehicle setups, camping, shed/huts, custom applications and more..

Lightweight, durable, and made in Australia, it’s built from polycarbonate plastics, utilising stainless hardware with genuine components and features ZED’s own Smart Low Voltage Disconnect (LVD) for automatic battery protection.

ENGEL fridge test and tips powered by a 12v Middle Man - 32 L fridge set to 4 °C, ambient temperature 26 °C (shade), using 2 × 6 Ah batteries. Testing was conducted with the fridge in good condition (good seals and batteries), the door kept closed, the unit empty and pre-cooled for 2 days prior. Under these test conditions, estimated runtime is approximately 24 hours. Fridges cycle on and off, reducing average current draw, runtimes will vary between different fridge models, sizes and brands.

Features & Applications

• 12 V / 10 A regulated output (13.5 V actual) — run fridges, fans, lights, phone, pumps, Starlink Mini, small electronics and much more.

• Universal battery compatibility — fits Milwaukee 18 V, Makita LXT, and DeWALT XR/FlexVolt.

• ZED Smart Low Voltage Disconnect (LVD) — automatically cuts power before over-discharge while maintaining ultra low idle efficiency after disconnect for Milwaukee & DeWalt adapters. (Makita batteries already have an internal working disconnect)

• Vehicle bypass mode — plugs into the vehicle 12 V power cigarette socket (ignition isolated) to switch between vehicle and power tool battery power via input plug on Middle Man without the need to plug and unpug between drives. (DOES NOT CHARGE)

• Solar-ready — connect a regulated solar panel via Anderson Y-splitter on 'output' of Middle Man for hybrid use. (DOES NOT CHARGE)

• Durable & compact — designed extra thick, strong built polycarbonate engineering plastics, stainless fittings, genuine Anderson plugs hi-quality branded components, internally fused, built-in protection against over-current, under-current, short-circuit, and over-temperature conditions to ensure safe and reliable operation.

• Real-world tested — ideal for tradies, 4WDers, campers/outdoor adventureman, and DIY enthusiests.

Your product is covered by a 12 month Warranty.

Milwaukee M18, Makita LXT and DeWALT XR/FlexVolt 18V/20V batteries all fit. You choose your battery brand at checkout and the adapter is built for that brand's connection. Batteries aren't included.

About 24 hours on two 6Ah batteries, from our own test: a 32L fridge set to 4°C in 26°C shade, pre-cooled, doors closed. Fridges cycle on and off, so real runtime varies with fridge size, brand and conditions. The Middle Man takes two batteries, so it runs longer and pulls more than our single-battery kits.

The regulated 12V/10A output (13.5V actual) runs 12V fridges, fans, lights, phones, pumps, a Starlink Mini and most small 12V electronics. At 10A it's the highest output in the ZED range, so it handles higher-draw gear than the Power Plate or Battle Station.

Yes. ZED's Smart Low Voltage Disconnect (LVD) cuts power before the battery over-discharges, then sits at ultra-low idle draw, so your Milwaukee or DeWALT battery is protected. Makita batteries have their own internal disconnect built in.

It doesn't charge batteries. Vehicle bypass mode lets you plug into a 12V cigarette socket (ignition-isolated) and switch between car power and tool-battery power without swapping plugs between drives. You can also share a regulated solar panel via an Anderson Y-splitter. Both share power to your gear; neither charges the tool battery. (Bypass and solar cables sold separately.)

The Middle Man adapter, a 50A Anderson-to-female-cigarette-socket adapter, a ZED Speed Strap, a stainless double S-hook and a carry bag, plus tool-free mounting hardware. Batteries, fridge and optional cables/brackets aren't included. Designed and assembled in Queensland, 12-month warranty, free express post Australia-wide.
