Makita Compatible Double Battery Adapter

Unlock more runtime and added versatility with the Makita Compatible Double Battery Adapter.

Specifically designed for Makita 18V lithium batteries, this adapter not only allows you to connect two batteries at once to your Volt Dropper, but also features a built-in USB outlet to keep your devices charged while you’re off-grid. Perfect for camping, 4WDing, or worksite power, it delivers the rugged reliability Makita users demand.

🔋 Best Use Practice Guide

To get the best performance and longevity from your Double Adapter:

• Use matching batteries – Always pair batteries of the same brand, voltage, and capacity (e.g. two 18V 5.0Ah Makita packs).
  
• Check charge levels – Make sure both batteries are at a similar charge level before connecting (within about 0.2–0.3V).
  
• Avoid mixing new and old batteries – Different internal resistance can cause uneven discharge and reduce performance.
  
• Keep connections clean and secure – Ensure terminals are free from dust, debris, and corrosion for reliable power transfer.
  
• Disconnect after use – Unplug batteries when not in use to prevent slow drain or accidental load.
  
• Monitor temperature – Batteries should stay cool during operation. Stop use if packs feel unusually hot.
  

When used correctly, your Double Adapter safely doubles runtime and reduces strain on each battery — giving you longer, more efficient power for your gear.

Q1: Does this adapter charge my Makita batteries?
No. It is an adapter only. It allows your Makita 18V batteries to connect to the Volt Dropper but does not charge them.

Q2: Can I mix Makita batteries of different sizes (e.g. 3Ah and 6Ah)?
Yes. The adapter will function with batteries of different capacities, but performance is best when using two of the same size and charge level.

Q3: Will this work with Makita tools directly?
Yes, however, this adapter is designed exclusively for use with the Volt Dropper, not for powering tools.

Q4: Can I use just one battery?
Yes. The adapter will work with a single Makita 18V battery, though connecting two will give you longer runtime.

Q5: Does the USB outlet work without the Volt Dropper?
No you cannot use the USB outlet and the Volt Dropper at the same time.

Q6: Is it compatible with third-party Makita-style batteries?
Yes, most third-party Makita-compatible 18V batteries will work. For best performance and safety, genuine Makita batteries are recommended.

Q7: Is the Volt Dropper included?
No. This product is the adapter only. Batteries, Volt Dropper, and tools are sold separately.
